To evaluate lack of encephalopathy as a positive prognostic factor for complete ligation of extrahepatic congenital portosystemic shunts in dogs.
Retrospective analysis of case records.
Dogs with extrahepatic congenital portosystemic shunts treated at the Veterinary Medical Teaching Hospital of the College of Veterinary Medicine, Cornell University, from 1985 to 1996.
The ability to completely ligate the shunting vessel in 12 nonencephalopathic dogs was compared with that in 44 encephalopathic dogs with similar shunts.
Clinical signs in the 12 nonencephalopathic dogs were related to ammonium biurate urolithiasis. All 12 dogs had single extrahepatic shunting vessels. The rate of complete ligation in the nonencephalopathic dogs was 92%, whereas the rate of complete ligation in the 44 encephalopathic dogs with single extrahepatic shunts was 59%. The ability to completely ligate the shunt in nonencephalopathic dogs was significantly better (P = .04) than in the encephalopathic dogs.
Lack of encephalopathy is a positive prognostic factor for complete ligation of single extrahepatic congenital portosystemic shunts.
In most affected dogs, extrahepatic congenital portosystemic shunts in nonencephalopathic dogs can be completely ligated.
评估无肝性脑病作为犬肝外先天性门体分流完全结扎术预后良好因素的作用。
病例记录回顾性分析。
1985年至1996年在康奈尔大学兽医学院兽医教学医院接受治疗的患有肝外先天性门体分流的犬。
比较12只无肝性脑病犬与44只患有类似分流的肝性脑病犬完全结扎分流血管的能力。
12只无肝性脑病犬的临床症状与尿酸铵尿石症有关。所有12只犬均有单一肝外分流血管。无肝性脑病犬的完全结扎率为92%，而44只患有单一肝外分流的肝性脑病犬的完全结扎率为59%。无肝性脑病犬完全结扎分流的能力明显优于肝性脑病犬（P = .04）。
无肝性脑病是单一肝外先天性门体分流完全结扎术预后良好的因素。
在大多数患病犬中，无肝性脑病犬的肝外先天性门体分流可完全结扎。
