Adult intracranial pial arteriovenous fistulas: a case report and literature review

Share

  • 1

    Intracranial pial arteriovenous fistula (PAVF) is a rare cerebrovascular lesion characterized by a direct shunt between arteries and a single draining vein.

  • 2

    A 56-year-old woman presented with severe headache and was diagnosed with a right frontal intracerebral hemorrhage due to a giant venous pouch associated with PAVF.

  • 3

    The patient underwent craniotomy for hematoma evacuation and microsurgical disconnection of the PAVF, resulting in complete removal of the hematoma.

  • 4

    Postoperative imaging confirmed total obliteration of the PAVF, and the patient was discharged neurologically intact without recurrence.

  • 5

    Adult PAVF is extremely rare and poses a high risk of hemorrhage; early diagnosis and treatment lead to excellent outcomes.
