A 6-year-old castrated male Shih-Tzu dog weighing 6. 5 kg presented with chief complaints of pollakiuria and urine dribbling. He had a history of urolithiasis for 3 years, which was confirmed by the presence of ammonium urate in the urinary stone analysis, performed 2 years prior to the presentation. Blood examination showed high values of fasting ammonia, post-prandial bile acid, and low blood urea nitrogen. Microhepatica and urolithiasis were identified on plain radiography and ultrasonography. A computed tomography angiography demonstrated a shunting vessel, diameter up to 9.6 mm, originated from the splenic vein, and linked with the phrenic vein. A surgical attenuation with a thin-film banding was performed under laparoscopic visualization. Left triangular ligament was incised, and one stay suture was placed to the stomach to expose the vessel. The shunting vessel was dissected before it entered the diaphragm, and a thin-film band was applied around the vessel. The patient recovered uneventfully without post-attenuation neurologic signs. Portal vein diameter increased with time, and complete closure of the shunting vessel was identified on computed tomography angiography performed at 14 months after attenuation. The patient was doing well for 31 months after surgery without protein restriction. This is a report of laparoscopic attenuation for splenophrenic type of canine congenital extrahepatic portosystemic shunt with a favorable outcome using thin-film banding.
Two Korean short-haired cats were admitted to the Veterinary Medical Teaching Hospital, Chonnam National University, with severe lower lip avulsion. In the first case, the treatment was performed using the tension-free suture technique with rubber tube stents. The second case was treated using the tension-free suture technique with rubber tube stents for lip avulsion and using the cerclage wiring technique for alveolar fracture. The teeth around the alveolar fracture were extracted and bone graft and collagen membrane were applied at the alveolar fracture site to stabilize the mandibular alveolar fracture. Thereafter, the cerclage wire was placed circumferentially around the mandible. In both cases, normal function of the oral cavity was successfully recovered by repairing the anatomic abnormality. In conclusion, tension-free suture technique can be a treatment option for bilateral lower lip avulsion in cats.
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.
