Clinical efficacy and related factors of microvascular decompression in the treatment of trigeminal neuralgia

Abstract

Objective To investigate the clinical efficacy and related factors of microvascular decompression in the treatment of trigeminal neuralgia. Methods The clinical data of 40 patients with trigeminal neuralgia were analyzed retrospectively. Patients with trigeminal neuralgia were treated by microvascular decompression, and the clinical efficacy of microvascular decompression in patients with trigeminal neuralgia was analyzed statistically. The related factors on effect of microvascular decompression for trigeminal neuralgia were analyzed with Chi-square test and Logistic multivariate regression. Results After treatment, there were 39 patients with effective treatment, the total effective rate was up to 97.5%, and one case was no significant improvement. Of the 39 cases, 35 cases were complete remission, four cases were significantly improved. At the same time, the single factor analysis showed that the type of trigeminal neuralgia, the operation of the blood vessels in the operation and the preoperative magnetic resonance examination did not find the vascular compression were the key factors affecting the effect of trigeminal neuralgia. Conclusions There is no evidence of vascular compression in the operation of the vessel and the preoperative magnetic resonance imaging, which is an important factor affecting the therapeutic effect of trigeminal neuralgia.
