Abstract

Renal artery embolization was induced experimentally in rabbits and microvascular changs were studiedangiographically, microangiographically and histopathologically. The results were as follows; 1. The mainmicroangiographic findings of renal artery embolization were arterial occlusion and collateral vessels arecharacterized by spiralling, dilatation, irregular lumen with abrupt caliber change, disoriented course andincreased number. 2. Collateral vessel formation was demonstrated in all cases of renal artery embolization bymicroangiography. 3. Recanalization of embolized vessels was better visualized by renal angiography thanmicorangiography. It was considered that microangiography is a valuable method for the observation ofmicrovascular changes in renal artery embolization and other renal diseases.
