摘要

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.
