Abstract:
Objective To present clinical results of endovascular treatment of total iliac vein occlusions and to discuss the technique details of this treatment. Methods From Feb 2006 to Aug 2010,15 patients with chronic total occlusive lesions of the iliac vein and adjacent vein segments underwent endovascular treatment. Average age was (62 ±7) years (range 35 to 81 years), the male/female ratio was 12: 3. Clinical score of CEAP was grade 3 in 33. 3%, grade 4 in 40%, grade 5 in 13. 3%, and grade 6 in 13.3%. Venography showed left iliac vein was occluded in all 15 patients, common femoral vein was occluded in 14 patients, and superior femoral vein was occluded in 9 patients, however profounder femoral vein was patent in these patients with superior femoral vein being occluded. Results No postoperative major morbidity or mortality was seen. The technique success rate was 93. 3%. Treatment failure was caused in one case for a wrong selection of the femoral vein approach site. The average length of stent was 18. 4 cm.In 12(80. 0% ) stents crossed the inguinal ligament. The average follow-up time was 11.6 ± 2. 4 months.The primary patency rates of the stents at 6 months were 92. 9%. 10 (66. 7% ) patients were asympotomatic, 3(20% )were improved, 1 (6. 7% ) was unchanged, and 1 (6.7%) was worse, compared to before intervention. Conclusions Endovscular recanalization and stent placement is a safe and effective treatment for chronic total occluded iliac veins, with good patency, significant symptom resolution, and minimal morbidity in the short term follow-up.
