Femoral arterial preclosure by purse-string suture for thoracic endovascular aortic repair / 中国胸心血管外科临床杂志

ABSTRACT

@#Objective    To evaluate the safety and efficacy of the femoral arterial preclosure by purse-string suture for thoracic endovascular aortic repair (TEVAR). Methods    From January 2013 to September 2016, TEVAR was performed on 40 patients with Standford type B aortic dissection. There were 34 males and 6 females aged 57.9±10.4 years. According to the surgical procedure, they were divided into a purse-string group (20 patients, 16 males, 4 females, aged 58.1±10.3 years), in which the patients received femoral arterial preclosure by purse-string suture and a convention group (20 patients, 18 males, 2 females, aged 57.7±10.8 years), in which the patients underwent conventional femoral cutdown. The outcomes and complications of two groups were evaluated. Results     There was no in-hospital death and no paraplegia event. There was significantly shorter operation time (70.4±24.0 min vs. 100.8±35.6 min, P=0.003) and less blood loss (39.5±29.8 ml vs. 83.5±86.5 ml, P=0.038) in the purse-string group than those in the convention group. Femoral artery stenosis was observed in 3 patients (15.0%) in the convention group and none in the purse-string group during the follow-up of 1-36 (17.2±11.5) months with no statistical difference (P=0.231). Conclusion    Using the femoral arterial preclosure by purse-string suture for TEVAR can save operation time, reduce intraoperative bleeding and decrease the approach-associated complications.
