“…Its observed prevalence in humans varies with the method employed for its detection. In anatomic series it varies from 4 to 99% [31]. In angiographic studies its prevalence is lower on average, from 36.8 according to Kupic et al [13] to 46% as reported by Di Dio et al [5].…”

“…First described by Walther in 1729 [36] and so called by Haller in 1745 [9,31], it arises from the splenic a. trunk. Its observed prevalence in humans varies with the method employed for its detection.…”

“…This variation can be interpreted as a reflection of radiologic misinterpretations due to image superimposition or to complete obliteration of its ostium due to atherosclerosis. The variability among different authors can also be explained on a different basis: variable prevalence, misunderstandings in nomenclature, and different detection methods such as angiography, injection-corrosion casts and cadaver [5,31,32]. Moreover, it has been detected intraoperatively (84%) by the injection of methyleneblue into the splenic a.…”

“…It arises from the proximal third of the splenic a. in 18.4% of cases, from the middle third in 47.8% and from the distal third in 34.2% [291. It is often difficult to distinguish this vessel from the accessory left gastric a.; but, when the area supplied is the body-fundus of the stomach [31], it seems correct to label this vessel as the posterior gastric a. or <~ramus esophagogastricus ascendens posteriors> according to the nomenclature suggested by the Japanese Research Society for Gastric Cancer (JRSGC) [12]. On the other hand, when it arises from the proximal third of the splenic a. and supplies the lesser curvature (anterior and posterior wall) and the abdominal esophagus, it seems more correct to label it as the accessory left gastric a.…”

Arterial vasculature of the stomach and oncologic gastrectomies

Preoperative knowledge of the gastric arterial blood-supply with special regard to anatomic anomalies is desirable for a correct surgical approach to this viscus and for the reduction of intra- and postoperative complication rates. The authors report their experience with the use of preoperative digital angiography in the evaluation of 46 consecutive patients undergoing gastric cancer surgery. Twenty of these (43.5%) presented a vascular anatomy different from the normal pattern. In 6 (13%), a double arterial anomaly was detected. Some anatomic anomalies of the celiac axis and superior mesenteric artery are described in relation to operative procedures during oncologic gastrectomies.

The posterior gastric artery: A meta‐analysis and systematic review

et al. 2023

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.

The clinical anatomy of the posterior gastric artery revisited

et al. 2007

A consensus concerning the incidence, course and distribution of the posterior gastric artery (PGA) has yet to be reached. Recent literature has explored and subsequently demonstrated the importance of the identification of this vessel in surgical procedures such as subtotal gastrectomy, splenectomy and pancreatic transplantation. The gross anatomy of the PGA was examined in 120 adult human cadavers. The PGA was identified as that artery which provided the predominant arterial supply to the posterior wall of the superior portion of the gastric body near the cardiac region and fundus. A PGA was identified in 81.6% of specimens. The most common origin of the PGA was from the left gastric artery (type I), occurring in 41.8% of specimens. In decreasing order of prevalence, were origins from the splenic artery (Type II), occurring in 25.5%; from both the left gastric and splenic arteries as double PGAs (Type III) in 22.4%; and from the celiac trunk (Type IV) occurring in 10.2%. The importance of accurate delineation of the PGA is crucial for pancreatic transplantation and gastric tumor removal. In addition, knowledge of variations in this vessel's origin could prove useful in transcatheter arterial embolization for the treatment of chronic bleeding from gastric ulcers. Furthermore, ligation of this vessel during partial gastrectomy, pancreaticoduodenectomy, and parietal cell vagotomy may result in gastric wall necrosis and gastric stump leak.
