ELANA: Excimer Laser-Assisted Nonocclusive Anastomosis for Extracranial to Intracranial and Intracranial to Intracranial Bypass.

ELANA, excimer laser-assisted nonocclusive
anastomosis, is a technique using an excimer laser/catheter
system for intracranial bypass surgery of the brain. The technique
has been developed over the past 12 years by Tulleken and colleagues
at UMC Utrecht in The Netherlands for treatment of primarily
untreatable giant aneurysms. The emergence of transplanted
conduit bypass is a valuable technique for managing these lesions
and the subsequent development of ELANA bypass. The ELANA technique
allows the operating surgeon to perform an extracranial-to-intracranial
or intracranial-to-intracranial bypass using a transplanted
large caliber conduit without occlusion of the recipient artery,
thus eliminating intraoperative ischemic insult related to
temporary occlusion time.
