The incidence of chronic thromboembolic pulmonary hypertension secondary to acute pulmonary thromboembolism.

Introduction: Chronic thromboembolic pulmonary hypertension (CTEPH) is a curable and partially preventable complication, with a substantial incidence, leading to severe morbidity and mortality. The aim of the present study was to find out the incidence of CTEPH secondary to acute pulmonary thromboembolism (PTE) using non-invasive procedures such as ventilation/perfusion (V/Q) scintigraphy and pulmonary multidetector CT (MDCT) angiography in determining the diagnosis of CTEPH.

Materials And Methods: The study included a total of 99 patients diagnosed with initial PTE between January 2010 and December 2012.
