Laser photocoagulation for treatment of experimental aneurysms

Abstract

Twenty‐five autologous, artificially implanted venous and arterial aneurysms were treated by argon laser photocoagulation. Sequential angiographic follow‐up studies and final histologic studies demonstrated complete secondary occlusion in 11 cases, significant reduction of the aneurysm lumen in 10 cases, and no change in 4 cases. Delayed secondary occlusion appears to involve an active biologic process with progressive fibroblastic proliferation in the aneurysm wall.
