Fifteen years ago laser was supposed to open arteries, now it is supposed to close veins: what is the reality behind the tool?

Perspectives in Vascular Surgery and Endovascular Therapy
Manju Kalra, Peter Gloviczki

Abstract

Laser first emerged as a technology for use in the vascular arena nearly 20 years ago. The ability of laser to evaporate atherosclerotic plaque was extensively studied; however, the goal of creation of an adequate channel without arterial wall perforation proved to be elusive, and the technique fell into disfavor. More than a decade later, interest in lasers was sparked again with its application to endovenous thermal ablation of axial superficial venous reflux. The mechanism of action of endovenous laser therapy involves thermal damage of the vein wall, resulting in destruction of the intima and collagen denaturation of the media with eventual fibrotic occlusion of the vein. Apart from the obvious attraction of a minimally invasive procedure to ablate superficial venous reflux with its attendant benefits, another advantage of laser ablation includes a potentially decreased incidence of neovascularization in the groin secondary to preservation of superficial venous drainage of the abdominal wall. Early success in terms of ablation of the refluxing saphenous vein has been reported as 90% to 95%. Minor complications are reported in 3% to 10% of patients and include bruising around the puncture site, transient paresthesias, superf...Continue Reading

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.

Atherosclerosis Disease Progression

Atherosclerosis is the buildup of plaque on artery walls, causing stenosis which can eventually lead to clinically apparent cardiovascular disease. Find the latest research on atherosclerosis disease progression here.
