A 39-year-old man with Hunt-Hess grade 1 subarachnoid hemorrhage A 39-year-old man with Hunt-Hess grade 1 subarachnoid hemorrhage.A, Towne-view left vertebral DSA demonstrates a 16-mm basilar caput aneurysm. A 39-year-old man with Hunt-Hess grade 1 subarachnoid hemorrhage.A, Towne-view left vertebral DSA demonstrates a 16-mm basilar caput aneurysm. The aneurysm was treated with seven GDCs measuring a total length of 180 cm. Immediate post-treatment DSA demonstrated a small “dog ear” neck remnant (not shown).B, Towne-view left vertebral DSA obtained 6 weeks post treatment demonstrates slight enlargement of the “dog ear” neck remnant (arrow) at the right base of the aneurysm.C, Towne-view left vertebral DSA obtained immediately after detachment of one GDC measuring 8 cm in the dog ear neck remnant demonstrates occlusion of the neck remnant and total occlusion of the aneurysm.
