Perfusion and functional anatomy of the splenic remnant supplied by short gastric vessels

Background: Surgeons have described many methods to preserve the injured spleen for the maintenance of host defence. The volume and the perfusion of remaining splenic tissue are important for better functional results. Imaging the functioning tissue with radionuclide provides information about the p...

Description
Summary:Background: Surgeons have described many methods to preserve the injured spleen for the maintenance of host defence. The volume and the perfusion of remaining splenic tissue are important for better functional results. Imaging the functioning tissue with radionuclide provides information about the physiology of the concerning organ. Methods: Thirty rats were separated into three groups: control, explorative laparotomy alone; partial splenectomy, upper part of the spleen supplied by short gastric vessels was preserved after partial resection; and devascularized spleen, the entire spleen was preserved after ligation of splenic artery. The size, functional anatomy, and perfusion status of splenic tissue were assessed by liver-spleen scintigraphy using radiolabeled heat denatured red blood cells. Results: In the partial splenectomy group, splenic radioactivity count, spleen/liver ratio, and radionuclide uptake were mildly reduced, and found to be 87% ( P = 0.012), 91% ( P = 0.16), and 88% ( P
