In this study we described two different indications of ventriculo- and cystoperitoneal shunting (VPS, CPS) procedures in six dogs, including their clinical data and magnetic resonance imaging (MRI) examinations. One dog had moderate and two dogs had severe congenital hydrocephalus, one was presented with intracranial pressure elevation due to meningoencephalitis of unknown origin (MUO) associated with congenital hydrocephalus, and two with quadrigeminal cysts (QC). VPS procedures were done in four and CPS in two dogs, using low-pressure valve systems. The follow-up period ranged from 1 to 6 months and control MRI scans were also made. Significant improvement was detected in five cases during the short-term follow-up period (1 month) and in four cases in the medium-term follow-up (2-6 months). Major complications were found in two cases: one dog with acute-hypertensive hydrocephalus died one week after surgery, and in another case development of a chronic subdural haematoma and hygroma caused death 3 months after the surgery. Minor complications (e.g. subdural hygroma) were found in two cases. In cases of severe hydrocephalus or intracranial cysts, higher-pressure valve systems are recommended in order to prevent subdural hygroma. Transient postoperative clinical signs usually resolve within one week after the surgery.
在本研究中，我们描述了六只狗中两种不同的脑室-和囊腔分流术（VPS、CPS）的适应证，包括其临床数据和磁共振成像（MRI）检查。一只狗患有中度脑积水，两只狗患有重度先天性脑积水，一只因不明原因的伴发先天性脑积水的脑膜脑炎而出现颅内压升高，两只狗患有四叠体囊肿（QC）。四只用低压阀系统进行了 VPS 手术，两只用 CPS 手术。随访时间为 1 至 6 个月，并进行了对照 MRI 扫描。在短期随访（1 个月）期间，五例病例检测到明显改善，在中期随访（2-6 个月）期间，四例病例检测到明显改善。在两种情况下发现了严重并发症：一只患有急性高血压性脑积水的狗在手术后一周死亡，另一只狗在手术后 3 个月因慢性硬膜下血肿和硬膜下水肿导致死亡。两种情况下发现了轻微并发症（如硬膜下水肿）。在严重脑积水或颅内囊肿的情况下，建议使用高压阀系统以防止硬膜下水肿。术后短暂的临床症状通常在手术后一周内消退。
