Endovascular Management on a May-Thurner Syndrome Patients with Iliac Vein Thrombosis

ABSTRACT

PURPOSE: We wanted to evaluate the effectiveness of endovascular management for treating patients suffering with May-Thurner syndrome along with left iliac vein thrombosis. METHODS: 11 patients with May-Thurner syndrome underwent treatment from January 2002 to December 2004. We evaluated the symptoms, diagnostic modalities, involved sites, treatment modalities, volume of the thrombolytic agent (urokinase), types of stent, complications and outcomes for each of the patients. RESULTS: The 11 patients were 54+/-15 years old and the male to female ratio was 1 2.66. Combined endovascular management was used for all patients. They were diagnosed by radioisotope scan, computed tomographic angiography, color doppler image and conventional venography. Endovascular procedures such as stent insertion, catheter-directed thrombolysis using urokinase infusion, balloon angioplasty and aspirated thrombectomy were used as treatment modalities. We placed the stents into the involved veins in 11 patients. Technical success was achieved in 10 out of 11 patients. Ten patients experienced a successful clinical outcome without any recurrence or complication during the follow-up periods. CONCLUSION: Endovascular management such as stent placement is an effective method for restoring venous patency and it provides relief of the acute symptoms.
