Multiorgan MRI findings after hospitalisation with COVID-19 in the UK (C-MORE): a prospective, multicentre, observational cohort study
Introduction:
The multiorgan impact of moderate to severe coronavirus infections in the post-acute phase is still poorly understood. We aimed to evaluate the excess burden of multiorgan abnormalities after hospitalisation with COVID-19, evaluate their determinants, and explore associations with patient-related outcome measures.
Methods:
In a prospective, UK-wide, multicentre MRI follow-up study (C-MORE), adults (aged ≥18 years) discharged from hospital following COVID-19 who were included in Tier 2 of the Post-hospitalisation COVID-19 study (PHOSP-COVID) and contemporary controls with no evidence of previous COVID-19 (SARS-CoV-2 nucleocapsid antibody negative) underwent multiorgan MRI (lungs, heart, brain, liver, and kidneys) with quantitative and qualitative assessment of images and clinical adjudication when relevant. Individuals with end-stage renal failure or contraindications to MRI were excluded. Participants also underwent detailed recording of symptoms, and physiological and biochemical tests. The primary outcome was the excess burden of multiorgan abnormalities (two or more organs) relative to controls, with further adjustments for potential confounders. The C-MORE study is ongoing and is registered with ClinicalTrials.gov, NCT04510025.
Findings:
Of 2710 participants in Tier 2 of PHOSP-COVID, 531 were recruited across 13 UK-wide C-MORE sites. After exclusions, 259 C-MORE patients (mean age 57 years [SD 12]; 158 [61%] male and 101 [39%] female) who were discharged from hospital with PCR-confirmed or clinically diagnosed COVID-19 between March 1, 2020, and Nov 1, 2021, and 52 non-COVID-19 controls from the community (mean age 49 years [SD 14]; 30 [58%] male and 22 [42%] female) were included in the analysis. Patients were assessed at a median of 5·0 months (IQR 4·2–6·3) after hospital discharge. Compared with non-COVID-19 controls, patients were older, living with more obesity, and had more comorbidities. Multiorgan abnormalities on MRI were more frequent in patients than in controls (157 [61%] of 259 vs 14 [27%] of 52; p<0·0001) and independently associated with COVID-19 status (odds ratio [OR] 2·9 [95% CI 1·5–5·8]; padjusted=0·0023) after adjusting for relevant confounders. Compared with controls, patients were more likely to have MRI evidence of lung abnormalities (p=0·0001; parenchymal abnormalities), brain abnormalities (p<0·0001; more white matter hyperintensities and regional brain volume reduction), and kidney abnormalities (p=0·014; lower medullary T1 and loss of corticomedullary differentiation), whereas cardiac and liver MRI abnormalities were similar between patients and controls. Patients with multiorgan abnormalities were older (difference in mean age 7 years [95% CI 4–10]; mean age of 59·8 years [SD 11·7] with multiorgan abnormalities vs mean age of 52·8 years [11·9] without multiorgan abnormalities; p<0·0001), more likely to have three or more comorbidities (OR 2·47 [1·32–4·82]; padjusted=0·0059), and more likely to have a more severe acute infection (acute CRP >5mg/L, OR 3·55 [1·23–11·88]; padjusted=0·025) than those without multiorgan abnormalities. Presence of lung MRI abnormalities was associated with a two-fold higher risk of chest tightness, and multiorgan MRI abnormalities were associated with severe and very severe persistent physical and mental health impairment (PHOSP-COVID symptom clusters) after hospitalisation.
Interpretation:
After hospitalisation for COVID-19, people are at risk of multiorgan abnormalities in the medium term. Our findings emphasise the need for proactive multidisciplinary care pathways, with the potential for imaging to guide surveillance frequency and therapeutic stratification

Retrograde open celiac stenting for ischemic hepatitis after pancreaticoduodenectomy
A 74-year-old man with pancreatic cancer had undergone pancreaticoduodenectomy and subsequently developed ischemic hepatitis secondary to high-grade celiac artery stenosis. Celiac antegrade stenting via brachial artery access was unsuccessful, and open antegrade bypass would have required takedown of the pancreatic and/or biliary anastomoses for adequate exposure. Retrograde open celiac stenting was, therefore, successfully performed via the gastroduodenal artery stump. His ischemic hepatitis resolved, and he was ultimately discharged with dual antiplatelet therapy. Computed tomography angiography at 6 months demonstrated a widely patent celiac stent. Retrograde open celiac stenting via the gastroduodenal artery stump is an alternative to open bypass for celiac revascularization not amenable to percutaneous antegrade stenting in patients who have undergone pancreaticoduodenectomy
Arterial Duplex Utilization Prior to First-Time Infrainguinal Peripheral Vascular Intervention Among Medicare Beneficiaries
Use of Atherectomy During Index Revascularization for Peripheral Artery Disease Among Medicare Beneficiaries
In-hospital and one-year outcomes are similar for women and men following transcarotid artery revascularization in symptomatic and asymptomatic patients
OBJECTIVE: In randomized controlled trials and retrospective series, women have higher rates of periprocedural stroke and death following carotid endarterectomy and transfemoral carotid artery stenting compared with men. We sought to compare outcomes by sex following transcarotid artery revascularization (TCAR) among patients in the Vascular Quality Initiative (VQI). METHODS: We reviewed all patients in the VQI who underwent TCAR from 2017 to 2020. We stratified the analysis by symptom status. The primary outcome was in-hospital stroke/death, and secondary outcomes were in-hospital stroke and death and 1-year stroke/death, stroke, and death. We used multivariable logistic and Cox regression models to assess the association of sex with in-hospital and 1-year outcomes after adjusting for preoperative and intraoperative characteristics. RESULTS: We identified 15,851 patients who underwent TCAR, of whom 7391 (47%) were symptomatic (2708 or 37% female) and 8460 (53%) were asymptomatic (3097 or 37% female). Women were less frequently considered anatomic high risk than men in both groups (symptomatic: 43% vs 46%; P = .004; asymptomatic: 44% vs 48%; P = .004). Among symptomatic patients, women more often had severe ≥70% stenosis (89% vs 87%; P = .02). There were no differences in in-hospital death, stroke, or stroke/death for women vs men following TCAR among symptomatic or asymptomatic patients (all P \u3e .05). After adjusting for baseline differences between groups, female sex was not associated with in-hospital stroke/death in either symptomatic (odds ratio, 1.05; 95% confidence interval, 0.72-1.56) or asymptomatic (odds ratio, 0.93; 95% confidence interval, 0.53-1.63) patients undergoing TCAR. There were also no differences in 1-year stroke, death, or stroke/death risk for women compared with men with and without symptoms on unadjusted or adjusted analyses (P \u3e .05). CONCLUSIONS: We found no sex differences in in-hospital or 1-year stroke/death following TCAR, regardless of symptom status. TCAR appears to be as safe of a surgical procedure for women as for men in patients with both symptomatic and asymptomatic carotid artery disease
