Percutaneous trigeminal tractotomy is an ablative procedure that can be used to treat trigeminal neuralgia in patients who have failed prior pharmacologic and surgical treatments. Using perioperative computed tomography (CT) guidance, ablation of the descending spinal trigeminal nucleus and trigeminal tract can be performed precisely to mitigate damage to surrounding structures. These patients are subsequently followed with postoperative imaging and clinical visits to assess long-term pain relief.

三叉神经痛经皮三叉神经牵引术：术后MRI检查结果

经皮三叉神经牵引切断术是一种消融手术，可用于治疗先前药物和手术治疗失败的患者的三叉神经痛。使用围手术期计算机断层扫描 (CT) 引导，可以精确地消融下行三叉神经核和三叉神经束，以减轻对周围结构的损伤。随后对这些患者进行术后影像学检查和临床访问，以评估长期疼痛缓解情况。
