Rescue revision techniques for end-to-side anastomosis: Technical note

BACKGROUND: Extracranial-intracranial bypass operation is an essential procedure for cerebrovascular surgeons. Proper procedure of the bypass requires special skills, selected instruments, and training in the microsurgical laboratory. In spite of the high success rate for extracranial-intracranial bypass, a potential pitfall while performing an end-to-side anastomosis is poor blood flow or occlusion at the anastomotic site during surgery. If this happens, revision procedure is necessary. METHODS: We introduce our salvage techniques for anastomosis revision with or without recipient artery occlusion. RESULTS: With this method, ischemic complication related to revision procedure minimizes ischemic complications. CONCLUSIONS: The present technique is a simple method for anastomosis revision.
