A small saccular aneurysm of the basilar trunk (4 × 3 mm) (A) in a 56-year-old woman. Both surgery and coil occlusion were not considered suitable treatment options. A 4.5 × 15 mm p64 was deployed in the basilar artery with complete coverage of the aneurysm (B). Although the procedure was well-tolerated, the patient developed a hemiparesis and dysarthria (mRS 3) 26 days later. MR imaging shows an ischemic pontine lesion (C); a Multiplate test (not shown) confirmed insufficient platelet function inhibition. Antiaggregation was switched to ticagrelor, and the patient subsequently recovered (mRS 1). Follow-up DSA after 28 days (D) and after 421 days (E) shows complete occlusion of the aneurysm.
