Raw Data for the article: Vascular Remodeling of Visceral Arteries Following Interruption of the Splenic Artery During Liver Transplantation

It was with great interest that we read the article by Patrono et al. and the comment by Dondossola et al., and we share the same interest in the splenic artery as a resource both for arterial inflow problems as well as for portal flow modulation. Portal hyperperfusion (PHP) is a well‐known condition where portal venous flow to the liver increases, and it is a characteristic for small‐for‐size syndrome in living donor liver transplantation. The consequences of PHP are hepatocyte morphological alteration, clinical symptoms, and, most importantly, pathophysiological changes in liver hemodynamics, such as for the hepatic arterial buffer response. Consistent hyperdynamic splanchnic circulation in patients with portal hypertension may cause excessive portal flow.

We here report the sequela of multidetector computed tomography (MDCT) scans of a patient who underwent liver transplantation (LT) with a whole liver in our unit and presented an unusual intraoperative finding of PHP.
