Human Atherosclerotic Coronary Artery Xenografts: A Model for Investigation of Transluminal RecanalizationDivision of Cardiology, Hospital Bogenhausen
Laboratory Animal Facilities GSF, Neuherberg/Munich, West Germany
Institut of Pathology, Hospital Bogenhausen, Munich A model for testing transluminal recanalization techniques was developed. Fragments of human atherosclerotic coronary arteries were transplanted into carotid arteries of dogs and evaluated by angiographic, angioscopic, and histo logic study within a three-month period. An inflammatory response was most intense within the first week. By two weeks no inflammation was noted. Total occlusion (n = 13) and stenosis (n = 11) of the carotid arteries were achieved without complications. The model is easy to produce within a short period and the arterial occlusion resembles human vascular disease. This model has been used to evaluate laser recanalization of vascular obstructions.
