External Iliac Artery Occlusion

External Iliac Artery Occlusion occurs when the blood flow through the external iliac artery is blocked or restricted. This condition can lead to various symptoms and complications, requiring prompt diagnosis and appropriate treatment. Let’s delve into the details of this medical condition in simple language to enhance understanding.

The external iliac artery is a crucial blood vessel in the pelvic region, supplying blood to the lower limbs. When this artery gets blocked, it can result in External Iliac Artery Occlusion.
