“…A recent study by Ekingen et al on the specific variation of the PHA was performed on 671 MDCT angiography images [7]. The authors classified as Type 2 the RHA + LHA + GDA originated from the CHA, with absent PHA (trifurcation of CHA) morphology [7], which is similar to the findings reported here in Case #1. Ekingen et al (2020) found this Type 2 morphology in 8.94% of cases, while the normal anatomy of the PHA was encountered in just 43.52% of their cases.…”

“…From what was observed, the variant of the RHA and LHA originating directly from the CHA which is reported here (absent PHA, Case #1) was not found among that large lot of cases, although those authors got evidence to present and discuss the absent CHA variants [24].

Hexafurcated coeliac trunks, trifurcated common hepatic artery, and a new variant of the arc of Bühler

The celiac trunk (CT) is well-known as trifurcated into the left gastric (LGA), common hepatic (CHA) and splenic (SA) arteries. Scarce reports indicate that the CT could appear cvadri-, penta-, hexa-, or even heptafurcated. Reports of CTs with six branches (hexafurcated CT) are few, less than ten. The hexafurcated CT variant was documented by a retrospective study of 93 computed tomography angiograms. Two hexafurcated CTs were found. In one case an arc of Bühler was added to the inferior phrenic arteries, LGA, CHA and SA. In the second case the dorsal pancreatic artery was added to the other five branches. That arc of Bühler descended in front of the aorta to connect with the origin of the third jejunal artery. The CHA in that second case was trifurcated into the left and right hepatic arteries, and the gastroduodenal artery; the proper hepatic 2 artery was absent. Although the hexafurcated CT, as well as the trifurcated CHA, are rarely occurring and reported anatomic variants, this doesn't mean they could not be encountered during surgical or interventional procedures, which they would complicate if not recognized. Moreover, the arc of Bühler, the embryonic remnant, was not reported previously to insert into the CT as an additional branch of it.

“…Further studies of this nature could lead to better technical planning of surgical procedures and avoiding inadvertent injuries that might compromise the results of medical procedures, leading to complications. Better knowledge of anatomical variations could ultimately contribute to reducing the rates of morbidity and mortality in endovascular procedures, abdominal surgeries, and transplantations, especially those of the liver and pancreas [11,23,36].…”

Mesenteric circulation is provided by the celiac artery (CA), superior mesenteric artery (SMA), and inferior mesenteric artery (IMA). The collateral circulation between CA and SMA and between SMA and IMA plays a protective role against intestinal ischemia in case of narrowing or occlusion of the mesenteric vessels. In our study, it is aimed to determine the CA and SMA stenosis rates in patients with CA and SMA stenosis from angiography images, the occurrence of the collateral variations, and the frequency of these variations. MethodsA total of 408 nonselective or selective CA and SMA angiographic images were taken of 215 patients (130 males, 85 females) who were admitted to Akdeniz University Hospital with symptoms of chronic mesenteric ischemia (CMI) were included. Angiography images were analyzed in regards to CA and SMA stenosis rates, and the collateral variations between mesenteric vessels. ResultsStenosis of CA was observed in 14 patients whereas the stenosis of the SMA was observed in 12 patients. The most common collateral vessel in these patients was the gastroduodenal artery. Both stenoses of CA and SMA were found in 9 patients. The Rioalan arch was the most common type of collateral vessel in these patients. ConclusionIt was observed that mesenteric circulation was mainly provided by gastroduodenal in patients with isolated CA or SMA stenosis or occlusion while in patients with stenosis or occlusion of both CA and SMA, mesenteric circulation was mainly provided by the Riolan arc. A signi cant increase was observed in the prominence of collateral vessels in patients with stenosis of more than 70%.
