Abstract/OtherAbstract:
Detection of the position of the microcatheter tip is important for safe and effective coil embolization of cerebral aneurysms, but is sometimes difficult, especially in the final stage with a high density of embolized coils. We report a new technique to deduce the position of the microcatheter tip using a novel microguidewire during coil embolization of cerebral aneurysms. The novel microguidewire (ASAHI CHIKAI 10; Asahi Intecc, Nagoya, Aichi), with a radiopaque portion of 30 mm, is advanced into the microcatheter until the distal end of the radiopaque portion reaches the coil mass edge at the neck of the aneurysm. The distance between the second marker of the microcatheter and the proximal end of the radiopaque portion of the microguidewire is checked. The position of the microcatheter tip is deduced from the distance and curve of the microguidewire. Microcatheter tips can be easily detected with this technique without complications. This technique is safe, simple, and useful for deducing the position of the microcatheter tip during coil embolization of cerebral aneurysms.
