Anatomical variations; the origin of Profunda Femoris artery, its branches and diameter of the femoral artery.
Professional Med J Jan ;14(3):523-7.

Profunda femoris artery and its circumflex branches are encountered during cannulation of femoral artery for various clinical and diagnostic techniques. Objectives: To study the variations in the origin of the profunda femoris artery and its circumflex branches along with measurement of internal diameter of femoral artery. Design: Cadaveric studies. Setting: Anatomy Departments of Fatima Jinnah Medical College and Services Institute of Medical Sciences, Lahore. Period: From 04-08-06 to 30-06-07. Material Methods: In 20 adult male cadavers, 40 femoral triangles were dissected and femoral artery, profunda femoris artery and its branches were exposed. The distance of origin of the profunda femoris artery from the mid point of inguinal ligament and the origin of the circumflex arteries from the profunda femoris were measured by a scale and radial caliper. The internal diameter of femoral artery was recorded with radial caliper after injecting it with gelatin and undiluted Indian ink. Results: In 12 to 14 cases the origin of the profunda femoris artery was located between 20-40 mm from mid point of the inguinal ligament. In 6-8 cases profunda femoris originated lower down in the thigh than the common location. Only in one case the medial circumflex artery was seen emerging from the femoral artery at the level of origin of profunda femoris artery. In one case lateral circumflex artery originated directly from the femoral artery unilaterally. The internal diameter of the femoral artery ranged between 6-10 mm.
