Abstract:

BACKGROUND: With the continuous development of the imaging equipments and embolic materials, intracranial aneurysm endovascular embolization has become a treatment method.
OBJECTIVE: To investigate the relationship of the morphological features of narrow carotid artery aneurysm around the Willis ring with the embolic material selection and endovascular embolization treatment.
METHODS: Dual-source CT angiography screening examination was performed in patients undergoing Seldinger technique of cerebral angiography with digital signature algorithm, according to the different anatomical forms of aneurysm, the appropriate choice of coil was conducted for embolization.
RESULTS AND CONCLUSION: Thirty-one patients with 36 aneurysms were successfully embolized, complete thrombosis in 31, accounting for 86.11%, the majority of embolization in 5, accounting for 13.89%. After a follow-up of 6 to 12 months, all patients did not present with re-bleeding or thrombosis. Aneurysm embolization was not only related to the aneurysm shape, but also related to embolic materials. Therefore, to choose appropriate endovascular coil according to the morphological characteristics is a safe and effective method.
