摘要
作者采用乳突后开颅显微血管减压术治疗三叉神经痛５１２例中，遇到４例贯穿型血管压迫神经。行神经束膜纵行切开，将贯穿的血管沿着切开的神经束之间推向远侧端，使血管移开神经敏感区，并固定之。在切开的神经束之间充填减压材料使神经减压。术后止痛，面部感觉保留，随访１～３年无复发。作者观察到三叉神经感觉根出桥脑处有一段敏感区。血管压迫神经敏感区时可诱发疼痛。
AbstractOf 512 patients of trigeminal neuralgia who hadundergone microvascular decompression through a retromastoid craniotomy,4 were caused by microvas-cular compression of perforation type. In 3 patients,the perineurium of trigeminal nerve was cut longitud-nally,the nerve-tract was separated,the perforatingblood vessel was pushed to the distal end,and the ves-sel was made to leave the nerve sensitive area and thendecompression materials were put between the separat-ed nerve-tract.The patients were pain-free and the fa-cial sensation was preserved after operation,and no re-currence occurred in 1 to 3 years after operation. Theauthors realized that there is a sensitive area near the trigeminal nerve sensory root entry zone. When theblood vessel compresses the sensitive area,trigeminalneuralgia is induced,whereas the vessel decompressesthe area,the pain is free. So it is a good evidence forthe microvascular compression theory and it is moreimportant than the non-perforation type.
