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

Malperfusion syndrome results from end-organ ischemia in the setting of an aortic dissection. Malperfusion syndrome can affect any vascular bed with mesenteric malperfusion (MMP) being the most challenging associated with a 3- to 4-fold increase in mortality in both acute type A and B aortic dissections. The incidence MMP is between 66 to 100% in different literature. Read More

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
