Clinical analysis of pregnancy termination in 167 pregnant women with cardiovascular disease during the first and second trimester / 中华妇产科杂志

ABSTRACT

Objective:To study the risk assessment, method selection and clinical management of pregnancy termination during the first and second trimester of pregnant women with cardiovascular disease.Methods:This study focused on pregnant women with cardiovascular diseases who were admitted to Beijing Anzhen Hospital during the first and second trimester of pregnancy from January 2016 to September 2019, to summarize their clinical characteristics, reasons and methods of pregnancy termination, management and outcomes.Results:Among 167 pregnant women, 119 cases (71.3%, 119/167) were in early pregnancy and 48 cases (28.7%, 48/167) were in middle pregnancy. The reasons for termination of pregnancy were cardiovascular disease (109 cases; 65.3%, 109/167), unwanted pregnancy (54 cases; 32.3%, 54/167) and other reasons (4 cases). Vacuum aspiration was performed in 98 cases and forceps curettage was performed in 19 cases, medical abortion was performed in 2 cases in early pregnancy. There was no change in cardiac function after pregnancy termination and all survived in early pregnancy. In the second trimester, 16 cases were induced by intraamniotic injection of ethacridine, 2 cases by water balloon, 1 case by oxytocin intravenous drip, and 29 cases by hysterotomy delivery. The ratio of patients with hysterotomy delivery with cardiac function grade Ⅲ-Ⅳ was significantly higher than that in the patients with vaginal labor induction in the second trimester [79% (23/29) vs 4/19; P<0.01]; the ratio of pregnancy risk grade Ⅳ-Ⅴ was also significantly higher [100% (29/29) vs 14/19; P=0.007]. The mean length of hospital stay of patients with hysterotomy delivery was significantly longer than that in the patients with vaginal labor induction [(7.1±3.4) vs (2.4±1.8) days; P<0.01]. Cardiac function was improved in 4 patients induced by ethacridine and rapid recovery without serious complications. Cardiac function decreased in 5 cases and 1 case died on the first day after hysterotomy delivery. Conclusions:Pregnancy risk assessment should be conducted as early as possible in patients with cardiovascular disease. If it is not suitable to continue the pregnancy, terminate pregnancy as early as possible to reduce the risk. Pregnancy termination methods and analgesic methods should be selected according to different gestational age and complications. The indications for hysterotomy delivery should not be relaxed at will, so as to minimize trauma and hemodynamic changes. After the termination of pregnancy, contraceptive measures should be implemented and the next treatment plan should be guided.
