Objective: Flow diverters are important tools for the treatment of intracranial aneurysms. We report a retrospective evaluation of the safety and efficacy of p64, a fully re-sheathable, detachable flow diverter, in the endovascular treatment of intracranial saccular sidewall aneurysms.
Method: Results of 180 consecutive patients with 199 aneurysms and 210 procedures (neck 3 mm, fundus 4 mm, medians), treated from 12/2011 through 09/2015, were retrospectively analyzed. 195/199 aneurysms were unruptured or beyond the acute SAH phase. Ten aneurysms were located in the posterior circulation.
Results: The average number of p64 used was 1.1 per aneurysm. The rates of permanent morbidity and mortality were 1.1% and 0.6%, respectively. Three month DSA follow-up in 183 aneurysms showed complete occlusion in 58%. Nine month DSA follow-up in 134 aneurysms showed complete occlusion in 77%. Late follow-up (>1.5 years) has been performed in 71 aneurysms, showing a complete occlusion in 80% and a neck remnant in 20%.
Conclusions: p64 offers an efficacious treatment option for intracranial sidewall aneurysms with a high aneurysm occlusion and an acceptable complication rate. The possibility to reposition or remove the device was appreciated. p64´s high density may lead to fewer devices per case and early aneurysm occlusion. Long-term follow-up data is pending.
