Three Types of Stents Compared for Use in Endovascular Coiling of Cerebral Aneurysms

July 23, 2019—Findings from a comparative study of different types of stents used during stent-assisted coiling of cerebral aneurysms were presented at the Society of NeuroInterventional Surgery’s (SNIS) 16th annual meeting held July 22–25 in Miami Beach, Florida. The study showed that the type of stent used affects a patient’s immediate and long-term health outcomes.

According to SNIS, the multicenter analysis of radiographic and clinical outcomes in 659 patients with 670 cerebral aneurysms compared the outcomes of endovascular coiling using three types of stents—Neuroform (NEU; Stryker), Enterprise (EP; Codman Neuro, part of the DePuy Synthes Companies of Johnson & Johnson), and Low-profile Visualized Intraluminal Support (LVIS; MicroVention Terumo).

Considering factors such as patient characteristics, clinical outcomes, and complications, the investigators found a significant difference in complete occlusion among the three stents during angiographic follow-up (LVIS, 84%; NEU, 78%; EP, 67%).

Maxim Mokin, MD, the lead author of the study, commented in the SNIS announcement, “While all the stents were effective, we did find that the LVIS was associated with superior rates of angiographic occlusion in the treatment of cerebral aneurysms. This study’s findings show that randomized trials to study the outcomes of different types of stents would be a good next step to further improve clinical outcomes and safety.” Dr. Mokin is a neurointerventionist and Associate Professor in the Department of Neurosurgery and Brain Repair at the University of South Florida in Tampa, Florida.
