Objective To analyze the reasons for the perioperative death of endovascular repair of acute aortic dissection （AD）. Methods The clinical data of 176 patients with acute AD and received endovascular repair from July 2001 to October 2012 were analyzed retrospectively. Results Among 176 patients with acute AD， 8 patients died during perioperatively， received endovascular repair in 1-5 days after admission （mean 2.4 d）， and all of them admitted before 2008. Two cases were type A and 6 cases were type B. All cases with hypertension and 3 cases with pleural effusion. Three cases died on the day of operation， among them 2 cases occurred in 1 h after operation， the other 1 case occurred in 2 h after operation. Four cases died in 2 days after operation and 1 case died in 4 days after operation. Four cases died of rupture of the aortic dissection， 2 cases died of cerebral infarction， 1 case died of multiple organ failure， and 1 case died of gastrointestinal bleeding. Conclusion To avoid performing endovascular repair during the acute phase and improving operation skills may help to avoid the occurrence of perioperative death.
Objective To explore the clinical experience of endovascular treatment for arteriosclerosis obliterans (ASO) of lower extremities. Methods Endovascular treatment were performed on 22 patients (26 limbs) suffering from ASO which were diagnosed by magnetic resonance angiography (MRA). The clinical efficacy after operation was analyzed. Results Twentytwo lower extremities of 18 patients successfully accepted endovascular treatment with 12 stents planted without major complications. Four cases failed to endovascular treatment and 2 of them converted to bypass surgery. The clinical symptoms of limb ischemia vanished or significantly improved after treatment. The ankle brachial index (ABI) of affected extremities increased from 0.35±0.13 (before operation) to 0.70±0.15 (after operation), Plt;0.01. During the follow-up of 2-18 months, 3 cases suffered re-occlusion of artery of lower extremity, in them one case received drug treatment and 2 cases resolved by percutaneous transluminal angioplasty (PTA) and stenting again. Conclusion Endovascular treatment for ASO of lower extremities has such advantages as minimal invasiveness, reduced complications and repeatability. It may serve as a more promising choice of method to clinical treatment of ASO.
目的 分析股动静脉插管在体外膜肺氧合（extracorporeal membrane oxygenation，ECMO）抢救治疗中的临床应用。方法 回顾性分析笔者所在医院2002 年6 月至2010年7 月期间因重症心肺功能衰竭而施行股动静脉插管并进行静脉-动脉转流体外膜肺氧合（VA-ECMO）抢救的47例患者的临床资料。结果 本组47例患者均顺利施行ECMO支持，37例患者经过治疗后治愈出院，10例死亡。插管并发症有出血、肢体缺血等，均经相应处理后治愈。结论 ECMO对急性心肺衰竭是理想的支持方法，股动静脉为急救插管的首选通道。
Objective To evaluate the clinical efficacy of t ransplantation of autologous peripheral blood stemcells ( PBSC) for the t reatment of lower limb arterial ischemic disease. Methods From March 2004 to February2007 , 16 patient s with severe lower limb arterial ischemic disease were t reated with autologous PBSC t ransplantation. Recombinated granulocytecolony stimulating factor ( G2CSF) was used to mobilize the proliferation of bonemarrow stem cells and then the stem cells were released into peripheral blood. Af ter 5 - 6 days , PBSC were collected by CS23000 PLUS blood2cells separator. Such concent rated stem cells fluid was int ramuscularly injected into theischemic areas of the lower limbs. Results The result s of 3 to 242month following2up after the t ransplantation ofstem cells showed that the resting pains of the affected limb were greatly relieved , and ulcers were healed. The distance and duration of intermittent limping became farther and longer. Conclusion Transplantation of autologousPBSC would be a novel and effective method for the t reatment of arterial ischemic disease. However , this method isstill at the stage of initial clinical application , so it still need to be further studied.
