Outcomes of cats undergoing surgical attenuation of congenital extrahepatic portosystemic shunts through cellophane banding: 9 cases (2000–2007)

Abstract

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.

Splenosystemic Shunts in Cats: A Retrospective of 33 Cases (2004–2011)

“…Splenorenal or splenocaval shunts have not been described in any of the published retrospective studies of congenital PSS in cats . The most common type of extrahepatic congenital PSS in cats involved the left gastric vein and the caudal vena cava.…”

“…Splenorenal or splenocaval shunts have not been described in any of the published retrospective studies of congenital PSS in cats. [1][2][3]6,[19][20][21] The most common type of extrahepatic congenital PSS in cats involved the left gastric vein and the caudal vena cava. The most common clinical signs reported in cats with congenital PSS (ptyalism, neurologic signs) were rarely reported in our study group.…”

“…P ortosystemic shunts are reportedly less common in cats than in dogs. [1][2][3][4][5][6] Congenital portosystemic shunts (PSS) are the most commonly identified PSS in cats and are the result of an anomalous embryonic vascular development and can occur without any identifiable underlying physical cause. 2 In contrast, acquired PSS develop in response to prehepatic or hepatic portal hypertension (PH).…”

In vitro development and evaluation of a polyacrylic acid–silicone device intended for gradual occlusion of portosystemic shunts in dogs and cats

“…9 Moreover, both types of gradual occlusion devices involve either an outer stainless steel ring or metal hemostatic clips, making postoperative confirmation of vessel closure via CT difficult. [15][16][17][18] The aforementioned limitations of ameroid ring constrictors and cellophane bands prompted the authors' goal of creating a gradual occlusion device that reliably closed via physical occlusion over 4 to 6 weeks, was devoid of metal to allow for postoperative imaging, was easily deployed and self-locking, and would also be able to be deployed via minimally invasive techniques. Gradual occlusion over 4 to 6 weeks has been suggested as an acceptable period to allow for adaptation of the portal system to the increased blood flow from shunt closure.…”

Anaesthesia and portosystemic shunt ligation in the feline patient

“…Cabassu et al (2011) explain that portosystemic shunts (PSSs) are anomalous vascular connections between the portal and systemic venous circulatory systems . Padgett (2002) suggests that this, therefore, allows portal blood draining the stomach, intestines, pancreas and spleen to deviate from the liver, causing cirrhosis, hepatic atrophy and encephalopathy …”
