The short-term primary patency of endovascular intervention in recanalrization of chronic iliac arterial occluded diseases

SUMMARY:

Purpose: to evaluate the short-term primary patency of endovascular intervention in recanalrization of chronic iliac arterial occluded diseases.

Method and materials: prospective study, group of 21 patients with diagnosis of chronic occlusion of iliac arteries in Bach Mai hospital from 9/2011 to 6/2012. The patients were indicated to do revascularization by endovascular intervention.

Result: 21 patients with 28 iliac arteries which were treated by endovascular intervention including percutaneous angioplasty alone and Stenting. Arterial access were performed at common femoral arteries bilateral (retrograde) in 100%, including one failed case that required second intervention by brachial arterial access. No complication relates arterial access. There are 89,3% procedures of stenting with angioplasty post-Stenting and 100% completed deployment of stents. No complication of angioplasty and stent deployment such as arterial rupture or perforation. The success rate of recanalrization is 96% with 96% successful rate in the first approach to cross the over the occlusion. No required 2nd reintervention in duration of follow up from 1 to 6 months, 100% of case with improved intermittent claudication and ABI.

Conclusion: the initial results confirm that the endovascular intervention is a safe, effective method in the goal of recanalrization of chronic occluded iliac arteries.
