Abstract

INTRODUCTION: The evaluation of health technologies plays a crucial role in modern healthcare, providing a reliable foundation for making informed decisions regarding the reimbursement of new medical devices, drug therapies, and diagnostic approaches. A review has been conducted to outline the benefits of implementing the innovative self-expanding laser-cut stent technology in the treatment of cerebral aneurysms. 

OBJECTIVE: The aim of this study is to assess the benefits, safety, and efficacy of using a self-expanding laser-cut stent for the treatment of cerebral aneurysms, which represents the most common endovascular approach for managing these conditions. 

MATERIALS: A documentary research method was employed, including a systematic review of literature from electronic databases such as PubMed, Scopus, Web of Science, and ResearchGate, using specialized software to evaluate existing risks, safety, and efficacy in the application of a self-expanding laser-cut stent for cerebral aneurysm treatment. The procedural aspects, types of complications, clinical outcomes, and aneurysm occlusion rates with self-expanding laser-cut stents were retrospectively analyzed. 

RESULTS: Studies indicate that embolization devices utilizing self-expanding laser-cut stents achieve a complete occlusion rate of 83.3% and a favorable occlusion rate of 97.7% in a one-year angiographic study of 174 aneurysms, with minimal morbidity and no mortality associated with the intervention. This suggests that the treatment is a safe and effective approach for intracranial aneurysms. Based on findings from multiple independent studies, treatment with the DED stent represents a reasonable, safe, and effective alternative. 

CONCLUSION: The data from various studies support endovascular techniques as a safe and effective therapeutic method for treating cerebral aneurysms, even in the acute phase. The identified clinical evidence demonstrates the added value of self-expanding laser-cut stents for embolization as a safe and effective option for treating cerebral aneurysms by redirecting blood flow when other endovascular or neurosurgical techniques are not viable.
