The article describes surgical techniques used in 11 cases for correcting loops and pathological tortuosity of the internal carotid arteries. Resection of the proximal segment of the artery with its reimplantation into the bifurcation of the carotid artery is the technically simplest method. In marked degeneration of the arterial wall in the region of the loop, the latter must be resected and arterial end-to-end anastomosis established. The authors describe a method which they developed for resecting a high loop of the internal carotid artery.
