Journal of Clinical Neuroscience, 09/25/09
Masuoka J et al. – The importance of preserving the deep cerebral venous outflow has been recognized in microvascular decompression for trigeminal neuralgia; however, few reports have described the details of complications arising from the sacrifice of the superior petrosal vein (SPV). During the procedure in a 77–year–old woman, some tributaries of the SPV complex were sacrificed to achieve microvascular decompression for right trigeminal neuralgia. Postoperatively, the patient was conscious and pain free; however, on postoperative day 1 she developed headache and nausea followed by a decreased level of consciousness. MRI revealed an extensive venous infarction in the right cerebellum. Sacrifice of the SPV may lead to serious, potentially life–threatening complications. Neurosurgeons should pay close attention to the management of the SPV to reduce the risk of venous complications.
