AI Article Synopsis
- The authors discuss two cases of patients with small, ruptured, wide-necked aneurysms in the distal vertebral artery that couldn't be treated with standard coil embolization.
- They successfully used a double-stent method, where one stent is placed within another, leading to a significant reduction in aneurysm filling right after the procedure, with total occlusion observed after a week and confirmed six months later.
- This technique offers a potential alternative for treating small, wide-necked aneurysms when conventional methods are not suitable or safe, and surgery is not an option.
Article Abstract
The authors present two cases of patients with small, acutely ruptured, wide-necked aneurysms of the distal vertebral artery that were not amenable to conventional coil embolization and were instead treated by means of a double-stent method in which one stent was placed inside another. Angiography performed immediately after the procedure revealed a significant reduction in aneurysm filling; total occlusion of the lesion was observed after 7 days and confirmed 6 months later in both aneurysms. By placing one stent inside the other, stent permeability can be reduced, which may result in significant hemodynamic changes with accelerated aneurysm thrombosis. This double-stent method may represent a therapeutic alternative, especially in cases of small, wide-necked aneurysms in which conventional endovascular techniques or stent-supported coil embolization is not considered feasible or is believed to be too dangerous, and surgical treatment is contra-indicated.

Introduction: The Flow Re-direction Endoluminal Device (FRED) is a novel flow diverter with a unique double stent design, with an inner stent composed of 48 nitinol wires, and an outer stent with 16 nitinol wires. It is designed for endovascular cerebral aneurysm treatment, although, limited data exist regarding in-stent stenosis (ISS) rates associated with FRED devices.
Methods: A registry encompassing two North American comprehensive stroke centers was the base of this study.

Background: The double-stent retriever (SR) technique has been described as an effective rescue technique when single-SR fails to induce recanalization. We aimed to assess the safety and efficacy of first-line double-SR in patients with stroke undergoing thrombectomy.
Methods: This was a multicenter, randomized, controlled, blinded adjudicated primary outcome study.

Background: Provisional single stenting strategy (PSS) is a default strategy for percutaneous coronary intervention (PCI) of unprotected left main distal bifurcation lesions (ULMD). Previous study reported that a bifurcation angle change (BAC) between end diastole and systole was associated with outcomes after PCI with double stent strategy (DSS) for ULMD. However, there are no data comparing outcomes after PCI with PSS versus DSS according the degree of BAC.

Background: Efficient recanalization of occluded cerebral arteries is crucial in the treatment of acute ischemic stroke. Double stent retrievers have shown the potential to enhance the rates of recanalization on the first pass. This study aims to evaluate the efficacy and safety of the double stent retriever technique and the predictors of achieving first-pass effect in patients with acute ischemic stroke.

Background: Mechanical thrombectomy using a double stent retriever technique has recently been described for the treatment of acute ischemic stroke, but its efficacy and safety are not well-established.
Purpose: The aim of this systematic review and meta-analysis was to evaluate reports of the use of a double stent retriever technique during the endovascular treatment of patients with ischemic stroke.
Data Sources: The PubMed, EMBASE, Web of Science, and Scopus databases were searched to identify all studies (clinical trials, cohort series, and case reports) investigating the utility of a double stent retriever technique for the treatment of stroke.
