Aims: Visceral artery aneurysms (VAAs), although rare, represent a life-threatening disease with high mortality rates. With the more frequent use of diagnostic tests, there has been an incidental detection of these lesions which are mostly asymptomatic. It follows that surgeons are increasingly called to decide the most appropriate management of VAAs between an open surgical or endovascular approach and among the different endovascular options currently available.

Objectives: The patients suffering from chronic mesenteric ischemia are at risk of malnutrition due to the fear of food and the weight loss. However the impact of malnutrition on the morbi-mortality at the time of surgery remains little studied, just as its prevalence. The main objective of this study was to evaluate the influence of malnutrition on the survival of the patients operated for chronic mesenteric ischemia. Read More

Introduction: Fenestrated/branched endografts (FB-EVAR) are valid options to treat thoraco-abdominal aortic aneurysms (TAAA). Successful repair requires target-visceral-vessels (TVV) manipulation with possible splanchnic ischemia. Aim of the study was to evaluate the clinical impact of splanchnic ischemia occurring in FB-EVAR for TAAA. Read More

Median arcuate ligament (MAL) syndrome usually involves the celiac artery (CA) only. Far less frequently, both the CA and superior mesenteric artery (SMA) are compressed, leading to chronic mesenteric ischaemia.

Introduction: Given the few reports regarding the salvage methods for managing jejunal necrosis, finding candidates for a meta-analysis or systematic review is difficult. Thus, this study aimed to describe the interventions for jejunal necrosis and investigate important points relating to this condition.

Methods: The interventions used to treat free jejunal necrosis are external fistula formation with jejunal debridement, secondary reconstruction of the local site, and overall status improvement, and re-free jejunal transfer with removal of the necrotic jejunum. Read More

Endovascular treatment of chronic mesenteric ischemia is currently the treatment of choice, regardless of the number of involved vessels. Unlike other anatomic areas, the hyperperfusion produced by revascularization and the consecutive reperfusion syndrome is only described in cases of acute bowel ischemia, which is usually resolved with traditional surgery. We present a case of severe hyperperfusion syndrome secondary to endovascular correction with stents of a critical ischemia affecting the celiac trunk and superior mesenteric artery. Read More

Although conventional bowel preparation for colonoscopy rarely causes serious complications, such complications can be fatal and, therefore, require early recognition and prompt treatment. Herein, we report a case of non-occlusive mesenteric ischemia (NOMI) induced by polyethylene glycol with an ascorbate component (PEG + Asc) that was used as a colonic bowel preparation. An- 82-year-old woman with a medical history of hypertension, atrial fibrillation and mild chronic renal failure received a cancer screening colonoscopy. Read More

Retroperitoneal fibrosis (RPF) is a condition characterized by chronic inflammatory and fibrotic changes in the retroperitoneum that can lead to serious complications including kidney failure, mesenteric and limb ischemia, and deep venous thrombosis among others. Affected individuals may present with nonspecific symptomology that would require a high clinical index of suspicion for prompt diagnosis. We herein discuss a case of a young African-American man with recurrent deep venous thrombosis who presents with a 4-week history of constant aching pain of abdomen and back and kidney failure.

The superior mesenteric artery (SMA) provides vital blood supply to the midgut, and an acute abnormality can rapidly precipitate bowel ischemia and infarction and lead to morbidity and mortality. Vascular diseases that acutely compromise the SMA threaten its tributaries and include occlusion, dissection, aneurysm rupture, pseudoaneurysm, vasculitis, and SMA branch hemorrhage into the bowel. Emergency medicine physicians rely on the radiologist to identify SMA abnormalities, to characterize them, and to detail findings that guide the appropriate triage of these patients. Read More

Sclerosing mesenteritis is a rare non-neoplastic disorder characterized by fat necrosis, chronic inflammation, and fibrosis typically of the small bowel mesentery. Our understanding of this disorder is limited by its rarity as well as inconsistent terminology used across the literature. While prior abdominal surgery or trauma, autoimmunity, infection, ischemia, and malignancy have been suggested to be involved in the pathogenesis of the disorder, it remains poorly understood.
