Management of petrosal veins during microvascular decompression for trigeminal neuralgia.
Venous compression might be the main cause of incomplete decompression and symptom recurrence after microvascular decompression (MVD) in patients with trigeminal neuralgia. Although it can be killed in most cases, cutting the vein sometimes has the potential risk arising from venous congestion. To maneuver the vein safely, we introduced a temporary occlusion test of the vein. ⋯ This venous occlusion test could help the surgeon in making a right decision before manipulation of the petrosal veins during MVD.
