Five-year results of randomized bioactive versus bare metal coils in the treatment of intracranial aneurysms: the Matrix and Platinum Science (MAPS) Trial.

Background: No randomized trial of intracranial aneurysm coiling has compared long-term efficacy of polymer-modified coils to bare metal coils (BMCs). We report 5-year results comparing Matrix coils to BMCs. The primary objective was to compare the rates of target aneurysm recurrence (TAR) at 12 months.

Evaluation of clinical and anatomical outcome of staged stenting after acute coiling of ruptured intracranial aneurysms.

Introduction: Stent-assisted coiling has widened indications and improved stability of endovascular treatment of intracranial aneurysms. However, stent-assisted coiling is usually not used to treat acutely ruptured intracranial aneurysms to avoid antiplatelet therapy. The objective of this study is to evaluate a strategy of staged endovascular treatment of ruptured intracranial aneurysms including coiling at the acute phase with complementary stenting with or without coiling at the subacute phase.

Comparison of stents used for endovascular treatment of intracranial aneurysms.

Introduction: Stent-assisted coiling (SAC) has widened indications of endovascular treatment of intracranial aneurysms (wide-neck, fusiform aneurysms); moreover, it is associated with more stable anatomical results. Besides the development of other techniques such as flow diverter stents, bifurcation stents, or intrasaccular flow disruptors, SAC remains one of the most used endovascular techniques because it provides good clinical and anatomical results for most aneurysms. Several devices based on the same principle are available and have undergone many adaptations and developments over 20 years of intracranial stenting.
