The objective of this study was to evaluate the clinical outcome of ventral slot decompression and rehabilitation therapy in dogs with cervical intervertebral disc herniation (IVDH). Surgical decompression was performed in dogs with IVDH using the ventral slot procedure. After surgery, physiotherapeutic rehabilitation consisted of a combination of electrotherapy, infrared therapy and mechanical massage; treadmill exercise was started when the animal could stand up. A total of 58 dogs were selected from the hospital and included in two groups: rehabilitated group (RG, n = 34) and non-rehabilitated group (NRG, n = 24). Dogs of each group were subdivided into five groups based on a pre-operative clinical grading system. Grade 1 designated spinal pain only, grade 2 designated ambulatory paraparesis, grade 3 designated non-ambulatory paraparesis, grade 4 designated paraplegia with deep-pain perception intact and grade 5 designated paraplegia without deep-pain perception. Post-operative changes of both groups were evaluated and compared, including time until unassisted standing and walking after surgery and the success rate. Overall, 79.41% (27/34) of dogs had a successful neurologic outcome in the RG group, which was significantly (P < 0.05) higher than the NRG group 62.50% (15/24). Interestingly, the success rate differed when the preoperative grading system was considered. The success rates of grades 1, 2, 3, 4 and 5 were 100% (9/9), 100% (7/7), 75% (3/4), 53.85% (7/13) and 100% (1/1), respectively, in the rehabilitated groups, whereas in the non-rehabilitated groups success rates were 100% (5/5), 83.33% (5/6), 60.00% (3/5), 28.57% (2/7) and 0% (0/1), respectively. The differences in success rates between the two groups according to grading were 0, 16.67, 15, 25.57 and 100%, respectively. The proposed rehabilitation therapy after surgical decompression of cervical IVDH can improve the success rate when the preoperative pathological condition is severe.
A 5-year-old, Yorkshire terrier was presented due to the acute onset of vomiting and diarrhoea. The imaging studies showed an abnormally separated gallbladder with a thickened wall, a tortuous common bile duct that contained hyperechoic materials. A cholecystectomy was performed because of the failure of the conservative management. The gallbladder was partially divided by a septum and communicated with the cystic duct. Histologically, the dog was diagnosed as having cholecystitis and choledochitis. To the author’s knowledge, this is the first clinical description of a symptomatic septate gallbladder in a dog. Although congenital gallbladder abnormalities are rare in animals, a septate gallbladder can predispose to an inflammatory biliary disease due to the abnormal bile flow.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
