Aims and objectives
Traditional endovascular treatment of aneurysms (coiling,
stent-assisted coiling,
balloon remodeling) has become the treatment of choice in most saccular aneurysms with results comparable to surgical clipping and a lower complication rate.
Nevertheless,
large/giant or wide-necked saccular aneurysms and fusiform aneurysms remain a challenge for the interventional neuroradiologist and endovascular technique.
In the ‘90s,
some studies [1,
2] suggested that the deployment of a stent in the parent artery,
with the aim of assisting the coiling in the aneurysm’s sac,
could determine a “diversion” of the blood flow within the parent artery by itself,
because of the modification of the regional hemodynamics,
thus promoting the thrombosis in the aneurysm.
Also,
it was observed the progressive “repavement” of the stent with endothelium,
leading to a reconstruction of the parent artery [3,
4].
Since then,
a few stents with flow diversion characteristics were developed,
with the goal of obtaining devices that could operate the exclusion of the aneurysm with or without the associated coiling of the sac.
Flow diversion is today an important tool for treatment of cerebral aneurysms,
particularly large and giant aneurysms.
The indications are still being defined and considering the patient age,
location,
size of aneurysms and clinical presentation.
The aim of this study is to review our single-centre experience with flow diverter stent,
to assess the efficacy of this endovascular technique in relieve symptomatic aneurysms.
