OBJECTIVE: We aimed to report our experience to evaluate the outcome of patients with ruptured and unruptured PAA, when the treatment modality is decided in a multidisciplinary fashion. METHODS: In this retrospective study, we included 28 patients (8 men and 20 women) treated for a PAA in our institution between 2002 and 2012, among the 2430 patients who underwent the treatment of an intracranial aneurysm in the same period. Fifteen patients harbored a ruptured aneurysm while 13 benefited from a prophylactic treatment. The mean age at diagnosis was 52 years (range 37 to 75 SD: ± 5) in patients with ruptured aneurysm and 54.2 years (range 35 to 66 SD: ± 5) in patients with unruptured aneurysm. Endovascular treatment has been performed in 9 patients while 19 patients underwent a microsurgical treatment. Clinical outcome has been assessed using the modified Rankin scale (mRS) at 3 months. Long-term imaging follow-up included a CT angiography at 36 months for clipped aneurysms and MR angiography at 6, 18 and 36 months for coiled aneurysms. RESULTS: The median follow-up was 3.4 years (range 2.8 to 4.2). The mRS was ≤ 2 in all patients with unruptured aneurysms. In patients with ruptured aneurysm, the mRS was ≤ 2 at 3 months in 13 patients (87%). Persistent cognitive disorders were noted in 8 patients with ruptured aneurysm, 2 of them were considered as possibly related to the treatment. Aneurysm recurrence has been depicted in 4 patients (at 6 months in 3 patients and 1 year in 1 patient) requiring further treatment in all cases; all of them had an aneurysm remnant on immediate conventional angiography. No recurrence was noted in patients without remnant on immediate post-treatment angiography. CONCLUSIONS: Both endovascular and microsurgical treatment are challenged in this location. Multidisciplinary discussion is essential to optimize the management of patients with PAA.Show less >
