The Pathologic Basis of Angioplasty

Abstract

Transluminal angioplasty apparently increases lumen diameter by compression and remodeling of [Canine] atheromatous material. Recently, a new concept explaining the mechanics of angioplasty was described which challenges the classic concept of Dotter. Arterial balloon dilatation apparently is achieved by intimal disruption and overstretching of the arterial wall, not by remodeling of atheromatous material.
