Endovascular treatment of symptomatic and ruptured abdominal aortic aneurysms.

AIM

To report our early experience with endovascular treatment of symptomatic and ruptured abdominal aortic aneurysms (AAA) using the Talent bifurcated stent graft.

PATIENTS-METHODS: From August 2003 to May 2007 nine patients with symptomatic AAA (sAAA) (two after previous endovascular repair and endoleak), and eleven patients with ruptured AAA (rAAA) (one with ruptured iliac aneurysm and one with spontaneous aortic rupture) were treated endovascularly. Seven bifurcated stent grafts, (six Talent), and two iliac extensions were implanted into the patients with sAAA, and nine bifurcated stent grafts (eight Talent) and two aorto-uniliacs were implanted into the patients with rAAA.

RESULTS

The deployment of the endovascular device in the intended location was successful in all patients. There was no conversion to open surgery. One patient with sAAA died after stroke and sepsis resulting in 11.1% 30-day mortality in this group. One required re-intervention for a type I endoleak before his discharge. Eight patients were discharged and during a follow-up period of 4-42 months (median 18 months) they have remained well. Two patients with rAAA died in the 30-day postoperative period. Thirty-day mortality was 18.1%. An unintended occlusion of one renal artery was performed. There were 9 survivors. During a follow-up period of 17-45 months (median 26 months) one more died of myocardial infarction.

CONCLUSION

Initial experience with endovascular treatment of patients with symptomatic or ruptured AAA, using the Talent bifurcated stent graft is promising. Bifurcated endografts can be implanted into patients with rAAA. A larger number of patients and longer follow-up is necessary to arrive at more reliable conclusions.
