Because of its similarities to deep vein thrombosis (DVT), May–Thurner syndrome is rarely diagnosed amongst the general population. In this condition, the right iliac artery sequesters and compresses the left common iliac vein against the lumbar section of the spine, [5] resulting in swelling of the legs and ankles, pain, tingling, and/or numbness in the legs and feet. [6]
Both common iliac arteries are accompanied along their course by the two common iliac veins, which lie posteriorly and to the right. Their terminal bifurcation is crossed anteriorly by the ureters. [1] This is significant, as the bifurcation of the common iliac artery is the second point of ureteric constriction. [1]
Angiography provides important information regarding the perfusion and patency of distal arteries (e.g. femoral artery). The presence of collateral arteries in the pelvic and groin area is important in maintaining crucial blood flow and lower limb viability. However, angiography should only be used if symptoms warrant surgical intervention. [2]
The right common iliac artery passes in front of the left common iliac vein. In some individuals, mainly women with lumbar lordosis , this vein can be compressed between the vertebra and the artery. This is the so-called Cockett syndrome or May–Thurner syndrome [ 2 ] can cause a slower venous flow and the possibility of deep venous thrombosis ...
Arterial occlusion can be classified into three types based on etiology: embolism, thrombosis, and atherosclerosis. These three types of occlusion underlie various common conditions, including coronary artery disease, [4] peripheral artery disease, [5] and pulmonary embolism, [6] which may be prevented by
In human anatomy, the iliac arteries are three arteries located in the region of the ilium in the pelvis: . Common iliac artery – forms at terminus of the aorta; External iliac artery – forms where the common iliac artery bifurcates, continues as the femoral artery at the inguinal ligament
Upper extremity PCD is less common, occurring in under 10% of all cases. [1] PCD results from extensive thrombotic occlusion (blockage by a thrombus) of extremity veins, most commonly an iliofemoral DVT, of the iliac vein and/or common femoral vein. [2] [3] It is a medical emergency requiring immediate evaluation and treatment.
