Abstract Background Despite the enthusiasm for endovascular revascularization for chronic mesenteric ischemia (CMI), it is not clear if early benefits offset long-term patency rates. This systematic review aimed to provide an up-to-date comprehensive evidence synthesis evaluating the two approaches. Methods We searched MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus through July 15, 2016, for studies that compared the endovascular with the open surgical approach for revascularization in CMI patients. We conducted a random-effects meta-analysis to pool outcomes of interest across studies. Results We included 100 observational studies (22 comparative, 78 noncomparative; 18,726 patients; mean age, 69 years). Open surgery was associated with a statistically significant increase in the risk of in-hospital complications (relative risk [RR], 2.2; 95% confidence interval [CI], 1.8-2.6) and a nonsignificant increase in mortality at 30 days (RR, 1.57; 95% CI, 0.84-2.93). Open surgery was associated with lower risk of 3-year recurrence rates (RR, 0.47; 95% CI, 0.34-0.66) and a similar 3-year survival. Data from noncomparative studies provided similar inferences. The quality of evidence was low. Conclusions Observational evidence suggests that the endovascular approach for revascularization in patients with CMI may offer better early outcomes than open surgery, although this effect may not be durable. Long-term mortality appears to be similar.

Background It is unknown whether increased endovascular treatment of chronic mesenteric ischemia has led to decreases in open surgery, acute mesenteric ischemia, or overall mortality. The present study evaluates the trends in endovascular and open treatment over time for chronic and acute mesenteric ischemia. Methods We identified patients with chronic or acute mesenteric ischemia in the Nationwide Inpatient Sample and Center for Disease Control and Prevention database from 2000 to 2012. Trends ...

Abstract Mesenteric vascular insufficiency is a serious medical condition that may lead to bowel infarction, morbidity, and mortality that may approach 50%. Recommended therapy for acute mesenteric ischemia includes aspiration embolectomy, transcatheter thrombolysis, and angioplasty with or without stenting for the treatment of underlying arterial stenosis. Nonocclusive mesenteric ischemia may respond to transarterial infusion of vasodilators such as nitroglycerin, papaverine, glucagon, and pros...

Background Endovascular (EV) techniques are being advocated as the preferred method for mesenteric interventions because of their safety profile. However, midterm and long-term results are thought to be inferior to open interventions. We sought to compare our institutional experience with treatment of acute and chronic mesenteric ischemia (AMI and CMI, respectively) using EV and open techniques. Methods The medical records of open and EV mesenteric procedures performed at a single center were qu...

Nonrandomised studies, including case-control and cohort studies, can be challenging to implement and conduct. Assessment of the quality of such studies is essential for a proper understanding of nonrandomised studies. The Newcastle-Ottawa Scale (NOS) is an ongoing collaboration between the Universities of Newcastle, Australia and Ottawa, Canada. It was developed to assess the quality of nonrandomised studies with its design, content and ease of use directed to the task of incorporating the qual...

Chronic mesenteric ischemia (CMI) is a rare disorder that is commonly caused by progressive atherosclerotic stenosis or occlusion of one or more mesenteric arteries. Endovascular treatment for symptomatic CMI represents a viable option, especially in high-operative risk patients. We report a case of acute symptomatic CMI with chronic totally occlusion of the superior mesenteric artery (SMA) associated with significant stenosis of celiac trunk (CT) and inferior mesenteric artery (IMA) that underw...

Resumen null null La isquemia mesenterica se debe a la reduccion del flujo sanguineo a nivel intestinal. Si esta situacion se prolonga en el tiempo, es potencialmente mortal. La clinica de esta entidad es inespecifica y no suele ser visible hasta estadios avanzados de necrosis intestinal. Por tanto, recordar los factores de riesgo y mantener un indice de sospecha alto es esencial en el pronostico. Para el diagnostico seran precisas las tecnicas de imagen, como la angio-tomografia computarizada y...

BACKGROUND The mesenteric artery calcium score (MACS) identifies patients with possible chronic mesenteric ischaemia (CMI) using standard computed tomography (CT) imaging. The MACS does not necessitate a dedicated computed tomography angiography (CTA) which is required for evaluation of mesenteric artery patency. This study aimed to test the use of a symptom and MACS based score chart to facilitate the selection of patients with a low probability of CMI, in whom further diagnostic workup can be ...

A practical screening tool for chronic mesenteric ischemia (CMI) could facilitate early recognition and reduce undertreatment and diagnostic delay. This study explored the ability to discriminate CMI from non-CMI patients with a mesenteric artery calcium score (MACS). This retrospective study included CTAs of consecutive patients with suspected CMI in a tertiary referral center between April 2016 and October 2019. A custom-built software module, using the Agatston definition, was developed and u...

OBJECTIVE Significant physiologic perturbations can occur in patients with chronic mesenteric ischemia (CMI) undergoing open mesenteric bypass (OMB). These events are frequently attributed to ischemia-reperfusion(I/R) events and are directly implicated in multiple organ dysfunction (MOD). Scoring systems [MOD and Sequential Organ Failure Assessment (SOFA)] have been derived within critical care literature to provide a composite metric for these pathophysiologic changes. The purpose of this study...
