Microvascular relations of the trigeminal nerve : an anatomical studyKlun, Boris ; Prestor, BorutThe neurovascular relationships in the trigeminal root entry zone were studiedin 130 trigeminal root entry zones of 65 cadavers. No history of facialor trigeminal pain had been obtained during life ... in these subjects. The technique of intravascular injection, which allowed good visualization and evaluation of the neurovascular relationships, is described. A total of 42 examples of contact with the root entry zone and 10 examples of compression were identified. In 30 of the examples of contact, the finding could be related to an artery; in the other examples, it appeared to be due to veins. Of the arterial compressions, the superior cerebellar artery was responsible in 53.8 percent, the anterior inferior cerebellar artery was responsible in 25.6 percent, and pontine branches of the basilar artery were responsible for the remaining 20.6 percent. Only one instance of unequivocal compression by a vein was found. Other anatomical observations of interest are reported. The absence of a history of trigeminal neuralgia in the 7 percent of examined nerves in which root entry zone showed arterial compression is in marked contrast to the finding of 80 percent or more in the operative series for trigeminal neuralgia. It seems that vascular compressions may be the predominant but not the sole cause of trigeminal neuralgia.Source: Neurosurgery. - ISSN 0148-396X (Letn. 19, št. 4, 1986, str. 535-539)Type of material - article, component partPublish date - 1986Language - englishCOBISS.SI-ID - 21926873
