Fig 1. A 45-year-old woman presented with subarachnoid hemorrhage 6 days before this analysis.
A, Digital subtraction angiography (DSA) showed an aneurysm of anterior communicating artery ( ) with spasm of the A1 segment (arrowhead).
B, Postembolization with Guglielmi detachable coils (GDCs), the aneurysm displayed subtotal occlusion ().
C, Follow-up DSA 3 months later showed relief of the spasm of A1 segment and reopening of the embolized aneurysm ().
D, After re-embolization with GDCs, the aneurysm was totally occluded ().

Fig 2. A 49-year-old woman presented with subarachnoid hemorrhage.
A, Angiography of the left internal carotid artery (ICA) showed a large aneurysm on the C2 segment of the left ICA.
B, After Guglielmi detachable coil (GDC) embolization with stent-assisted technique, the aneurysm was nearly totally occluded.
C, Angiography of right ICA demonstrated a small aneurysm (arrow) on the right posterior communication artery.
D, The small aneurysm was totally packed with GDCs (arrow) 3 months after the large aneurysm had been embolized.
E and F, At the 6-month follow-up of the large aneurysm (E) and 3-month follow-up of the small aneurysm (F), the large one was still totally occluded, whereas the neck of the small one had reopened slightly (arrow).
G and H, At 14 months, the large aneurysm (G) remained totally occluded to the same degree; at 11 months, the neck of the small aneurysm (H) remained reopened (arrow) as in previous angiography. The small aneurysm continues to be closely monitored.
