Abstract
For an effective and durable occlusion of cerebral aneurysm, the aneurysmal sac should be packed by detachable coils as densely as technically possible. Navigating microcatheters, coil framing, and packing of the sac are the major technical steps of aneurismal embolization. There are several additional techniques and devices for dealing with wide-necked aneurysms. This paper reviews and describes various techniques for safe navigation of microcatheters including tip shaping, selection of the shapes for initial coil framing, selection of coil sizes techniques for packing, and techniques of balloon- or stent-assisted coiling for embolization of wide-necked lesions.
Key Words: Aneurysm; Coil embolization; Embolization technique; Device
