Extended Use of Distal Embolic Protection Devices in Treatment of Distal Embolism During Lower Extremity Arterial Endovascular Interventions.

There is no consensus on the best treatment modality for acute distal embolization complications during endovascular interventions for peripheral arterial diseases. We report on 3 patients who underwent mechanical embolectomy using a distal embolic protection device (EPD). All patients showed angiographic evidence of distal embolism, which occurred during lower extremity limb salvage endovascular procedures.

Outcomes of Barotrauma in Critically Ill COVID-19 Patients With Severe Pneumonia.

Background: Pneumomediastinum and pneumothorax are complications which may be associated with barotrauma in mechanically ventilated patients. The current literature demonstrates unclear outcomes regarding barotrauma in critically ill patients with severe COVID-19. The purpose of this study was to examine the incidence of barotrauma in patients with severe COVID-19 pneumonia and its influence on survival.

Prediction of Heparin Induced Thrombocytopenia (HIT) Using a Combination of 4Ts Score and Screening Immune Assays.

Clinical assessment (4Ts) followed by testing for Heparin/platelet factor 4 (HPF4) antibody in intermediate and high risk patients is the standard algorithm of pretest for Heparin induced thrombocytopenia (HIT), and the diagnosis is confirmed by serotonin releasing assay (SRA) in those who have positive antibodies. We conducted a retrospective analysis in a cohort of patients treated in a community hospital who had HIT antibody test by either ELISA or a rapid Particle Immunofiltration Assay (PIFA), regardless of their 4Ts scores. Among 224 patients, 17 had HIT.
