Endovascular Treatment Endovascular Treatment of Superficial Femoral Artery Lesions: Balloon versus Stent Angioplasty
Percutaneous transluminal angioplasty and stent deploying are the most commonly performed therapeutic interventions for chronic limb ischemia. These are relatively inexpensive, easily performed, and associated with fewer complications.
Objectives: To assess the epidemiology of superficial femoral artery disease and to compare the endovascular treatment patency rate by balloon and stent.
Methods: In this prospective randomized comparative study, sixty patients were candidates for interventional angiography at Ghazi – Al hariri surgical subspecialties hospital in Bagdad, Iraq from the 1 st of October 2015 to the 30th of December 2015. They were followed for six months. We classified the patients into two groups (group 1 balloon 32 patients and group 2 stent 28 patients). We compared between them according to age, gender, side of lesion, presenting symptoms, duration, risk factors, associated affected arteries, site of stenotic lesions, means of stenosis by duplex preoperatively, during angiography and postoperatively by duplex at 1st ,3rd and 6th months also by means of lesion lengths, complications and mortality rate.
Results: The most common age group was (60 – 69) years with 27 patients (45%) in both groups. The male gender was 44 patients (73.4%). The left lower limb was mostly affected and operated in 34 patients (56.7%). Most patients present with claudication (38 patients). The mean of stenosis percentage picked up by preoperative angiography was slightly higher than that watched by duplex study (70-85% by angiography to 70-75% by duplex). The mean of restenosis percentage for balloon, stent groups were up to (31.25%), (3.57%), respectively, at 6 th month postoperatively. One patient with mild extravasation in balloon group was occurred during the procedure and one patient only with recurrent thrombosis was picked up in 1st month of follow up in stent group.
Conclusion: The stent deploying has more patency and less residual stenosis than percutaneous transluminal angioplasty alone.
