    A, A 74-year-old woman with an asymptomatic wide-neck left middle cerebral artery aneurysm (size: 10 × 10 × 12 mm; neck: 7 mm).

    B, Balloon-assisted coiling (arrows) with tight filling of the aneurysm and preservation of adjacent displaced M2 branches.

    C, Postembolization angiogram shows complete occlusion of the aneurysm.

    D, A 22-month follow-up angiogram shows no aneurysmal recanalization or coil compaction.

    A 62-year-old man with a ruptured wide-neck basilar tip aneurysm (size: 10 × 9 × 8 mm; neck: 6 mm).

    A and B, Frontal and lateral views, respectively.

    C and D, Control angiography after complete coiling (packing density: 34.4%).

    E (right oblique view) and F, 8-month follow-up angiography and recanalization of the posterior, right lateral aspect of the aneurysm corresponding with the maximum hydrodynamic impingement zone in the main axis of the basilar artery; a coil compaction is noted (arrows).

    G and H Control angiography after recoiling.
