Serious cerebral complications following unilateral ligation of the internal jugular vein. Review of the literature and a case report.
Rolffs J, Schmelzle R.

Abstract
Serious intracranial sequelae of unilateral internal jugular vein ligation or resection are extremely rare. 22 cases including our own, were found in the literature, eight of them with a fatal outcome. Factors involved such as abnormalities of the cerebral venous sinus system, controlled hypotension, hypovolemia, posture, and dressings are discussed, as well as safeguards and possible preoperative diagnostic measures.
