Surgical Treatment of Ventricular Septal Defect with Severe Pulmonary Hypertension in 37 Patients / 中国医师杂志

ABSTRACT

Objective To summarize the operative experience of ventricular septal defect(VSD) with severe pulmonary hypertension(PH).Methods 37 patients with VSD complicated with severe PH,who underwent surgical repair were treated combinatively in perioperative period including resting,oxygen inhalation,and administration of captoprill and prostaglandin E 1(PGE 1).All of the patients were operated by cardiopulmonary bypass with moderate hypothermia.Arterial oxygen saturation(SaO 2),pulmonary arterial pressure and cardiac function were observed before and after operation,and progression of cardiac function and mortality were followed-up after discharged.Results 2 patients died of low cardiac output syndrome(LCOS) and one patient died of respiratory failure,and the operative mortality was 8 1%.one patient was diad after 8 months and the cardiac function of 33 patients markedly improved.Conclusions Reasonable treatment in perioperative period and holding the indications for the operation strictly are the keys to decrease the mortality of the operation,and SaO 2 could be a simple measurement to identify the indication of operation and the prognosis of the patient with VSD complicated with severe PH.
