Abstract: ［Abstract］ Objective〖HTSS〗〓To analyze the clinical efficacy of double micro catheter technique in patients with endovascular embolization and its effect on cognitive function of patients.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓Eighty cases of intracranial wide necked aneurysms were divided into the observation group and the control group randomly, and each group had 40 cases. The observation group was treated with endovascular embolization through double micro catheter technique, while the control group was treated with selfexpanding stent(LEO stent) and coil embolization. The patients were followed up for one year, and the clinical efficacy and postoperative complications were observed. The patient′s cognitive function was evaluated by the MiniMental State Examinatlon(MMSE) 1 years after the operation.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓The total effective rate of the observation group was 97.5%, significantly higher than 77.5% of the control group(P＜001). The MMSE score of the observation group and it′s 5 dimensions of attention, memory, orientation, language ability and memory ability were significantly higher than those in the control group(P＜001). The total incidence of postoperative complications was 5% in the observation group and 15% in the control group, and the different was not significant(χ2=1.250， P＞005).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓The clinical effect of double micro catheter technique for treating endovascular embolization is remarkable, and it can improve the postoperative cognitive dysfunction. It has higher clinical value.
