[Medical treatment in patients with chronic thromboembolic pulmonary hypertension].

Pulmonary thromboendarterectomy is the treatment of choice in patients with chronic thromboembolic pulmonary hypertension (CTEPH). However, specific medical treatment of pulmonary hypertension (PH) can be an alternative or play a complementary role to surgery. Thus, in patients unsuitable for surgery due to distal thrombotic obstruction, residual or persistent PH after surgery or very severe PH and a high-risk hemodynamic profile, medical treatment may improve their clinical course and the outcome of thromboendarterectomy.
