“…arterial and 10,3% venous. In a search for other studies, based on dissections and radiological investigations, about the same high level of occurrence of arterial abnormalities were found (66,[72][73][74][75][76][77][78]. On the other hand, not all the arterial variations we had defined in our study were reported by the authors of the other studies.…”

Defining minimal clearances for adequate lymphatic resection relevant to right colectomy for cancer: a post-mortem study

Right colonic lymphovascular bundles are volumes of mesenteric tissue that surround the superior mesenteric vessels anteriorly and posteriorly. Long lymphatic vessels traverse the superior mesenteric vein anteriorly/posteriorly approaching the superior mesenteric artery between arterial bundles and placing the medial clearance on the left side of the artery. These do not correlate to arterial crossing patterns. Cranial-caudal clearances determine the tissue to be removed superior/inferior to arterial origins together with long lymphatic vessels transversing independently between the lymphovascular bundles placing the weight of lymphatic resection on the mesenteric tissue and not on the level of vessel division (High tie).

“…In the recent decades, with the advent of interventional and surgical options for patients with partial hepatectomy for liver transplantation, end-stage hepatic malignancy, determining tumor respectability in patient with pancreatic and hepatobiliary malignancy, surgeons, and interventional radiologist are dependent on accurate imaging before procedures. [ 1 2 3 4 ] In variant patterns, vessels do not arise from their usual source and present as accessory or replaced vessels. Accessory vessel is a branch addition to the normal artery supply and replaced is a vessel that representing the primary blood supply to the organs.…”

Anatomical variation of celiac axis, superior mesenteric artery, and hepatic artery: Evaluation with multidetector computed tomography angiography

et al. 2016

Background:The celiac axis, superior mesenteric artery (SMA), and hepatic artery are the most important branches of abdominal aorta due to their vascularization field. The aim of our study was to evaluate the prevalence of different anatomical variation of celiac axis, SMA, hepatic artery, and its branches with multidetector computed tomography (MDCT) angiography of upper abdomen arteries.Materials and Methods:MDCT of 607 kidney donor and traumatic patients that referred to MDCT unit at Al Zahra Hospital in Isfahan from 2012 to 2015 were retrospectively evaluated. We excluded patients with history of abdominal vascular surgery and hepatic or pancreatic surgery. Computed tomography images of the patient were obtained with 64-row MDCT scanner and anatomical variations were analyzed.Results:Three hundred and eighty-eight (63.9%) of the 607 patients had classic arterial anatomy and 219 (36.1%) patients had variant types. The most common type of variation was the origin of the right hepatic artery (RHA) from SMA (9.6%), and the next common variation was the origin of the left hepatic artery (LHA) from the left gastric artery (6.9%). Variations in the origin of the common hepatic artery (CHA) were seen in 16 (2.6%) patients. Buhler arc was identified in two patients. The RHA originated from the celiac axis in 11 (1.8%) patients and from the aorta in 8 (1.3%) patients. Trifurcation of CHA into gastroduodenal artery, RHA, and LHA was detected in 11 (1.8%) patients.Conclusion:The results of the present study showed that anatomical variation occurs in a high percentage of patients. Detection of these variations can guide surgical and radiological interventional planning.

“…In the MSCT angiography study by Ognjanovic et al, the arc of Buhler was imaged in 3% of cases. [ 29 ] In Whitley et al’s meta-analysis, the presence of this arc with a pooled prevalence of 1.71%; contributes to the continuation of the vitality, especially by ensuring the continuity of liver blood supply. [ 13 ] We believe that if the presence of this arch is seen in radiological imaging methods, this should be reported in the reporting.…”

Objectives: Celiac Trunk (CT) is a vital artery and the first unmatched branch of the abdominal aorta, providing blood to upper abdominal structures, particularly the liver, stomach, and spleen. It is essential to know its anatomy in terms of pancreas, spleen, gallbladder, liver surgeries, and interventional radiological procedures such as chemoembolization. The aim of our study is to contribute to the literature with the measurements of distances between the diaphragmatic crus and vascular structures with their diameters, which have been studied insufficiently, and to detect the possible relationships between vascular variations and collateral branches. Methods: Imaging findings of 200 patients (114 males and 86 females), who underwent Multi-Section Computed Tomography examination with various indications in our center between June 2016 and July 2020, were retrospectively analyzed. The statistical relations between CT and Hepatic Artery variations, collateral formations, age, and gender were evaluated with the Spearman’s Rho Correlation Coefficient Test. Results: The distance between the crus of diaphragm and CT was 4–60 mm (mean 24.3 mm), the distance between CT and superior mesenteric artery (SMA) was 2.5–35 mm (mean 8.6 mm), CT diameter was 4.6–9.4 mm (mean 7.3 mm), and the main hepatic artery diameter was 2.4–5.8 mm (mean 4.1 mm). There was no correlation in our study between CT, Hepatic Artery variations, and their collaterals (r in range of −20,124–0.116, p>0.05). It can be said that in cases of the single accessory left hepatic artery originating from the left gastric artery, such as Michel’s Type V and Type VIII, collaterals between common hepatic artery and SMA were relatively more frequent (p=0.1). Conclusion: Our study contributed to the literature by measuring the distance between diaphragmatic crus-vascular structures, which has been little studied in the past. Frequencies of CT and Hepatic Artery variations that have been detected in our study are similar to the results of the previous studies with non-malignancy patient groups.
