Abstract
We describe surgical treatment for a patient with chronic thromboembolic pulmonary hypertension who developed acute type A aortic dissection. Acute aortic dissection is a life-threatening disease and must be operated emergently, and chronic thromboembolic pulmonary hypertension can be treated only by pulmonary endarterectomy. We performed a staged procedure consisting of hemiarch replacement with antegrade cerebral perfusion first and pulmonary endareterectomy with periods of deep hypothermic circulatory arrest a week later. We used extracorporeal membrane oxygenation after aortic surgery as a bridge to pulmonary endarterectomy. Our strategy was useful for patients with chronic thromboembolic pulmonary hypertension who require complicated aortic surgery.
