title: Outcomes of cats undergoing surgical attenuation of congenital extrahepatic portosystemic shunts through cellophane banding: 9 cases (2000-2007).
abstract: OBJECTIVE
  To evaluate the long-term prognosis of cats with a congenital extrahepatic portosystemic shunt (CEPSS) attenuated through gradual occlusion with cellophane banding (CB).
  
  
  METHODS
  Retrospective case series.
  
  
  METHODS
  9 cats with a CEPSS that was attenuated with CB.
  
  
  METHODS
  Medical records of cats surgically treated for CEPSS by means of CB from January 2000 through March 2007 were reviewed. Extracted data included preoperative clinical signs, medications, diagnostic results including serum bile acids concentrations, surgical technique, intraoperative and postoperative complications, and long-term follow-up information.
  
  
  RESULTS
  2 cats that developed refractory seizures were euthanized within 3 days after the CB procedure. Seven of the 9 cats survived to 15 days after surgery. Four cats did not have any clinical signs of CEPSS at long-term follow up. At that time, 5 cats had a postprandial SBA concentration within reference limits and 1 cat had persistent ptyalism. One cat had biurate ammonium stones removed > 2 years after surgery. One cat was euthanized 105 days after surgery because of uncontrolled seizures. The 3-year survival rate was 66%.
  
  
  CONCLUSIONS
  Uncontrolled seizure activity was the most common cause of death after CB. Long-term outcome for cats with CEPSS was fair to good after the procedure. Cats with a CEPSS surviving the immediate postoperative period had a fair to good long-term outcome. Cellophane banding without intraoperative attenuation appears to be an acceptable technique for gradual occlusion of a CEPSS in cats. Cats should be monitored closely for development of neurologic disorders in the postoperative period.
