The Significance of Medial Sural Artery Integrity in Popliteal Artery Trauma: A Case Report

Abstract

Two patients with popliteal artery trauma who underwent secondary amputations due to refractory calf sepsis despite a patent arterial repair are presented in this case report. The medial sural artery, the main arterial supply of the medial head of the gastrocnemius, was surgically severed in both patients owing to the use of a continuous medial incision from the supra level to infragenicular level. The compromised arterial supply of the medial head of the gastrocnemius muscle may have contributed to the devitalization of the muscle and the subsequent calf sepsis, and it is speculated that this was related to the unfavorable outcome.
