Background And Purpose: Thrombectomy in distal, medium vessels is a topic of increasing interest. To date, there are few studies focused on performance of ≤5F catheters in medium vessels. The purpose of this study is to compare the performance of the 3F, 4F, and 5F MIVI Neuroscience Q Catheters versus Penumbra 3F, 4F, and MicroVention Sofia 5F Catheters.

- The study investigates the use of contrast-enhanced cone beam CT (CE-CBCT) for better visualization of the distal part of clots during mechanical thrombectomy (MT) for ischemic strokes, as conventional imaging methods face challenges in this regard.!* -
- Results showed that CE-CBCT significantly outperformed traditional imaging techniques like 3D rotational angiography (3DRA) and digital subtraction angiography (DSA) in visualizing the distal edges of clots and the arteries beyond the blockage.!* -
- Enhanced visualization with CE-CBCT correlated with improved MT effectiveness, demonstrated by higher rates of successful clot removal and better collateral blood flow, indicating its potential value in stroke treatment.!*
Background: Studies investigating endovascular therapy in vertebro-basilar stroke have led to controversial results in the past, but recent randomized trials seem to show an effectiveness superiority of endovascular therapy versus best medical treatment. However, uncertainty remains concerning many aspects of thrombectomy in acute basilar artery occlusion, notably technical considerations. This study compared the first-pass effect of direct thromboaspiration and combined thrombectomy in the setting of distal basilar occlusion.

We aimed to evaluate if the microwire push forces could extrapolate information on clot consistency and extension before MTB, based on clot mechanical properties.
Methods: We measured in vitro the forces exerted on the proximal extremity of the guidewire during the advancement and retrieval of the guidewire through clot analogs of different compositions.
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.
