Unilateral Proptosis (Exophthalmos) Caused by Axillary-Subclavian Venous Thrombosis in a Patient with Upper Extremity Arteriovenous Dialysis Fistula.

Arterialization of orbital veins is most often due to dural arteriovenous malformations of the cavernous sinus area. We report an unusual case of unilateral proptosis (exophthalmos) caused by arterialized retrograde venous flow in the external jugular vein and cavernous sinus in a patient with an upper extremity hemodialysis fistula and ipsilateral acute central venous thrombosis. The patient's symptoms improved after surgical closure of the hemodialysis fistula.

Complicaciones trombóticas arteriales en pacientes COVID-19 / Arterial thrombotic complications in COVID-19 patients

Objetivos: presentar nuestra experiencia en relación a la incidencia, pronóstico y tratamiento de pacientes COVID-19 hospitalizados con trombosis arterial periférica en un hospital terciario de Madrid. Material y métodos: se diseñó un estudio observacional de cohorte de pacientes COVID-19 confirmados (PCR-positiva) en el Hospital Universitario 12 de Octubre. Analizamos todas las trombosis arteriales periféricas sintomáticas diagnosticadas y tratadas durante los meses de marzo y abril de 2020, correspondientes a la primera ola de la pandemia. Debido a la ausencia de camas en la unidad de cuidados intensivos (UCI) y reanimación posoperatoria, toda la cirugía electiva programada fue cancelada durante este periodo y solo se realizaron cirugías urgentes. Resultados: desde el 1 de marzo al 30 de abril ingresaron en nuestro hospital 2943 pacientes con COVID-19 y de estos 261 en la UCI. Durante este periodo se realizaron 154 operaciones urgentes a pacientes COVID-19 en nuestro hospital. Catorce pacientes COVID-19 fueron diagnosticados con trombosis arterial periférica sintomática. La edad promedio fue de 74 años (rango, 50-92) y estos eventos fueron más comunes en hombres que en mujeres (12:2). De estos 14 pacientes, solo siete fueron sometidos a cirugía vascular por isquemia aguda en las extremidades. Esto representó el 4,5 % de todas las operaciones urgentes realizadas en nuestro hospital. La mortalidad posoperatoria fue 4 de 7 pacientes por retrombosis a pesar de la anticoagulación. Entre los pacientes no operados, 2 presentaban trombo aórtico flotante y evolucionaron satisfactoriamente con anticoagulación, mientras que los otros 5 pacientes debido a las malas condiciones clínicas fueron manejados con medidas paliativas hasta su fallecimiento. Ningún parámetro analítico fue predictivo de trombosis arterial. No se registraron hemorragias en esta serie...(AU)

Objectives: to describe our experience of incidence, prognosis and management of hospitalized COVID-19 patients with peripheral arterial thrombosis in a major teaching hospital in Madrid (Spain). Material and methods: we designed an observational cohort study of confirmed (PCR-test) COVID-19 patients at the Hospital Universitario 12 de Octubre. We analyzed all symptomatic peripheral arterial thrombosis diagnosed and treated during March and April 2020, which corresponds to the first wave of the pandemic. All elective scheduled surgery was canceled during this period due to absence of postoperative intensive care unit (ICU) or resuscitation beds and only urgent surgeries were performed. Results: from March 1 to April 30, 2,943 COVID-19 patients were admitted in our hospital and 261 patients in the intensive care unit (ICU). During this period, 154 urgent operations were performed on COVID-19 patients in our hospital. Fourteen COVID-19 patients were diagnosed with symptomatic peripheral arterial thrombosis. The average age was 74 (range, 50-92) and these events were more common in men than in women (12:2). Out of these 14 patients, only 7 underwent vascular surgery by acute limb ischemia. This represented 4.5 % of all urgent operations performed in our hospital. Postoperative mortality was 4 of 7 patients due to re-thrombosis despite anticoagulation. Among the non-operated patients, 2 had floating aortic thrombus and evolved satisfactorily with anticoagulation, while the other 5 patients were managed by palliatives measures due to the poor clinical conditions until they died. No analytical parameter was predictive of arterial thrombosis. No bleedings were recorded in this series...(AU)

Mortality of COVID-19 patients with vascular thrombotic complications.

PURPOSE: To analyze the survival of patients hospitalized with COVID-19 and who presented some vascular thrombotic complication. MATERIAL AND METHODS: All consecutive patients with COVID-19 who were treated during the months of March and April 2020 at our institution were included. All patients were symptomatic and the thrombotic event objectively confirmed. Patients with deep vein thrombosis (DVT), pulmonary embolism (PE), ischemic stroke, and peripheral arterial thrombosis (PAT) were included. Survival curves for all groups were analyzed using Kaplan-Meier with Log Rank test, and Cox regression. RESULTS: During the pandemic period from March-1 to April-30, 2943 patients were treated with confirmed COVID-19 in our center. 106 patients showed some symptomatic vascular thrombosis: 13 patients had PAT, 15 ischemic stroke, 20 DVT and 58 PE. 11 patients presented multiple vascular thrombosis. Although the mean age was 65 years, there were differences between groups being older those patients with arterial thrombosis. A 67.92% were men. In total, 25 patients died during their hospital admission (23.58%), with differences between groups, being more common in patients with PAT (9 patients out of 13) and ischemic stroke (8 patients out of 15), than in those with DVT (1 patient out of 20) or PE (7 patients out of 58). CONCLUSIONS: The venous thromboembolic risk in these patients is greater than the arterial, but arterial thrombosis when it occurs was associated with high mortality rates. Survival was better in patients with DVT and PE than in patients with ischemic stroke or PAT.

OBJETIVO: Presentar nuestra experiencia y analizar la supervivencia de los pacientes hospitalizados con COVID-19 y que presentaron algún proceso trombótico vascular. MATERIAL Y MÉTODOS: Se incluyeron todos los pacientes consecutivos COVID-19 que fueron atendidos durante los meses de marzo-abril 2020 en nuestra institución. Se incluyeron pacientes sintomáticos con trombosis venosa profunda (TVP), tromboembolia pulmonar (TEP), ictus isquémico y trombosis arterial periférica (TAP) confirmados objetivamente. Se analizaron las curvas de supervivencia de todos los grupos mediante Kaplan-Meier, test de Log Rank, y regresión de Cox. RESULTADOS: Durante el periodo pandémico del 1-marzo al 30-abril, se atendieron 2943 pacientes COVID-19 en nuestro centro. 106 pacientes presentaron algún proceso trombótico vascular sintomático: 13 pacientes tuvieron TAP, 15 ictus, 20 TVP y 58 TEP. 11 pacientes mostraron trombosis vasculares múltiples. Aunque la edad media fue de 65 años, fueron de edad más avanzada los que mostraron trombosis arteriales que procesos tromboembólicos venosos. El 67.92% fueron hombres. En total, 25 pacientes murieron durante su ingreso hospitalario (23.58%), existiendo diferencias entre grupos siendo más común en pacientes con TAP (9 pacientes de 13), e ictus isquémico (8 pacientes de 15), que en los de TVP (1 paciente de 20) o TEP (7 pacientes de 58). CONCLUSIONES: El riesgo tromboembólico venoso en estos pacientes es mayor que el arterial, pero la trombosis arterial cuando acontece estuvo asociada a altas tasas de mortalidad. La supervivencia fue mejor en los pacientes con TVP y TEP que en los pacientes con ictus isquémico o trombosis arterial periférica.

COVID-19-Related Aortic Thrombosis: A Report of Four Cases.

COVID-19 may predispose patients to an increased risk of thrombotic complications through various pathophysiological mechanisms. Most of the reports on a high incidence of thrombotic complications are in relation to deep vein thrombosis and pulmonary embolism, while the evidence about arterial thrombosis in patients with COVID-19 is limited. We describe 4 cases of aortic thrombosis and associated ischemic complications in patients with severe SARS-CoV-2 infection.
