Abstract:
ObjectiveTo evaluate the safety and efficacy o f microvascular deco mpression in the management of primary trigeminal neuralgia.Methods We review ed 13 patients with unilateral primary trigeminal neuralgia treated by microvasc ular decompression. Conventional spin-echo (SE) sequence and 3-D fast inflow wit h steady-state precession (3-D-FISP) sequence MRI scans were used preoperatively to find evidence of neurovascular compression. The operation was accessed by re trosigmoidal approach and the nerve root was separated away from pressure vessel s by artificial vascular patch.ResultsDuring operations it w as found that tr igeminal nerves were pressed on by blood vessels in all the cases (by the superi or cerebellar artery in 11 cases; by the basilar artery and the superior cerebel lar artery in 1 case; and by the vein in 1 case). Complete pain relief was achie ved in all the patients without mortality or permanent complications. Eleven pat ients were clinically followed for 6～24 months with a mean of 13 months, and no recurrence was seen. ConclusionsMicrovascular decompression is a safe and effective procedure in the treatment of primary trigeminal neuralgia.
