Technical success, procedural safety, and efficacy of the Silk Vista Baby in the treatment of cerebral aneurysms over a mid-to-long-term follow-up.

Background: Long-term follow-up of cerebral aneurysms treated with the Silk Vista Baby (SVB) flow diverter is lacking. This study aimed to assess the technical success, procedural safety, and efficacy of the SVB (Balt, Montmorency, France) for the treatment of intracranial aneurysms in small cerebral vessels over a mid-to long-term follow-up. Methods: We retrospectively analyzed a prospectively maintained database of patients treated with the SVB between September 2018 and June 2021. Data regarding patient demographics, aneurysm characteristics, and technical procedures were also collected. Angiographic and clinical findings were recorded during the procedure and over a period of at least 12 months. Results: Angiographic and clinical follow-up data were available for 50 patients/50 aneurysms. The procedural complication rate was 8%. At 12 months, the final results showed a technical success rate of 100%, the re rupture rate was 0%, neuromorbidity and mortality rates of 4 and 0%, respectively, and an almost complete occlusion rate of 94%. Conclusion: Treatment of complex intracranial aneurysms with the SVB was safe and effective. Long-term results showed high rates of adequate and stable occlusions.

COVID-19 Lockdown Effects on Acute Stroke Care in Latin America.

OBJECTIVES: COVID-19 pandemic has forced important changes in health care worldwide. Stroke care networks have been affected, especially during peak periods. We assessed the impact of the pandemic and lockdowns in stroke admissions and care in Latin America. MATERIALS AND METHODS: A multinational study (7 countries, 18 centers) of patients admitted during the pandemic outbreak (March-June 2020). Comparisons were made with the same period in 2019. Numbers of cases, stroke etiology and severity, acute care and hospitalization outcomes were assessed. RESULTS: Most countries reported mild decreases in stroke admissions compared to the same period of 2019 (1187 vs. 1166, p = 0.03). Among stroke subtypes, there was a reduction in ischemic strokes (IS) admissions (78.3% vs. 73.9%, p = 0.01) compared with 2019, especially in IS with NIHSS 0-5 (50.1% vs. 44.9%, p = 0.03). A substantial increase in the proportion of stroke admissions beyond 48 h from symptoms onset was observed (13.8% vs. 20.5%, p < 0.001). Nevertheless, no differences in total reperfusion treatment rates were observed, with similar door-to-needle, door-to-CT, and door-to-groin times in both periods. Other stroke outcomes, as all-type mortality during hospitalization (4.9% vs. 9.7%, p < 0.001), length of stay (IQR 1-5 days vs. 0-9 days, p < 0.001), and likelihood to be discharged home (91.6% vs. 83.0%, p < 0.001), were compromised during COVID-19 lockdown period. CONCLUSIONS: In this Latin America survey, there was a mild decrease in admissions of IS during the COVID-19 lockdown period, with a significant delay in time to consultations and worse hospitalization outcomes.

FACTORS ASSOCIATED WITH MORTALITY IN PATIENTS HOSPITALIZED WITH COVID-19: PROSPECTIVE COHORT AT EDGARDO REBAGLIATI MARTINS NATIONAL HOSPITAL. LIMA, PERU / FACTORES ASOCIADOS A MORTALIDAD EN PACIENTES HOSPITALIZADOS CON COVID-19: COHORTE PROSPECTIVA EN EL HOSPITAL NACIONAL EDGARDO REBAGLIATI MARTINS. LIMA, PERÚ

Aim: To determine the associated factors with mortality of adult patients hospitalized with COVID-19. Methods: We conducted a prospective cohort study and included patients older than 18 years hospitalized with the diagnosis of SARS-CoV-2 infection. Those patients with a positive rapid serological test on admission, but no respiratory symptoms nor compatible images were excluded. We collected the data from clinical records. Results: A total of 813 adults were included, 544 (66.9%) with confirmed COVID-19. The mean age was 61.2 years (SD: 15.0) and 575 (70.5%) were male. The most frequent comorbidities were hypertension (34.1%) and obesity (25.9%). The most frequent symptoms on admission were dyspnea (82.2%) and cough (53.9%). A total of 114 (14.0%) patients who received mechanical ventilation, 38 (4.7%) were admitted to the Intensive Care Unit (ICU) and 377 (46.4%) died. The requirement for ventilatory support, greater lung involvement, comorbidities, and inflammatory markers were associated with mortality. It was found that for every 10 - year increase in age, the risk of dying increased by 32% (RR: 1.32 95% CI: 1.25 to 1.38). Those who required admission to the ICU and mechanical ventilation had 1.39 (95% CI: 1.13 to 1.69) and 1.97 (95% CI: 1.69 to 2.29) times the risk of dying compared to those who did not. Conclusion:  We found a high mortality rate in hospitalized patients associated with greater age, more elevated inflammatory markers, and more severe respiratory compromise.

Objetivos. Determinar los factores asociados a mortalidad de los pacientes adultos hospitalizados con COVID-19 en un hospital de referencia de la seguridad social. Materiales y métodos. Se realizó un estudio de cohorte prospectivo. Se incluyó a pacientes mayores de 18 años hospitalizados con el diagnostico de infección por SARS-CoV-2 y se excluyó a quienes ingresaron asintomáticos respiratorios, con prueba rápida serológica positiva al ingreso y sin imágenes compatibles. Los datos se recolectaron a partir de la historia clínica. Resultados. Se incluyó un total de 813 adultos, 544 (66.9%) tuvieron COVID-19 confirmado. La media de la edad fue de 61.2 años (DE: 15.0) y 575 (70.5%) fueron de sexo masculino. Las comorbilidades más frecuentes fueron hipertensión arterial (34.1%) y obesidad (25.9%). Los síntomas más frecuentes al ingreso fueron disnea (82.2%) y tos (53.9%). Un total de 114 (14.0%) pacientes recibieron ventilación mecánica, 38 (4.7%) ingresaron a UCI y 377 (46.4%) fallecieron. El requerimiento de soporte ventilatorio, el mayor compromiso pulmonar, las comorbilidades y los marcadores inflamatorios se asociaron a la mortalidad. Se halló que por cada 10 años que aumenta la edad, el riesgo de morir se incrementa en 32% (RR: 1.32 IC95%: 1.25 a 1.38). Aquellos que requirieron ingreso a UCI y ventilación mecánica tuvieron 1.39 (IC95%: 1.13 a 1.69) y 1.97 (IC95%: 1.69 a 2.29) veces el riesgo de morir, respectivamente. Conclusión. La mortalidad encontrada en nuestro estudio fue alta y estuvo asociada a la edad,  marcadores inflamatorios y compromiso respiratorio.
