Surgical Management of Left‐Divisional Intrahepatic Portosystemic Shunts: Outcome After Partial Ligation of, or Ameroid Ring Constrictor Placement on, the Left Hepatic Vein in Twenty‐Eight Dogs (1995–2005)

Abstract

Based on these data, ARC placement on the left hepatic vein in dogs with left-divisional intrahepatic PSS cannot be recommended.

Outcomes of cellophane banding or percutaneous transvenous coil embolization of canine intrahepatic portosystemic shunts

“…This may reflect the fact that both procedures seek to attenuate the IHPSS and redirect portal blood back to the deprived liver, albeit by different mechanisms. Survival times reported here are consistent and/or improved from previous reports . However, the interpretation of our survival analysis warrants caution due to loss and/or lack of follow up in some of our dogs.…”

“…Hepatic insufficiency can cause a myriad of clinical signs, such as seizures, ataxia, obtundation, anorexia, vomiting, diarrhea, pollakiuria, stranguria, and death . The severity of these signs justifies surgical correction aimed at improving the perfusion of the deprived liver . Surgical techniques are generally classified as extravascular or intravascular and achieve partial or complete attenuation.…”

“…Surgical techniques are generally classified as extravascular or intravascular and achieve partial or complete attenuation. Complete occlusion of CIHPSS is rarely feasible without inducing unacceptable portal hypertension; instead, partial or gradual occlusion techniques have been applied most frequently . Extravascular partial suture ligation was reported most commonly in the veterinary literature through the turn of the 20th century .…”

Health‐related quality of life following surgical attenuation of congenital portosystemic shunts versus healthy controls

“…, Mehl et al . , Falls et al . ), but few studies compare techniques, resulting in a lack of evidence to recommend one treatment over another (Tivers et al .…”

Liver

“…Ultrasound-guided transsplenic injection of agitated saline has been used to evaluate the intravascular transit of microbubbles through the portal system in normal dogs. 286,290,[306][307][308][309][310][311][312] Ultrasonography has been used to diagnose the shunt, aid ligation or placement of devices, and assess outcome of treatment. 305 Transvenous coil embolization, surgical ligation, and placement of other external occlusion devices have been used to treat congenital intrahepatic or solitary extrahepatic portacaval shunts in dogs.…”
