In our experience, revascularization of AAMI patients as part of a multidisciplinary and multimodal management leads to encouraging results. Vascular surgeons have a central role in a dedicated intestinal stroke center.

Objective: To evaluate the clinical course of and risk factors for arterial thrombotic events in adult inpatients with coronavirus disease 2019 . Methods: All consecutive adult patients admitted for COVID-19 infection in a referral center in France and discharged from the hospital between April 1 and April 30, 2020, were included. All arterial thrombotic events that occurred through discharge were considered for analysis. Epidemiologic, demographic, clinical, laboratory, treatment, and outcome data were extracted from electronic medical records with use of a standardized data collection form. Results: Overall, 531 COVID-19þ patients were analyzed. Among them, 30 (5.6%) experienced arterial thrombotic events. Arterial thrombotic events in the setting of COVID-19 infection happened at a median of 11 (5-20) days after the first symptoms of infection; occurred in high-risk patients according to traditional cardiovascular risk factors; had an atypical pattern, such as thrombosis of the aorta, upper limb, or renal arteries or cerebral microvasculopathy in 7 (23.3%) cases; and were associated with an in-hospital mortality rate of 40%. Arterial thrombotic events increased the risk of death by 3-fold in COVID-19þ patients (hazard ratio, 2.96; 95% CI, 1.4 to 4.7; P¼.002). A subdistribution survival hazard model showed that a concentration of D-dimer above 1250 ng/mL increased the risk of arterial thrombotic events in COVID-19þ patients by more than 7 (subdistribution hazard ratio, 7.68; 95% CI, 2.9 to 20.6; P<.001). Conclusion:A dramatically high rate of in-hospital death was observed in patients who suffered arterial thrombotic events in the setting of COVID-19 infection. A D-dimer level above 1250 ng/mL at entry may identify COVID-19þ patients at risk for arterial thrombotic events.

Metabolic disorders and fluid overload are indications of continuous renal replacement therapy (CRRT) including continuous venovenous hemofiltration in patients on extracorporeal membrane oxygenation (ECMO). Direct connection of CRRT machine to the ECMO circuit provides many advantages. Nevertheless, because pressures in CRRT lines relate to ECMO blood flow, high ECMO blood flow may be associated with high pressures in CRRT lines. Thus, management of CRRT pressure lines becomes challenging. We evaluated a protocol for managing high CRRT pressures. Connections were performed according to a standardized protocol to maintain CRRT lines in the correct pressure ranges without modifying ECMO settings or inhibiting pressure alarms. To achieve this goal, the way of connecting of CRRT lines was adapted following a standardized protocol. Connection was first attempted between pump and oxygenator in the 12 patients. In five cases, high pressures in CRRT lines were successfully managed by changing the connection segment. Continuous renal replacement therapy parameters were within target levels and reduction of serum creatinine was 37%. In conclusion, management of high pressures in CRRT lines induced by ECMO could be achieved without modifying ECMO blood flow or inhibiting CRRT alarms. Iterative stops were avoided allowing efficient procedures.
