Abstract:
Objective To evaluate the efficacy and mid-term follow-up results of endovascular treatment with Willis covered stent for traumatic pseudoaneurysms located in the internal carotid artery (ICA).Methods ICA angiogmphy was performed in 38 patients with traumatic brain and neck injury.Of the 38 patients.13 delayed traumatic pseudoaneurysms were found.All the pseudoaneurysms were treated with Willis covered stents.Follow-up angiography was performed at 1,3,6 and 12 months after the procedure,and the results were categorized as complete or incomplete occlusion.Clinical manifestations were graded as full recovery,improvement,unchanged and aggravation.Results Willis covered stent placement was technically successful in all traumatic pseudoaneurysms.No procedure-related complications occurred.The initial angiographic results showed a complete occlusion in 9 patients,and an incomplete occlusion in 4.The angiographic follow-up within 3-12 months exhibited a complete occlusion in 12 patients and the parent arteries remained patency in all patients.The clinical follow-up observation demonstrated that full recovery wag obtained in 11 patients,clinical improvement in one,and unchanged condition in one.No morbidity or mortality occurred.Conclusion Willis covered stent implantation iS a feasible and practical treatment for traumatic pseudoaneurysms located in the ICA.This technique can well preserve the parent artery with excellent therapeutic results.
