Effectiveness of coil embolization of cerebral aneurysms under high magnification using biplane flat panel detector

Abstract

Objective: We report the effectiveness of embolization of cerebral aneurysms under high magnification fluoroscope using the biplane flat panel detector (BFD).
Methods: Three patients with small cerebral aneurysms (2 ruptured, 1 unruptured)were shown. These patients were treated with coil embolization using BFD (AXIOM Artis dBA Twin, SIEMENS) of all aneurysms.
Results: The magnification ratio of the flat panel of 11cm in diagonal length is about four times as large as the 42 cm flat panel. The tip of the microcatheter was clearly identified with the 11cm flat panel. The high magnified flat panel plane was suitable in the microcatheter and coil manipulation, while the other low magnified flat panel plane in the different angle was suitable to see the wide operative field including both the microcatheter and the tip of the guiding catheter. The coil herniation out of the aneurysm was easily detected with biplane fluoroscope.
Conculusion: The BFD was very useful to conduct the safe and effective coiling of the cerebral aneurysms.
