[Anatomical and surgical considerations concerning the segmentation of the pancreas].

Pancreatic vascularization, especially the right segment (the head of the pancreas) has great surgical importance, due to its anatomical variety. From this practical point of view, establishing the type of the patient's pancreatic vascular pattern is highly recommended not just diagnosis purposes, but especially for its indispensable role in surgical decision. Selecting the appropriate technique, based on the imagistic evidences must consider the anatomical studies, which propose a systematic vision of the cephalic area vascularization, detecting two major types of arterial distribution. The first type is especially anastomotic; meanwhile the second one is terminal, these two varieties leading to a different surgical technique, best adapted for avoiding hemorrhages or ischemic necroses. Between the classic two segments of the pancreas (cephalic and caudal parts) there is a less vascularized area, which includes just an intersegmentary artery and the pancreatic duct, surgically sectioned during the separation operation of the two pancreatic segments. Vascular variety of the pancreas may be related to both embryological development of the pancreatic tissue, and that of the abdominal aortic branches.
