Minimally invasive treatment for supra-renal abdominal aorta lesions / 中国普通外科杂志

ABSTRACT

Objective To evaluate endoluminal stent-grafting for diseases of supra-renal abdominal aorta. MethodsWe retrospectively analyzed the clinical data of 42 cases with supra-renal aorta lesions from July 2000 to December 2004, including 32 cases of dissection aorta aneurysm, 7 cases of thoracic aortic aneurysm, and 3 cases of thoracic pseudoaneurysm. ResultsOne died in perioperative period (2.4%). Endoleaks occurred in 8 cases (19.1%) after the deployment of the first stent. Among them, leaks were sealed in 3 cases by balloon dilatation, the remaining 2 cases were treated by the placement of additional stenting-graft, 3 cases were treated conservatively. Patients were followed-up for 1～51 months, with a mean of 16 months. One (2.4%) died during the follow-up. Endoleak disappeared in 3 cases. ConclusionMinimally invasive endoluminal grafting is a relatively safe and effective means for the treatment of high-risk aortic lesions, though the long-term result remains to be proved.
