Key Points

  • The research aims to identify factors that influence cranial nerve palsy in patients with cavernous sinus dural arteriovenous fistulas.
  • Examined the association between fistula type and cranial nerve palsy onset.
  • Evaluated the impact of coil packing location on treatment outcomes.
  • Analyzed the effects of hypertension and initial symptom severity on recovery.
  • Initial cranial nerve palsy was associated with proliferative fistula type and contralateral feeders.
  • Majority of patients achieved complete resolution of cranial nerve palsy.
  • Hypertension, severe symptoms, and retreatment were linked to lower recovery rates.

Abstract

Proliferative fistula type and contralateral feeders were associated with initial CNP in CSDAVFs, while coil packing location significantly influenced posttreatment aggravation. Complete CNP resolution was achieved in most patients, though factors such as hypertension, severe initial symptoms, and retreatment negatively affected recovery. These findings highlight key clinical and angiographic variables critical for guiding treatment strategies and predicting outcomes in patients with CSDAVF.
