Fístula orbitaria supratroclear secundaria a la realización de un bloqueo para anestesia en una cirugía de catarata / Orbital supratrochlear fistula secondary to anaesthetic block in cataract surgery

Presentamos un caso de una mujer con antecedente de bloqueo peribulbar derecho previo a cirugía de cataratas que a los pocos días presenta una fístula arteriovenosa intraorbitaria supratroclear derecha. Se resuelve sin secuelas a los 3 meses mediante la realización de masajes carotídeos homolaterales intermitentes. Es la primera vez que se describe una fístula arteriovenosa intraorbitaria de localización supratroclear. Solo se han descrito 8 casos de fístula arteriovenosa intraorbitaria postraumáticas y solo uno fue después de anestesia peribulbar

A case is described of a woman with history of right peribulbar nerve block prior to cataract surgery that, within a few days, presented with a trochlear intraorbital arteriovenous fistula. This was resolved without sequelae after three months by performing intermittent homolateral carotid massages. This is the first case of supratrochlear intraorbital arteriovenous fistula. There are only 8 cases reported of traumatic intraorbital arteriovenous fistula, and only one was with post-peribulbar anaesthesia
