Pulmonary wedge angiography

Pulmonary vein wedge angiography.

Visualization of the pulmonary arteries in pseudotruncus by pulmonary vein wedge angiography.

Pulmonary venous wedge angiography revealed the anatomy of the mediastinal and parenchymal pulmonary arteries in 22 patients with obstruction of the right ventricular outflow tract, proximal pulmonary arteries or branch pulmonary arteries, when conventional angiographic methods had failed. Nine of these patients had pseudotruncus-type anatomy and had no previous surgery. One pulmonary artery wa...

Magnification pulmonary wedge angiography in the evaluation of children with congenital heart disease and pulmonary hypertension.

In order to determine the presence and extent of obstructive pulmonary vascular disease in patients with congenital heart disease, magnified cineangiograms were obtained with a catheter in the pulmonary artery wedge position in 155 infants and children undergoing cardiac catheterization. The wedge angiograms (WA) were analyzed in groups according to the pulmonary hemodynamics: group A normal pu...

Overuse and underuse of pulmonary CT angiography in patients with suspected pulmonary embolism

Background: The aim of the present study was to evaluate the utilization and diagnostic yields of CT pulmonary angiography (CTPA) using the Revised Geneva score and Wells’ criteria, in patients with suspected pulmonary embolism (PE).    Methods: One hundred and twelve adult patients underwent CTPA for suspected PE were participated in this study. The outcome was positive or neg...

Radionuclide Pulmonary Angiography

A dramatic case of occlusion of the right pulmonary artery is presented. The diagnosis was clearly established by means of a lung scan and a radionuclide pulmonary angiogram. The entire course of the disease process was followed by radionuclide studies with a gradual but persistent return to normal. Due to the preciseness of the evidence presented, contrast angiography was not.thought necessary.
