Aneurysm persistence after flow diversion. A 67-year-old woman who had a previously ruptured right posterior communicating artery aneurysm with evidence of recanalization on the 6-month follow-up angiogram. She was treated with flow diversion for the neck recurrence. A 6-month follow-up DSA (lateral x-ray) after flow diversion demonstrates class C OKM grade (continued filling at the neck of the aneurysm) (white arrow). At last clinical and angiographic follow-ups at 3 years, there is no evidence of aneurysm rerupture or progression of the neck remnant on MRA (white arrow).
