Endoleak as a predictor of outcome after endovascular aneurysm repair: AneuRx multicenter clinical trial

摘要: Objective: The purpose of this study was to determine whether evidence blood flow in the aneurysm sac (endoleak) is a meaningful predictor clinical outcome after successful endovascular repair. Methods: We reviewed all patients Phase II AneuRx Multicenter Clinical Trial with stent graft implantation and predischarge contrast computed tomographic (CT) imaging. endoleak compared without endoleak. CT status before hospital discharge at 6, 12, 24 months determined by each center as well an independent core laboratory. Endoleak 1 month assessed duplex scanning examination or confirmation Results: Centers reported endoleaks 152 (38%) 398 on CT, whereas laboratory 50% these (P <.001). center-reported rate decreased 13% month. Follow-up extended 2 years (mean, 10 ± 4 months). One patient had rupture underwent open repair 14 months. This Type I but no subsequent follow-up times. There were differences between following measures: survival, rupture, surgical conversion, need for additional procedure patency, enlargement more than 5 mm, appearance new endoleak, migration. Despite higher identified laboratory, neither nor significantly related measures. Patients likely undergo endoleaks. experience year. However, there difference rate, primary secondary success Actuarial survival undergoing 96% year status. Primary 92% 12 88% 18 Secondary 94% Conclusions: presence absence scan does not appear predict using graft. Although identification finding may times indicate inadequate fixation, usefulness indicator procedural failure unclear. Therefore, who have undergone should be carefully followed up regardless (J Vasc Surg 2000;32:90-107.)
