[Microvascular decompression in trigeminal neuralgia following vertebrobasilar dolichoectasia].

MVD is an effective option in the treatment of TN following VBD. In these cases, operation is technically more difficult compared to MVD with intact vessels. However, surgery is much more effective than all the available alternatives. The possibilities of vessel transposition in VBD with or without fixation are limited and ineffective. Teflon wool interposition at the points of conflict is an effective and sufficient technique.
