Mechanical Thrombectomy of a Submassive Pulmonary Embolism in the Second Trimester of Pregnancy

Abstract

Venous thromboembolism (VTE) represents a potentially severe and infrequent complication that can occur in the pregnant population. The nuance in recognizing and diagnosing this condition can be quite difficult due to the changes that occur during pregnancy. This case highlights the importance of diagnosing pulmonary embolism in pregnancy, classifying the degree of disease, and determining the best treatment for both mother and fetus. Although rare, early diagnosis and treatment are crucial in order to reduce morbidity and mortality.
