Five days later, the patient was transferred to our hospital where DSA was performed, exhibiting an aneurysm in the superior segment of the clinoid process of the left ICA (Figure 1A). The aneurysm was completely occluded post-treatment (Figure 1B). A DSA examination performed 6 months after the procedure showed patent ICA without stenosis and no signs of BBA recurrence (Figure 1C).
Images of the typical cases. (A) CT scan showed symmetric suprasellar cistern SAH and hemorrhage in lateral ventricles. (B) Cerebral angiograms obtained immediately pre-embolizaton. (C) PED semi-deployed coiling. (D) and (E) Post-treatment DSA. (F) DSA follow-up 6 months after treatment.

Patient 7: This patient presented with sudden onset of severe headache and vomiting (Hunt and Hess Grade 3), and a head CT scan showed SAH in suprasellar cistern and hemorrhage in lateral ventricles (Figure 2A). Digital subtraction angiography revealed a BBA (1.8 x 2.9 mm) of the supraclinoid right ICA (Figure 2B) 3 days after the occurrence of SAH. After complete embolization was achieved, the PED was fully deployed (Figure 2C). The aneurysm was completely occluded post-treatment (Figures 2D,E). Seven months follow-up DSA showed complete obliteration (Raymond Roy Scale 1) (Figure 2F).
