Insights

Direct carotid-cavernous fistula requires prompt embolization. A delay in treatment, exacerbated by the COVID-19 pandemic in Spain, led to central retinal vein thrombosis in one patient.

Area of Science:

  • Vascular Surgery
  • Ophthalmology
  • Interventional Radiology

Background:

  • Direct carotid-cavernous fistula (CCF) is an abnormal, high-flow connection between the internal carotid artery and the cavernous sinus.
  • Early transarterial embolization is the standard treatment for direct CCF to prevent complications.

Observation:

  • A patient with direct CCF experienced treatment delays due to the healthcare system collapse during the early COVID-19 pandemic in Spain.
  • This delay in intervention was linked to the subsequent development of central retinal vein thrombosis.

Findings:

  • Delayed treatment of direct carotid-cavernous fistula can lead to severe secondary complications.
  • Central retinal vein thrombosis is a potential, serious sequela of untreated or delayed-treated direct CCF.

Implications:

  • Highlights the critical importance of timely intervention for direct CCF, even amidst public health crises.
  • Underscores the potential impact of healthcare system disruptions on managing vascular emergencies.
  • Suggests the need for robust protocols to ensure continuity of care for critical conditions during pandemics.
