Abstract
BACKGROUND
Superficial temporal artery-middle cerebral artery (STA-MCA) bypass helps treat cerebral ischemia. However, the STA is not available for bypass in some conditions. Therefore, with some technical tips, the authors introduced a bypass technique using the occipital artery (OA).
CASE SUMMARY
Two female patients complained of hemiparesis. Brain magnetic resonance imaging (MRI) indicated contralateral infarction from the MCA steno-occlusion. On Diamox single photon emission computed tomography or perfusion MRI, the contralateral front parietotemporal reserve was diminished. On transfemoral cerebral angiography, the STA was thin with a weak flow; however, the OA was prominent. Direct OA-MCA end-to-side extracranial-intracranial bypass surgery was implemented instead of STA because the caliber was too narrow. The postoperative course was uneventful in both cases, with well-maintained bypass patency and neurological stability during follow-up.
CONCLUSION
OA might be an acceptable alternative for MCA cerebral ischemic cases with an unsuitable STA.
Core Tip: In cases of cerebral ischemic disease or progressive ischemia where the Superficial temporal artery is unsuitable in the middle cerebral artery territory, occipital artery might be an acceptable donor artery for a less invasive EC-IC bypass surgery.
