Aneurysm 1. Complete glue embolization of aneurysm without a coil framework.
A, After obtaining this preembolization angiogram, 50% glue was injected for 2 minutes and 28 seconds under subtracted, real-time road-map fluoroscopy.
B and C, Frozen images of early (B) and late (C) phases show slow enlargement of the cast without fragmentation.
D and E, Angiograms obtained immediately after embolization (D) and at 2-month follow-up (E) show no residual lumen in the aneurysm and a patent carotid artery.
- Fig 2.
Aneurysm 4. Partially embolized aneurysm without a coil framework.
A, After obtaining this preembolization angiogram, 40% glue was injected for 1 minute and 26 seconds under subtracted, real-time road-map fluoroscopy.
B–D, Frozen images of the early (B), middle (C), and late (D) phases show leakage of the cast along the wall.
E and F, Angiograms obtained immediately after embolization (E) and at 2-month follow-up (F) show persistent occlusion of the carotid artery.
- Fig 3.
Aneurysm 16. Complete embolization with a coil framework.
A and B, After obtaining the preembolization angiogram (A), an 8 x 20-cm GDC was introduced into the aneurysm to make a coil framework (B) and 28% glue was injected for 2 minutes and 3 seconds under subtracted, real-time road-map fluoroscopy.
C and D, Frozen images of the early (C) and late (D) phases.
E and F, Angiorams obtained immediately after embolization (E) and at 2-month follow-up (F) reveal persistent obliteration of the aneurysm.
- Fig 4.
Aneurysm 9. Partially embolized aneurysm after making a coil framework.
A–C, After obtaining a preembolization angiogram (A), an 8 × 20-cm GDC was introduced into the aneurysm to make a coil framework (B) and 50% glue was injected for 1 minute 35 seconds under subtracted, real-time road-map fluoroscopy (C). Glue could not be further injected probably because of the premature cast within the microcatheter.
D and E, Angiogram obtained immediately after embolization (D) shows a residual lumen within the aneurysm that appears smaller on the 2-month follow-up angiogram (E).
- Fig 5.
Aneurysm 13. Glue spillage during injection after making a coil framework.
A–C, After obtaining a preembolization angiogram (A), a 5 × 15-cm GDC was introduced into the aneurysm to make a coil framework (B), and 33% glue was injected for 33 seconds under subtracted, real-time road-map fluoroscopy (C). Note the acute angle of the aneurysmal neck to the parent carotid artery.
D and E, Angiogram obtained immediately after embolization (D) shows a filling defect caused by spilled glue, which has been absorbed on the 2-month follow-up angiogram (E).
