Transjugular intrahepatic portosystemic shunt, local thrombaspiration, and lysis for management of fulminant portomesenteric thrombosis and atraumatic splenic rupture due to vector-vaccine-induced thrombotic thrombocytopenia: a case report



Recombinant adenoviral vector vaccines against severe acute respiratory syndrome coronavirus 2 have been observed to be associated with vaccine-induced immune thrombotic thrombocytopenia. Though vaccine-induced immune thrombotic thrombocytopenia is a rare complication after vaccination with recombinant adenoviral vector vaccines, it can lead to severe complications. In vaccine-induced immune thrombotic thrombocytopenia, the vector vaccine induces heparin-independent production of platelet factor 4 autoantibodies, resulting in platelet activation and aggregation. Therefore, patients suffering from vaccine-induced immune thrombotic thrombocytopenia particularly present with signs of arterial or venous thrombosis, often at atypical sites, but also signs of bleeding due to disseminated intravascular coagulation and severe thrombocytopenia. We describe herein a rare case of fulminant portomesenteric thrombosis and atraumatic splenic rupture due to vaccine-induced immune thrombotic thrombocytopenia.

Case summary (main symptoms and therapeutic interventions)

This case report presents the diagnosis and treatment of a healthy 29-year-old male Caucasian patient suffering from an extended portomesenteric thrombosis associated with atraumatic splenic rupture due to vaccine-induced immune thrombotic thrombocytopenia after the first dose of an adenoviral vector vaccine against severe acute respiratory syndrome coronavirus 2 [ChAdOx1 nCoV-19 (AZD1222)]. Therapeutic management of vaccine-induced immune thrombotic thrombocytopenia initially focused on systemic anticoagulation avoiding heparin and the application of steroids and intravenous immune globulins as per the recommendations of international societies of hematology and hemostaseology. Owing to the atraumatic splenic rupture and extended portomesenteric thrombosis, successful management of this case required splenectomy with additional placement of a transjugular intrahepatic portosystemic shunt to perform local thrombaspiration, plus repeated local lysis to reconstitute hepatopetal blood flow.


The complexity and wide spectrum of the clinical picture in patients suffering from vaccine-induced immune thrombotic thrombocytopenia demand an early interdisciplinary diagnostic and therapeutic approach. Severe cases of portomesenteric thrombosis in vaccine-induced immune thrombotic thrombocytopenia, refractory to conservative management, may require additional placement of a transjugular intrahepatic portosystemic shunt, thrombaspiration, thrombolysis, and surgical intervention for effective management.

Peer Review reports


SARS-CoV-2-vaccine-induced immune thrombotic thrombocytopenia (VITT) represents a rare complication after vaccination with adenoviral vector vaccines, with incidence from 1 case in 125,000 to 1 case in 1 million [1, 2]. So far, most such patients have presented with signs of arterial or venous thrombosis at atypical sites, but disseminated intravascular coagulation (DIC) has also been described to be associated with vector vaccines [1,2,3,4,5,6,7,8,9]. It is assumed that VITT is caused by the production of autoantibodies against the complex of platelet factor 4 (PF4) and an as-yet-unknown polyanion found in recombinant adenovirus vaccine [10]. VITT occurs around 4–28 days post vaccination, and frequently this disease takes a fatal course [3, 11, 12]. This report describes a severe case of VITT complicated by extended portomesenteric thrombosis associated with atraumatic splenic rupture, an extremely rare complication of VITT. To the best of the authors’ knowledge, this is the first description of such a case involving therapeutic anticoagulation, treatment of hemorrhagic coagulopathy, application of intravenous immune globulins, splenectomy, TIPS placement, thrombaspiration, and thrombolysis for effective management of VITT.

Case presentation

Patient information and initial clinical findings

We report the case of a healthy 29-year-old Caucasian, married, male patient with no major past medical history except Vitiligo’s disease presenting with signs of vector-vaccine-induced thrombotic thrombocytopenia (VITT) 11 days post vaccination with an adenoviral vector vaccine against SARS-CoV-2 [ChAdOx1 nCoV-19 (AZD1222)]. The patient had no history of exposure to tobacco, alcohol, or drugs and presented with an unremarkable family, environmental, employment, and psychosocial history. He exercised regularly and was on a vegetarian diet. The patient did not take any chronic medication and had no known allergies. He presented 11 days post vaccination to the outpatient emergency medical service with nausea and abdominal pain progressing for the previous 2 days. On physical examination the patient was fully orientated [Glasgow Coma Scale (GCS) 15] without any neurological pathologies and showed stable vital parameters (respiratory rate 15/minute, SpO2 97%, heart rate 80/minute, blood pressure 123/62 mmHg, body temperature 36.7 °C). He was consecutively discharged, being suspected of suffering from food poisoning. However, the patient’s condition deteriorated, resulting in hospital admission the next day with symptoms of vomiting, hemoptysis, melena, fever, and deteriorating health condition. His blood pressure was 90/60 mmHg, his heart rate 100/minute, his respiratory rate 25/minute, his SpO2 97%, and his body temperature was 36.9 °C. Presenting with a GCS of 15, there were no pathological findings on neurological examination. The patient’s full blood count on admission showed severe thrombocytopenia (13,000/µl).

Initial clinical management

The patient was transferred to the intensive care unit (ICU). An abdominal computed tomography (CT) showed free perihepatic, perisplenic fluid and active endoluminal bleeding at the ileocecal passage (spot sign). An esophagogastroduodenoscopy and colonoscopy were performed, detecting a congestive gastropathy and hemorrhagic gastritis with no signs of active bleeding. The patient received an intravenous proton pump inhibitor (40 mg pantoprazole intravenously). Anemia and thrombocytopenia were treated by transfusion of 4 units of red blood cells (RBC) and 2 units of platelets (PLT). Due to the lack of the past medical history of the patient regarding his vaccination, autoimmune thrombocytopenia was suspected, and a dose of intravenous corticosteroids was given (500 mg prednisolone). The next day, the patient developed hemorrhagic shock. The patient was intubated and sedated with intravenous propofol 2% (2 mg/kg/hour) and sufentanil (30 µg/hour) infusion and required continuous infusion of noradrenaline (0.2 µg/kg/minute) to stabilize his blood pressure. Spontaneous atraumatic splenic rupture, diagnosed on abdominal ultrasound, required emergent exploratory laparotomy and splenectomy. The small intestine presented with ischemic demarcation. Due to extended coagulopathy, intraoperative blood loss of 3 liters required massive transfusion of 8 units of RBC, 2 lyophilized units of plasma, 2 units of PLT, 1 g tranexamic acid, 2 g fibrinogen, and 1800 units of prothrombin complex. The abdomen was packed and left open. With persisting hemodynamic instability and hemorrhagic coagulopathy (see laboratory values in Table 1), the patient was transferred (intubated and sedated) to our tertiary hospital ICU (University Hospital of Cologne, UKK; see timeline of VITT in Fig. 1). Another abdominal CT detected dilated small intestine with edematous thickened walls and occlusion of the portal, splenic, and superior mesenteric vein (Fig. 2A). Colleagues from the Department of General Surgery and the Department of Radiology decided conclusively due to the extended thrombosis to firstly reduce the venous congestion and restore portomesenteric blood flow by thrombectomy and placement of a TIPS: A 10 F sheath was inserted via the right jugular vein, and 5000 units of unfractionated heparin were injected intravenously. A thrombectomy catheter was inserted via the TIPS into the superior mesenteric vein (Fig. 2B, C), and an interventional aspiration thrombectomy and local lysis therapy was initiated: a bolus of 10 mg tissue-type plasminogen activator (rtPA, Alteplase) followed by continuous intravenous infusion of rtPA (at a rate of 1.5 mg/hour). During the procedure, there was another blood loss of approximately 1 liter, requiring the transfusion of a further 3 units of RBC and 2 units of PTL. Blood pressure was stabilized with continuous intravenous noradrenaline (0.4 µg/kg/minute) and vasopressin (2 Units/hour) infusion. The intravenous dose of pantoprazole was increased to 160 mg (continuous infusion) per day for the next 3 days. Due to the suspicion of ventilator-associated pneumonia, treatment with intravenous piperacillin/tazobactam was initiated (3 × 4.5 g/day) for 7 days of treatment. Microbiology screening of tracheal secretions revealed small amounts of Serratia liquefaciens (sensitive to piperacillin/tazobactam) and Candida albicans. Under antimicrobial treatment, inflammatory markers decreased and respiratory function improved.

Suspicion of VITT: diagnostic assessment and therapeutic intervention

Parallel to this intervention, the patient’s past medical history revealed that he had received his first vaccination dose of a vector vaccine (ChAdOx1 nCoV-19 (AZD1222), AstraZeneca) 14 days before. This finally raised suspicion of VITT, and intravenous immune globulins (IVIG) were administered to the patient: 80 g IVIG (1g/kg body weight Octagam®; Octapharma GmbH, Langenfeld, Germany, for the patient’s body weight of 80 kg) for two consecutive days. Before administration of IVIG, blood samples were taken for immunologic assays for heparin-induced thrombocytopenia (HIT) type II, thrombocytopenia, and thrombophilia screening (Table 2). Anticoagulation was managed with a direct thrombin inhibitor (argatroban with dosage of 0.15–0.25 µg/kg/minute). Coagulation screening [blood count, plasmatic coagulation, thrombelastometry (ROTEM)] was run 6-hourly. A rapid HIT II screening test (ID-PaGIA heparin/PF4-antibody test kit, Bio-Rad Laboratories GmbH, Feldkirchen, Germany) showed a negative result. An IgG-specific enzyme-linked immunosorbent assay (ELISA) (Immunocor GTI Diagnostics, Inc., Waukesha, WI USA) was positive (odds ratio 2.35). With hemodynamic stabilization of the patient, continuous intravenous infusion of vasopressin could be stopped and parenteral feeding initiated.

Table 2 Thrombophilia and thrombocytopenia screening

Day 15 post vaccination (see timeline in Fig. 1), another angiography revealed reduced flow in the portal and superior mesenteric vein due to residual thrombus material. A further aspiration thrombectomy was performed, resulting in restoration of hepatopetal portomesenteric blood flow.

On day 16 post vaccination, the abdominal packing was removed, the ischemically demarked parts of the small intestine (190 cm) were resected, and the remaining intestine (approximately 100 cm) was connected in the form of a side-to-side duodeno-ileostomy. As the thrombocyte count continued to stabilize, thrombocyte aggregation could be blocked with acetylsalicylic acid (ASS 100 mg intravenously) to prevent clotting of the essential TIPS. The patient could be extubated, his abdominal pain was sufficiently treated with slow-release oral morphine (3 × 10 mg), and enteral feeding could be started.

On day 27 post vaccination, on the patient’s discharge to the general ward, the thrombocyte count had fully recovered to the reference range. Anticoagulation with the direct thrombin inhibitor (argatroban) was stopped, and treatment with fondaparinux was initiated. On day 31 post vaccination, with the patient’s discharge to the rehabilitation center, fondaparinux was replaced with an oral Xa-inhibitor (apixaban) for at least another 6 months. Due to the TIPS, the patient will remain on lifelong aspirin therapy.

Follow-up and outcomes

The patient remained under monthly immunologic and hemostaseologic surveillance (screening of autoantibodies against PF4 and coagulation parameters). Immunologic analysis (Reference Laboratory for VITT, University Hospital Greifswald, Institute of Immunology and Transfusion Medicine, Germany, Prof. Greinacher) on the day of admission to UKK confirmed the diagnosis of VITT: HIPA test (heparin-induced platelet activation) was negative and PF4-induced platelet activation (PIPA) test (modified HIPA test) was positive. He remains anticoagulated with apixaban for another 6 months, plus lifelong therapy with acetylsalicylic acid for his TIPS. By following a 4-week rehabilitation program including physiotherapy and nutritional advice in the rehabilitation clinic, the patient fully recovered to a Barthel index of 100 out of 100 points and regained mental stability with no signs of anxiety or depression. After rehabilitation, he could return to full-time work at his former job as a purchasing agent for a public broadcasting institution. His socioeconomic situation has not changed due to the disease.


To the best of the authors’ knowledge, this report presents the first case of VITT complicated by extended portomesenteric thrombosis and resulting in atraumatic splenic rupture, which made splenectomy as well as TIPS placement inevitable. This led to a challenging combination: On the one hand, bleeding complications due to hemorrhagic coagulopathy because of splenic rupture and vaccine-induced thrombopenia required administration of clotting agents. On the other, extended portomesenteric thrombosis and the risk of TIPS occlusion necessitated therapeutic anticoagulation and platelet inhibition. This was managed by a broad interdisciplinary approach, close intensive care monitoring, and effective coordination of all treatment measures: application of intravenous immune globulins, adequate anticoagulation in VITT, as well as administration of clotting agents for the treatment of hemorrhagic coagulopathy, an emergency splenectomy, and placement of a TIPS for thrombaspiration and thrombolysis.

Symptoms and risk factors of VITT

Most cases of VITT documented in literature presented clinically with the triad of significantly elevated D-dimers (up to five times the reference range), thrombocytopenia < 150,000/µl, and arterial and/or venous thrombosis (especially at unusual sites), as did our patient. Portomesenteric thrombosis has been described in VITT previously, but not as fulminant as presented in our case with atraumatic splenic rupture requiring TIPS insertion and emergent splenectomy. The triad of symptoms in VITT resembles HIT type II and the more rare spontaneous HIT without heparin exposure [13]. As per the recommendations of international professional societies [14,15,16], clinical trials of VITT presenting 4–48 days (median, 14) [11] post vaccination, mostly after the first dose of vector vaccine, should raise suspicion of VITT and must be investigated accordingly [12]. So far, there are no identifiable risk factors for VITT except the vaccination with recombinant adenoviral vector vaccines itself, with an age range of VITT from 18 to 79 years (median 48 years) and equal gender distribution [17].

Pathophysiology of VITT

Vaccination with recombinant adenoviral vector vaccines can result in heparin-independent production of autoantibodies against PF4 [11]. This PF4/polyanion complex resembles the PF4/heparin complex that is responsible for HIT type II and can therefore be found in VITT without any previous heparin exposure [10]. The binding site of anti-PF4 antibodies of VITT patients is restricted to the heparin binding site of PF4 and can actually be inhibited by heparin [13]. Due to the formation of this PF4/polyanion complex [18], thrombocytes are activated and aggregate, leading to thrombophilia with the risk of thromboembolic events and consumption coagulopathy [20]. As opposed to HIT type II, in VITT, bleeding events as in our case have been described frequently [10, 19]. The existence of PF4/vaccine complexes does not necessary result in VITT [20, 21]. Although a positive test with clinical symptoms increases the likelihood of this diagnosis, in some cases of VITT, PF4/vaccine complexes could not even be detected [22,23,24]. In our case, antibodies against PF4/polyanion complexes could be identified by IgG-specific ELISA, and PF4-related platelet aggregation could be shown by the PIPA test.

Diagnosis of VITT

Laboratory signs of VITT are significantly elevated D-dimers (up to five times the reference range), thrombocytopenia < 150,000/µl, reduced fibrinogen levels, positive PF4 antibodies in HIT-ELISA, and positive functional platelet activation tests (PAT) such as PIPA and serotonin release assay (SRA) test. Radiographic or ultrasound imaging of an atypical thrombosis can be helpful in the diagnosis of VITT [16, 25]. Atraumatic spontaneous splenic rupture is a rare phenomenon in VITT (with only one other case recorded) [26]. The incidence of atraumatic splenic rupture in the general population is estimated to be around 0.1–0.5% [27]. On suspicion of VITT, it is crucial to implement adequate tests. Studies have revealed that rapid HIT assays such as rapid immunoassays (RIA) or chemiluminescence immunoassays (CLIA) should be avoided as they present poor sensitivity (< 20%) for anti-PF4 antibodies compared with IgG-specific ELISA tests (> 99%) [28, 29]. In our case, the rapid HIT screening test also presented a negative result, in contrast to the positive IgG-specific ELISA. Recommendations for the diagnosis of VITT include PAT such as PF4-SRA, SRA, or HIPA testing with sensitivity > 99% for VITT [24, 25, 29]. Additionally, especially in case of a negative HIPA test, a PIPA test with sensitivity of > 99% should be performed [29]. In our case, a positive PIPA test despite a negative HIPA test confirmed the diagnosis of VITT.

Treatment of VITT

The pathomechanism of VITT is not fully understood so far, so no direct treatment option is available yet. Management only focuses on treating complications of VITT such as thrombosis and consumption coagulopathy and reducing the amount and effect of circulating PF4 antibodies.

Due to the similarity of VITT to HIT type II, a potential interaction with heparin cannot be excluded. Pending further data, the use of heparin in VITT should be avoided to prevent any possible interaction. Anticoagulation should be performed with nonheparin anticoagulant agents instead, such as danaparoid, argatroban, fondaparinux, or direct oral anticoagulants [30]. Before suspicion of VITT was raised, our patient also received heparin. Whether this had harmful effects remains unclear [3]. After suspicion of VITT, anticoagulation was established with argatroban, a direct thrombin inhibitor with a short plasma half-lifetime, as the patient remained hemodynamically unstable and coagulopathic. The dose of argatroban was monitored by rotation thrombelastometry (ROTEM, Werfen GmbH, Germany) as studies have revealed that aPTT is a suboptimal marker for dosing direct thrombin inhibitors [31,32,33,34].

Owing to bleeding complications, our patient required massive transfusion, which in general should be avoided in VITT whenever possible. In particular, platelet transfusions increase the risk of antibody-mediated platelet activation and coagulopathy [30].

As our patient stabilized hemodynamically and his thrombocyte count recovered, anticoagulation could be switched to fondaparinux subcutaneously for the general ward and to an oral anti-Xa inhibitor (apixaban) at discharge to the rehabilitation clinic. Current recommendations for patients suffering from VITT include continuation of therapeutic anticoagulation for at least 3 months [5, 15].

Another treatment option for VITT is the application of IVIG [8, 22, 35], which blocks circulating PF4 antibodies from interacting with the FcγRIIa receptor on the surface of platelets, thereby avoiding platelet activation [3, 5, 11, 36]. However, IVIG therapy itself is associated with a risk of thrombosis in up to 13% when used among patients with autoimmune disorders [37]. Our patient was treated with IVIG (2 × 1 g/kg Octagam). Whether this may have aggravated his thrombosis, requiring radiographically assisted re-thrombectomy, remains unclear.

The use of steroids can be considered in the management of VITT, especially in case of delayed availability or unsuccessful treatment with IVIG and plasma exchange (PLEX) [5]. Corticosteroids potentially increase the thrombocyte count faster than IVIG alone in other settings of autoantibody-mediated thrombocytopenia [38]. Our patient initially received a dose of intravenous corticosteroids (500 mg prednisone). The use of alternative immunosuppressants (rituximab or eculizumab, for example) can be considered in cases of VITT refractory to therapy, but evidence for this treatment is lacking so far [15, 16].

Furthermore plasma exchange (PLEX), preferably against plasma rather than albumin, could represent an alternative option for reducing the amount of circulating PF4/vaccine complexes and correcting hypofibrinogenemia [17]. PLEX was discussed but rejected in our management of VITT as IVIG therapy seemed to be effective.

In our patient, portomesenteric thrombosis was too extensive to be treated conservatively. TIPS insertion was crucial for the successful management of VITT to reduce venous congestion and perform thrombaspiration/thrombolysis via the TIPS catheter [9, 39]. Klinger et al. [40] analyzed the safety and benefit of transjugular thrombolysis with or without TIPS in 17 patients with noncirrhotic, nonmalignant portal vein thrombosis. The study could show a high recanalization rate of 94.1% with no major complications. The 1- and 2-year follow-up examination of these patients revealed portal vein patency rates of 88.2%. Transjugular thrombolysis with or without TIPS seems to be a safe and effective measure in acute, noncirrhotic, nonmalignant portal vein thrombosis. This is especially the case in patients presenting with bowel infarction and a low chance of revascularization with systemic anticoagulation, as was the case in our patient. A systematic review of the risks and benefit of thrombolysis and TIPS insertion in VITT-induced portal vein thrombosis is currently lacking, as there is only one other case documented so far, where TIPS insertion and thrombolysis was beneficial in the treatment of VITT [39]. Our patient is the first to be documented with VITT-induced atraumatic splenic rupture requiring splenectomy, TIPS insertion, and thrombolysis for successful management.


Vaccination with recombinant adenoviral vector vaccine can result in VITT, not rarely with a fatal course. Current treatment options include systemic anticoagulation avoiding heparin and the administration of IVIG, steroids, or other immunosuppressants and PLEX. In rare cases, fulminant and extended portomesenteric thrombosis additionally requires TIPS placement, local thrombaspiration, and lysis for successful management of VITT.
