【摘要】 目的探讨动脉干下型室间隔缺损的临床特点及手术疗效观察,掌握本病的手术适应证及术式选择。方法通过1993年1月～2003年8月在我院收治的149例动脉干下型室间隔缺损的患者,观察随年龄增长和肺动脉高压、主动脉瓣病变发生发展规律的关系及术式选择对预后的影响。结果①随年龄增长,合并主动脉瓣病变明显增加。12岁以后出现主动脉瓣病变者占39%。②较大缺损易产生心力衰竭,早期导致肺动脉高压。③中、小两大动脉的干下室缺,易引起主动脉瓣脱垂和返流。④此类室缺应早期手术,以补片修补为主,如合并主动脉瓣脱垂应及早行室缺修补及主动脉瓣成形术。结论根据两动脉干下室间隔缺损的临床特点应及早手术治疗,且以补片修补为主。更多还原

【Abstract】 Objective To determinate the operative indication and mode of operation by reviewing the clinic character of subar-terial ventricular septal defect and outcome of surgery management.Methods 149patients(from1993.1to2003.8)underwent repair of ventricular septal defect with subarterial ventricular septal defect were studied.Investigate the relationship between Age、pulmonary hypertension、aortic valve changes、operative mode and effectiveness of operation.Results①The cases associated with aortic valve changes were significantly increased with the growth of age.In the group over12years old,the cases with aortic valve changes were39percent.②Congestive heart failure and pulmonary hypertension were emerged earlier in the cases with large size of defect.③More cases with middle and small size of defect were associated aortic valve prolapse.④The defect was repaired with patch and aortic valve with prolapse was repaired as early as possible.Conclusion The patients with subarterial ventricular septal defect should undergo surgery management as early as possible.The defect was repaired with patch.更多还原
