Abstract

Among assisted techniques, balloon-assisted coiling is commonly used but has limitations such as flow interruption and thrombotic risk. The temporary Comaneci stent is an innovative advancement that stabilizes microcatheters, protects the aneurysm neck, and maintains blood flow. This study evaluates the initial outcomes of the Comaneci stent in endovascular coil embolization. Materials and Methods: A retrospective study was conducted at the Radiology Center, Hanoi Medical University Hospital (April 2022–August 2024), involving 13 patients with wide-neck intracranial aneurysms (dome-to-neck ratio <1.2 or neck width greater than the parent artery diameter), including both emergency and selective interventions. The Comaneci stent (Rapid Medical, Israel) was used in combination with coils. Results: 13 patients (mean age: 59.8 years) were successfully treated. Aneurysm locations were primarily in the posterior communicating artery (7/13). Complete aneurysm occlusion was achieved in 100% of cases (Raymond-Roy grades 1 and 2). Mean aneurysm size: 9.58 mm (largest: 22 mm, smallest: 3 mm); mean neck width: 3.94 mm. Two patients experienced minor complications (coil protrusion without affecting flow). No mortality or morbility occurred. Conclusion: The temporary Comaneci stent is a safe and effective adjunct in endovascular coil embolization, particularly for wide-neck aneurysms. This technique overcomes limitations of balloon assistance and permanent stents while eliminating the need for prolonged antiplatelet therapy. The study results highlight the potential for widespread clinical application.
