Acupoint Stimulation and Cranial Endovascular Treatment

Effect of Transcutaneous Electrical Acupoint Stimulation on Postoperative Complications After Cranial Endovascular Treatment

In this prospective randomized controlled trial, the subjects will be assigned to group transcutaneous electrical acupoint stimulation (TEAS) and group control (no intervention). The postoperative outcomes including NIHSS (National Institute of Health stroke scale) score, morbidity and mortality will be evaluated during hospital stay and by one year after surgery.

5. posterior circulation infarction
6. recurrence of an cerebral aneurysms after endovascular procedures or surgical clipping
7. severe abnormal coagulation function, severe liver and kidney function damage, or combined with heart and respiratory system failure
8. injury or infection of the skin around the acupoint area
9. participate in other clinical researchers within 3 months
10. history of neurological or psychiatric diseases
11. patients with implanted electrophysiological device
12. use of sedative or analgesics before surgery
