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 ...

BACKGROUND: No golden diagnostic standard is available to diagnose chronic gastrointestinal ischemia (CGI). GOALS: We aimed to establish an accurate prediction model for CGI, based on clinical symptoms and radiologic evaluation of the amount of stenosis in the celiac artery (CA) and superior mesenteric artery (SMA) by means of computed tomography-angiography or magnetic resonance (MR)-angiography. STUDY: We prospectively included 436 consecutive patients with clinical suspicion of CGI in a terti...

Dedication These guidelines are dedicated to Paola De Rango, University of Perugia, Italy. She participated very actively in the process of developing these guidelines, in particular the important chapters on chronic arterial and venous mesenteric ischaemia. Six days after the second meeting of the task force she died unexpectedly, to our great despair and loss. We honour her dedication and scientific integrity by completing these guidelines. Among many other commitments she was a very productiv...

After developing a prognostic model, it is essential to evaluate the performance of the model in samples independent from those used to develop the model, which is often referred to as external validation. However, despite its importance, very little is known about the sample size requirements for conducting an external validation. Using a large real data set and resampling methods, we investigate the impact of sample size on the performance of six published prognostic models. Focussing on unbia...

Background & Aims Chronic gastrointestinal ischemia (CGI) is more common than previously thought. Visible light spectroscopy (VLS) allows for noninvasive measurements of mucosal capillary hemoglobin oxygen saturation during endoscopy. We evaluated the response of patients with occlusive CGI to treatment after evaluation by radiologic imaging of the vasculature and VLS. We also identified factors associated with response to treatment in these patients. Methods In a prospective study, we collected...

BACKGROUND: The established approach for patients suspected of chronic gastrointestinal ischemia (CGI) includes assessment of medical history, vascular imaging, such as by digital subtraction angiography, and, more recently, computed tomography angiography (CTA) or magnetic resonance angiography. Mucosal perfusion assessment techniques have recently been shown to be of additional diagnostic value, including visible light spectroscopy and gastric exercise tonometry. Gastric exercise tonometry, ho...

Abstract Objectives We determined the prevalence of classical risk factors for atherosclerosis and mortality risk in patients with CGI. Methods A case–control study was conducted. Patients referred with suspected CGI underwent a standard work-up including risk factors for atherosclerosis, radiological imaging of abdominal vessels and tonometry. Cases were patients with confirmed atherosclerotic CGI. Controls were healthy subjects previously not known with CGI. The mortality risk was calculated a...

Abstract Background The distribution of cardiovascular risk factors in patients with chronic gastrointestinal ischemia due to atherosclerosis of the splanchnic vessels (chronic splanchnic syndrome) is not well studied. The aim of this study was to determine the cardiovascular risk factor pattern in patients with chronic splanchnic syndrome. Methods From April 2003 to September 2007, atherosclerotic risk factors in consecutive patients with chronic splanchnic syndrome were compared prospectively ...

Background Splanchnic artery stenosis is common and mostly asymptomatic and may lead to gastrointestinal ischemia (chronic splanchnic syndrome, CSS). This study was designed to assess risk factors for CSS in the medical history of patients with splanchnic artery stenosis and whether these risk factors can be used to identify patients with high and low risk of CSS.

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...

Abstract Background Chronic mesenteric ischemia results from the inability to achieve adequate postprandial intestinal blood flow, usually from atherosclerotic occlusive disease at the origins of the mesenteric vessels. Patients typically present with postprandial pain, food fear and weight loss although they can present with acute mesenteric ischemia and bowel infarction. The diagnosis requires the combination of the appropriate clinical symptoms and significant mesenteric artery occlusive dise...
