VAZQUEZ MUNOZ, E.; RIOS BLANCO, J. J.; GOMEZ CEREZO, J.  and  BARBADO HERNANDEZ, F. J.. Diagnosis with helical CT and echocardiography of patients with suspected chronic thromboembolic pulmonary hypertension. An. Med. Interna (Madrid) [online]. 2003, vol.20, n.7, pp.35-38. ISSN 0212-7199.

Chronic Thromboembolic Pulmonary Hypertension (CTEPH) is a serious disease with a very high mortality after variable periods of time. Early diagnosis of CTEPH is critical because thromboendarterectomy can improve survival, hemodimamics and functional capacity. Based on our  experience we have performed a review of diagnostic techniques. Echocardiography, pulmonary angiography, fiberoptic angioscopy, helical CT an MRI. For each diagnostic procedure we have analysed its accuracy, invasiveness and easiness of use. We conclude that currently the most useful techniques are echocardiography (to asses pulmonary hypertension), and helical CT which is a good alternative to pulmonary angiography and can detect very specific findings such as dilatation of central pulmonary arteries, eccentric localized thrombi and mosaic attenuation of the pulmonary parenchyma. Even more accurate findings can be expected by the use of multislice CT, which could alow to asses the degree of narrowing of the pulmonary vessels and bronchial circulation.
