Plain-English summary
A dog with an intrahepatic portosystemic shunt (a type of blood vessel problem in the liver) underwent surgery to fix the issue. During the operation, the vet used special imaging techniques and an ultrasonic tool to help locate and isolate the shunt more easily. This approach not only made it easier to find the problem but also reduced the time needed for surgery and minimized bleeding. After the shunt was successfully ligated (tied off), the dog's liver showed normal blood flow on the imaging, indicating a successful outcome.

Abstract
Mesenteric portography, using a C-arm fluoroscope equipped with digital subtraction capability, was performed intraoperatively to locate a single, intrahepatic portocaval shunt. An ultrasonic aspirator was used to isolate the shunt, which was ligated completely. Typical portal venous arborization was seen on postligation intraoperative mesenteric portography. Subtraction angiography used intraoperatively and dissection with the ultrasonic aspirator improve the surgeon's ability to localize and isolate intrahepatic portocaval shunts and can reduce surgical time. Film development and patient repositioning and transport, before and after shunt ligation, are not necessary when mesenteric portography is performed intraoperatively, using a C-arm fluoroscope and digital subtraction. Dissection around intrahepatic portocaval shunts is facilitated by the ultrasonic aspirator, which selectively fractures and suctions tissue from around the shunt. Hemorrhage is decreased, because hepatic ductules and small blood vessels are left intact.
