Morphology of congenital portosystemic shunts emanating from the left gastric vein in dogsand cats

Authors


Abstract

Objective

To describe the anatomy of congenital portosystemic shunts emanating from the left gastric vein in dogs and cats.

Methods

A retrospective review of a consecutive series of dogs and cats managed for congenital portosystemic shunts.

Results

Forty-six dogs and 27 cats met the inclusion criteria of a congenital portosystemic shunt emanating from the left gastric vein. Of the 46 dogs, 28 (61%) had a shunt that entered the left phrenic vein, 10 (22%) had a shunt that entered the post hepatic caudal vena cava and in 8 (17%) the shunt entered the azygos vein. Of the 27 cats, 19 (70%) had a shunt that entered the left phrenic vein and 8 (30%) had a shunt that entered the post hepatic caudal vena cava.

Clinical Significance

The systemic vein into which the shunt entered was consistent showing three common presentations: left gastro-phrenic, left gastro-caval and left gastro-azygos. This information may help with surgical planning in cases undergoing shunt closure surgery.
