Pseudoaneurysm in posterior tibial artery: A rare complication in fracture tibia fibula treated with fasciotomy and external fixator

Abstract

A case of post-traumatic posterior tibial artery pseudoaneurysm following a fractured tibia and fibula with acute compartment syndrome was treated with fasciotomy and external fixator in 17-year-old female. She was investigated for gradual onset boggy swelling after 7 weeks after the initial injury and fixation and diagnosed with an aneurysm at lower limb CT angiography contrast leakage was noticed radiologically (Fig 4). This rare complication of fracture tibia and fibula has to be considered in patient presenting boggy gradual swelling treated with external fixator application following the safe zone of pin insertion proximally.
