E-Mail: [email protected] Introduction & aim: Anatomical variations in the arterial system are very common. In spite of advanced invasive techniques, knowledge of variations still remains limited. One such artery showing variations is the popliteal artery. Limb-threatening sequelae ensue from its damage. The aim of the study encompasses gaining knowledge on the anatomy of Popliteal artery with respect to its commencement, termination, branching pattern & its relation with surrounding structures mainly the muscles in the Popliteal fossa with a view of helping surgeons from various fields while performing surgery in this region. Comparison with results from previous studies on the popliteal artery was also planned. Materials and Methods: The study was carried out in 50 lower limbs of 25 well embalmed cadavers of South Indian origin irrespective of age and sex. None of the limbs showed any evidence of previous knee surgery. Results: Popliteal artery was the continuation of femoral artery. The level of termination in relation to the Popliteus muscle was high in one case and in the middle in another case. Popliteal artery terminated into anterior tibial and posterior tibial arteries. Arterial trifurcation was unobserved. Course was found to be normal with the Popliteal vein and Tibial nerve lying lateral to the artery in the upper part of popliteal fossa and medial to it in the lower part by crossing superficial to it. Third head of Gastrocnemius or aberrant band was not found. Conclusion: This study provides information vital to the successful accomplishment of surgical, radiological or interventional procedures to be carried out in the vicinity of the vessel.
