血管减压术后三叉神经痛复发的再手术治疗

Repeat operations for recurrent trigeminal neuralgia after microvascular decompression

为探讨三叉神经痛复发的原因及治疗 ,对 12例显微血管减压术后复发的三叉神经痛患者进行了再手术。术中发现 10例三叉神经根部有血管袢再压迫 ,2例无血管压迫。经再次神经血管减压术或神经松解术治疗后疼痛消失 ,术后追踪观察 6个月～ 4年无复发。

For the study of cause and treatment of recurrent trigeminal neuralgia,repeat ope rations were performed in 12 patients with recurrent trigeminal neuralgia after microvascular decompression.Among repeat operations,there was vascular loop recompression at trigeminal root in 10 patients,negative exploration in 2 patients.The pain relief was achieved after neurovascular redecompression or neurolysis in all patients.The patients had no recurrent pain during a follow up from 6 months to 4 years.The causes of recurrent trigeminal neuralgia after microvascular decompression and the questions related to repeat operations were discussed.
