Pulmonary Vein Stenosis Program
About pulmonary vein stenosis
Pulmonary vein stenosis is a rare and serious condition in which there is an obstruction (blockage) in the blood vessels that bring oxygen-rich blood from the lungs back to the heart. It can be isolated to a single pulmonary vein, but most often occurs in multiple veins simultaneously.
The stenosis occurs due to an abnormal thickening and, thus, narrowing of the walls of the veins. Pulmonary vein stenosis frequently progresses. As a result, partial loss or even total obstruction of flow to a vessel or vessels may occur.
Surgery to widen the narrowed veins and catheterization to stretch the vessel are usually short-term solutions since the obstruction typically recurs within a month to six weeks.
