A 74-year-old woman who was diagnosed with chronic mesenteric ischemia was under hemodialysis maintenance and had previously undergone axillobifemoral bypass surgery because of abdominal aortoiliac occlusion. Endovascular and antegrade or retrograde surgical revascularizations from the aortoiliac artery were contraindicated because of a severely calcified arteriosclerotic lesion, which included aortoiliac occlusion. During median laparotomy, revascularization consisting of bypass grafting from a previous prosthetic graft to the mesenteric arteries was performed using saphenous vein grafts. Although extra-anatomical bypass for chronic mesenteric ischemia is challenging, it provides a feasible option in cases where conventional endovascular or surgical revascularization is contraindicated., Competing Interests: Disclosure StatementAll authors have no conflict of interest., (© 2023 The Editorial Committee of Annals of Vascular Diseases.)

Only 50 cases of idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) have been reported since 1991 when it was first described. This rare etiology for chronic colonic ischemia is often debilitating to the patient's quality of life, and no effective medical treatment is available. IMHMV is frequently confused with inflammatory bowel disease because the most common presenting symptoms include abdominal pain, diarrhea, and hematochezia. Surgical resection is curative; however, the diagnosis is rarely reached preoperatively. In the present report, we have described the seventh patient with a diagnosis of IMHMV before surgery and included a literature review to help clinicians recognize this condition., (© 2022 Published by Elsevier Inc. on behalf of Society for Vascular Surgery.)

Objectives: Mesenteric vascular disease carries a high risk of mortality and morbidity; however, due to obscure clinical presentation, it can be under-recognized. Currently, epidemiology of mesenteric vascular disease remains poorly defined. The aim of this study is to analyze changes in Scottish mortality rates from mesenteric vascular disease overtime., Methods: This is a retrospective, longitudinal population-based cohort study using data extracted from death certificates and Scottish Index of Multiple Deprivation. All deaths related to a vascular disorder of the intestines recorded as an underlying cause of death between 1979 and 2014 were identified using International Classification of Disease-9 or International Classification of Disease-10 code groups. Data included demographics and location of death. The residence postcodes were used to classify socio-economic status using the Scottish Index of Multiple Deprivation., Results: From 2,142,921 deaths over 36 years, 14,530 (0.7%) were due to mesenteric vascular disease with a median (interquartile range) age of 77 and a 2:1 female to male gender ratio. The mean ± standard deviation age significantly increased from 72.6 ± 12.1 in 1979 to 76.8 ± 11.1 in 2014 ( p  < 0.001, R 2  = 0.772). Males were consistently younger than females at the time of death. The two lowest Scottish Index of Multiple Deprivation categories accounted for half of the cohort, throughout the study period ( p  = 0.068). The adjusted death rate per 100,000 population increased from 7.6 in 1979 to 12.1 in 2014., Conclusions: The reported death rates of mesenteric vascular disease in Scotland between 1979 and 2014 have nearly doubled. Mesenteric vascular disease affects twice as many women as men and is associated with social deprivation. The increased reporting of mesenteric vascular disease is likely due to increased recognition and incidence. These implications should be considered when planning healthcare provision in Scotland.

Mesenteric diseases are broadly separated into 2 groups: non-neoplastic and neoplastic. Common non-neoplastic mesenteric diseases include those involving the mesenteric vasculature and those of inflammatory processes. Mesenteric inflammatory processes can mimic a neoplastic process. Neoplastic diseases of the mesentery are rare. Generally, the morphology, behavior and diagnostic criteria for mesenteric tumors are similar to their soft tissue or organ-specific counterparts. Their recognition can be challenging because they sometimes are overlooked in differential diagnoses., Competing Interests: Disclosure None., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Endovascular approaches have replaced open surgical revascularization in most patients with mesenteric ischemia; however, flush ostial occlusions may not be amenable to traditional antegrade access. Retrograde mesenteric stenting has been previously described, but this technique requires a formal laparotomy and dissection of the proximal superior mesenteric artery. We present here a modification of this technique that requires only a "mini-laparotomy" and no open vascular repair of the superior mesenteric artery as well as a review of our initial institutional experience with this procedure. Our approach differs from previously described work by minimizing mesenteric dissection, avoiding the need for repair of an arteriotomy, and limiting the size of the laparotomy incision in this population of profoundly comorbid patients., (Copyright © 2018 Society for Vascular Surgery.

Background: Nonocclusive mesenteric ischemia (NOMI), a rare form of mesenteric perfusion, is associated with a high mortality rate, especially when the diagnosis is delayed., Objective: Optimizing the diagnostic workup and the use of modern diagnostic possibilities are needed to reduce mortality and morbidity., Recommended Approach: Recent studies recommend not yet standardized integration of computed tomography into the diagnostic workup. This paper gives an overview of the current data for the diagnosis of NOMI.

Objectives: Both open surgery (OS) and endovascular surgery (ES) have been proposed for the treatment of symptomatic chronic mesenteric ischaemia (CMI). OS was considered the gold standard but ES is increasingly proposed as the first option. The aim was to report long-term outcomes associated with OS in patients suffering CMI in the modern era in order to help in choose between the two techniques., Materials and Methods: A retrospective single centre analysis of all consecutive digestive artery revascularizations performed for CMI between January 2003 and December 2012 was carried out. Primary outcomes were 30 day mortality and morbidity, and secondary outcomes were survival, primary patency (PP), secondary patency (SP), and freedom from digestive symptoms, depending on the completeness of the revascularization performed., Results: Eighty-six revascularizations were performed. Median follow up was 6.9 years (range 0.3-20.0). The 30 day mortality and morbidity rates were respectively 3.5% and 13.9%. Ten year survival was 88% for complete revascularization (CR) and 76% for incomplete revascularization (IR) (p = .54). The PP was 84% at 10 years for CR and 87% respectively for IR (p = .51). The 10 year SP was 92% for CR and 93% for IR (p = .63). Freedom from digestive symptoms was influenced by the completeness of revascularization: 79% for CR versus 65% for IR at 10 years (p = .04)., Conclusions: OS for CMI, especially complete revascularization, provides lasting results despite high morbidity., (Copyright © 2015 European Society for Vascular Surgery.
