“…In our study, we observed that the mean VERs of the wide-and narrow-necked aneurysms were 27.5±23.1% and 29.4±26.6%, respectively, a difference that was not statistically significant (P>0.05) (Figure 4), when the wide-necked aneurysms were treated with intracranial vascular stents. Our results were consistent with those of previous studies (8,13,14,22,25), which determined that remodelling (14), intracranial vascular stenting (8,22), TriSpan neck-bridge devices (17) and threedimensional coils (25) improve both the coil packing within and the occlusion of wide-necked aneurysms. These results suggest that stent-assisted embolization increases both the density and the packing of wide-necked aneurysms, as well as the VERs of wide-necked aneurysms.…”

AIm: To analyse the relationship between the Volume Embolization Ratio (VER), aneurysmal morphological characteristics, and intracranial aneurysm embolization results. mAterIAl and methOds:Using the clinical and radiological data of 57 cerebral aneurysms treated with detachable coils, VERs were calculated. The relationship between the VER and aneurysm embolization was analysed. results:We observed that the mean VERs of the small, medium, large, and giant aneurysms were 40.8±26.5%, 18.6±16.1%, 2.3±2.1% and 0.4±0.1%, respectively and the differences were statistically significant (F=7.091, P=0.000). The mean VERs of the wide-and small-necked aneurysms were 27.5±23.1% and 29.4±26.6%, respectively. There was no significant difference between these values. The mean VERs of aneurysms causing complete occlusion, neck residual and partial embolization were 41.8±29.3%, 31.4±21.2%, 12.3±15.1%, respectively, and the differences were statistically significant (F=7.97, p=0.001). COnClusIOn:The VER is an objective index with which to evaluate aneurysm embolization and is a significant predictor of the efficacy of intracranial aneurysm embolization.

“…From then on, with improvements in microstent technology, more reports from various centers describing the experimental and clinical use of different stents for embolization assistance has reported good results in the literature. [7][8][9][10][11][12][13] Up till now, several literatures have demonstrated the technical feasibility, efficacy of treating complicated intracranial aneurysms. [14][15][16][17] The stent can provide a permanent scaffold across the aneurysm neck, which may prevent coil prolapse into the parent artery and allow for safer packing of the aneurysm with a denser coil mesh.…”

“…Finally, a stent also provides a matrix for endothelial growth. The luminal surface of the stent is covered by a layer of neointima and the segment from which the aneurysm arises is thereby remodeled 1,[17][18][19][20] . The approach to posterior circulation arteries by endovascular devices is quite direct and now there are available new, autoexpansible stents designed for intracranial use.…”

-Basilar artery (BA) dissecting aneurysms pose difficulties to treatment because both bleeding and thrombosis can happen in the same patient, clinical course is unpredictable and high morbidity is usual. We report the case of a 37-year-old woman with a BA aneurysm probably caused by arterial dissection, presenting embolic and hemorrhagic complications. The aneurysm was submitted to endovascular treatment with stenting and coil embolization. Clinical and radiological results were excellent and no complications were observed, suggesting that BA stenting and coil embolization may be a safe and effective treatment for this condition.KEY WORDS: basilar artery dissection aneurysm, endovascular treatment, stenting, coil embolization. Tratamento endovascular de aneurisma dissecante da artéria basilarRESUMO -Aneurismas associados a dissecção da artéria basilar (AB) apresentam dificuldades terapêuticas, pois sangramentos e fenômenos trombóticos podem ocorrer no mesmo paciente, seu curso clínico é imprevisível e sua morbidade, alta. Relatamos o caso de uma paciente de 37 anos com aneurisma de artéria basilar provavelmente causado por dissecção arterial, apresentando-se com complicações hemorrágicas e embólicas. O aneurisma foi submetido a tratamento endovascular com colocação de "stent" e embolização com molas. Os resultados clínico e radiológico foram excelentes e nenhuma complicação foi observada, sugerindo que o tratamento dos aneurismas de AB dissecantes com colocação de "stent" e embolização com molas possa ser seguro e eficaz. PALAVRAS-CHAVE: aneurismas associados a dissecção da artéria basilar, tratamento endovascular, embolização com molas, "stent".
