The angiographic visualization of the pancreatic arteries, their numerical variations, origins, course and anastomoses, as well as their mean diameter by age-group (20–40, 41–60, 60 years) have been quantitatively investigated by selective celiac angiography in 72 patients without pancreatic disease. Visualization of the various arteries was achieved in a high percentage of cases except for the inferior pancreaticoduodenal arches, due to undervaluation of this vessel by celiac angiography.
Confirmation of the great variability of the origin and anastomoses of the dorsal and transverse pancreatic arteries was obtained and possible embryologic reasons and clinical implications of this fact are discussed. Furthermore, a high percentage of multiple (quadruple or more) pancreatica magna and caudae pancreatis arteries has been observed and a functional role of this peculiar arrangement is suggested, Finally, no statistically significant differences were found in the diameter of any artery due to increasing age probably reflecting maintained neural perivascular control of the pancreatic vessels in the elderly. Satisfactory sensitivity of the angiographic method has been found with respect to the evaluation of visualization and anastomoses of the pancreatic arteries in vivo.

We present a case of primary emphysematous pancreatitis caused by Clostridium perfringensinfection (also known as spontaneous pancreatic gas gangrene) in a 66-year-old man with diabetes and a history of recurrent pancreatitis.One notable feature is the absence of a focal distribution, which is seen on radiological studies to be accompanied by extensive retropneumoperitoneum, with dissemination of the gas toward the mesenteric root and pelvic extraperitoneal spaces. This wide diffusion is aided by the C.

Perfringens toxins and the pancreatic enzymes released, leading to a fulminant course, an elevated rate of early mortality among the cases reviewed. The early diagnosis of this disease is fundamental, enabling aggressive medical treatment and emergency surgery.Diabetes is a known risk factor for anaerobic infection, including C. Perfringens, as in the case of emphysematous cholecystitis.A diseased pancreas or pancreatic duct facilitates the development of infections since it eliminates poorly the microorganisms that reach it from the duodenum.Gas gangrene secondary to necrosis-related superinfection or pancreatic collections is uncommon, and spontaneous or primary cases are exceptionally rare.
