“…A short‐term postoperative mortality rate of 3%–9% with gradual attenuation with a CB has been identified in previous studies, comparable to the short‐term postoperative mortality rate of 10.4% observed in our cohort of dogs that underwent gradual attenuation with TFB . In comparison, a postoperative mortality rate associated with ARC placement between 0% and 7% has been determined in several studies . A recent report described a postoperative mortality rate of 4.3% after ARC placement in a cohort of 49 dogs .…”

Objective To compare long‐term clinical outcomes of dogs with single congenital extrahepatic portosystemic shunts (CEHPSS) treated with thin film banding (TFB) consisting of polyolefin fiber or ameroid ring constrictor (ARC) placement in dogs. Design Retrospective, two‐center clinical study. Animals Client‐owned dogs (n = 123) with single CEHPSS undergoing gradual attenuation via TFB (n = 85) or ARC (n = 38). Methods Medical records of dogs with CEHPSS were reviewed. Follow‐up data were collected from the referring veterinarian and/or owner via standardized questionnaire. Data were analyzed to compare short‐term mortality rate and long‐term outcome (>6 months). Results Dogs in the TFB group were older than dogs in the ARC group (median age, 19 vs 12 months, respectively; P = .01). There was no difference in survival to discharge between dogs in the TFB (81/85 [95.3%]) and ARC (37/38 [97.4%]; P > .99) groups. Preoperative levetiracetam was more frequently administered to dogs treated with TFB (64/85 [75.3%]) than to dogs treated with ARC (15/38 [39.5%;] P = .0002). Postoperative seizures were reported in 10 (8.1%) dogs; their prevalence did not differ between dogs treated with TFB (9/85 [10.6%]) and dogs treated with ARC (1/38 [2.6%]; P = .17). Median follow‐up time for dogs treated with TFB (58.0 months, range 8‐130) and ARC (63.3 months, range 7‐138; P = .24) did not differ. Conclusion Gradual attenuation of a single CEHPSS with either TFB or ARC resulted in similar long‐term clinical outcomes and low postoperative morbidity and mortality rates. Clinical significance Thin film banding (polyolefin fiber) offers an alternative leading to clinical outcomes similar to ARC in dogs with single CEHPSS.

“…The present study did not include any form of postoperative imaging to determine CEHPSS attenuation; however, it is likely that, at less than 20 days postoperatively, minimal shunt attenuation would have occurred. Previous studies have typically performed repeat imaging at >1 month postoperatively …”

Objectives To design a health‐related quality of life questionnaire for dogs with congenital portosystemic shunts, use it in a cohort of dogs treated with suture attenuation and compare results with those obtained from a healthy control cohort. Materials and Methods Data were collected from the hospital records of dogs treated with suture ligation of an intrahepatic or extrahepatic congenital portosystemic shunt at two referral centres. Owners were asked to complete a questionnaire assessing their dog's health‐related quality of life preoperatively (retrospectively) and at the time of follow‐up. Owners of control dogs also completed the questionnaire. Results One hundred and twenty‐eight dogs with congenital portosystemic shunts and 131 control dogs were recruited. Median follow‐up time was 64 months (range 19.7 to 157.2). The median long‐term health‐related quality of life score was excellent for both intrahepatic and extrahpatic shunt cases and similar to that of control dogs. The long‐term portosystemic shunt clinical sign scores for both intrahepatic and extrahepatic congenital portosystemic shunt dogs were significantly worse than the those of the control group. Clinical Significance Suture attenuation of congenitial portosystemic shunts is associated with an excellent health‐related quality of life score at long‐term follow‐up.
