Insights
May-Thurner syndrome, a cause of deep vein thrombosis, requires prompt diagnosis. This case highlights a rare venous stenting complication and the importance of intravascular ultrasound for successful treatment.
Area of Science:
- Vascular Surgery
- Interventional Radiology
Background:
- May-Thurner syndrome involves left common iliac vein compression, increasing deep vein thrombosis risk.
- It often presents as chronic venous disease in young adults.
Background:
May-Thurner syndrome results from chronic compression of the left common iliac vein between the right common iliac artery and the lumbar vertebrae. It predisposes to iliofemoral deep-vein thrombosis.
Case Summary:
A 40-year-old man presented with recurrent ulceration of the left medial gaiter region. Computed tomography venography revealed compression of the left common iliac vein. Endovascular therapy was performed and a dedicated venous stent was deployed. Postdilatation of the stent resulted in fracture of the stent at the compression point. Rescue was achieved by deploying an overlapping venous stent, restoring circular luminal geometry. The patient experienced symptomatic improvement, and the venous ulcer resolved within 5 months.
Discussion:
This report illustrates a rare complication of venous stenting and emphasizes the critical role of intravascular ultrasound in recognizing device failure and guiding immediate corrective intervention.
Take-Home Messages:
May-Thurner syndrome should be suspected in young patients with severe unilateral chronic venous disease. Fracture of venous stents may occur at the iliac compression site after deployment.
