Superficial temporal artery to middle cerebral artery bypass for flow augmentation

Abstract

In the lecture to follow, we provide an in-depth review of superficial temporal artery to middle cerebral artery (STA-MCA) bypass for flow augmentation. We begin with a brief review of the two broad categories of cerebral bypasses as well and the relevant pathologies treated. We then discuss some important landmark trials on the subject of STA-MCA bypass. Next, we focus on patient selection with an emphasis on hemodynamic assessment using non-invasive quantitative imaging methods. Revascularization technique is then described with a corresponding case example and a subsequent discussion on complications and future directions.
