[Recanalization of arterial occlusions by laser].
Recanalization of arterial occlusions by laser light application has attracted much interest in recent years. Extensive investigations have been carried out to evaluate the optimal delivery system, in order to minimalize the rate of perforation. Systems based upon conversion of laser energy to thermal energy has been tried out. The laser probe as well as the sapphire tip create a channel through the occlusion by thermal ablation. A guide wire is thereafter passed through the narrow channel in order to perform an ordinary balloon dilatation. Other lasers are currently being investigated. Both the lasers themselves and the required disposable equipment, are relatively expensive. Laser recanalization of arterial occlusions is still being investigated. The clinical benefit in the therapy of arterial disease remains to be seen.
