Paraparesis and paraplegia are common conditions in dogs, most often caused by a disc herniation in the thoracolumbar spinal segments (T3-L3), which is a neurological emergency. Surgical decompression should be performed as soon as possible when spinal compression is revealed by myelography, computed tomography, or magnetic resonance imaging. Mesenchymal stem-cell therapy is a promising adjunct treatment for spinal cord injury. This study sought to compare the effects of surgical decompression alone and combined with an allogeneic transplantation of canine adipose tissue-derived mesenchymal stem cells (cAd-MSCs) in the treatment of dogs with acute paraplegia. Twenty-two adult dogs of different breeds with acute paraplegia resulting from a Hansen type I disc herniation in the thoracolumbar region (T3-L3) were evaluated using computed tomography. All dogs had grade IV or V lesions and underwent surgery within 7 days after symptom onset. They were randomly assigned into two groups, 11 dogs in each. The dogs in Group I underwent hemilaminectomy, and those in Group II underwent hemilaminectomy and cAd-MSC epidural transplantation. In both groups, all dogs with grade IV lesions recovered locomotion. The median locomotion recovery period was 7 days for Group II and 21 days for Group I, and this difference was statistically significant (p < 0.05). Moreover, the median length of hospitalization after the surgery was statistically different between the two groups (Group I, 4 days; Group II, 3 days; p < 0.05). There were no statistically significant between-group differences regarding the number of animals with grade IV or V lesions that recovered locomotion and nociception. In conclusion, compared with surgical decompression alone, the use of epidural cAd-MSC transplantation with surgical decompression may contribute to faster locomotor recovery in dogs with acute paraplegia and reduce the length of post-surgery hospitalization.

ResumoO shunt portossistêmico ou desvio portossistêmico (DPS) são comunicações vasculares únicas ou múltiplas entre a circulação sistêmica e a circulação portal, que permite que o sangue portal chegue ao sistema circulatório sem antes passar pela metabolização hepática. Podem ser adquiridos ou congênitos e também podem ser classificados como intra-hepático, localizado dentro do fígado, ou extra-hepático, localizado fora do parênquima hepático. A forma adquirida normalmente está associada com distúrbios intra-hepáticos. Eles normalmente sugerem vasos tortuosos que se comunicam com a veia cava caudal na região do rim esquerdo. A forma congênita está associada a genética e uma das linhagens mais acometidas é a raça maltês. O presente relato de caso descreve o diagnóstico e tratamento de uma cadela maltês de oito meses de idade com Shunt portossistêmico extra-hepático. A paciente apresentava sinais de encefalopatia hepática, como: inquietação, locomoção apoiando-se nas paredes, compressão da cabeça contra a parede, tremores de cabeça e deficiência visual. Exames complementares constataram: glicemia pós-prandial próximo do valor inferior de referência, fosfatase alcalina (FA) e alanina aminotransferase (ALT) aumentadas e hipoalbuminemia. A ultra-sonografia revelou a presença de cálculo vesical e cálculo renal bilateral, fígado diminuído e aumento da ecogenicidade, vesícula biliar com conteúdo anecóico e alta celularidade podendo sugerir hepatopatia/ colangiohepatopatia e detectou DPS extra-hepático. O uso do Doppler auxiliou na localização do desvio identificando a comunicação e a turbulência certificando-se do DPS extra-hepático. Dieta com restrição protéica e antibioticoterapia com amoxicilina obtiveram bons resultados. Optou-se em fazer apenas o tratamento clínico e manter a qualidade de vida da paciente. Palavras AbstractThe shunt portosystemic or portosystemic deviation (PSD) are unique or multiples vascular communications between the systemic circulaton and the portal circulation, that permit blood flow reaches the circulatory system without first passing trhought the hepatic metabolization. May be acquired or congenital and can also be classified as intrahepatic located within the liver or extrahepatic located outside the liver parenquima. The acquired form is usually associated with intra-hepatic disorders. They usually suggest tortuous vessels that communicate with the caudal vena cava in the region of the left kidney. The congenital form is associated with genetic lineage and one of the most affected is Maltese breed.
