自1985年3月至1990年8月,手术治疗单纯先天性室间隔缺损合并重度肺动脉高压16例。所有病例的肺动脉收缩压≥12kPa(90mmHg),主肺动脉与体动脉收缩压比值(P_p/P_(?))≥1.00。手术死亡率6.25%。本文就术前状况和手术危险性提出了一种综合评估法。认力右下肺动脉直径同胸廓横径比率(RIPA/T)、肺、体循环阻力比(R_p/R_s)、肺、体循环血量比(Q_p/Q_s)、肺动脉平均压(mPAP)和血氧饱合度(SaO_2)是估计手术危险性的主要参数。同时简单介绍了一种新的室间隔缺损修补术。
From March 1985 to August 1990, surgical treatment of simple congenital ventricular septal defect complicated with severe pulmonary hypertension in 16 cases. The systolic pressure of pulmonary artery in all cases was ≥12kPa (90mmHg), and the systolic pressure ratio of main pulmonary artery to body artery (P_p / P_ (?)) ≥1.00. Surgical mortality rate 6.25%. This article presents a comprehensive assessment of preoperative status and surgical risk. The ratio of right lower pulmonary artery diameter to thoracic diameter (RIPA / T), lung to systemic resistance ratio (R_p / R_s), pulmonary to systemic blood volume ratio (Q_p / Q_s), mean pulmonary artery pressure (mPAP) The degree of agreement (SaO_2) is the main parameter to estimate the surgical risk. At the same time a brief introduction of a new ventricular septal defect repair.
