摘要:

文题释义:
腰椎间盘切除手术:是指通过手术方式直接摘除突出的髓核组织,扩大神经根管以解除压迫,达到治疗腰椎间盘突出症的目的,手术方式包括微创手术和传统开放手术。
症状性椎间盘假性囊肿:是椎间盘手术区域出现的囊性病变,压迫神经根后常导致术前症状复发甚至加重,其形态和影像学表现与椎间盘囊肿类似,均为椎间盘表面形成的囊性肿块。

背景:术后症状性椎间盘假性囊肿是椎间盘手术区域出现的囊性病变,一般在患者术后早期进行MRI检查时发现,目前关于其临床特点和发病机制的资料不足,其治疗方法仍存在争议。
目的:探讨椎间盘切除后并发症状性椎间盘假性囊肿的临床特点、发病机制和治疗策略。
方法:纳入2019年1月至2021年9月在重庆医科大学附属永川医院行椎间盘切除后并发症状性椎间盘假性囊肿患者7例,男5例,女2例,年龄35-60岁,回顾性分析其临床特点与治疗方法。
结果与结论:①7例患者中,5例行经皮内镜腰椎间盘切除手术,2例行显微内镜椎间盘切除手术,术后患者腰腿痛症状均得到明显缓解。但术后症状均再次发作,术后MRI发现原手术区域T1加权像低信号,T2加权像呈高信号,并与椎间盘内相通,确诊为症状性椎间盘假性囊肿,MRI发现平均时间为椎间盘切除后32 d;②对于7例症状性椎间盘假性囊肿患者,4例给予止痛消肿、卧床休息等对症处理,1例行经皮内镜腰椎间盘切除手术,2例行显微内镜椎间盘切除手术,患者术后腰腿疼痛症状均得到明显缓解;术后1个月随访,MRI示原假性囊肿明显缩小;③结果提示,症状性椎间盘假性囊肿常见于椎间盘切除后早期,MRI可作为首选检查,当保守治疗无效时可行介入或者手术治疗,预后均较好。

Abstract: BACKGROUND: Postoperative symptomatic intervertebral disc pseudocyst is a cystic lesion in the area of intervertebral disc surgery. It is usually found in patients undergoing MRI examination in the early postoperative period. At present, there is insufficient data on its clinical characteristics and pathogenesis, and its treatment method is still controversial. 
OBJECTIVE: To investigate the clinical characteristics, pathogenesis and treatment strategy of symptomatic intervertebral disc pseudocyst after discectomy.
METHODS:  Seven patients with symptomatic intervertebral disc pseudocysts after intervertebral discectomy in the Yongchuan Hospital Affiliated to Chongqing Medical University from January 2019 to September 2021 were enrolled in this study. There were 5 males and 2 females, at the age of 35-60 years. Clinical features and treatments were retrospectively analyzed.
RESULTS AND CONCLUSION: (1) Among seven patients, five patients underwent percutaneous endoscopic lumbar discectomy and two underwent posterior microscopic endoscopic discectomy. Their symptoms were significantly relieved after surgery. However, the symptoms recurred after the operation. The postoperative MRI showed low signal on T1WI and high signal on T2WI in the original operation area, and it communicated with the intervertebral disc, which was diagnosed as symptomatic intervertebral disc pseudocyst. The average time for MRI to find the pseudocyst was about 32 days. (2) For seven patients with symptomatic intervertebral disc pseudocysts, four patients received analgesia and detumescence, bed rest and other symptomatic treatments; one patient received percutaneous endoscopic lumbar discectomy; two patients received microscopic endoscopic discectomy. Waist and leg pains were significantly relieved. At 1 month after operation, MRI showed the original pseudocyst was significantly reduced. (3) The results indicate that symptomatic intervertebral disc pseudocyst usually occurs in the early postoperative period. MRI can be the first choice for examination. When conservative treatment fails, interventional or surgical treatment can be performed and the outcome can be good.
