ABSTRACT
Endovascular treatment of wide-necked intracranial aneurysms remains challenging despite continuing instrumental and technical advances. A 67-year-old woman visited us for an asymptomatic unruptured aneurysm at the right distal vertebral artery and was planned to undergo endovascular coil embolization. During a second coil placement through a single microcatheter, the first coil frame was deformed and protruded into the parent artery. We decided to jack-up the protruded coil using an additional microcatheter because the tortuous vertebral artery path didn't allow a balloon or stent device to approach this aneurysm for parent artery protection. Using that microcatheter-assisted technique, the parent artery could be preserved and the aneurysm could, moreover, be excluded.
