Abstract
The chapter describes the possibilities of recording the three most important collateral pathways in occlusive disease of the brain-supplying arteries: detection of an ophthalmic collateral by Doppler sonographic examination of the periorbital arteries, assessment of the circle of Willis with color coded duplex sonography as well as indirect evidence of leptomeneal anastomoses. In rare cases, to clarify existing collateral pathways before planned surgical or interventional measures on the brain-supplying arteries, a carotid compression test is still recommended.
