To describe a novel technique for ameliorating cerebrospinal fluid flow obstruction secondary to pia-arachnoid fibrosis in dogs and report outcome.
Descriptive report and retrospective case series.
Dogs with cerebrospinal fluid (CSF) flow obstruction (n = 7).
Medical records were searched for dogs that had a subarachnoid-subarachnoid shunt placed for treatment of CSF flow obstruction. Data collected included age, sex, breed, clinical signs and duration of signs prior to examination, neurologic status and localization prior to surgery, pre-surgical diagnostics, surgical technique, histopathology, postoperative neurologic examination, time to discharge from hospital, and outcome.
All dogs were diagnosed at surgery with a fibrotic adhesion between the arachnoid and pia mater. A subarachnoid shunting tube was implanted to allow CSF flow across the lesion site. Five dogs showed improvement of clinical signs, 3 of which showed complete recovery and 2 of which showed improvement without resolution of all clinical signs. Two dogs showed no change at 7 and 24 months postoperatively.
Bridging a region of pia-arachnoid fibrosis with a tube placed in the subarachnoid space can ameliorate or prevent progression of associated clinical signs.
描述一种改善犬软脑膜-蛛网膜纤维化继发脑脊液流动梗阻的新技术，并报告结果。
描述性报告和回顾性病例系列。
患有脑脊液（CSF）流动梗阻的犬（n = 7）。
检索病历，寻找因治疗脑脊液流动梗阻而进行蛛网膜下腔-蛛网膜下腔分流术的犬。收集的数据包括年龄、性别、品种、检查前的临床症状和症状持续时间、手术前的神经状态和定位、术前诊断、手术技术、组织病理学、术后神经检查、出院时间和结果。
所有犬在手术中均被诊断为蛛网膜和软脑膜之间存在纤维化粘连。植入蛛网膜下腔分流管以使脑脊液能够流过病变部位。5只犬的临床症状有所改善，其中3只完全恢复，2只虽有改善但并未消除所有临床症状。2只犬在术后7个月和24个月时无变化。
通过在蛛网膜下腔放置管子跨越软脑膜-蛛网膜纤维化区域，可以改善或防止相关临床症状的进展。
