Table 1 Kim–Lippert classification of the infrapopliteal arterial branching variations

From: Free gracilis end-to-side microanastomosis to a peronea arteria magna: a case report

Type I

Normal level of branching (proximal to the lower border of the popliteus muscle)

  IA

The PA divides into the AT, the TPT (later divides into PT and PR)

  IB

The PA trifurcates into AT, PT, and PR

  IC

The PA divides into the PT, the anterior TPT (later divides into AT and PR)

Type II

High division of the PA (at or above the knee joint)

  IIA

The AT originates at or above the knee joint

  IIB

The PT originates at or above the knee joint

  IIC

The PR originates at or above the knee joint

Type III

Hypoplastic or aplastic branching with altered distal supply.

  IIIA

Hypoplastic/aplastic PT

  IIIB

Hypoplastic/aplastic AT

  IIIC

Both tibial arteries are hypoplastic/aplastic (PAM)
