“…Overlooking the PGA during pancreas harvesting can lead to significant bleeding and its treatment to damage the vascular supply and loss of the graft. Troppman et al reported a case where overlooking the PGA lead to a splenic artery injury during procurement (Troppmann et al, 2004).…”

The aim of this study was to review the literature on the posterior gastric artery, estimate its prevalence and summarize its reported origins. The databases Pubmed, Scopus, Web of Science and Google Scholar were searched to find all studies describing the prevalence and origin of the posterior gastric artery. Pooled prevalences were estimated using a random effects model. Thirty‐eight studies with a total of 3366 subjects were included in the analysis. The overall prevalence of the posterior gastric artery was 57.4% (95% CI = 49.1%–65.7%). The prevalence of the posterior gastric artery was significantly higher in surgical studies than in cadaveric and angiographic studies. There were no differences in prevalence between multi‐detector computed tomography studies and cadaveric studies, nor were there differences when comparing geographical location or study size. Origin data were extracted from 34 studies, with a total of 1533 cases. The posterior gastric artery arose as a single vessel from the splenic artery in 1160 cases (pooled prevalence 86.5% [95% CI = 78.5%–94.7%]), from the superior polar splenic artery in 339 cases (pooled prevalence 11.8% [95% CI = 3.7%–19.9%]) and from other origins in 50 cases (pooled prevalence 0.27% [95% CI = 0.00–0.71%]). The posterior gastric artery is present in 57.4% of cases and most commonly arises from the splenic artery. It should be identified before gastric resections as it may be an important source of blood to the gastric stump. Multi‐detector computed tomography has sufficient sensitivity to detect it before surgery.

“…Although investigated and depicted in many anatomical studies, a consensus regarding the incidence, course and distribution of PGA is not yet reached 4 . Many variations in the course and branching patterns of splenic artery are mentioned in the literature [5][6][7][8][9] . However, a branch of the splenic artery to colon is rare 10,11 .…”

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.
