RESUMO

Antithrombotic agents are increasingly prescribed to older adults; however, they are associated with bleeding-related complications. We describe a case of intraoperative heparin resistance after administration of andexanet alfa (AA). An 81-year-old man was diagnosed with a ruptured internal iliac artery aneurysm. The patient required emergency endovascular aneurysm repair and was treated with AA because he was receiving apixaban. Despite high-dose intraoperative heparin administration, his activated coagulation time was not prolonged. Our findings suggest that AA should be administered with caution in patients experiencing potentially fatal bleeding (requiring surgical intervention) who are also receiving direct oral anticoagulants.

RESUMO

Surgical pulmonary embolectomy is indicated for acute massive pulmonary thromboembolism complicated by floating thrombi in the right heart system. Postoperative residual thrombi are associated with persistent pulmonary hypertension and subsequent right heart failure, resulting in poor surgical outcome. A 67-year-old man was admitted to our institution owing to dyspnea on exertion. Transthoracic echocardiography revealed a floating right atrial mass and right ventricular overload. In addition, enhanced computed tomography (CT) showed a right atrial mass as well as bilateral massive pulmonary embolism. We performed an urgent pulmonary embolectomy using a bronchoscope as an adjunctive angioscope to completely remove the peripheral thrombi and to prevent serious complications, such as endobronchial hemorrhage due to pulmonary arterial injury. A clear, bloodless view of peripheral pulmonary arteries was obtained using short intermittent circulatory arrest technique. Postoperative course was uneventful, and he was discharged ambulatory 20 days after the surgery without any symptoms.
