Moreover, the risk of stroke in CAO patients with objective cerebral perfusion impairment could be as high as 30% in 3 years . Endovascular treatment of CAO has been shown feasible , and successful recanalization may improve cerebral perfusion and neuro‐cognitive function . However, CAO recanalization is still controversial and technically challenging, with potential complications of peri‐procedural stroke, intracranial hemorrhage (ICH) or subarachnoid hemorrhage (SAH), pseudo‐aneurysm formation, and carotid‐cavernous fistula (CCF) . Established symptomatic CCF, such as diplopia, ptosis and loss of visual acuity, associated with head and facial trauma or surgery usually requires endovascular therapy for treatment. However, the manifestation and management of iatrogenic CCF during CAO endovascular recanalization have not been well described in the literature. Therefore, we performed a retrospective analysis on our database regarding these important issues.MATERIALS AND METHODSPatient selectionWe conducted a retrospective analysis of consecutive de novo CAO recanalization procedures performed from October 2004 to April 2015 in National Taiwan University Hospital
