Treatment for arteriosclerosis obliterans complicated with acute thrombosis of lower extremity / 中华普通外科杂志

ABSTRACT

Objective:To discuss the clinical treatment for arteriosclerosis obliterans combined with acute thrombosis (ASOCAT) of lower extremities.Methods:The treatment methods and results of 30 patients with ASOCAT admitted to our center from Jan 2009 to May 2019 were retrospectively analyzed.Results:The course of acute thrombosis in 30 patients was (9.5±5.2) days, and the average course of ASO was (2.1±1.4) years. Among 30 patients, 13 patients had aortoiliac occlusion (type Ⅰ), and 17 patients had femoropopliteal lesion (type Ⅱ). Twenty-eight patients underwent endovascular treatment, 1 had hybrid operation, and 1 was given aorto-bilateral femoral bypass. One patient died perioperatively. 24 patients were followed up for (16.3±16.1) months. One died during follow-up.Two patients underwent above-knee amputation within 6 months. Two patients had distal superficial femoral artery reocclusion within 12 months. The restenosis/reocclusion rates within 12 months of type Ⅰ and Ⅱ patients were 12.5% and 21.4%, respectively. The 6/12-month amputation-free survival rates for type Ⅰ and type Ⅱ were 87.5%/87.5% and 92.8%/85.7%, respectively.Conclusion:Reasonable and active use of open surgery, endovascular treatment or hybrid operation could achieve acceptable outcomes in patients with ASOCAT.
