目的分析冠状动脉支架植入术后Stanford A型主动脉夹层患者的外科治疗方式,探讨其手术技术及手术时机。方法回顾性分析2016年4月—2019年7月首都医科大学附属北京安贞医院连续收治的1246例Stanford A型主动脉夹层患者的临床资料。纳入冠状动脉支架植入术后Stanford A型主动脉夹层患者。结果最终纳入患者19例,其中男16例、女3例,年龄35~66(54±7)岁。19例患者中急性主动脉夹层11例。AC型(DeBakeyⅠ型)主动脉夹层15例,AS型(DeBakeyⅡ型)4例。AC型患者中行孙氏手术(全弓置换+支架象鼻手术)10例,部分弓置换5例;19例患者中同期行冠状动脉旁路移植术7例,二尖瓣置换术1例;4例患者术中取出位于右冠开口的支架。本组住院死亡1例,主因术前合并脏器灌注不良,术后死于多脏器功能衰竭。18例患者经治疗后痊愈出院,平均随访30(18~56)个月,其中1例因冠状动脉吻合口漏行二次漏修补术,1例因远端夹层新发破口行胸主动脉腔内修复,1例因左主干支架闭塞急诊行经皮冠状动脉介入治疗,1例因髂动脉闭塞行股股转流。结论冠状动脉支架植入术后Stanford A型主动脉夹层的患者中,医源性主动脉夹层同期行冠状动脉旁路移植的比例高,对于广泛受累的Stanford A型主动脉夹层应当积极手术治疗。

The high content of aluminum(Al)impurity in the recycled cathode powder seriously affects the extraction efficiency of Nickel,Cobalt,Manganese,and lithium resources and the actual commercial value of recycled materials,so Al removal is crucially important to conform to the industrial standard of spent li-ion battery cathode *** this work,we systematically investigated the leaching process and optimum conditions associated with Al removal from the cathode powder materials collected in a wet cathode-powder peeling and recycling production line of spent li-ion batteries(liBs).Moreover,we specifically studied the leaching of fluorine(F)synergistically happened along with the removal process of Al,which was not concerned about in other studies,but one of the key factors affecting pollution prevention in the recovery *** mechanism of the whole process including the leaching of Al and F from the cathode powder was indicated by using NMR,FTIR,and XPS,and a defluoridation process was preliminarily investigated in this *** leaching kinetics of Al could be successfully described by the shrinking core model,controlled by the diffusion process and the activation energy was 11.14 kJ/***,the leaching of F was attributed to the dissolution of liPF6and decomposition of PVDF,and the kinetics associated was described by Avrami *** interaction of Al and F is advantageous to realize the defluoridation to some *** is expected that our investigation will provide theoretical support for the large-scale recycling of spent liBs.
