Chronic thromboembolic pulmonary hypertension--diagnosed on spiral CT angiography.

Chronic thromboembolic pulmonary hypertension (CTEPH) is a part of the spectrum of venous thromboembolism in which pulmonary thrombus fails to resolve, resulting in occlusion of the major pulmonary artery. Diagnosis of this disease is important as it is potentially curable by pulmonary thromboendarterectomy. A case of CTEPH diagnosed non-invasively on spiral computerized (CT) pulmonary angiography is reported.
