在椎间孔外区，后支主干及其分支与出口腰神经前支的关系密切，血管呈“树叉”状从外侧将神经包绕。
In the out space of the foramens, the posterior branches located laterally to the exiting nerve and formed an "arbor" around it.
同时根据二叉树的前序遍历结果匹配血管段，有效地提高了匹配的速度和准确度。
Vessel segments in two images are matched by the preorder traversal of the binary trees, and the method is proved fast and accurate.
结果：32例单侧三叉神经痛及面肌痉挛的MRTA中，确认患侧有“血管压迫”28例，无血管压迫4例。
Result: Of the unilateral TGX and HFS' s MRTA findings, 28 of 32 cases were confirmed to be the symptomatic side with the vascular compression, except 4 cases.
结论三叉神经微血管减压术有较肯定疗效，可保留三叉神经功能，但需开颅，有一定风险，有一定的复发率。
Conclusions Microvascular decompression for trigeminal neuralgia was effective, and could preserve trigeminal nerve function, but it must take a risk of intracranial operation and partial recurrence.
目的：总结19年以来采用围套式显微血管减压术治疗912例三叉神经痛的经验教训。
Objective: To summarize the experience and lessons learned from 912 cases of trigeminal neuralgia treated by microvascular decompression with an encircling method for 19 years.
方法应用3d -CISS序列并结合3d - TOF血管造影及MPR重建技术对49例三叉神经痛患者进行MR检查并部分与手术结果对照。
Methods 49 patients with neuralgia were examined by MRI 3d-ciss in combination with 3d-tof and MPR technique. The MRI findings were compared to the partial operative results.
结论：A型肉毒素通过抑制三叉神经血管系统中降钙素基因相关肽释放和无菌性炎症反应而减轻偏头痛症状。
CONCLUSION: BTX-A can relieve migraine symptoms by inhibiting CGRP releasing from trigeminovascular system and preventing meningeal sterile inflammatory response.
