Isquemia arterial bilateral espontánea de extremidades inferiores por COVID-19 leve

Spontaneous bilateral lower limb arterial ischemia due to mild COVID-19

Introducción: la infección por COVID-19 ocasiona neumonía como parte del síndrome respiratorio agudo severo Coronavirus 2 (SARS-CoV-2), abarca desde la enfermedad asintomática y leve hasta una condición crítica y grave, mediada por una respuesta inmune disregulada. Presentación del caso: paciente masculino de 47 años procedente del área urbana sin antecedentes de importancia. Acudió a la sala de urgencias de un centro hospitalario refiriendo dolor en miembros inferiores de 3 días de evolución.  Manifestó que en días previos presentó sintomatología respiratoria leve.  Se tomó prueba para SARS-CoV-2 con resultado positivo. Se practicó dúplex arterial de miembros inferiores que mostró adecuado flujo sanguíneo con obstrucción completa en partes distales.  Discusión y conclusiones: se reporta el caso de un paciente con COVID-19 leve que sufrió isquemia arterial espontánea en los miembros inferiores con requerimiento de amputación. Se enfatiza en las presuntas teorías como la inmunotrombosis y la disfunción endotelial que expliquen los mecanismos causantes de esta complicación.
