急性主动脉夹层动脉瘤行全弓置换术后并发症的处理

目的 总结34例急性Stanford A型主动脉夹层动脉瘤行全弓置换术后并发症的发生及处理经验.方法 2005年1月至2010年10月,我院共为34例急性Stanford A型主动脉夹层动脉瘤的患者行全弓置换手术治疗,其中男28例,女6例；年龄34.0～ 60.0岁.发病至入院的时间为4～18h.术前超声检查发现合并主动脉瓣关闭不全8例,二尖瓣关闭不全1例.结果 全组术后死亡3例,病死率8.8％.术后发生严重并发症包括急性肾功能损伤13例,呼吸功能不全12例,截瘫l例,精神障碍10例,术后出血再次手术止血2例.结论 急性Stanford A型主动脉夹层动脉瘤的患者行全弓置换手术后各种并发症的发生率较高而且严重.对行全弓置换手术的患者,应加强围术期的监护,针对可能出现的各种并发症做出早期诊断和及早处理.

The treatment of post-operative complications after total arch reolacement for acute tvoe a aortic dissection

Objective To describe the treatment experience of post-operative complications after total arch replacement for acute type A aortic dissection in 34 cases.Methods The subjects were 34 consecutive patients (Twenty-eight males and 6 females,age 34.0 -60.0 yrs) who received total arch replacement for acute Stanford type A aortic dissection from Jan.2005 to Oct.2010 in our hospital.The duration from the onset of the symptoms to the hospitalization ranged from 4 - 18 hrs.Pre-operative 2-D Echo revealed aortic valve regurgitation in 8 patients and mitral valve regurgitation in 1 patient.Results Three patients died after operation ( mortality 8.8％ ).Severe complications included acute kidney injury in 13 cases,respiratory dysfunction in 12 cases,paraplegia in 1 case,mental disorder in 10 cases and excessive post-operative bleeding in 2 cases.Conclusion The incidence of the complications after total arch replacement is still high and severe.Intensive care should be stressed peri-operatively and early diagnosis and treatment for post-operative complications are important procedures.
