REVIEW
Jeroen J Kolkman, Robert H Geelkerken
Although the prevalence of mesenteric artery stenoses (MAS) is high, symptomatic chronic mesenteric ischemia (CMI) is rare. The collateral network in the mesenteric circulation, a remnant of the extensive embryonal vascular network, serves to prevent most cases of ischemia. This explains the high incidence of MAS and relative rarity of cases of CMI. The number of affected vessels is the major determinant in CMI development. Most subjects with single vessel mesenteric stenosis do not develop ischemic complaints...

We report a case of a patient with duodenal obstruction due to retroperitoneal bleeding after the rupture of a lower pancreaticoduodenal artery aneurysm. An 80-year-old female was admitted to our hospital because of nausea and vomiting. During hospitalization, she developed hemorrhagic shock. Enhanced computed tomography revealed retroperitoneal bleeding. Abdominal angiography revealed an 8-mm aneurysm of the lower pancreaticoduodenal artery, stenosis at the trunk of the celiac artery, and increased blood flow through the pancreaticoduodenal arcades from the superior mesenteric artery...

Coeliac artery stenosis due to median arcuate ligament compression or atherosclerotic disease is a frequently unrecognised challenge to recovery after pancreatoduodenectomy. The described case illustrates management with intraoperative superior mesenteric artery to hepatic artery bypass graft that led to haemorrhagic challenges postoperatively but ultimately a good recovery. Aspects of preoperative diagnosis, preoperative intervention and intraoperative management options are reviewed. Surgeons need to possess these tools to prevent complications from coeliac artery stenosis when pancreatoduodenectomy is required...

Introduction. True aneurysms of peripancreatic arterial arcades (PAAAs) are rare. Most of them coexist with celiac axis stenosis/occlusion due to median arcuate ligament (MAL) compression or atherosclerosis. The aim of this study was to evaluate the cause of celiac axis lesion and characterize the anatomy of the aneurysms. These findings may have important management implications. Material and Methods. A retrospective analysis of 15 patients with true PAAAs was performed. The diagnosis was established by contrast-enhanced CT, using a 64-MDCT scanner...

In patients undergoing pancreaticoduodenectomy (PD), unrecognized hemodynamically significant celiac axis (CA) stenosis impairs hepatic arterial flow by suppressing the collateral pathways supplying arterial flow from the superior mesenteric artery and leads to serious hepatobiliary complications due to liver and biliary ischemia, with a high rate of mortality. CA stenosis is usually due to an extrinsic compression by a previously asymptomatic median arcuate ligament (MAL). MAL is diagnosed by computerized tomography in about 10% of the candidates for PD, but only half are found to be hemodynamically significant during the gastroduodenal artery clamping test with Doppler assessment, which is mandatory before any resection...

OBJECTIVE: Spontaneous celiac artery (CA) dissection without associated aortic dissection is a rare condition. Although this condition has been diagnosed more frequently with the advent of improved diagnostic imaging modalities, its pathogenesis and treatment strategy remain to be established. The present study examined the clinical features and outcomes of conservative management of this disease. METHODS: The study included 12 patients (10 men and two women) in whom spontaneous CA dissection was diagnosed between 2007 and 2015...

In the present report, we describe a case of a patient with an asymptomatic aneurysm in the arc of Bühler (AOB), which was successfully treated by transcatheter arterial embolization. The patient presented with severe stenosis of the celiac trunk, which was suspected to be due to median arcuate ligament syndrome. Arteriography of the superior mesenteric artery indicated a rapid stream in an aneurysm in the AOB. Hence, embolization was carefully performed using detachable coils and microcoils. An arteriography performed after embolization did not show any aneurysm, and the hepatic artery and splenic artery could be detected via the pancreatic arcade, originating from the superior mesenteric artery...

This report describes perioperative hemodynamic monitoring of the common hepatic artery (CHA) during endovascular treatment of a pancreaticoduodenal arcade aneurysm, in a patient with celiac artery stenosis caused by the median arcuate ligament. Pressure monitoring was performed as a safety measure against critical complications such as liver ischemia. As the aneurysm was located in the anterior pancreaticoduodenal artery (APDA) and the posterior pancreaticoduodenal artery (PPDA) was small in caliber, the patient was considered to be at a high risk of liver ischemia...

Abdominal vascular syndromes are rare diseases. Although such syndromes vary widely in terms of symptoms and etiologies, certain imaging findings are characteristic. Depending on their etiology, they can be categorized as congenital-including blue rubber bleb nevus syndrome, Klippel-Trenaunay syndrome, and hereditary hemorrhagic telangiectasia (Rendu-Osler-Weber syndrome)-or compressive-including "nutcracker" syndrome, median arcuate ligament syndrome, Cockett syndrome (also known as May-Thurner syndrome), and superior mesenteric artery syndrome...

Median arcuate ligament syndrome (MALS) has been reported in 2-7.6 % of patients undergoing pancreaticoduodenectomy (PD). Most of the reported cases of MALS have been diagnosed perioperatively and treated radiologically or surgically before or during PD. MALS can have an acute postoperative onset after PD even if all preoperative and intraoperative evaluations are normal particularly in young patients.In this report, we present a second case of severe hepatic cytolysis secondary to MALS that developed acutely and the first patient who required acute division of the median arcuate ligament after PD...

Aneurysm in the pancreatic arcade artery is an uncommon event, and is usually associated with the condition of median arcuate ligament syndrome. The stenosis at the base of the celiac axis has been presumed to be attributable to a relative increase in flow and pressure within the pancreatic arcade, resulting in subsequent development of the aneurysm. We, herein, present a rare case with rapid development of a pancreatic arcade artery aneurysm immediately after the replacement of a thoracoabdominal aortic aneurysm...

We describe 2 cases of patients with loss of hepatic arterial flow during surgery for pancreatic head cancer due to celiac stenosis caused by median arcuate ligament compression. The first case underwent pylorus-resecting pancreatoduodenectomy for pancreatic head cancer. After resection of the gastroduodenal artery, flow in the common hepatic artery disappeared, and celiac axis stenosis was identified. Interventional stent insertion was attempted, however, it failed due to the acute angle of the celiac orifice (os)...

The median arcuate ligament syndrome is a rare disorder characterised by postprandial intestinal angina caused by compression of the coeliac artery by the median arcuate ligament. To date, the diagnosis and treatment of median arcuate ligament syndrome has remained controversial. To our knowledge, this is the first reported case of coeliac artery compression demonstrated on the four-dimensional wide-area detector CT angiogram.

The median arcuate ligament (MAL) can rarely compress both the celiac axis and superior mesenteric artery. We present a case of a 70-year male who presented with isolated episodes of upper abdominal pain and diarrhea associated with sweats and nausea. Angiography images demonstrated complete occlusion of the celiac axis and compression of the superior mesenteric artery during the expiration phases. The celiac axis was reconstituted distal to its origin by a patent Arc of Buhler. Other reported cases of multivessel MALs have produced severe symptoms in young adults requiring surgical and/or endovascular intervention...
