INTRODUCTION
Surgical intervention has been recommended for congenital portosystemic shunt in dogs, but acute complete ligation of shunt is associated with life- threatening portal hypertension. To reduce the risk
of portal hypertension, gradual vascular occlusion
is needed. The use of cellophane bands incites inflammatory reactions associated with a chronic foreign body and leads to gradual occlusion of shunted vessel.

INTRODUCTION
An 8-year-old intact male French bulldog was presented to necropsy at the Pathology Department of University of Veterinary Medicine, Budapest. It was a case of sudden collapse and death the day before presentation. There was no illness in the dog’s anamnesis.
OBJECTIVES
The necropsy was done to examine the cause of sudden death.
METHODS
During the necropsy, the following gross pathological lesions were seen. In the thoracic cavity we found 320 ml of mucinous red fluid and several gelatinous soft masses in connection with the pleura, pericardium and sternum. The lungs were collapsed due to the surrounding fluid. No other lesions were found in the body. Pieces of the masses were fixed in 8% neutral buffered formalin, and routinely processed and embedded in paraffin blocks. Sections of 3-4 μm thickness were obtained from the blocks and stained with haematoxylin and eosin (H.E.), periodic acid schiff (PAS), and later immunohistochemistry (IHC) was also performed.
RESULTS
With H.E. and PAS stainings we have seen several spindle-shaped cells in a myxoid stroma, surrounded by many small vessels. The cells were loosely arranged in the stroma. IHC staining with anti-Claudin-5, anti-α-SMA, anti-S-100, anti-CD31, anti-Ki-67 and anti-vimentin primary antibodies proved the diagnosis of angiomyxoma.
CONCLUSIONS
Angiomyxoma is a rare type of myxoid tumor in humans and animals. Only a few reported cases exist in veterinary medicine, none of them presented in the thoracic cavity. We report the first case of thoracic angiomyxoma as far as our best knowledge.
    OBJECTIVES
To report outcome after cellophane banding of single congenital portosystemic shunt in 4-month-old dog.
METHODS
On radiography, microhepatica with smooth margination was observed. On computed tomography, there was shunt vessel. from portal vein to CdVC. On laboratory test, serum ammonia level was 76μmol/L. ALP, AST, and GGT level was elevated and ALB, BUN, CREA level was decreased.
Based on these results, it was diagnosed as congenital portosystemic single shunt. As a treatment, surgical occlusion of shunt was performed followed 2 weeks medical management with hepatoprotective therapy, antibiotics and oral lactulose.
The patient had a ventral median celiotomy and surgical time was 50 minutes. Portosystemic shunt which entered CdVC from portal vein was identified by abdominal exploration. Cellophane bands was placed as reported previously. The patient was monitored intensively for 48 hours after surgery to observe for postligation neurologic dysfunction or portal hypertension.
RESULTS
Two weeks after surgery, neurologic dysfunction
of patient was recovered and postoperative serum ammonia concentration was decreased to 18μmol/L. There wasn’t complications associated with surgical shunt attenuation without recurrence of clinical signs.
CONCLUSIONS
Cellophane banding is a safe and effective alternative to ameroid constrictors methods of attenuation for large portosystemic shunt.
