Sažetak
A one year-old intact Great Dane female was presented with clinical signs of stunted growth, intermittent anorexia and vomiting, polyuria and mild neurological signs such as lethargy. The clinical signs were present for 7 months. Laboratory tests revealed a low urea serum concentration, as well as a mild hypoproteinemia and a mild hypoalbuminemia. Elevated preprandial and postprandial serum bile acid concentrations were also noted. A portosystemic shunt was suspected although not definitively confirmed by ultrasonography. An exploratory celiotomy was planned. Once the animal was anaesthetized, a central venous line was placed in the left jugular vein to assist with blood sample collection, fluid administration and for central venous pressure (CVP) measurement. A 7Fr, double lumen, wire-guided line (Seldinger technique) was aseptically placed and connected to the anaesthetic monitor via a pressure transducer chamber. Since the shunt was hard to locate due to severely changed anatomy of the abdominal vasculature, the CVP monitoring was used to detect the shunt by applying manual pressure for one minute onto the suspected shunting vein. This induced a drop in the CVP by 1 cmH20. With the release of the occluded vein, the CVP increased by 1cmH20. The procedure was repeated three times, to ensure the correct blood vessel is being occluded. A splenophrenic shunt was detected just caudal to the diaphragm and attenuated with celophane tape. The dog recovered quickly with all the clinical signs disappearing within two weeks of surgery. While the central line was originally placed for frequent blood sample collection for glucose monitoring and large volume administration, it was also helpful in locating the shunt due to CVP monitoring. The presented technique can be used to detect a portosystemic shunt when ultrasonography findings are inconclusive and a computed tomography scan is not available.
