Acute Pulmonary Thromboembolism and Deep Vein Thrombosis during the Medical Treatment of Acute Aortic Dissection was Successfully Treated by the Combination of Inferior Vena Cava Filter Installation and Anti-Coagulant Therapy: A Case Report.

A 71-year-old woman was admitted with Stanford type A acute aortic dissection (AAD). Computed tomography (CT) revealed thrombosis of the false lumen, and we planned to treat medically. She developed transient pleural effusion and hypoxemia, which persisted despite her pleural effusion disappeared. We performed CT and found a large thrombus in the pulmonary artery and femoral vein. We administered low dose- unfractionated heparin and installed a retrievable inferior vena cava filter, which caused the thrombus in the pulmonary artery to disappeared without exacerbating AAD. Our strategy seems to be suitable for acute pulmonary thromboembolism that occurs during the treatment of AAD.
