lateral femoral circumflex vein

The lateral femoral circumflex vein is a vein that drains blood from the front and middle areas of the thigh and empties into the femoral vein as one of its tributaries.

The lateral femoral circumflex vein is located in the upper thigh, accompanying the lateral femoral circumflex artery around the lateral aspect of the femoral neck before joining the femoral vein in the femoral triangle.

The lateral femoral circumflex vein is involved in collecting and returning deoxygenated blood from the anterior and middle compartments of the thigh, including muscles such as the quadriceps, to the femoral venous system.

Femoral vein thrombosis, hip or thigh surgery complications, femoral neck fractures, or vascular anomalies of the proximal thigh may be associated with the lateral femoral circumflex vein.

The lateral femoral circumflex vein may be assessed through Doppler ultrasound of the thigh veins, CT or MRI angiography of the hip and proximal thigh, or during surgical procedures in the femoral triangle region.
