Abstract:
Objective To analyze the etiology of cerebral ischemic complications occurring in perioperative period of interventional therapy for intracranial aneurysms,and to discuss its prevention and treatment.Methods From January 2011 to March 2015,a total of 1106 patients with intracranial aneurysms underwent interventional therapy at the First Affiliated Hospital of Zhengzhou University,China.Among the 1106 patients,48 patients developed cerebral ischemic complications;their clinical data and the imaging materials were retrospectively analyzed.The factors associated with complications,the effective therapeutic scheme and the clinical preventive methods were discussed.Three months after the treatment,the recovery of neurological function was assessed with modified Rankin Scale (mRS).Results The causes of ischemic complications were,in order of decreasing frequency,cerebral vasospasm/unable elimination of microemboli (n=19),thrombus (n=16),impaired blood flow of adjacent perforating or distal vascular branches caused by embolization (n=6),intra-procedural hypotension (n=4) and cerebral edema (n=3).Combined treatments,including integrated anticoagulation,anti-platelet aggregation,anti-vasospasm,medication of elevating blood pressure,endovascular intervention,etc.were adopted.The patients were followed up for 3 months.Thirty-four patients (70.8％) obtained a mRS of ≤2 (no serious sequelae),and mRS＞2 (poor prognosis) was seen in 14 patients (29.2％).Conclusion The etiology of cerebral ischemia occurring during interventional treatment of intracranial aneurysms is complicated.It is necessary to take useful measures such as individualized anticoagulation,anti-platelet aggregation,anti-vasospasm,etc.during perioperative period of interventional therapy.The procedure-related complications can be effectively treated with interventional therapy and reliably prevented by careful and skilled surgical manipulation.
