Visceral arteries pathologies are a broad-spectrum of conditions with an extremely low incidence, estimated at 9.2% and 6.2% per 100,000 inhabitants for chronic and acute mesenteric ischemia, respectively, and 0.01-0.2% for aneurysms. The literature regarding the topic is limited in number and fragmented, having multiple vessels involved along with rare conditions caused by different aetiologies. However, these diseases are of utmost importance considering that acute presentation is common and the treatment in urgent setting is challenging and still facing high mortality rates. There are still several grey areas regarding the treatment of these pathologies. The last decades showed an increasing utilization of an endovascular approach to treat visceral vessel diseases. On one hand, the early- and mid-term superiority of endovascular revascularization vs. open surgical repair has been demonstrated considering the reduction of morbidity and mortality, and length of stay. However, publications reporting long-term (\> five years) are still lacking. This study is a real-word, ambispective, multi-arm, multicenter study that aims to evaluate the long-term results of visceral vessel revascularization in different diseases, districts, and approaches. Patients will be divided according to the target vessel and index disease. For each subgroup, a comparison between endovascular and open repair will be performed. The primary outcome is to compare endovascular and open approach in terms of survival, further divided into overall and disease-related mortality, during long term follow-up (\> 5 years). Moreover, early and mid-term data should be considered to provide reliable results. This outcome will be stratified as well within each disease- specific arm. At the study launch, data collection of patients who have undergone visceral vessels revascularization in the previous 20 years will begin. At the same time, all new cases of visceral vessel revascularization will be proposed for enrollment and follow-up in the prospective arm. The retrospective cohort will provide informative results regarding the long-term survival of these patients. This information will be used to adjust the sample size for the prospective cohort.
