Ophthalmodynamic Studies in Kinking of the Internal Carotid Artery. Surgical Implications

Summary

In 6 patients with kinking of the internal carotid artery and 10 healthy volunteers ophthalmodynamographic studies were performed. Sideward head bending in the patients caused major ipsilateral decrease of internal carotid flow as did forward flexion on both sides. This effect was minimal in healthy humans. Intraoperative monitoring by the same method showed instant improvement of flow dynamics after kink resection and end-to-end anastomosis.
