Saddle pulmonary embolus resulting in cardiovascular collapse requiring extracorporeal membrane oxygenation in a postoperative patient with endometrial cancer

BACKGROUND: Venous thromboembolism after open gynecologic surgery is not uncommon, especially in the presence of other risk factors such as obesity, prolonged surgical time or gynecologic malignancy. CASE: We present the case of a 62 y.o. patient who underwent open hysterectomy and surgical staging for uterine serous carcinoma. She was readmitted with lower extremity edema. During her workup, she underwent cardiovascular arrest secondary to saddle pulmonary embolus requiring cardiopulmonary resuscitation and extracorporeal membrane oxygenation. After systemic and catheter directed thrombolysis, and a long hospitalization, she was discharged home in stable condition. CONCLUSION: Saddle pulmonary embolus is a potentially catastrophic and fatal postoperative complication. This case demonstrates a successful implementation of directed thrombolysis, veno-arterial extracorporeal membrane oxygenation and multidisciplinary management in a case of postoperative saddle pulmonary embolus. PRÉCIS: We report a case of an endometrial cancer patient who sustained a massive postoperative pulmonary embolus and was successfully resuscitated using extracorporeal membrane oxygenation.
