Abstract

Introduction: The anatomical knowledge of variations of femoral artery and its branches is important as it is frequently accessed by surgeons and radiologists for number of procedures. Profunda femoris artery is the largest branch of femoral artery, it is chief supply of the thigh. It is frequently incorporated in vascular reconstructive procedures in the proximal leg. Femoral artery is frequently accessed by radiologists for number of procedures, and surgeons. Accurate knowledge of anatomical variations of femoral artery and its branches including profunda femoris, medial and lateral femoral circumflex arteries is required to minimize complications and hence it is suggested for the clinicians planning surgery and intervention. Materials and Methods: In the present study, dissection was performed on 70 lower extremities of 35 embalmed cadavers in the department of Anatomy, Yenepoya Medical College Mangalore. The distance of the site of origin of profunda femoris artery from the midpoint of the inguinal ligament was measured in mm with a scale and recorded. The site of origin of medial and lateral circumflex femoral arteries were studied. Results: In present study of profunda femoris artery, we found posterolateral and lateral aspect of origin was common (72.85%) than posterior and posteromedial aspect of origin (19.83%). In three limbs (3.03%) profunda femoris artery was originating from medial side of femoral artery and it coursed superficial to femoral vein. As per various literatures this is rare. The site of origin of profunda femoris artery was between 21-40 mm on 48 limbs. In 12 limbs we found high origin of profunda femoris artery (distance < 10mm). In 10% cases profunda femoris artery took origin as a common stem of femoral artery, that is origin of profunda femoris and two circumflex arteries from single site. Conclusion: Anatomical knowledge of branching pattern of femoral and profunda femoral artery and their distance of origin is very important to surgeons to avoid inadvertent damage to these vessels and to avoid complications during surgeries. the complications in vascular reconstructive surgeries.
