Abstract
Dolichoectasia of vertebrobasilar artery is an uncommon and rare cause of trigeminal neuralgia. The article presents a case of successful treatment of a patient with trigeminal neuralgia caused by vertebrobasilar dolichoectasia. The technical complexity of the operation is due to the rigidity and tortuosity of a large-caliber vessel with perforating branches leading to the brain stem and limited space in the cerebellopontine angle. The implantation of Teflon wool in areas of neurovascular conflict is an effective surgical aid for complete elimination of trigeminal neuralgia while maintaining the anatomical integrity of the nerve structures and minimizing the risk to the patient.
