Figure 4: (a) Head computed tomography scan demonstrates subarachnoid hemorrhage in the sylvian and interhemispheric fissures. (b) Right internal carotid artery injection shows an aneurysm of the A1–A2 segment of the anterior cerebral artery. (c) Later, arterial phase during coiling shows contrast extravasation (arrow). (d) Oblique and (e) lateral internal carotid artery projections show temporary coiling of the internal carotid artery terminus and anterior cerebral artery take-off to create a subocclusive flow state. (f) Computed tomography scan head shows an increase in subarachnoid hemorrhage severity in addition to coiling artifact
