“…5b). The origins of subphrenic arteries from the aorta can be identified angiographically in 17–47% of cases, and in 1.3–10.6% of right and left IPhA, branching from LGA 16,24,29 (Fig. 5b).…”

“…Also short gastric vessels, or the superior splenic artery must be preserved. Identification of such vessels by intraoperative intra‐arterial injection of vital dye is helpful in avoiding ischemic gastric wall necrosis 1,5,29 . Middle gastric tumor localization demands dissection of all lymph nodes along the splenic artery, where both branches must be preserved for the prevention of partial splenic necrosis 23,29,30 .…”

The surgeon's ability to recognize abnormal vascular anatomy has greater importance than ever in modern esophagogastric surgical procedures. Some aberrations of vascular vessels around the stomach found during extensive surgery due to primary cancer of the stomach, cardia and lower esophagus are presented in this paper. The purpose of the prospective study is to evaluate and classify these variations with respect to their impact in visceral surgery. A total of 426 patients who underwent total or extensive gastrectomy and esophagectomy combined with lymphadenectomy, have been analyzed prospectively. For the period of 10 years some vascular aberrations have been found in 54/426 (12.67%) of the patients in the operative field during lymphadenectomy as single or combined anomalies. An arterial perigastric anatomy considered normal in textbooks was found in 372 (87.32%) cases. An accessory left hepatic artery arising from the left gastric artery was found in 19/54 (35.18%), and replaced type in 7/54 (12.96%). The replaced right hepatic artery branching from the superior mesenteric artery was found in 5/54 (7.40%) cases. Replaced and accessory left gastric artery branching from the aorta was found in 8/54 (14.8%); accessory posterior gastric artery was found in 25/54 (44.4%), and abnormalities of the splenic, and subphrenic arteries were found in 6/54 (11.11%). Combined anomalies of both left and right hepatic arteries and variations of the celiac trunk were found in 2/54 (3.70%) cases. Forty-nine cases were classified according to established Michels' typology system. Six cases presented with extremely rare variations and remain unclassified. Possible intraoperative problems concerning postoperative complications are also emphasized.

“…Moreover, it has been detected intraoperatively (84%) by the injection of methyleneblue into the splenic a. [40]. 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.…”

“…In particular, although the division of an artery at its root brings about a complete en bloc lymphadenectomy of the area, radical lymphadenectomy does not always require division of the artery. The posterior gastric a. is commonly present, it is one of the trunks supplying the upper part of the posterior gastric wall, it is located in a deep abdominal site [5,29] and can be in connection with lymph nodes [40]. These nodes, according to the latest TNM edition [10], are considered as first level (N1) if located within 3 cm from the macroscopic border of the primary tumor or as second level (N2) if located beyond 3 cm.…”

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

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.
