弓部大動脈瘤患者に対するオープンステント法を用いた弓部置換術の検討

抄録

We conducted a retrospective study on the results of 10 patients with distal arch aneurysm undergoing total arch implantation with open stent-placement(OSP) in comparison with 17 patients with distal arch aneurysm undergoing conventional total arch implantation(TAI). In the OSP group, postoperative intubation time and ICU stay were shorter than those of the TAI group, and there were no left recurrent nerve injury or left phrenic nerve injury. But there were one with spinal cord infarction and one with endoleak in the OSP group. While a new total arch implantation method with a stent graft offers less invasiveness than a conventional surgical method, this method may have a possibility of severe complica-tions. Consequently, this open stent-placement method must be indicated for only a high risk patient.
