Objective:
To evaluate the effectiveness and safety of endovascular treatment in solving symptomatic cerebral artery tandem lesions.
Methods:
From June 2012 to February 2014, 12 cases (24 lesions) with symptomatic cerebral artery tandem lesions were accepted for the endovascular treatment. The distributions of the tandem lesions were as follows: the common carotid artery and internal carotid artery (1 case), the internal carotid artery and the proximal of the carotid cavernous sinus segment (3 cases), the internal carotid artery and the distal of the carotid cavernous sinus segment (4 cases), the intracranial segment of internal carotid artery and middle cerebral artery M1 segment (2 cases), the first segment of vertebral artery and intracranial segment of vertebral artery (2 cases). All of these cases were treated from distal lesions to proximal lesions except for tandem lesions in the internal carotid artery and the distal of the carotid cavernous sinus segment in order to obtain better support. Tandem lesions were treated in the same operation with local anesthesia or general anesthesia. The procedures of the 12 cases retrospectively were analyzed and the peri-operation complications and responsibility region recurrent ischemic stroke incidents observed.
Results:
All tandem lesions were solved successfully all at once. There were no peri-operation complications or recurrent ischemic stroke incidents. There were no recurrent ischemic stroke incidents or stent restenosis cases in the follow-up.
Conclusion:
It is safe and effective for selective endovascular treatment in solving symptomatic cerebral artery tandem lesions at the same time, but we should take careful preoperative evaluation and improve the operation plan.
