摘  要:目的探讨立体定向双侧内囊前肢毁损术治疗难治性强迫症的疗效、安全性及机制。方法回顾性分析四川大学华西医院神经外科自2009年1月至2014年1月行立体定向双侧内囊前肢毁损术的14例难治性强迫症患者的术前、术后3个月及6个月临床资料,比较手术前后磁共振弥散张量纤维束成像(DTT)、脑葡萄糖代谢(PET/CT)、症状相关量表及部分认知功能量表评分的变化。结果术后3月DTT示内囊前肢联系前额叶与纹状体的前后纤维束大部分毁损,而术后6月部分纤维瘢痕修复再生。术后6月PET/CT显示眶额叶皮层(右:1.17±0.20,左:1.20±0.06)、腹内侧额叶皮层(右:1.20±0.02,左:1.18±0.07)、纹状体(右:1.17±0.04,左:1.12±0.06)、前扣带回(1.06±0.06)代谢较术前(右:1.41±0.19,左:1.40±0.16;右:1.26±0.02,左:1.23±0.08;右:1.35±0.10,左:1.37±0.12;1.23±0.07)降低,而枕叶皮层(右:1.58±0.14,左:1.63±0.21)与术前(右:1.39±0.14,左:1.41±0.15)相比代谢增加,差异均有统计学意义(P〈0.05);术后6月耶鲁。布朗强迫量表评分(9.00±4.94)、汉密尔顿焦虑量表评分(8.28±4.59)和汉密尔顿抑郁量表评分(6.14±2.24)分值较术前[(29.21±5.36、22.64±4.93、17.84±6.13)均明显下降,差异有统计学意义(P〈0.05);即刻/延迟逻辑记忆[(21.28±4.85)/(18.00±5.39)]、即刻/延迟视觉再生[(13.00±1.51)/(12.14±2.14)]及木块图测验(39.83±6.80)较术前[(17.21±5.61)/(14.00±5.34)、(10.00±3.35)/(8.64±3.52)、(31.50±10.76)]明显改善,差异有统计学意义(P〈0.05)。结论内囊前肢毁损术对难治性强迫症治疗有效,术后内囊前肢纤维束存在瘢痕修复,脑代�Objective To explore the curative effect of stereotactic bilateral anterior internal capsulotomy on refractory obsessive-compulsive disorder (OCD) and its safety and possible mechanism. Methods Retrospective analysis of clinical data of 14 patients with refractory OCD, admitted to and underwent anterior capsulotomy in our hospital from January 2009 and January 2014, was performed, including MR diffusion tensor imaging (MR-DTI), cerebral gluconate metabolism, obsessive-compulsive symptom and partial cognitive function evaluations before surgery, 3 and 6 months after surgery. Results MR-DTI showed that most of anterior limb fibers between the prefrontal lobe and striatum were damaged 3 months after the surgery, however, several fibers got repair under scar formation at 6 months follow-up. The metabolism in the orbital frontal cortex (right: 1.17±0.20, left: 1.20±0.06), ventromedial medial frontal cortex (right: 1.20±0.02, left: 1.18±0.07), striatum (right: 1.17±0.04, left:1.12±0.06), anterior cingulate (1.06±0.06) 6 months after capsulotomy was significantly decreased as compared with that before surgery (right: 1.41 ±0.19, left: 1.40±0.16; right: 1.26±0.02, left: 1.23 ±0.08; right: 1.35±0.10, left: 1.37±0.12; 1.23±0.07, P〈0.05), however, that in the occipital lobe (right: 1.58±0.14, left: 1.63±0.21) was significantly increased as compared with that before surgery (right: 1.39±0.14, left: 1.41±0.15, P〈 0.05). Yale-Brown obsessive compulsive scale, Hamilton anxiety scale and Hamilton depression scale scores 6 months after the surgery (9.00±4.94, 8.28±4.59 and 6.14±2.24) were significantly decreased as compared with those before surgery (29.21 ±5.36, 22.64±4.93 and 17.84±6.13, P〈0.05), while the post-surgery immediate/delayed logical memory scores (21.28±4.85, 18.00±5.39), immediate/delayed visual regeneration scores (13.00±1.51, 12.14±2.14) and block design test scores (39.83±6.80) were improved
