[Carotid-cavernous fistula with spontaneous remission]

Area of Science:

• Neurology
• Vascular Surgery
• Radiology

Background:

• Carotid-cavernous fistulas (CCF) are abnormal connections between the carotid artery and the cavernous sinus, often resulting from head trauma.
• These fistulas can lead to serious complications like increased intracranial pressure due to rapid shunt development and hemodynamic compromise.

Observation:

• This report details a rare case of a spontaneous CCF.
• The patient presented with symptoms related to the fistula, necessitating close monitoring.

Findings:

• The carotid-cavernous fistula (CCF) demonstrated spontaneous closure.
• Follow-up angiographies confirmed complete healing of the fistula.
• The patient experienced a complete resolution of neurological deficits.

Implications:

• Spontaneous resolution is a possible outcome for some carotid-cavernous fistulas, challenging the necessity of immediate intervention in all cases.
• This finding may influence future treatment strategies for CCF, emphasizing observation in select spontaneous cases.
• Complete neurological recovery is achievable with spontaneous fistula healing.
