Lateral sacral veins

Gray586

The lateral sacral veins are a group of veins that accompany the lateral sacral arteries along the sides of the sacrum. These veins are part of the venous system and play a crucial role in draining blood from the sacral region.

Anatomy

The lateral sacral veins are typically two in number on each side of the sacrum. They run parallel to the lateral sacral arteries and are situated within the pelvic cavity. These veins collect blood from the sacral vertebrae, the sacral canal, and the surrounding muscles and tissues.

Function

The primary function of the lateral sacral veins is to drain deoxygenated blood from the sacral region and transport it back to the heart. They achieve this by emptying into the internal iliac veins, which then continue to the common iliac veins and eventually to the inferior vena cava.

Clinical Significance

The lateral sacral veins can be involved in various medical conditions, including pelvic congestion syndrome and deep vein thrombosis. Due to their location, they may also be at risk during surgical procedures involving the sacrum or the pelvic region.
