Delayed care in carotid-cavernous fistula due to the Covid-19 pandemic / Atraso no atendimento de casos de fístula carótido-cavernosa devido à pandemia de Covid-19

ABSTRACT Direct carotid-cavernous fistula is a high-flow communication between the internal carotid artery and the cavernous sinus that requires early transarterial embolization for its resolution. We report a case of a patient with a direct carotid-cavernous fistula who subsequently developed a central retinal vein thrombosis due to a delay in treatment related to the health collapse experienced in the first months of the Covid-19 pandemic in Spain.

RESUMO A fístula carótido-cavernosa direta é uma comunicação de alto fluxo entre a artéria carótida interna e o seio cavernoso que requer embolização trans-arterial precoce para sua resolução. É relatado aqui o caso de um paciente com fístula carótido-cavernosa direta que posteriormente desenvolveu uma trombose da veia central da retina devido a um atraso no tratamento relacionado ao colapso de saúde experimentado nos primeiros meses da pandemia de Covid-19 na Espanha.

Púrpura de Henoch-Schönlein con compromiso ocular en un adulto: Reporte de caso y revisión de la literatura / Henoch-Schönlein purpura with ocular manifestations in adult: Case report and review of the literature

La púrpura de Henoch Schönlein es una vasculitis sistémica que afecta vasos pequeños, predominantemente en niños. Los eventos trombóticos son una rara complicación, y en la literatura solo algunos casos se han reportado. Entre éstos, un caso de oclusión de arteria central de la retina bilateral y un caso de oclusión de vena central de la retina, ambos pacientes con diagnóstico de púrpura de Henoch Schönlein, el segundo dos semanas después a iniciar hemodiálisis. Describimos el caso de un paciente adulto con diagnóstico de púrpura de Henoch Schönlein e hipertensión arterial, en insuficiencia renal crónica estadio V, en hemodiálisis hacía 20 días, quien se presentó con disminución de agudeza visual de 15 días de evolución en ojo derecho. Los hallazgos al examen ocular fueron edema del disco, edema macular, tortuosidad vascular, hemorragias en cuatro cuadrantes, se consideró una oclusión de vena central de la retina. Requirió terapia antiangiogénica y fotocoagulación laser con buena evolución.

Henoch Schönlein purpura is a systemic vasculitis that affects small vessels and mainly aff ecting children. Thrombotic events are a rare complication, and only a few cases have been reported. Among these a case of bilateral central retinal arterial occlusion in patients with Henoch Schönlein purpura, and a case of central retinal vein occlusion in a patient with Henoch Schönlein purpura over a two weeks period of hemodialysis. We describe the case of an adult patient diagnosed with Henoch Schönlein purpura and arterial hypertension, chronic renal failure in hemodialysis for 20 days; who presents with decreased visual acuity for 15 days in the right eye. The findings were disc edema, macular edema, vascular tortuosity, haemorrhages in four quadrants. Central retinal vein occlusion was considered and antiangiogenic therapy and laser photocoagulation was performed with good response.
