Peripheral pulmonary artery aneurysms in patients with pulmonary artery hypertension.

Pulmonary artery aneurysm (PAA), especially the peripheral type, is a rare disease. We report 2 cases of peripheral PAA with pulmonary artery hypertension. Complication associated with peripheral PAA was hemoptysis.

Portopulmonary hypertension: hemodynamics, pulmonary angiography, and configuration of the heart.

Background: The goal of the present study was to examine the cardiac configuration and pulmonary vascular changes in patients with portopulmonary hypertension (PPHTN) and compare them with those of idiopathic pulmonary arterial hypertension (IPAH).

Methods And Results: The subjects were 10 patients with PPHTN and 18 with IPAH. In PPHTN, the increases in the right ventricular end-diastolic volume index (89+/-19 vs 128+/-50 ml/m2; p=0.
