感染性心内膜炎合并脑血管并发症患者的心脏手术疗效分析

Effect of surgical treatment on patients with infective endocarditis complicated by cerebrovascular accident

  • 摘要: 目的 探讨感染性心内膜炎合并脑血管并发症(cerebrovascular accident,CVA)的手术治疗效果。 方法 回顾性分析2005年6月- 2015年9月于本院心血管外科接受手术治疗的符合Duke(1)标准的感染性心内膜炎合并术前脑血管并发症42例临床资料。男性26例,女性16例,年龄9 ~ 71(39.9±16.7)岁。单纯主动脉瓣受累10例,单纯二尖瓣受累24例,主动脉瓣合并二尖瓣受累6例,无瓣膜受累的左房黏液瘤2例。术前合并脑梗死32例,脑出血10例(包括合并脑梗死6例)手术中发现感染共累及瓣膜46个,术中置换机械瓣22个,生物瓣16个;6例行二尖瓣成形,10例行三尖瓣成形,2例行左房黏液瘤切除。 结果 手术前出现脑血管并发症的平均时间为65 d,术中发现瓣膜赘生物66枚,最大直径平均13.9 mm 42例中6例术后出现脑血管并发症,其中1例出现严重脑血管并发症后死亡。随访33例(80.4%),随访时间11.9 ~ 127.7个月4例出院后6个月内脑梗死,其中1例多发脑梗死后死亡;4例随访时仍有单侧肢体活动障碍等后遗症。1例手术后4年因夹层动脉瘤行Bentall手术,术后心功能Ⅲ级。 结论 合并脑血管并发症的感染性心内膜炎患者,积极手术治疗可提高治愈率,同时术后应加强颅脑检查及出凝血机制检测。

     

    Abstract: Objective To summarize the surgical treatment outcomes of patients with infective endocarditis (IE) complicated by cerebrovascular accident (CVA). Methods A retrospective analysis of clinical data about 42 patients diagnosed with IE complicated by CVA in our hospital from June 2005 to September 2015 was conducted. There were 26 males and 16 females with the mean age of (39.9±16.7) years (ranging from 9 to 71 years). Of the 42 cases, 10 cases were single aortic valvular disease, 24 cases with single mitral valvular disease, 6 cases with multiple valvular disease, and 2 cases with left atrial myxoma. Types of CVA consisted of cerebral infarction (n=32) and cerebral hemorrhage (n=10, including 6 concurrent cerebral infarction). Totally 46 valves were involved, 22 cases had mechanical valve replacement, 16 had biovalve replacement, 6 had mitral valve repair, 10 had tricuspid valve repair and 2 had left atrial myxoma resection. Results The average day between new-onset CVA and surgery was 65 d. Sixty-six vegetations were found intraoperatively with the mean maximum size of 13.9 mm. Of the 42 patients, 6 patients had cerebrovascula accident post-operatively and one of them died because of severe CVA. Thirty-three patients were followed up (80.4%) with the duration of 11.9-127.7 months. Of the 33 cases, 4 had cerebral infarctions including one who died of multiple cerebral infarction One underwent Bentall surgery because of dissecting aneurysm whose cardiac function corresponded to New York Heart Association class Ⅲ after surgery. Conclusion IE patients with CVA should accept surgical treatment, and head CT scan and hemagglutinin should be emphasized after surgery.
