Three minimally invasive methods of measuring of portal vein pressure in healthy dogs

Abstract

We compared wedged hepatic venous pressure (WHVP), splenic pulp pressure (SPP) and trans-splenic portal vein pressure (TSPVP) in healthy dogs. We found that portal blood pressure could be measured in dogs using any of these techniques. The WHVP, SPP and TSPVP were 7.8 ± 1.0, 6.2 ± 0.8 and 6.8 ± 1.2 mmHg, respectively. Measuring SPP using ultrasound is most simple and minimally invasive, and it might be useful for evaluating portal hypertension in dogs with liver diseases. © 2012 The Japanese Society of Veterinary Science.
