Persistence of Ventrolateral Splanchnic Longitudinal Channels

The coeliac trunk is the branch of the abdominal aorta at the level of the twelfth thoracic vertebra. Its branches namely left gastric, common hepatic and splenic arteries supply the primary organs of the supracolic abdominal compartment namely the stomach, pancreas, spleen and liver. In this article, we report case series of three cases in male cadavers aged 65yrs, 60yrs and 70yrs respectively in the Department of Anatomy, Pondicherry Institute of Medical Sciences and MVJ Medical College and Research Institute wherein we discovered that the branching pattern of the coeliac trunk varied from the usual pattern, thus the specimens were photographed to understand further. The observation of first case, common trunk from abdominal aorta showed common hepatic and superior mesenteric artery and left gastric and splenic artery aroused as another common trunk from abdominal aorta. The second case showed the superior mesenteric artery arising from coeliac trunk and the third case was observed the inferior phrenic arteries were arising from coeliac trunk. Knowledge of this variable anatomy may be useful in planning and executing surgical or radiological interventions.

Anatomical variant origin of suprarenal arteries from coeliac trunk development, and its clinical significance

Background: One of the most vascular organ in the body Adrenal gland being highly variant in vasculature and tough to approach, its knowledge needs to be updated regularly. Anatomists, Surgeons and Radiologists will be benefitted with this study and improves the quality of care provided to patients by reducing morbidity and mortality.Methods: This study was done on 48 formalin fixed cadavers (33 males, 15 females) in the department of anatomy, between 2014-2019. Coeliac trunk was skeletonized, and branches traced looking for suprarenal arterial branches.Results: Superior Suprarenal Artery originated from Inferior phrenic artery in 13(27%) cases, and these Inferior phrenic arteries were arising from the Coeliac trunk, and in one (2.03%) case Superior suprarenal artery was arising directly from Coeliac trunk and which had even replaced the Middle Suprarenal Artery. None of the Middle and Inferior Suprarenal Artery came from coeliac trunk.Conclusions: Knowledge of Superior Suprarenal Arterial variations while doing surgeries, and during radiological interventions in and around the lesser sac, and involving the Coeliac trunk helps the clinicians in reducing the morbidity and mortality.

A rare combined variation of the coeliac trunk, renal and testicular vasculature / 대한해부학회지

The authors report a rare variation of the coeliac trunk, renal and testicular vasculature in a 27-year-old male cadaver. In the present case, the coeliac trunk and superior mesenteric artery was replaced by a modified coeliacomesenteric trunk formed by hepato-gastric and superior mesenteric arteries. Here the hepato-gastric artery or trunk contributed towards the total hepatic inflow as well as a gastro-duodenal artery. A separate right gastric artery and an additional superior pancreatico-duodenal artery was also found in addition with a retro-aortic left renal vein and a bilateral double renal arterial supply. The aforementioned coeliac trunk variation, to our knowledge, has never been reported before and this variation combined with the renal vasculature requires careful surgical consideration.

Normal and variant origin and branching pattern of inferior phrenic arteries and their clinical implications: a cadaveric study.

Background: Inferior phrenic arteries, which constitute the chief arterial supply to the diaphragm, are generally the branches of abdominal aorta, however, variations in their mode of origin is not uncommon. Very less information is available regarding the functional anatomy of the inferior phrenic artery in anatomy textbooks. Methods: The present study was conducted utilizing 36 formaline-fixed cadavers between 22 years to 80 years over a period of 5 years. The frequency and anatomical pattern of the origin of the right and left inferior phrenic arteries were studied. Results: On the right side, the inferior phrenic artery arose independently from abdominal aorta in 94.4% cases and on the left side in 97.2% cases.Other sources of origin were seen in 5.55% cases. Left hepatic artery was seen as the source of origin for right inferior phrenic artery in one case while in second case left gastric artery was the source for both the right and left inferior phrenic artery. The right inferior phrenic artery is the most common source of collateral arterial supply to hepatocellular carcinoma, next to the hepatic artery. Conclusion: Knowledge of variations of inferior phrenic artery origin could be valuable during treatment of hepatic neoplasm, liver transplants, biliary tract surgery and during tanscatheter oily chemoembolisation technique.

Multiple variations in the branches of the coeliac trunk / 대한해부학회지

Here we present a unique case of variation in the branching pattern of the coeliac trunk. In the present case, the coeliac trunk was replaced by two separate arterial trunks. The first arterial trunk bifurcated into the left gastric and the left hepatic arteries. The second arterial trunk bifurcated into a splenic artery and a hepato-gastroduodenal trunk. The hepato-gastroduodenal trunk presented an unusual course and termination. The right hepatic artery arising from the hepato-gastroduodenal trunk also showed a variant course. Such rare variations are important for gastroenterological surgeons and interventional radiologists due to increase in number of transplantation surgeries and live donor liver transplantations.

A Rare Case With Multiple Variations Of Liver And Associated Arteries.

Variations of liver, its arterial supply and branching pattern of coeliac trunk are not uncommon as separate entity but this case presents several variations. During routine dissection, a multi-lobular liver, with irregular inferior margin, was observed occupying only right upper quadrant of the abdomen. An extra (accessory) lobe was hanging from its inferior surface. Common hepatic artery was giving eight branches, six on left side and two on right side. Five of the left branches were entering liver but none was passing through porta hepatis. Coeliac trunk showed tetrafurcation; the additional branch was supplying pancreas and transverse colon. Knowledge of these variations or combinations is important in open access surgeries, endoscopic surgeries and diagnostic and interventional radiology of the region.

A study of morphology of coeliac trunk in 100 cadavers.

Background: The coeliac trunk is an integral part of the circulatory system as it delivers blood from the heart to major organs within the abdominal cavity. The blood that it delivers is oxygenated and carries essential nutrients and immune system particles that can aid in life sustaining processes and can also prevent the development of diseases and complications from illnesses. Aims & Objective: (1) To study the anatomy of coeliac trunk, through its diameter, length related to their branches and distance from superior mesenteric artery. (2) To study the clinical implication of coeliac trunk in case of the variations and anomalous formation of coeliac trunk. Material and Methods: Morphology of coeliac trunk was studied in 100 formalin embalmed cadaver, aged between 50 to 80 years. Dissection method was use for this study. Results: Measurement of the length of the coeliac trunk up to the left gastric, Measurement of the length of coeliac trunk up to common hepatic and/or splenic artery, Measurement of coeliac trunk diameter, Distance between coeliac trunk and the superior mesenteric artery were taken. Conclusion: Knowledge of variations concerning the coeliac trunk is of extreme clinical importance in the areas of the laparoscopic surgery, and radiological procedures in the upper abdomen, and should be kept in mind by clinicians to avoid complications.

Coeliac Trunk Variations:Review With Proposed New Classification.

Coeliac Trunk (CT), the first ventral branch of the abdominal aorta is the major source of blood supply to the supracolic abdominal compartment. Usually, it branches into the splenic, common hepatic and left gastric arteries to supply this region. Anatomical variations of celiac trunk and its branching pattern frequently found during cadaveric dissection and diagnostic radiological imaging have been reported by numerous authors. Although the variations in coeliac trunk are usually asymptomatic, they may become important in patients undergoing diagnostic angiography for gastrointestinal bleeding or prior to an operative procedure. The knowledge of this results in more accurate treatment. In the past many years, investigators have classified the CT based on its branching pattern. However, these classifications have not been able to encompass all the types of variations that have been reported till date. Therefore, in this article we have tried to include most of the types of variations reported till date and put forward a new classification of CT that incorporates most of the variations reported so far. Besides this an attempt has been made to explain the embryological basis of these variations.

Replaced Right Hepatic Artery Associated with Uncommon Triplet Right Renal Vein: Embryological Perspective and Clinical Importance 45

Vascular variations in the abdomen are common and mostly asymptomatic. Knowledge of these variations are of tremendous clinical importance in patients undergoing invasive endovascular interventions such as liver transplantation, renal transplantation, and vascular reconstruction for congenital and acquired lesions and trans-arterial chemoembolization for the hepatic tumors. During regular dissection classes for the medical undergraduates, we encountered concurrent vascular variations in an elderly male cadaver. In the present case, we report multiple vascular anomalies involving the right hepatic artery and the right renal vein. The right hepatic artery branched off from superior mesenteric artery, and it was identified as a replaced right hepatic artery. The right kidney was drained by three renal veins, the uppermost among the three twisted around the superior branch of the right renal artery before terminating into the inferior vena cava. In addition, the left kidney was supplied by two renal arteries, and drained by a single renal vein.
