Abstract: | The authors describe the occurrence of the thrombosis of the cerebral venous sinuses in a patient in coma due to a large hemispheric infarction attributed to the thrombosis of the left internal carotid artery. After his admission to the Intensive Care Unit, a fiberoptic catheter was advanced into the left internal jugular vein to monitor the jugular bulb blood oxygen saturation, and the controlater was catheterized In order to supply fluids and medications. Despite the aggressive treatment, the patient died and, at the autopsy a massive thrombosis of the internal jugular veins was found, which extended to all the sinuses, in the absence of evident carotideal abnormalities. The authors describe the possible mechanisms of the massive thrombosis. |
