- Fig 1.
A and B, 3D image demonstrates a left proximal A1 aneurysm. C, Microcatheter navigated from the contralateral A1 into the anterior communicating artery. D, Retrograde introduction of a microcatheter into the ipsilateral A1 via the AcomA. E, Use of a microcatheter for selective angiography, delineating the configuration of the aneurysm. F, Saccular insertion of a microcatheter. G and H, Coil embolization undertaken using a single catheter.
- Fig 2.
A, Conventional angiography shows a small proximal A1 aneurysm directed posteriorly. B, Failure of aneurysm selection through the ipsilateral ICA, despite repeat attempts using variably shaped microcatheters. C and D, Microcatheter for coil delivery navigated from the contralateral A1 to the ipsilateral A1 segment via the AcomA. E, The microcatheter is advanced into the sac after being used in selective angiography (near to the aneurysm). F, Coil insertion performed. G and H, Completion angiography confirms total occlusion of the aneurysm.
