“…Embryologically the primitive dorsal aortae has given a series of ventral splanchnic arteries for the primitive gut and its derivatives (Hamilton and Mossman, 1976). Most of these branches disappear normally, but persistence of normally disappearing branch/branches or abnormal fusion among these primitive arteries might explain the abnormal origin and course of the splenic artery.…”

Anatomical variations of the splenic artery and its clinical implications

The variations in orgin, course, and terminal branching pattern of the splenic artery were studied in 320 cadavers. The artery originated from the coeliac trunk in the majority of cadavers (90.6%), followed by abdominal aorta (8.1%), and other sights (1.3%). A suprapancreatic course of the artery was commonly observed (74.1%) followed by enteropancreatic (18.5%), intrapancreatic (4.6%), and retropancreatic (2.8%) courses. In two cases (0.63%) the proximal part of the splenic artery made a loop that was embedded in the substance of the pancreas, which is an interesting and rare finding. In five cases (1.5%) the proximal part of the artery divided into two or more branches that had suprapancreatic and enteropancreatic courses. The splenic artery divided into terminal branches in 311 (97%) cadavers. In nine (2.8%) cadavers it passed through the hilum of spleen without dividing. Two terminal branches were the most common (63.1%) followed by four (18.8%), six (9.7%), and more than six (5.6%) branches. The present study clearly indicates that there is variation in origin, course, and terminal distribution pattern of the splenic artery. The knowledge of these variations are of significant importance during surgical and radiological procedure of upper abdominal region to avoid any catastrophic complications.

“…The vascular anomalies are due to the aberration in the embryological development. Embryologically the splenic artery is one of the branches of the artery of foregut, i.e., coeliac trunk (Hamilton and Mossman, 1976). The splenic artery is remarkable for its tortuosity and because it is the largest branch of the coeliac trunk.…”

“…Nonetheless, the normal growth and differentiation of the human intrahepatic biliary system has not been systematically described. Controversies exist as to whether the bile ducts first mature adjacent to the porta hepatis (5,14,15) or, alternatively, at the periphery of the liver (16). It also remains unclear when in gestation interlobular bile duct development commences (7-9) and whether the epithelium of the interlobular bile duct originates from large bile ducts (14,16), hepatocytes (8,15,17) or a specialized anlage.…”

Paucity of interlobular bile ducts is a common feature of cholestatic liver disease in premature infants. Whereas a bile duct to portal space ratio of 0.9 to 1.8 is cited by Alagille as the norm for children, there are no data regarding the normal bile duct to portal space ratio in preterm infants. In this study, by examining liver tissue obtained from autopsied fetuses and infants, we have determined that the bile duct to portal space ratio increases as a function of postconceptional age. After 38 weeks postconception, a ratio equal to or greater than 0.9 was seen in eight of nine subjects. Therefore, in evaluating premature infants for duct paucity, liver biopsies should be obtained only after 38 weeks. Prior to 38 weeks postconception, a bile duct to portal space ratio less than 0.9 may be physiologic.

Introduction This study reports a case of two rare variations in the branching pattern of the splenic artery. Case report During the course of routine dissection of a 42-year-old male cadaver for teaching of preclinical medical students, we noticed two rare variations in the branching pattern of the splenic artery. The splenic artery was significantly non-tortuous; it was smaller (6 cm) in length. The splenic artery was seen to give a posterior gastric branch along with an accessory branch to the splenic flexure of the colon. Discussion The uniqueness of the current report lies in the fact that the splenic artery gave both the posterior gastric branch and an accessory branch to the left colic flexure. It is important for the surgeon to be aware of the existence of these variant branches of the splenic artery. These variations may be overlooked intraoperatively increasing the chances of inadvertent bleeding if damaged. Hence, their importance in abdominal surgical procedures especially, pancreatic transplant surgeries and left colonic resections cannot be overlooked. It is equally interesting to note that in this case; an artery of the foregut was seen supplying an area of the artery of the hindgut. This variation in the branching pattern of splenic artery can be correlated with its embryological development. Conclusion We as anatomists submit that awareness of variations of splenic artery as described in the current report would contribute to minimise vascular complications during abdominal surgeries.
