Systematisation of the arteries in the splenic hilus

156 abdominal preparations were explored by arteriography, corrosion and dissection. Within the meanders of the splenic artery a basic pattern can be traced. The division of the artery can easily be summarized by introducing the term of a truncus lienogastroepiploicus. The short gastric arteries are always present, and usually they are longer and more important than may appear from their name. In nearly half of the preparations (52%) an artery for the extremitas lienalis posterior is found; an artery for the extremitas lienalis anterior is very exceptional. A posterior gastric artery can be identified (36%) but it must be distinguished from several other vessels. The arteria colli pancreatis (for the neck of the pancreas) is a constant vessel that may have a superior (usually arteria lienalis) or an inferior origin (arteria mesenterica superior). It commonly supplies the transverse pancreatic artery and often the prepancreatic arcade. The arteria corporis pancreatis, too, is a constant artery. The pancreatic tail is thoroughly irrigated by usually more than one arteria caudae pancreatis. An important part of the greater curvature is not accompanied by the left gastroepiploic artery, but is supplied by the arteriae gastricae breves.

鹧鸪胃的动脉分布

为了研究鹧鸪腺胃和肌胃的动脉分布状况,本实验用血管铸型法对10只鹧鸪胃的动脉分支和分布情况进行了详细的解剖观察。结果表明,鹧鸪的腺胃由腺胃背侧动脉和腺胃腹侧动脉供应营养,肌胃由胃左动脉和胃右动脉供应,肌胃背侧动脉是胃右动脉的一末端分支,肌胃腹侧动脉由胃左动脉分出。     

The blood supply of the stomach

156 abdominal preparations were explored by arteriography, corrosion and dissection. The stomach is vascularized by four well-anastomosed main arteries: the arteria gastrica dextra and sinistra and the arteria gastroepiploica dextra and sinistra. Other important vessels include: the arteria gastroduodenalis, the arteriae gastricae breves for the upper half of the greater curvature, a posterior gastric artery (36%), an accessory left gastric artery (12%) and an arteria supraduodenalis. The main vessels give rise to some very specific collaterals, e.g. the omental arteries that may form an omental arcade (44%), supra- and infra-pyloric branches, retroduodenal branches, rami cardiaci, esophagei and tuberales and an accessory left hepatic artery. The gastroduodenal artery always arises at a fixed point.

Aberrant course of the left gastric vein in the human. Possibility of a persistent left portal vein

Two livers with an aberrant course of the left gastric vein were found in 245 Japanese cadavers. The left gastric vein collects branches from the lesser curvature of the stomach, enters the left side of the hepatogastric ligament from the cardiac region and runs towards the left side of hepatic hilus. The vein enters the liver at the left side and joins an intrahepatic branch ramified from the portal vein.     

Features of the development of the arteries of the human liver and their practical significance

By means of roentgenography and preparation methods 145 specimens of the hepatic arteries filled with roentgenopaque latex have been studied. An essential individual changeability is peculiar for the celiac trunk structure and for formation of the hepatic arteries. A "typical" structure of the celiac trunk is observed in 66%. In other cases either "noncompleteness" of the celiac trunk, or increasing number of the branches up to 4-6 are observed. As a rule, the common hepatic artery gets of the celiac trunk (93%), but sometimes it can take its origin from the aorta, the superior mesenteric artery and some other sources (7%). The hepatic artery proper only in 73% divides into the right and left branches, in other observations the latter have their independent formation. It is necessary to distinguish the independent separation of the right and left lobar hepatic arteries from some sources and presence of additional arteries. The additional arteries are the branches that are formed from any arteries when there is present the hepatic artery proper, or substituting it independent right and left branches. The additional arteries appear from the left gastric, superior mesenteric, gastro-duodenal arteries, from the aorta, the right renal artery and other sources. The peculiarities of formation of the hepatic arteries discussed can be used in clinical practice and can make the terminology more precise.     

Anatomical variations of the arterial pattern in the left hemiliver

The arterial supply to the left hemiliver was studied in 70 liver casts. The arteries were divided into 15 groups according to their origin and branching pattern. The left hemiliver was supplied by one artery in 53% of cases, by two arteries in 40% and by three arteries in 7%. The left hepatic artery, which originated from the proper hepatic artery, supplied all three left segments in 39% of specimens. The replacing left hepatic artery, which originated from the left gastric artery, supplied the whole left hemiliver in 3% of cases. The incomplete, replacing left hepatic artery supplied segments 2, 3 and a part of segment 4 in 6% of cases, and only segments 2 and 3 in 11%. There was one segmental artery for segment 2 in 86%, and two in 14%. Segment 3 was supplied by one artery in 87%, and by two in 13%. Segment 4 was supplied by one artery in 39% of cases, by two arteries in 43%, by three in 14% and by four arteries in 4%.

Chronic injury as a major factor in susceptibility to gastric cancer

The etiology of gastric cancer is still unclear. The lesser curvature of stomach is more susceptible to chronic injury due to the anatomical characteristics. Many previous studies demonstrated that the lesser curvature is the most frequent tumor site in gastric cancer. And, precancerous gastric lesions, such as atrophic and intestinal metaplasia were also typically located in the lesser curvature. The lesser curvature is the first part of the stomach to be infected with Helicobacter pylori (H. pylori) infection which was associated with precancerous gastric lesions and gastric cancer. So, chronic injury of the stomach may lead to gastric cancer have hypothesized.

Experimental use of free gastric flaps for the repair of pharyngoesophageal defects.

The repair of large pharyngoesophageal defects was accomplished experimentally in 16 dogs with revascularized free flaps from the greater curvature of the stomach. These flaps were based on the gastroepiploic vessels, and they were anastomosed to the carotid artery and external jugular vein in the neck. The procedure had a low mortality and did not lead to peptic ulceration or hyperchlorhydria in these animals.     

Anatomical variability of the left gastric artery and vein in newborn infants]

Structural variants of the left gastric artery (LGA) and left gastric vein (LGV) in newborns have been studied on 93 preparations of the stomach with ++extra-organic arteries and on 90 preparations of the stomach with ++extra-organic veins. There is certain correlation between the length of the trunk and character of branching of the LGA. A branch of the LGA, running to the posterior surface of the cardial part in the upper part of the gastric body, which is not described in the literature, has been found. Rather often in newborn children from the iliac trunk instead of the LGA, a left gastro-hepatic trunk has got off. The number of tributaries from the posterior surface of the gastric body to the LGV is found to be significantly greater than the number of tributaries from the anterior surface of the gastric body to this vein.     

Anatomical variations of the arterial pattern in the right hemiliver

The arterial supply to the right hemiliver was studied in 80 liver casts. The arteries were divided into 10 groups according to their origin and branching pattern. The right hemiliver was supplied by one artery in 96% of cases and by two arteries in 4%. When there was only one artery it originated from the proper hepatic artery in 73/77 cases and from the superior mesenteric artery in 4/77 cases. The replacing right hepatic artery which originated from the superior mesenteric vessel supplied the whole right hemiliver in 5% of cases. The incomplete replacing right hepatic artery which supplied only a part of the right hemiliver was found in 4% of cases. The anterior section (segments 5 and 8) was supplied by one artery in 61%, by two arteries in 30% and by three arteries in 9% of cases. The posterior section (segments 6 and 7) was supplied by one artery in 66%, by two arteries in 31% and by three arteries in 3% of cases. Segments 5 and 7 were predominantly supplied by one artery, whereas segments 6 and 8 by two arteries.     

树鼩(Tupaia belangeri chinensis)的脑底动脉环

用25只树鼩,从升主动脉灌注带色的橡胶乳液,在解剖显微镜下进行解剖观察,用目测微尺进行测量。大多数树鼩(22只)有完整的脑底动脉环。由左、右大脑前动脉向内侧各发一前交通动脉组成大脑前总动脉。前交通动脉口径为大脑前动脉的75～85％。后交通动脉口径与大脑后动脉相近,连于颈内动脉与大脑后动脉(基底动脉的分支)之间。测量了组成脑底动脉环有关动脉的口径。由于后交通动脉足够粗大,只有中断左、右颈总动脉和左、右椎动脉,才能造成全脑缺血。     

Anomalous course and branches of human coronary arteries

132 hearts obtained from cadavers were dissected in order to study anomalies in the course and branches of human coronary arteries. Only in 1 heart was a deviation of the circumflex branch of the left coronary artery taking a course inferior to the coronary sulcus observed. The right coronary artery travelled the entire length of the coronary sulcus on the back of the heart and gave both a posterior ventricular and a collateral branch. Circumflex branches of the right and left coronary arteries did not anastomose.     

大咯血介入治疗失败的罕见原因：腹腔动脉系统参与供血（附2例报告及文献复习）

目的：咯血的主要责任血管是支气管动脉,非支气管性体动脉参与供血是大咯血介入治疗失败的重要原因,腹腔动脉系统分支动脉参与供血更为罕见。本文通过收集相关病例,结合国内外相关研究,提高对腹腔动脉系统分支动脉为咯血责任动脉的认识,探讨其可能的病理机制、危险因素。方法：回顾分析2例腹腔动脉系统分支（胃左动脉、肝左动脉）参与大咯血供血动脉的临床及影像学资料,并报道介入栓塞治疗的效果。结果：2例患者均为支气管动脉栓塞后再发大咯血,再次血管造影显示1例肝左动脉参与供血,1例胃左动脉参与供血。栓塞上述血管后,患者止血成功。病变位于下肺、伴有胸膜增厚,提示有腹腔动脉系统分支动脉参与供血的可能。术前仔细阅读患者影像学资料,术前行主动脉分支动脉CT血管成像,可减少对责任性非支气管性体动脉的遗漏。结论：腹腔动脉系统参与供血是介入栓塞治疗后咯血复发的少见原因,了解其病理机制、危险因素,及时进行栓塞,可以降低咯血的复发率。     

Gross anatomy of the arterial supply of the stomach of the North American beaver (Castor canadensis).

The arterial pattern of the stomach of the North American beaver is studied by dissection of height specimens. The arrangement of the arteries resembles the typical mammalian pattern, although some variations are described. For example, the celiac artery gives off two large vessels, the cardiac and fundic arteries, which supply the corresponding regions of the stomach. Also, the right gastric artery originates from the gastroduodenal vessel instead of the hepatic artery.
