Paper Abstract

Stenotic or occlusive (two different techniques) lesions were surgically induced in the canine common carotid artery. The lesions were evaluated angiographically prior to as well as after laser angiosurgery (LAS). LAS was performed in 30 dogs using a continuous wave (CW) argon ion laser (Innova 20) coupled to a multifiber, quartz-shielded, fiberoptic catheter. Successful removal of lesion tissue was achieved in 89% of the animals with stenoses and in 40% and 82% in each of the two groups of dogs with occlusions. In the latter two groups, perforation of the vessel wall during LAS was encountered in 60% and 18%, respectively. No perforations occurred in the stenotic animals, where long-term follow-up was possible for up to 60 days with a patency rate of 63% and morphological evidence of excellent healing with complete reendothelialization.
