Superficial Iliac Circumflex Artery, Anterior View

Description

Running anterolaterally from the femoral artery just inferior to the inguinal ligament, the superficial iliac circumflex artery curves toward the anterior superior iliac spine and courses parallel to the ligament before breaking into small superficial branches in the lower abdominal wall. Medial to it, the external iliac artery transitions beneath the inguinal ligament to become the femoral artery in the femoral triangle, with the femoral vein lying medial and slightly posterior to the artery. Bony landmarks of the anterior pelvis frame the field, including the iliac crest and the superior pubic region, while fine arteriolar and capillary networks fill the superficial fascia over the proximal thigh and groin. Small vessels, clear relationships. This anterior perspective matters when planning groin access and incisions because the superficial iliac circumflex artery is a predictable source of troublesome bleeding during open inguinal hernia repair, lymph node biopsy, or creation of a groin incision for vascular exposure. Its proximity to the inguinal ligament and anterior superior iliac spine also makes it relevant when raising superficial flaps from the lower abdominal wall and when interpreting superficial postoperative hematomas after femoral arterial puncture or closure device placement. Understanding its relationship to the femoral neurovascular bundle helps you stay out of the wrong plane. Use this artwork to teach the femoral triangle and superficial groin vasculature in gross anatomy, surgical anatomy, and interventional radiology courses, or to illustrate operative technique discussions in hernia, plastic, and vascular surgery publications focusing on inguinal approaches and flap planning.
