Endovascular treatment of Leriche syndrome: analysis of curative effect / 介入放射学杂志

ABSTRACT

Objective To evaluate the curative effect of endovascular treatment for Leriche syndrome.Methods The clinical data of 57 patients with Leriche syndrome,who were admitted to authors' hospital during the period from September 2010 to October 2014,were retrospectively analyzed.The curative effect of percutaneous transluminal angioplasty (PTA) was analyzed.Results Among the 57 patients (65 diseased limbs in total),simple PTA was employed in 2,catheter directed thrombolysis (CDT) with subsequent PTA and stenting in 5,and PTA plus stenting in 50.A total of 97 stents were implanted,the technical success rate was 100％.After the treatment,the ankle brachial index (ABI) increased from preoperative (0.42±0.22) to postoperative (0.83±0.15),the difference between the two data was statistically significant (P＜0.01).Thepatients were followed up for (9.8±2.8) months.The 6-month and 12-month primary patency rates were 95.4％ and 90.7％ respectively,the postoperative secondary patency rate was 96.4％.After the treatment,the symptoms of lower limb ischemia were improved in all patients.During perioperative period,iliac artery rupture due to balloon dilatation occurred in 2 patients,pseudoaneurysm at brachial aaery puncture point in one patient,hematoma at puncture point in 3 patients,cerebral infarction in 2 patients and myocardial infarction in one patient.One patient developed contrast-induced nephropathy and finally died of multiple organ dysfunction syndrome.The perioperative mortality was 1.75％.One patient developed in-stent obstruction in 3 months after two stage treatment,and artificial vascular bypass grafting had to be carried out.Conclusion For the treatment of Leriche syndrome,PTA is safe and reliable,it carries less complications and lower perioperative mortality with satisfactory short-term patency rate.(J Intervent Radiol,2017,26221-224)
