    The STA-MCA bypass is a crucial EC-IC revascularization technique for conditions like moyamoya disease and complex aneurysms.

  • 2

    Meticulous dissection of the STA is essential to prevent vasospasm and ensure adequate vessel length for anastomosis.

  • 3

    The MCA serves as the recipient artery, requiring precise microsurgical dissection to avoid injury to surrounding structures.

  • 4

    Preoperative assessments, including vascular imaging and cerebral perfusion evaluation, are vital for successful bypass outcomes.

  • 5

    Intraoperative techniques include maintaining normotension and using ICG angiography for optimal vessel selection and flow assessment.
