Emergency brain CT scan showed subarachnoid hemorrhage in the left Silvian scissure and in the peri-mesencephalic cistern. CT angiography exam was performed, which showed an aneurysm of 3x2 mm of the internal carotid artery at the level of the posterior communicating segment (A-B). A balloon assisted remodeling was performed (C), using a Scepter XC balloon catheter (Microvention) and a 2 x 3 mm Target 360 coil (Striker). After balloon deflation, the coil migrated distally, at the level of the superior left M2 segment (D).After several attempts, the migrated coil was successfully retrieved with a 4 mm stent-retriever (Trevo - Striker) (E-G).The aneurysm was then successfully embolized using a 2.5 x 3 mm Target 360 coil (Striker) (F).The Patient recovered completely within 6 months, without any ischemic sequelae (H). Abstract P068 Figure 1 Results In this case the use of a stent-retriever ensured the prompt and successful treatment of a seriues possible complication which may occur during balloon assisted remodeling.Disclosure of Interest no.
