Methods Clinical data, anesthesia methods and outcome of 6 pregnant women with pulmonary hypertension were analyzed. Among them, 1 case of patent ductus arteriosus had to undergo cesarean section twice, because the interval time of twice cesarean section was longer (2 years), and the number of pregnant women was counted to 7 cases. Results Seven patients had to undergo cesarean section with general anesthesia, and all the pregnant women′s hemodynamic were stable during the operation. After operation, 1 pregnant woman discharged from hospital against the doctor′s advices because of massive brain infarction, and the others were all rehabilitated. Seven newborns status:preterm in 3 cases, cardiopulmonary resuscitation in 2 cases, the Apgar score of the others newborns was 9-10 scores. Conclusions Pregnant women with pulmonary hypertension have high peri-operative risk, especially those who undergo general anesthesia. To improve the survival rate, anesthetist should reinforce the perioperative care, maintain oxygen supply, reduce the stress response, maintain the preload and blood pressure, and avoid the increasing of pulmonary pressure.
