Superficial circumflex iliac artery

Superficial Circumflex Iliac Artery

The superficial circumflex iliac artery and its branches.

The Superficial Circumflex Iliac Artery (SCIA) is a small artery in the human anatomy that arises from the femoral artery near the inguinal ligament. It is responsible for supplying blood to the lower abdominal wall and the upper part of the thigh.

Structure

The SCIA originates from the lateral side of the femoral artery, just below the inguinal ligament. It then courses laterally, running parallel to the ligament, and gives off several branches that supply the skin and muscles of the lower abdomen and upper thigh.

Function

The primary function of the SCIA is to supply blood to the skin and muscles of the lower abdomen and upper thigh. It also plays a role in the vascularization of the inguinal lymph nodes.

Clinical significance

Due to its location and size, the SCIA is rarely involved in significant vascular disease. However, it can be affected by trauma or surgery in the inguinal region, and its damage can lead to complications such as hematoma or ischemia.
