Excimer laser-assisted nonocclusive anastomosis

Excimer laser assisted nonocclusive anastomosis (ELANA) is a technique in vascular surgery and neurosurgery to create a bypass without interrupting blood supply in the recipient blood vessels.

The ELANA technique is a subtle modification of existing methods to establish a connection between blood vessels (anastomosis) to create a bypass in or to the brain. The only real differences involve how the recipient artery is opened. In conventional techniques the recipient artery is temporarily interrupted (occluded with clips) and opened using microscissors or scalpel while in the ELANA technique blood flow is not intename for person
