Abstract：
OBJECTIVE: To study patients with spinal arachnoid cysts, who underwent cyst excision with dural defect repair or marsupialization, and their outcomes.
METHODS: The retrospective analysis involved reviewing the records of 38 patients who underwent surgical treatment for spinal arachnoid cysts in the Department of Neurosurgery at Christian Medical College, Vellore, between August 2004 and December 2022. The study examined the demographics, clinical presentation, imaging, surgical intervention, and outcomes of these patients.
RESULTS: The majority of patients in the study were male (29/38, with 76.3%) and the thoracic region was the most common location for the cyst (17, with 44.7%). Weakness was the primary complaint and 94.7% of patients had myelopathy. The bladder was affected in 13 patients (34.2%). Of the 38 patients, 26 (71%) had cysts in extradural locations, while the rest were intradural. In total, 45.5% of intradural cysts were located in the ventral region. Seventeen (65.4%) had dural defects along the root sleeve and 29 (76.3%) underwent complete excision. All extradural cysts underwent complete excision and repair of the dural defect. Thirty patients (78.9%) experienced improved outcomes with reduced spasticity and improved weakness. One patient developed new-onset weakness postoperatively due to epidural hematoma. The mean follow-up period was 41 months and one patient experienced a recurrence.
CONCLUSIONS: Spinal arachnoid cyst is a rare benign spinal condition that is typically treated with surgery in symptomatic patients. Surgical intervention may involve either the excision of the cyst or marsupialization.

摘要：
目的：研究接受囊肿切除伴硬膜缺损修复或袋袋化的脊髓蛛网膜囊肿患者，和他们的结果。
方法：回顾性分析包括回顾在基督教医学院神经外科接受脊髓蛛网膜囊肿手术治疗的38例患者的记录，Vellore,2004年8月至2022年12月。这项研究检查了人口统计学，临床表现,成像,手术干预,以及这些患者的结果。
结果：研究中的大多数患者为男性（29/38，占76.3％），囊肿的最常见部位为胸腔（17例，占44.7％）。弱点是主要的抱怨，94.7%的患者患有脊髓病。13例（34.2％）膀胱受累。在38名患者中，26（71％）在硬膜外位置有囊肿，其余的都是硬膜内的.总的来说,45.5%的硬膜内囊肿位于腹侧区域。17例(65.4%)沿根套有硬脑膜缺损，29例(76.3%)接受了完全切除。所有硬膜外囊肿均接受了硬膜缺损的完整切除和修复。30例（78.9%）患者的预后得到改善，痉挛减少，弱点改善。一名患者因硬膜外血肿术后出现新发无力。平均随访时间为41个月,一个病人复发了.
结论：脊髓蛛网膜囊肿是一种罕见的良性脊柱疾病，通常对有症状的患者进行手术治疗。手术干预可能涉及囊肿切除或袋袋化。
