Extrapulmonic Stenosis of the Pulmonary Veins

Extrapulmonic stenosis of the pulmonary veins.

Congenital stenosis of individual pulmonary veins.

CONGENITAL STENOSIS of individual pulmonary veins as they join the left atrium is a rare cause of pulmonary venous and arterial hypertension. Cases have been reported by Reye,1 Ferencz and Dammann,2 Andrews,3 Bernstein and associates,4 and Edwards.5' 6 Emslie-Smith and associates7 reported a patient with membranous occlusion of the pulmonary veins associated with pulmonary hypertension. The pur...

Stenosis of pulmonary veins with ventricular septal defect. A cause of premature pulmonary hypertension in infancy.

Pulmonary vein stenosis is recognised as a rare, silent cause of pulmonary hypertension. ' The condition can occur with or without intracardiac anomalies. '3 The presence of lesions, such as ventricular septal defect, which cause pulmonary hypertension in their own right, can make suspicion of associated pulmonary venous obstruction difficult. In only one of the four reported cases4-7 of ventri...

CT of the pulmonary veins.

Atrial fibrillation (AF) is a common cardiac rhythm disturbance and its incidence is increasing. Radiofrequency catheter ablation (RFCA) is a highly successful therapy for treating AF, and its use is becoming more widespread; however, with its increasing use and evolving technique, known complications are better understood and new complications are emerging. Computed tomography (CT) of the pulm...

Hemodynamic collapse due to the stenosis of four pulmonary veins in a patient with mediastinal tumor

Cardiogenic shock can occur due to compression of the four pulmonary veins and the left atrium by a mediastinal tumor. Steroid infusion can be a temporary alternative therapy before obtaining a definite diagnosis and performing an intervention with stents to dilate the pulmonary veins.
