Abstract:
:The anatomic variation in the branching pattern of the popliteal vessel has been well-established. Little has been written in the literature regarding recipient vessel selection for microvascular reconstruction in the lower extremity as it pertains to aberrant vascular anatomy. We present the case of a 57-year-old male patient who sustained a closed right lower extremity pilon fracture in a motor vehicle accident. The patient was initially treated with external fixation, which was followed by definitive open reduction and internal fixation 3 weeks later. Over the next 2 weeks, the patient developed skin ischemia of the anterior ankle. A free-tissue transfer was planned. A digital subtraction angiogram revealed absence of the posterior tibial (PT) vessels and an aberrant course of the peroneal (PR) artery. In the operating room, the medial distal leg was explored for the PT vessels, which were severely hypoplastic. Given the close proximity of the PR vessels, the dissection was extended proximally to assess these vessels for microvascular anastomosis. They were found to be suitable. A parascapular flap was harvested and transferred to the right leg wound without any significant stretch on the vessels for soft tissue coverage. The flap demonstrated excellent inflow and outflow, and the leg and foot remained well perfused. The patient's postoperative course was uncomplicated. The technique of exposing the peroneal vessels for microvascular anastomosis via a medial approach is described. This technique is an excellent option to have available when aberrant anatomy precludes the use more commonly utilized vessels.
