  • Often has a neuromuscular basis frequently secondary to Myasthenia gravis or idiopathic causes.
    • Congenital: More frequent in breeds like Schnauzers, Fox Terriers, Greyhounds, and German Shepherds.
  • Symptoms include severe regurgitation, weight loss, and the risk of aspiration pneumonia.

Diagnosis

  1. Radiographs: Show a dilated esophagus filled with air, indicating loss of motility.
  2. Fluoroscopy: Provides a functional assessment of esophageal motility.
  3. Acetylcholine Receptor Antibody Titers: Tests for Myasthenia gravis can be performed as diagnostic support.

Treatment

    • Consider supplementation with B vitamins to facilitate metabolic processes.

Portosystemic Shunt (PSS)

Etiology

  • Defined as an abnormal vascular connection between the portal and systemic circulations allowing blood to bypass the liver completely.
    • Intrahepatic shunts: occur within the liver, predominantly affecting large breed dogs (e.g., Wolfhounds, Old English).
    • Extrahepatic shunts: common in small breeds and cats (most frequently found in Yorkshire Terriers).

Pathophysiology

  • Blood returning from the gastrointestinal tract containing toxins bypasses liver filtration, resulting in systemic toxin accumulation, which raises the risk of hepatic encephalopathy due to elevated ammonia levels.
Symptoms
  • Symptoms often include neurological manifestations like ataxia, seizures, and general mental dullness, alongside gastrointestinal signs like vomiting, diarrhea, and weight loss. Additionally, urinary issues may arise due to the formation of struvite or ammonium birurate bladder stones.

Diagnosis

  1. Blood Panel: Indicators include low BUN, hypoalbuminemia, hypoglycemia, elevated ammonia levels, and liver enzyme markers (ALT/AST).
  2. Bile Acids Tests: Show increased values both pre and post-prandially.
  3. Radiographs: May demonstrate a small liver size.
  4. Ultrasound: Can confirm a vascular shunt.
  5. Nuclear Scintigraphy: Considered the definitive diagnostic test for identifying shunts through colorectal contrast agents.
  6. Portovenography: Used during surgeries to visualize the shunt directly.

Treatment

  1. Surgical Intervention:
    • Surgery involving an Ameroid constrictor over the vascular anomaly is the primary elective choice.
    • It necessitates partial ligation (70-80%), completely ligating the vessel may inadvertently induce portal hypertension.
    • Surgery is generally successful only for single extrahepatic shunts; though the prognosis is poor for intrahepatic or multiple shunts.
  2. Medical Management:
    • Aims to address hepatic encephalopathy through the reduction of ammonia.
    • Lactulose is vital for lowering ammonia levels.
    • Neomycin can limit ammonia-producing bacteria in gut flora.
    • Metronidazole may be utilized as another antibacterial option, along with retention enemas in cases of severe toxicity or coma.
  3. Prognosis: Generally favorable if an early diagnosis allows surgical correction of a single extrahepatic shunt.
