The diagnosis of chronic mesenteric ischaemia is typically based on angiographic findings along with a classic symptomatology. Only a few methods are available for functional testing to establish the diagnosis, such as indirect measurement of the splanchnic blood flow and hepatic vein oxygenation. The present case is a 76-year-old woman with weight loss and intermittent abdominal pain who was clinically suspected of chronic mesenteric ischaemia based on severe stenosis of the celiac artery and superior mesenteric artery...

OBJECTIVE: The aim of this study was to propose computed tomography angiography (CTA) based anatomical segmentation of the superior mesenteric artery (SMA), in order to standardise the reporting of occlusive lesions in acute mesenteric ischaemia (AMI). METHODS: A retrospective CTA evaluation of patients with occlusive AMI admitted between 2016 and 2021. After the screening of 468 patients, 95 were included. The SMA was segmented into proximal (S1, ostium to the inferior pancreaticoduodenal artery), middle (S2, from the inferior pancreaticoduodenal to the ileocolic artery), and distal (S3, downstream the ileocolic artery) sections...

OBJECTIVE: Aortic endografting and antegrade in situ laser fenestration of visceral arteries (LFEVAR) may be considered as an alternative to open surgery for repair of emergent complex abdominal aortic aneurysms (AAA) in fragile patients. The aim of this article is to evaluate the midterm results of LFEVAR performed with polyester endografts. METHODS: From August 2015 to December 2020, all consecutive LFEVAR performed for non-deferrable treatment of complex AAA were analysed...

Postoperative arrhythmias (PAs) are common events and have been widely investigated in cardiothoracic surgery. Within visceral surgery, a recent study revealed a significant occurrence of PA in esophageal resections. In contrast, PA in lower gastrointestinal surgery is rarely investigated and has been rudimentary described in the medical literature. The present work is a retrospective cohort study of 1171 patients who underwent surgery of lower gastrointestinal tract between 2012 and 2018. All included patients were treated and monitored in the intensive care unit (ICU) or intermediate care unit (IMC) after surgery...

BACKGROUND: Acute Mesenteric Ischaemic (AMI) is a rare condition with significant morbidity and mortality. Many causes of AMI exist, which usually begin with mucosal injury. Onset is insiduous and there is frequent diagnostic delay. Current treatments can only control established injury and prevent propagation, hence new interventions are needed. The prevention and treatment of AMI by intraluminal delivery of oxygen has yet to be investigated in the clinical setting. This article aims to systemically review experimental studies investigating this novel therapy...

Inferior mesenteric vein thrombosis (IMVT) is a rare and potentially lethal complication that can progress to mesenteric ischaemia if left untreated. We report a case of a man in his 70s with a history of polycythaemia vera (PV) with a known negative Janus kinase-2 mutation ( JAK2V617 ) who was started on testosterone therapy 2 months before presenting with left lower quadrant abdominal and flank pain. Evaluation revealed thrombocytosis and IMVT on CT scan. A non-operative approach was deferred for anticoagulation therapy...

A patient with acute occlusion of the superior mesenteric vessels resulting in superior mesenteric vessel ischaemia (SMVI) who presents to the ED with abdominal pain and unremarkable abdominal examination risks delay in diagnosis and treatment with adverse outcome. A comprehensive literature search was performed, and the evidence was reviewed. To-date, there are no accurate biomarkers of SMVI and so, heightened awareness among ED staff and rapidly actioning diagnostic imaging and surgical referral will help fast-track the patient with SMVI to surgical management...

OBJECTIVE: The aim of this study was to identify risk factors for 90 day death after elective open surgical repair (OSR) of abdominal aortic aneurysms (AAAs) in women. METHODS: This was a multicentre case control study. The nationwide Dutch Surgical Aneurysm Audit registry (2013-2019) was solely used to identify women who underwent elective OSR as eligible patients. Data for this study were subsequently collected from the patients' medical files. Women with AAA were included and those who died (cases) were compared with those who survived (controls) 90 days after surgery...

OBJECTIVE: To report clinical outcomes of COVID-19 related acute aortic thrombosis (AAT). METHODS: Consecutive COVID-19 patients presenting with AAT between April 2020 and August 2021 were included retrospectively. Clinical and radiological data were prospectively collected. RESULTS: Ten patients (men, 90%; mean age, 64 ± 2 years) were included. At the time of AAT diagnosis, four patients were in intensive care unit. Median time between diagnosis of COVID-19 and AAT was 5 days [IQR 0-8...

In this state-of-the-art review, we discuss the presenting symptoms and management strategies for vascular emergencies. Although vascular emergencies are best treated at a vascular surgical centre, patients may present to any emergency department and may require both immediate management and safe transport to a vascular centre. We describe the surgical and anaesthetic considerations for management of aortic dissection, aortic rupture, carotid endarterectomy, acute limb ischaemia and mesenteric ischaemia. Important issues to consider in aortic dissection are extent of the dissection and surgical need for bypasses in addition to endovascular repair...

OBJECTIVE: To estimate the incidence of acute mesenteric ischaemia (AMI), proportions of its different forms and short-term and long-term mortality. DESIGN: Systematic review and meta-analysis. DATA SOURCES: MEDLINE (Ovid), Web of Science, Scopus and Cochrane Library were searched until 26 July 2022. ELIGIBILITY CRITERIA: Studies reporting data on the incidence and outcomes of AMI in adult populations. DATA EXTRACTION AND SYNTHESIS: Data extraction and quality assessment with modified Newcastle-Ottawa scale were performed using predeveloped standard forms...

Although inferior mesenteric artery occlusion due to acute aortic dissection sometimes occurs, it is usually not considered an important finding. Herein, we present an extremely rare case of delayed bowel ischaemia due to inferior mesenteric artery occlusion in Stanford type A acute aortic dissection that highlights the need for cardiac surgeons to be mindful of inferior mesenteric artery occlusion in patients with superior mesenteric artery dissection or vascular anomalies in the mesenteric arteries.

BACKGROUND: Bowel ischaemia significantly increases morbidity and mortality from adhesional small bowel obstruction. Current biomarkers and clinical parameters have poor predictive value for ischaemia. Our study investigated whether neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) could be used to predict bowel ischaemia in adhesional small bowel obstruction. METHODS: This single-centre retrospective study collected clinical, biochemical and radiological data from patients with adhesional small bowel obstruction between 2017 and 2020 who underwent operative management...

OBJECTIVES: Chronic Mesenteric Ischaemia (CMI) is an underdiagnosed but severe condition. Access to functional testing is often limited and the diagnosis is usually based primarily on symptoms and imaging. One of the functional tests available is measurement of the Splanchnic Blood Flow (SBF). The purpose of the present investigation was to evaluate if changes in the splanchnic perfusion after revascularisation can be detected by measuring the SBF and hepatic vein oxygenation. MATERIALS AND METHODS: The SBF was measured in ten patients before and after revascularisation of the mesenteric arteries by either percutaneous transluminal angioplasty (n=9) or open revascularisation (n=1)...

OBJECTIVES: The aim of this study was to describe the factors affecting mid- and late aortic remodelling following TEVAR with PETTICOAT technique among patients with complicated acute or subacute type B aortic dissection. METHODS: A retrospective single center study that evaluates clinical and morphological outcomes among 65 consecutive patients. The area and diameter of the true- and false-lumen, overall aortic diameter, as well as false lumen perfusion were trended...

OBJECTIVE: This study aimed to report outcomes of patients with symptomatic acute isolated mesenteric artery dissection (IMAD) treated within a French intestinal stroke centre (ISC). METHODS: All patients with symptomatic IMAD referred to the ISC from January 2016 to January 2020 were included prospectively. Patients with aortic dissection and asymptomatic IMAD were not included. The standardised medical protocol included anticoagulation and antiplatelet therapy, gastrointestinal resting, and oral antibiotics...

BACKGROUND: Early diagnosis and prompt management of acute mesenteric ischaemia (AMI) are key to survival but remain extremely difficult, due to vague and non-specific symptoms. Serum lactate (SL) is commonly presented as a useful biomarker for the diagnosis or prognosis of AMI. The aim of our study was test SL (1) as a diagnostic marker and (2) as a prognostic marker for AMI. STUDY DESIGN: This was an ancillary multicentre case-control study. Patients with AMI at intensive care unit (ICU) admission were included (AMI group) and matched to ICU patients without AMI (control group)...

Takayasu arteritis (TAK) is a rare, large-vessel vasculitis, frequently presenting at approximately 20 years of age. Patients with TAK without characteristic clinical findings are sometimes left undiagnosed and are followed by a fever of unknown origin; and, delayed diagnosis may lead to irreversible ischaemia and organ damage. Here, we report a case of an 18-year-old woman with TAK complicated by acute pericarditis at initial presentation. She was diagnosed with idiopathic acute pericarditis and treated with non-steroidal anti-inflammatory drugs (NSAIDs)...
