“…Our type I CMT corresponds to the description of Higashi’ type I and Maldjian’ type A. Similar to our results, both Higashi et al[20] and Maldjian et al[6] reported that type I and type A were the most common type in their studies.…”

“…To the best of our knowledge, our population is the largest series of CMT cases analyzed in the literature. Except for our previous study[1], other previous studies on CMT were a series of 30 cases from cadaver dissections reported by Higashi et al[20] and a series of 36 cases from MDCT imaging reported by Maldjian et al[6]. Higashi et al[20] classified CMT into four types based on the configuration of the arteries.…”

“…Higashi et al[20] classified CMT into four types based on the configuration of the arteries. Maldjian et al[6] classified CMT into two types: Type A, corresponding to Higashi’ type I, and type B, corresponding to Higashi’ type III. Type A tended to be shorter single common trunk than type B.…”

BACKGROUNDIn previous studies, celiomesenteric trunk (CMT) was narrowly defined as a hepato-gastro-spleno-mesenteric (HGSM) trunk, but other possible types were ignored. With the widespread use of multidetector computed tomography (MDCT) angiography, it is easy to collect a large sampling of data on arterial anatomy of the abdomen in daily radiological practice. A new classification system for CMT may be created based on its MDCT angiographic findings and variation patterns.AIMTo identify the spectrum and prevalence of CMT according to a new classification based on MDCT angiographic findings, and discuss the probable embryological mechanisms to explain the CMT variants.METHODSA retrospective study was carried out on 5580 abdominal MDCT angiography images. CMT was defined as a single common trunk arising from the aorta and its branches including the superior mesenteric artery and at least two major branches of the celiac trunk. Various types of CMT were investigated.RESULTSOf the 5580 patients, 171 (3.06%) were identified as having CMT. According to the new definitions and classification, the CMT variants included five types: I, II, III, IV and V, which were found in 96 (56.14%), 57 (33.33%), 4 (2.34%), 3 (1.75%) and 8 (4.68%) patients, respectively. The CMT variants also were classified as long type (106 patients, 61.99%) and short type (65 patients, 38.01%) based on the length of single common trunk. Further CMT classification was based on the origin of the left gastric artery: Type a (92 patients, 53.80%), type b (57 patients, 33.33%), type c (11 patients, 6.43%) and type d (8 patients, 4.68%).CONCLUSIONWe systematically classified CMT variants according to our new classification system based on MDCT angiographic findings. Dislocation interruption, incomplete interruption and persistence of the longitudinal anastomosis could all be embryological mechanisms of various types of CMT variants.

“…Little is known about individual variation of the anatomy of the major abdominal vessels in small animals with rare single case reports of CMT . In a retrospective study of CMT and abnormal CA branching in people, 36 cases of abnormal CA branching were described although 88% of the radiology reports from those cases did not mention the anomaly . In this study, only 2 of 32 identified abnormalities (6.3%) had been recorded in the radiology report, suggesting that these anomalies have been under diagnosed and might explain why they are rarely reported in the veterinary literature.…”

“…Since the review of the literature by Chen et al [2] hepatosplenomesenteric trunks were reported in a patient undergoing surgery to repair a splenic artery aneurysm [7] and in a patient using computerized tomography.

An understanding of the variations in the blood supply of the foregut and midgut are of critical importance to surgeons performing transplants, liver and biliary surgery, resection of tumors and various gastrointestinal procedures, as well as to interventional radiologists engaged in vessel embolization. During the dissection of a 95-year-old female cadaver as part of a course in medical gross anatomy at the University of California at Davis a rare series of vascular variations were observed. The left gastric artery arose independently from the abdominal aorta at the location of a typical celiac trunk. The common hepatic artery and splenic artery branched from a common vessel originating from a hepatosplenomesenteric trunk. Just inferior to the hepatosplenic trunk a hepatocolic trunk, which gave rise to an accessory right hepatic artery, dorsal pancreatic artery and a wandering mesenteric artery, branched from the superior mesenteric artery. This rare combination of clinically relevant variations was likely due to the abnormal partitioning and regression of the primitive splanchnic arteries during embryonic development.

Celiomesenteric and hepatosplenomesenteric trunks: characterization of two rare vascular anomalies with CT

Abstract: The location of the LGA origin distinguishes the two variants of CMT and differentiates CMT from HSMT. These anomalies are easily overlooked during evaluation of routine clinical cases.
