Abstract：Objective To analyze the causes , prevention and treatment of the perioperative complications of Stanford B type dissection during endovascular treatment .Methods During July 2013 and November 2014 , statistical analysis of 52 cases of Stanford B type dissection with endovascular repair , and the causes , prevention and treatment of perioperative compli-cations were analyzed .Results 52 cases underwent the endovascular treatment and 54 coated stents were inserted .Preopera-tive complications occurred in 16 cases (30.8%).One case of lower extremity arterial embolization occurred before the stent placement with a stent graft and the first right lower limb artery was cut open and the thrombus was taken out .8 cases of im-mediate internal leakage occurred; through balloon expansion , increased support and attached with a force of blood vessel walls in 3 cases, 5 cases of close observation , and leakage disappeared in follow-up of 3-12 months.2 cases of intraoperative stent shift occurred and the proximal stent was added to ensure effective treatment .The 6-month follow-up did not show any shift and leakage .One stent strayed into the false lumen and was moved back to true lumen , through a big balloon expansion rupture in the bracket and the stent was also located in the true lumen for 10 d and 3 months postoperatively .On 30 d postop-erative, 2 cases of stroke occurred and after the symptomatic treatment , the patients were on their own in postoperative 3 months.Upper limb occurred in 2 cases but did not affect the quality of life and therefore no intervention was given .Conclu-sion The prevention and treatment of the preoperative complications of Stanford B type dissection during endovascular treat -ment should be emphasized .Further study of mechanisms of complications , interventional operational technology and the im-provement of medical equipment can help to reduce or avoid the incidence of preoperative complications .
