Abstract
The medial circumflex femoral artery usually arises from the deep femoral artery. It supplies the supplies adductors and hamstring group as well as sciatic nerve and femoral head and neck through anastomosis. In current study includes 342 dissected hemipelvis to clarify the origin of medial circumflex femoral artery. The medial circumflex femoral artery arose from the common and deep femoral artery in 39.3% and 57%. Infrequently, it arose from the superficial femoral artery in 2.5% whereas it arose from the lateral circumflex femoral artery in 0.6%. In contrast, it found to be congenital absent in 0.6%. In current study, the usual origin level of medial circumflex femoral artery found to be proximal to lateral circumflex femoral artery in 52% and distal to the deep femoral artery in 57.3%. Knowing the medial circumflex femoral artery limits avascular necrosis of the femoral head such as embolization procedure. Therefore, knowing the origin variability of the medial circumflex femoral artery may lead to avoid iatrogenic fault in several procedures such as arterial bypass procedure to protect vascular supply of lower limb. Radiologists as well as orthopedics and vascular surgeons have to be aware of the medial circumflex femoral artery variation.
Highlights
The medial circumflex femoral artery arises from medial or posterior aspect of the deep femoral artery (Carter 1867; Sharpey et al 1867)
The medial circumflex femoral artery terminates into two branches are ascending and descending (Carter 1867), anterior and posterior (Sharpey et al 1867), muscular and articular (Wilson 1868), and superficial and deep (Standring 2005)
The current study targets the origin of medial circumflex femoral artery and its level
Summary
The medial circumflex femoral artery arises from medial or posterior aspect of the deep femoral artery (Carter 1867; Sharpey et al 1867) It was known as circumflexa femoris interna (Wilson 1868) or arteriae circumflexae femoris medialis. Medial circumflex femoral artery supplies adductors, gracillis, obturator externus and hamstring muscle (Carter 1867; Sharpey et al 1867; Wilson 1868). It supplies the sciatic nerve (Georgakis 2008) It anastomoses with the inferior gluteal, lateral circumflex. With a good background of the anatomical characteristics of medial circumflex femoral artery, it may reflect a clinical important in radiology, vascular surgery and orthopedic fields to minimize the postsurgical complications
