title: Clinical anatomy of the caudal pancreatic arteries and their relevance in the surgery of the splenic trauma.
abstract: Splenectomy is the treatment of splenic trauma but is not exempt from intra-operative and post-operative complications. Conservative approach is preferred for paediatric population and for minor trauma. The aim of the present study was to evaluate the vascularisation of the tail of the pancreas, with particular reference to the presence of anastomosis between the pancreatic and splenic vessels, through an anatomoradiologic study performed on 9 unembalmed cadavers (age range 44-77 years). To obtain vascular corrosion casts, the splenic, the gastroduodenal and the superior mesenteric arteries were injected with acrylic and radioopaque resins and computed tomography (CT) of the specimens were acquired. The caudal pancreatic arteries (mean number ± standard deviation: 3.2 ± 2.4) were observable in all the casts, originating from the splenic artery at its distal third (70%) and from its inferior branch (30%). At CT scans analysis the mean calibre of caudal pancreatic arteries was 2.1 ± 1.1 mm. Anastomosis were found with great pancreatic artery in 20%, and with hilar splenic artery in 80%. The pattern of anastomosis between the pancreas tail and the spleen could allow the surgeon to close the splenic artery at the origin and also the short gastric and the left gastroepiploic arteries, in cases of splenic trauma, favouring the hemostasis and allowing splenic preservation at a same time.
