Abstract

The aim of the study was to assess the prepubic minilaparotomy approach in the surgical treatment of prostatic disorders in dogs. The technique of a limited approach to the prostate was developed on the fresh cadavers of 14 intact adult male dogs, diversified in regard to size and body weight. The abdominal cavity was opened in midline, from the right-sided prepubic parapenile incision. The cut was limited to 7 cm. Afterwards, it was expanded by self-retaining retractors: Gelpi, Weislander, Finnochetto Baby, and Adson. Finnochetto Baby and Gelpi retractors used in pairs enabled an adequate exposition of the prostate in small dogs. The Finnochetto Baby retractor enabled an adequate exposition of the prostate in medium dogs and the Adson retractor - in large and giant dogs. The Weislander and Gelpi retractors used individually did not allow for sufficient access to the prostate in any group of the cadavers. Prepubic minilaparotomy can be a useful surgical approach in the treatment of prostate disorders in dogs. It can be used especially for minor surgical procedures, e.g. sampling of large tissue specimens for histopathological examination, partial prostatectomy, or treatment of intraparenchymal cavitary lesions.

Abstract

The operational method (V-cut pelvic ostectomy) was applied on seven dogs. Pubic symphysis was cut in an inverted “V” fashion and a bone gap occurred between pelvic halves. The gap was reduced by contracting both sides of the pelvis. A new pubic symphysis developed. Results were evaluated with radiographs and different clinical and orthopedic tests. Radiographic measures between mutual parts of pelvic bone showed a marked increase in Norberg angles and diminishing in Bardens, Barlow, and Ortolani orthopedic tests after operations. Principal conclusion: V-cut pelvic ostectomy was found to be a successful operation technique in treatment of canine hip dysplasia.

Abstract

Introduction: The clinical symptoms of portosystemic shunts (PSSs) and hepatic microvascular dysplasia (HMD) – portal vein hypoplasia (PVH) in dogs are similar. PSSs are abnormal vascular connections between the portal vein system and systemic veins. HMD is a very rare developmental vascular anomaly, recognisable during histopathological examination. The study aim was to assess the prevalence of HMD–PVH and hepatocellular and vascular pathologies in the liver. Material and Methods: Liver biopsies from 140 dogs (of different breeds and both sexes) arousing clinical suspicion of PSS were examined histopathologically. Results: An initial PSS diagnosis was confirmed in 125 dogs (89.29%). HMD–PVH was found in 12.32% of dogs, as an isolated disease in 9.29%, especially in Yorkshire terriers, and with extrahepatic PSS in 6.67%. Histopathological analysis of muscles around sublobular veins showed that HMD cases presented hypertrophy or hypertrophy with fibrosis. In 2.17% of all dogs with liver vascular developmental disorders calcification was visible around vessels (without correlation by degenerative changes in those vessels), suggesting prior onset of deep metabolic disorders. Clinical suspicion of PSS was also formed upon quite different pathological processes in young dogs. Conclusion: Histopathological findings diagnosed the type of vascular anomalies (PSS or HMD–PVH) or other pathological changes conclusively, therefore detailed hepatic histopathology is an indispensable component of the clinical diagnostic process.
