Uterine Fibroid-Associated Massive Pulmonary Embolism: A Report of Two Cases.

This report details cases of uterine fibroid-associated deep vein thrombosis leading to massive pulmonary embolism, as well as the likely associated physiology. Two women, aged 33 and 37, presented with fibroid-associated pulmonary embolism. They both had large uterine sizes and no underlying thrombophilia. Case 1 had an uncomplicated course, whereas Case 2 had a course complicated by cardiac arrest and prolonged recovery. The presence of fibroids enhances coagulation and platelet adhesion. Mechanical compression also plays a role in predisposing to thrombosis. There may be a role for preoperative screening, especially in those with an elevated estimated uterine weight.
