In our series,
using simple coiling and multiple microcatheters technique in endovascular treatment of distal basilar artery aneurysms showed satisfactory immediate and follow-up anatomical and clinical results.
In the immediate anatomical results,
96.67% of the treated aneurysms showed complete occlusion or neck remnant.
In the longterm anatomical results,
80% showed complete occlusion or neck remnant.
No morbidity or mortality was related to the operative technique in the immediate and long term clinical results.
Our results showed that coiling is safe and effective with less morbidity and mortality rates in comparison with clipping,
a similar result was attained by Lusseveld et al.,
{7},
Sekhar et al.,
{8} and Nanda et al.,
{9}.
Our results showed that there is a significant correlation between the aneurysm neck size and the immediate anatomical results namely,
the larger the aneurysm neck size,
the more likely the neck remnant and aneurysm remnant after embolization.
In comparison with balloon remodelling technique,
our series showed satisfactory immediate and follow-up anatomical and clinical results,
this was also concluded by Chung et al.,
{10} while Pierot,
et al {11} showed same outcome in both techniques.
Evaluated against the stent-assisted technique,
our results are more satisfactory in the immediate and follow-up results and safer as multiple catheters technique doesn’t require antiplatelet drugs,
this was supported by Zhang et al.,
{12} while Ozretic et al.,
{13} and Hetts et al.,
{14} concluded that there was no difference in the rate of recurrence and retreatment between the two techniques.
Our results in contrast to flow diverters were better especially in the clinical outcome; this was proved by Toth et al.,
{15} and Rooij et al.,
{16}.
Compared to the WEB device,
our immediate anatomical and clinical results were more satisfactory,
Pierot et al. in two studies {17,18} confirmed the safety and efficacy of this technique,
however further follow up of these patients is required to confirm these results and to assess the long-term anatomical and clinical results.
3D bare platinum coils were used in coiling of all aneurysms in our series,
in comparison with the results published in the literature using bioactive coils,
we concluded that 3D bare platinum coils are not inferior to bioactive coils {19,20}.
From the current study,
we can conclude that distal basilar artery aneurysms treated with simple coiling and multiple microcatheters technique showed satisfactory immediate and follow-up anatomical and clinical results when compared with other complex techniques; balloon remodelling technique,
stent-assisted coiling,
flow diverters and WEB device in the literature.
