Abstract:
Objective To make a preliminary investigation and summary of the technique and efficacy of the novel intracranial stent, Enterprise, together with hydro-detachable coils for the treatment of very small intracranial wide-necked aneurysms (diameter<3 nun and body-to-neck ratio<1.5). Methods Six cases with very small intracranial wide-necked aneurysms were treated with Enterprise stents and hydro-detachable coils. In 5 cases the Enterprise stent was implanted to cover the neck of the aneurysm, which was followed by the introduction of a microcatheter into the aneurysmal sac through the stent mesh to stuff hydro-detachable coils in order to fill the aneurysmal sac. In the remaining case, the microcatheter was placed into the aneurysmal sac before the Enterprise stent was inserted to embolize the aneurysm. Postoperative follow-up was conducted for 3-6 months. Results The operation was successfully completed in all 6 patients, with the implanted stents being in right place. The parent arteries remained patency in all patients. No complications occurred. Complete occlusion of aneurysmal cavity was obtained in four cases, and the occlusion degree of the aneurysmal cavity above 95% was seen in 2 cases. After the procedure, all the patients recovered well. Neither rebleeding nor symptoms related to thrombosis occurred during a clinic follow-up of 3-6 months. Conclusion Endovasculur embolization with Enterprise stent together with hydro-detachable coils is a safe and effective method for the treatment of very small intracranial wide-necked aneurysms. However, its long-term effect needs to be further observed.
