Abstract:

Objective

To evaluate the safety,middle or short-term effect and indication of the endovascular treatment for ischemic stroke patients with extracranial carotid stenosis.

Methods

The clinical data of Affiliated Hospital of Qingdao University from June 2009 to December 2014 with percutaneous transluminal angioplasty and stenting for extracranial carotid artery stenosis cases were retrospectively reviewed，from which 106 cases of ischemic stroke in the past were selected to study.And summarized the information including operation opportunity,operation experience,serious complications such as cerebral hemorrhage and secondary ischemic stroke.Their clinical features，method of treatments and prognosis were analyzed Specially.

Results

The placement of 106 cases with 120 stents was satisfaction.Cerebral hemorrhage occurred in 3 cases;thrombosis following stent placement in 2, hypotension and bradycardia in 6, vasospasm in 11, gastrointestinal stress bleeding in 1, restenosis occurred in 8,no cerebral infarction occurred after operation.Apart from one case of death cerebral hemorrhage, 8 of restenosis. The remaining 97 patients, middle or short-term results were satisfactory.Eighty-three cases were followed up for 3 months to 5 years,no ischemic attack and cerebral infarction occurred.

Conclusion

The satisfactory effect and safety were achieved in the therapy of carotid stenosis by percutaneous transluminal angioplasty and stenting, Angioplasty and stenting may improve the cerebral hemodynamics of patients with severe/moderate internal carotid artery stenosis. it is suitable forprevious ischemic stroke patients; We must be individualized to more carefully assess these patients'surgical risk,strictly adhere to the indications of surgery，and general measures is the key of preventing the complications during the perioperative period.
