Middle Cerebral Artery (M2) Dissection: STA-MCA Revascularization

Woringer and Kunlin performed the first documented extracranial-intracranial (EC-IC) bypass in humans in 1962. This procedure was performed between the common carotid and the intracranial arteries. Unfortunately, the patient died from pneumonia during the postoperative period. However, this experience paved the way for the new era of cerebral revascularization.

Yasargil performed the first successful superficial temporal artery to middle cerebral artery (STA-MCA) bypass in humans in 1967. Since then, this procedure has evolved in its technique and indications. The current main indications for the STA-MCA bypass include:

  1. Cerebral ischemia
  2. Moyamoya disease
  3. Complex intracranial aneurysms
  4. Complex skull base tumors

Because there is much controversy about the true indications of this form of bypass, I will briefly review the history and implications of recent trials on the application of this operation.
