Conference paper


The pathology of CO2-millwatt-Laser induced aneurysms has previously described in detail (1) In our experiment the modified 1.318 µm Nd:YAG-Laser was used in a reconstructive fashion, producing laser-assisted abventitia patches. Aneurysms were present at the patch site in 29 of 30 animals. Althroufh aneurysm clipping is commonly done in patients, there are aneurysms with broad base, where clipping wrapping or coating may not be possible. Our aneurysm model seems to be an effective model to stady obliterations of broad base aneurysms by laser or balloons.
