Single or staged endovascular stent-graft repair for aortic dissection with multi-tears / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the single or staged endovascular stent-graft repair for aortic dissection with multi-tears.</p><p><b>METHODS</b>The stent-grafts were inserted through the femoral artery to seal the tears of dissection.</p><p><b>RESULTS</b>Between January 2001 and June 2004, 8 patients with aortic dissection underwent stent-graft placement. There were 5 tears in one patient, 4 tears in two patients, 3 tears in two patients and 2 tears in three patients. There were 11 tears located at descending thoracic aorta, 11 at abdominal aorta and 4 at iliac artery. Six patients underwent operation in single stage, and 2 in staged maneuver. Total 23 stent-grafts were used, including 20 straight type grafts and 3 bifurcated grafts. Placement of the stent-graft was technically successful in all patients. Follow-up with CT or MRA examination after 3, 6, 12 and 24 months postoperatively showed the dissection disappeared with thrombosis in the false lumen, no endoleak occurred. All patients survived to present.</p><p><b>CONCLUSION</b>Single or staged endovascular stent-graft repair is a promising, safe and effective procedure for aortic dissection with multi-tears.</p>
