TABLE 1:
Aneurysm | Operation Method | Pouch | Diameter (mm) | Aneurysm Simulateda |
---|---|---|---|---|
Arterial-stump | Division of L CCA, far proximal | CCA stump (artery) | ≤10 to 10–25 | Any sidewall or terminal-artery aneurysm |
Bifurcation | Side-to-end anastomosis CCA to ipsilateral CCA, plus aneurysmal pouch | Vein/artery | ≤10 to 10–25 | Basilar apex, MCA bifurcation, terminal ICA, other |
Side-wall | CCA plus aneurysmal pouch | Vein/artery | ≤10 to 10–25 | ICA aneurysm (eg, paraopthalmic), supraclinoid segment |
Side branch-artery | CCA, cranial thyroidal branch; junction plus aneurysm pouch | Facial vein or artery | ≤10 | SCA, AICA, PICA aneurysm, other small aneurysm |
AICA indicates anterior inferior cerebellar artery; ICA, internal carotid artery; MCA, middle cerebral artery; PICA, posterior inferior cerebellar artery; and SCA, superior cerebellar artery.
