About

Iliac vein blockage occurs when the major veins draining the pelvis become obstructed, disrupting blood flow. Symptoms may include leg swelling, pain, or skin discoloration. Treatment options include anticoagulation, venous stenting, or surgical bypass, tailored to the specific cause and severity of the blockage.

‍

Symptoms

Symptoms of iliac vein blockage may include leg swelling, pain, or heaviness, particularly with standing or walking. Some individuals may notice skin changes such as redness or discoloration, or develop ulcers. Seeking medical evaluation promptly is important to prevent complications such as deep vein thrombosis or venous insufficiency.

‍

Treatments

Treatment of iliac vein blockage aims to restore venous blood flow and alleviate symptoms. Depending on the underlying cause and severity, options may include anticoagulation therapy, venous angioplasty with or without stent placement to reopen the blocked vein, or surgical intervention such as venous bypass. Individualized management plans are tailored to each patient's specific condition and needs for optimal outcomes.

‍

Studies Performed

Studies performed to diagnose iliac vein blockages include duplex ultrasound, which assesses blood flow and detects abnormalities in the veins. Computed tomography angiography (CTA) and magnetic resonance angiography (MRA) provide detailed images of the iliac veins, aiding in diagnosis and treatment planning. These tests help identify blockages and assess their severity.

Prevention

Preventing iliac vein blockage involves managing risk factors such as deep vein thrombosis, pelvic trauma, and compression from neighboring structures. Regular physical activity, maintaining a healthy weight, and avoiding prolonged sitting or standing are crucial. Routine medical check-ups to monitor venous health and early intervention for any symptoms or abnormalities contribute to prevention.
