Method Thorax CT revealed a lesion of 40x43 mm enveloping left main pulmonary artery and bronchi in left hilus. Chest and Cardiovascular surgery council planned an intervention consisting of left pneumonectomy across pericardium, because of suspicion of left main pulmonary artery invasion, vascular graft interposition to left main pulmonary artery and emergent cardiopulmonary bypass if necessary.

The dilatation of pulmonary artery is a rare condition and called as pulmonary artery aneurysm. Aneurysm of both the pulmonary trunk and the ascending aorta is even rarer. Symptoms are due to aneurysm compression in adjacent anatomical structures. The main indicator of treatment is the pulmonary artery pressure. The prognosis and treatment of pulmonary artery aneurysm is unclear. Herein we pres...

PURPOSE We aimed to determine the correlation between flow characteristics of the proximal pulmonary arteries and vena cava obtained by 3.0 T phase-contrast magnetic resonance imaging (MRI) and hemodynamic characteristics by right heart catheterization in patients with chronic thromboembolic pulmonary hypertension. MATERIALS AND METHODS Twenty consecutive patients with chronic thromboembolic ...

Primary pulmonary hypertension is often associated with angina-like chest pain of uncertain etiology. Left main coronary artery compression by the pulmonary artery is a treatable cause of angina and should be considered in these patients. We describe a patient presenting with primary pulmonary hypertension, clinical angina and extrinsic compression of the left main coronary artery by the pulmon...

    Background: Since pulmonary angiography is the only non-invasive method for diagnosing pulmonary embolism, the use of radiation reduction methods without affecting the quality of images seems necessary. One of the simplest reasons for unnecessarily increasing of patient exposure is repetitive imaging due to poor image quality. Therefore, it is necessary to identify and ...
