EVRF Radiofrequency CR45i Histology By Doctor Atilla Szabo Budapest, hungary

Method Taking samples of treated sheep leg veins Samples were fixed in formaldehyd and examined under microscope 200x and 600x magnification was used

Findings Clear difference between untreated and treated veins Treated veins showed the desirable desintegration of the endothelial layer Adherent thrombus formed in the lumen after treatment Damage to muscle cells and elastic fibres due to thermal damage caused by RF with the CR45i catheter

Vein wall before and after EVRF treatment – HE stain, 200x Normal endothel Desintegrated endothel cells, thrombus formation Intact media layer Desintegrated, blown up muscle cells and elastic fibers due to thermal damage

Vein wall before and after EVRF treatment – HE stain, 600x Desintegrated endothel cells Normal endothel Desintegrated, blown up muscle cells and elastic fibers due to thermal damage Intact media layer
