摘　　要：目的：探讨“象鼻”技术的手术适应证、手术方法及围术期脑和脊髓的保护措施。方法：经右锁骨下动脉选择性脑灌注．在一期手术行升主动脉和主动脉弓替换的同时，将一段人工血管（即“象鼻”）漂浮于降主动脉中，为二期手术做准备。结果：2例患者一期手术顺利，超高速计算机断层摄影术均示一期治愈，无需二期手术。结论：“象鼻”技术是一种分期治疗广泛主动脉病变的手术方法。Objective: To discuss the indications, operative methods and perioperative trealtnents for preventing from neurologiccomplications of the 'elephant trunk technique'.Methods:Two patients of DeBakey type I aortic dissection were operated with selective cerebral perfusion via rightsubclavian artery. At the first stage of operation,a dangling aortic prosthesis ('elephant trunk')was inserted into the distalaorta while replacing the ascending aorta and aortic arch for the next procedure.Results: Two operations were successful. UFCT showed that the two patients were cured after the first stage of operation,and the second procedure would be avoided.Conclusion:The 'elephant trunk technique' maybe in need of several procedures for the treatment of extensive(ascending,aortic arch and descending parts)aneurysmal diseases of the aorta. It can also be used for Patients with aortic dissectinganeurysm of DeBakey type 1. Some patients are cured after the first stage of operation.
