Abstract

The fibular artery originates distal to the popliteus muscle and descends along the inferior tibiofibular syndesmosis. A key feature of this artery is its primary perforating branch. Knowledge of the anatomy and variations of this branch is essential for surgeons to achieve optimal surgical outcomes. Variations in the posterior tibial artery (PTA) and fibular artery (FA) are frequently seen in cadaveric dissections and imaging studies. These variations are important for evaluating arteriograms and performing procedures such as vascular grafting, angioplasty, and embolectomy. Our study found that the fibular artery pierced the interosseous membrane 8 cm proximal to the lateral malleolus, continuing as the dorsalis pedis artery. Recognizing these variants is crucial for assessing peripheral arterial disease and planning revascularization.
