Semi-jailing technique.

A. A saccular aneurysm at the left middle cerebral artery (MCA) inferior division proximal portion, and a fusiform aneurysm of the inferior division just distal to the saccular aneurysm.

B. A Solitaire stent is partially deployed after partial deployment of coil loops. A short arrow indicates distal markers of the Solitaire stent and a long arrow indicates the distal tip of a Prowler plus select catheter.

C. Coiling is stably performed without catheter kickback owing to the partially deployed stent.

D. After complete coil embolization, the stent is retrieved and is removed. In this case, the stent is used for the purpose of preventing anticipated catheter kickback due to the distal flaring of the parent artery. Balloon is also anticipated to be unstable due to a distal flaring of the artery. The stent is removed after complete coiling for the further treatment of a distal fusiform aneurysm of the parent artery by using flow diverter.
