Pulmonary hypertension secondary to thromboembolism is a serious and debilitating disease. It occurs in approximately 0.5-1.0% of patients who survive an episode of acute thromboembolism. This is the first reported case of successful thromboendarterectomy performed in an elderly patient in Brazil. The patient, an 80-year-old man, presented favorable postoperative evolution. The authors believe this surgical procedure is a viable option for treatment of this type of pulmonary hypertension even in patients of advanced age, providing that there are no comorbidities.
