RESUMEN
BACKGROUND AND PURPOSE: Coronavirus disease 2019 (COVID-19) is associated with a small but clinically significant risk of stroke, the cause of which is frequently cryptogenic. In a large multinational cohort of consecutive COVID-19 patients with stroke, we evaluated clinical predictors of cryptogenic stroke, short-term functional outcomes and in-hospital mortality among patients according to stroke etiology. METHODS: We explored clinical characteristics and short-term outcomes of consecutively evaluated patients 18 years of age or older with acute ischemic stroke (AIS) and laboratory-confirmed COVID-19 from 31 hospitals in 4 countries (3/1/20-6/16/20). RESULTS: Of the 14.483 laboratory-confirmed patients with COVID-19, 156 (1.1%) were diagnosed with AIS. Sixty-one (39.4%) were female, 84 (67.2%) white, and 88 (61.5%) were between 60 and 79 years of age. The most frequently reported etiology of AIS was cryptogenic (55/129, 42.6%), which was associated with significantly higher white blood cell count, c-reactive protein, and D-dimer levels than non-cryptogenic AIS patients (p

Purpose: Intraoperative identification and excision of specific lymphadenopathies is not always easy; it is, therefore, important to have complementary techniques that help us in the identification of these structures intraoperatively. The aim of this study is to present preliminary results of the use of ROLL technique (radioguided occult lesion localisation) as a method of excisional biopsy in the head and neck territory. Material and methods: We present 10 cases of patients with difficult to localise lymphadenopathies in the head and neck territory that underwent the ROLL technique. The radiotracer was only injected in the nodes that we wanted to study; in this way, all of them were correctly identified and extracted without resecting those that had no signs of pathology avoiding removing healthy lymphatic tissue and reducing morbidity. Results: The ROLL technique is a useful technique, since in all of the patients, the previously marked adenopathy was accurately identified and excised; we reduced the intraoperative time and avoided the complications derived from more aggressive cervical exploratory surgeries.
