BACKGROUND/AIMS Anatomical variation of the abdominal arteries is important. Historic and modern anatomists, radiologists, as well as surgeons have reported and accumulated anatomical variations with a morphological and clinical interest. During graft procurement and reconstruction, accidental injury of the hepatic artery is more likely in the presence of hepatic arterial variation, which can b...

Chronic mesenterial ischemia (CMI) is an uncommon cause of abdominal afflictions. The spectrum of therapeutic options ranges from mesenteric artery angioplasty and stenting to surgical revascularization. We used orthogonal polarization spectral (OPS) imaging to assess microcirculation after revascularization of the celiac artery and the superior mesenteric artery. Furthermore, we applicated a p...

Patients with compression of the celiac axis by the median arcuate ligament may develop aneurysms in the pancreaticoduodenal arcades. We experienced two cases of ruptured pancreaticoduodenal artery aneurysm associated with this condition. Both patients presented with abdominal pain and shock, and abdominal contrast-enhanced computed tomography showed retroperitoneal hematoma and compression of ...

Spontaneous visceral artery dissection is an uncommon event with an unpredictable natural history with superior mesenteric artery being the most common affected artery. It is most often asymptomatic and usually diagnosed at autopsy. Pre-disposing factors are not specific but have been suggested to be pre-existing vascular disease, hypertension and pregnancy. Spontaneous resolution, definitive o...

Objective To describe the main anatomical variations of the celiac trunk and the hepatic artery at their origins. Materials and Methods This was a prospective analysis of 100 consecutive computed tomography angiography studies of the abdomen performed during a one-year period. The findings were stratified according to classification systems devised by Sureka et al. and Michels. Results The ...

Celiac artery compression syndrome (CACS) is a disease caused by celiac the median arcuate ligament (MAL), resulting in intestinal ischemic symptoms. However, clear method for invasive treatment of CACS has not yet been established because limited indications. In particular, only few reports endovascular therapy (EVT) using stents as initial are available. Here, we report case where EVT was per...
