Compression on iliac vein from distended urinary bladder

Abstract

Compression on iliac veins by distended urinary bladder is not frequently reported in the currently available English literature. This predominantly affects men, who are vulnerable to prostatism. Here, we report one female case of iliac vein compression caused by distended urinary bladder because of neurogenic bladder after radical hysterectomy for cervical cancer. A 49-year-old female patient with type-2 diabetes mellitus, obesity, and a history of cervical cancer was treated by radical hysterectomy in her 20s. Swelling and pain of bilateral lower extremities gradually progressed within 3 days and persisted for a few months before her admission to our hospital. Her illness was previously diagnosed as MayThurner syndrome according to findings of computed tomography (CT) with intravenous contrast of the pelvis and received balloon angioplasty. We arranged intravenous digital subtraction venography and CT venography to evaluate her iliac veins and inferior vena cava. Smooth indentation and stenosis at the left common iliac vein and by the right common iliac artery, with regurgitation of contrast into the internal iliac vein and engorged presacral venous plexus supported the diagnosis of May-Thurner syndrome.
