Treatment With Ruptured Tiny Aneurysms Of Internal Carotid Artery By Stents Combined With Spring Coil

Objective:To summarize and analyze the clinical experience and technique of stents combined with coil embolization for ruptured tiny aneurysms of internal carotid artery(diameter 3 mm or less).Methods: Retrospective analysis was used to investigate 19 cases of tiny aneurysms of internal carotid artery who were treated with stents combined with spring coil between 2011.12 and 2014.12. Moreover, the intraoperative experience, the short and long term complications involved in intraoperative and postoperative therapy, the rate of embolism, the operation skills and prognosis were also explored.Results:(1) The 19 tiny aneurysms were embolized successfully with the success rate of 100%. The 14 aneurysms were treated with stents stable micro catheter technique(Jailing), the 3 aneurysms were treated with support semi release technology, the other 2 aneurysms were treated with the combination of stents stable micro catheter technology(Jailing) and micro catheter crossing support technology(Mesh);(2) the effects of intraoperative immediate embolism Raymond class was as follows: Grade 1(8 cases), Grade 2(6 cases), Grade 3(5 cases). No recurrence was observed by long-term follow-up, with the Raymond class: Grade 1(14 cases), Grade 2(3 cases), Grade 3(2 cases);(3) The 2 cases occurred intraoperative ruptured hemorrhage. However, no adverse prognosis was appeared owing to immediate treatment; One cases showed cerebral vasospasm, resulting in transient ischemic neuronal damage in postoperative hospital stay.Conclusion: Stents combined with coil embolization is one of the common and effective strategy for the treatment with ruptured tiny aneurysms of internal carotid artery. Despite the existence of certain complications rates, the total curative effects of this method are worthy of recognition.
