巨大冠状动脉瘤的外科治疗

目的探讨巨大冠状动脉瘤的临床特点和外科治疗要点。方法1996年7月至2004年10月,共手术治疗6例巨大冠状动脉瘤。外科治疗方法采用冠状动脉瘤切除术3例,同期冠状动脉旁路移植术2例、冠状动脉瘤成形术3例。巨大冠状动脉瘤常合并其他心血管疾病,同期行冠状动脉瘘修补手术4例,主动脉瓣置换术3例,主动脉成形术2例,冠状动脉瘤血栓清除术1例。结果所有患者均康复出院,平均体外循环时间(144±26)min(67～207min)。主动脉阻断时间(104±21)min(56～172min)。患者随访8～87个月(平均48个月)。随访中患者症状均消失,无死亡和冠状动脉瘤复发病例。结论巨大冠状动脉瘤是一种严重的心血管疾病,应及时手术治疗。

Surgical treatment of giant coronary artery aneurysm

OBJECTIVE: To discuss the clinical features and surgical treatments of giant coronary artery aneurysm (CAA). METHODS: From July 1996 to October 2004, 6 giant CAA patients were underwent surgery at Fuwai hospital. Three cases were underwent CAA resection, 2 concomitant coronary bypass, 3 reconstruction. The giant CAA was often combined with other cardiac diseases. Four cases underwent additional procedures of fistula closure, 3 aortic valve replacements, 2 aortoplasty and 1 thrombus cleaning at the same time. RESULTS: All patients recovered uneventfully. The mean of cardiopulmonary bypass time was (144 +/- 26) min (range 67 to 207 min). Aortic crossclamping time was (104 +/- 21) min (range 56 to 172 min). Patients follow-up time occurred from 8 to 87 months (mean of 48 months). All patients were free of symptoms during follow-up. None of the patients died during the follow-up period and none of the CAA recurred. CONCLUSIONS: The giant CAA is a serious cardiovascular disease, early diagnosis and surgical treatment are mandatory.
