Comparison of Long and Short Stent Retrievers in Mechanical Thrombectomy for Acute Ischemic Stroke Due to Large Vessel Occlusion: A Systematic Review and Meta-Analysis

Key Points

• This research aims to compare the effectiveness of long and short stent retrievers in mechanical thrombectomy for acute ischemic stroke.
• Conducted a systematic review and meta-analysis of existing studies on stent retrievers.
• Analyzed angiographic efficacy and complication rates associated with long versus short stent retrievers.
• Evaluated how thrombus burden and vascular anatomy influence stent selection.
• Long stent retrievers showed improved angiographic efficacy, particularly enhancing first-pass reperfusion.
• Overall complication rates did not increase with the use of longer stent retrievers.
• Recommendations include tailoring stent use based on thrombus characteristics and vascular anatomy.
