Surgical Significance of Tibioperoneal Trunk in Lower Limb Revascularization Procedures

Abstract

Background: Popliteal artery is a continuation of femoral artery, which extends obliquely from the osseoaponeurotic opening of adductor magnus to lower border of popliteus muscle, where it terminates by dividing into anterior tibial artery and tibioperoneal trunk, this ranges from 92% to 96%. Knowledge of anatomic variability in this region may have clinical implications and are very essential during vascular grafting, direct surgical repair, transluminal angioplasty, embolectomy, and other arterial injury. Materials and Methods: This study was conducted in anatomy department where 50 lower limbs embalmed with 10% of formalin will be procured from the department. Artery and its branches were exposed. Side determination, branching pattern of terminal branches will be noted, and measurements of the length of tibioperoneal trunk will be taken with the help of digital micrometer. Results: Length of tibioperoneal trunk was taken with the help of digital Vernier caliper. All data obtained will be produced in tabulated form and if any variations was photographed. Conclusions: Proper characterization of the anatomical properties of popliteal artery requires adequate knowledge of its terminal branching variants. Increasing rates of surgical reconstructions and vascular surgical procedures of the lower extremity place more significance on having detailed anatomical information. Endovascular treatment of critical limb ischemia in diabetics with crural and pedal diseases can be an exceedingly challenging and complex problem, in this regard prior awareness of variant branching pattern of terminal end of popliteal artery is important for planning appropriate surgery and to reduce arterial injury.
