A common cause of trigeminal neuralgia (TN) is compression of the root of the fifth cranial nerve by a tortuous basilar artery or one of its branches. Microvascular decompression surgery has proved valuable in relieving the symptoms of these patients with nerve compression. We performed vertebral angiography on 22 patients with TN. The angiographic appearances were compared with the findings obtained from an anatomic study in which the positions of 20 trigeminal nerves in the skull were determined radiographically in 12 cadavers. By using this information, we were able to predict the presence of arterial-nerve compression in 20 of the 22 patients, and these positions were later confirmed at surgery. We describe the angiographic findings in patients with TN as well as the findings in a control group of 159 individuals with no history of TN. From these preliminary results, angiography appears to be valuable in the preoperative evaluation of patients with TN.
三叉神经痛（TN）的一个常见病因是迂曲的基底动脉或其分支之一对第五颅神经根部的压迫。微血管减压手术已被证明对缓解这些神经受压患者的症状很有价值。我们对22例TN患者进行了椎动脉血管造影。将血管造影表现与一项解剖学研究的结果进行比较，该研究通过X线摄影确定了12具尸体颅骨中20条三叉神经的位置。利用这些信息，我们能够在22例患者中的20例中预测动脉-神经压迫的存在，这些位置后来在手术中得到证实。我们描述了TN患者的血管造影表现以及159例无TN病史的对照组的表现。从这些初步结果来看，血管造影似乎对TN患者的术前评估很有价值。
