Vein Glossary


Aneurysm of the Vein
The definition is a ballooning of the vein at greater than 1.5x the diameter of the adjacent veins. Aneurysms can be benign and cause no problems or they can be the source of a clot that can travel to the lungs (pulmonary embolus). The treatment depends on the location and the nearby anatomy.
