BACKGROUND: A high-flow bypass is theoretically more effective than a conventional low-flow bypass in preventing @entity64 in @entity1 with symptomatic @entity432 and a compromised hemodynamic state of the brain. OBJECTIVE: To study the results of excimer laser-assisted nonocclusive anastomosis (ELANA) high-flow extracranial-to-intracranial (EC-IC) bypass surgery in these @entity1 . METHODS: Between August 1998 and May 2008, 24 @entity1 underwent ELANA EC-IC bypass surgery because of transient @entity63 attacks or minor @entity385 associated with @entity432 . We retrospectively collected information. Follow-up data were updated by structured telephone interviews between May and September 2008. RESULTS: In all @entity1 , the ELANA EC-IC bypass was patent at the end of surgery with a mean flow of 106    41 mL/min. Within 30 days after the operation, 22 @entity1 (92%) had no major complication, whereas 2 @entity1 (8%) had a fatal @entity1779 . During follow-up of a mean 4.4    2.4 years, the bypass remained patent in 18 of the 22 surviving @entity1 (82%) with a mean flow of 141    59 mL/min. All @entity1 with a patent bypass remained free of transient @entity63 attacks and @entity385 . In 4 @entity1 , the bypass occluded, accompanied by ipsilateral transient @entity63 attacks in 2 @entity1 , ipsilateral @entity385 in 1 @entity1 , and contralateral @entity385 in another @entity1 . CONCLUSION: ELANA EC-IC bypass surgery in @entity1 with @entity432 is technically feasible and results in cessation of ongoing transient @entity63 attacks and minor @entity385 , but carries a risk of @entity86 .
