Usefulness of endovascular grafting for abdominal aortic aneurysm

: The purpose of this study was to determine the usefulness of endovascular grafting for abdominal aortic aneurysm (AAA) compared to conventional open repair. During the period from May 1998 through to April 1999, 16 patients (control group) with AAA underwent conventional open surgery and 6 patients (stent group) underwent endovascular grafting. Surgical data including operative time and intraoperative blood loss did not differ between the two groups. However, the postoperative parameters including the initiation of oral intake, the onset of flatus and the permission to walk were significantly sooner in the stent group than the control group. The postoperative changes of coagulopathy-fibrinolytic factor were comparable between the two groups. We conclude that the endovascular grafting is minimally invasive compared to conventional open surgery. In addition, there was no consumption coagulopathy in the endovascular grafting. However, it was necessary to develop new approach with new devices in order to perform endovascular grafting more safely.
