室间隔缺损并动脉导管未闭31例临床和血流动力学观察

The clinical and hemodynamic observations in 31 cases of ventricular septal defect combined with patent ductus arteriosus

本文通过31例 VSD 并 PDA 的资料分析,总结两者并存的诊断线索和依据,其要点包括:①VSD 和 PDA 体征共存;②只有 VSD 杂音而脉压>6.67kPa 和出现周围血管体征;③VSD杂音伴严重肺高压体征同时心尖有舒张期流量杂音;④导管尖端经 PDA 进降主动脉,或肺动脉水平平均血氧含量超过心室平均氧含量1.5容积;⑤可疑患者进行升主动脉造影。

In 31 cases of VSD combined with PDA,the clinical and hemodynamic figures were observed The pulmonary systolic pressure was>10.70kPa in 22 cases (70.98%).The ratio of pulmonary and systemic blood flow was>3:1 in 18 cases (58.1%).Therefore,their clinical characteristics were the sign of VSD complicated with serious pulmonary hyperten- sion.Based on data observed from these 31 cases,the clues to correct diagnosis before opera- tion are adviced in this paper.
