A New Method for Induction of Fibrous Renal Artery Stenosis in the Pig Designed for the Study of Percutaneous Balloon Catheter Dilatation

Abstract

An open surgical method for the creation of experimental renal artery stenosis by ligation with chromic catgut is described. Microscopic examinations at different intervals demonstrated the development of fibrosis throughout the arterial wall. These stenoses seem to provide a suitable model for the study of the effects of balloon catheter dilatation. Previously reported techniques for experimental artery stenosis induction are briefly reviewed.
