ABSTRACT:
Cerebral or intracranial aneurysm is a leading cause of subarachnoid hemorrhage. It
was initially treated with open surgical clipping but as rapid development of
technology a less invasive endovascular coiling technique of aneurysm revolutionized
the treatment. Due to tortuous anatomy of parent artery and complicated
morphology and location of aneurysm there is ongoing challenge in the complete
obliteration of aneurysms. To aid in the advances of treating aneurysm stent assisted
endovascular coiling was introduced to give more scaffold support to parent
artery and decrease events of coil protrusion from aneurysms. Many types and
generation of stents were developed. One of the most recently introduced stent
is low profile visualized intraluminal support (LVIS) stent. Due to its low profile nature it
can be used in 0.017-inch inner diameter microcatheter and reach small and
complex vessels providing high aneurysmal neck coverage which was not possible
through other traditional stent. In addition, its braided design with tantalum
strands and radiopaque markers make it more visible during stent placement and post procedure stent
evaluation. Despite of many
advantages of LVIS stent it is related to high rate of thromboembolic
complications and technical complications. Aim of this review paper was to
evaluate therapeutic safety, effectiveness and feasibility of LVIS stent in
endovascular coil embolization of intracranial aneurysms.
