A, Nonenhanced head CT of a female patient in her 50s showing subarachnoid hemorrhage, Hunt and Hess grade 4, and Fisher grade 4. B, Angiography reveals a blister-like aneurysm of the right supraclinoid ICA with a maximum neck diameter of 3.3 mm. C, Angiographic result immediately after deployment of FRED 4.0 × 13 mm. D, Follow-up angiography at day 17 shows a residual aneurysm filling. E and F, Follow-up angiography at 3 months demonstrates complete aneurysm obliteration. mRS score at 3 months was 1.
