P701 Usefulness of echocardiography in diagnosis and monitoring in patient with pulmonary embolism during pregnancy, a case report

Pulmonary embolism is one of the leading causes of maternal mortality despite a low incidence of during pregnancy. We present 32-year-old woman, in the 35 week of first pregnancy, admitted to the Intensive Care Unit with dyspnea, tachycardia, cyanosis. Echocardiography confirmed the presence of embolic material in the main trunk of pulmonary artery, spreading to the right pulmonary artery. D-dimer and troponin T level were elevated, BNP remained within the normal range. The risk in PESI scale was assumed as intermediate high. LMWH therapy was initiated, the patient was constantly monitored. Venous thrombotic disease in lower extremities was excluded by ultrasonography. The treatment was carried out under obstetric supervision. The clinical state gradually improved, the patient was hemodynamically stable. Serial echocardiographic testing, revealed gradual regression of changes in the pulmonary trunk. Normalization of troponins and lowering of BNP levels were observed. The pregnancy was terminated in 39 week, by cesarean section (obstetric indications). The LMWH was continued few days after delivery, as the patient started lactation. She decided to terminate lactation in a first week after delivery so the therapy was switched into rivaroxaban for at least 3 months. Echocardiography after 3 month confirmed lack of changes in pulmonary trunk, the risk of pulmonary hypertension was low. Echocardiography can be a method of choice for confirming and monitoring pulmonary embolism during pregnancy, in a situation of high or intermediate clinical risk and good visualization of changes in pulmonary arteries Abstract P701 Figure.
