Purpose:
To report the early clinical experience with the Talent stent-graft system in the treatment of infrarenal aortic aneurysms.
Materials And Methods:
The study group comprised 15 males aged from 51-79 years. A bifurcated Talent stent-graft was implanted in 9 patients with type B or C aneurysms, a tube graft in 6 patients with a type A aneurysm. The stent-grafts were introduced via a surgical femoral cut-down, for a bifurcated graft a bilateral surgical access was needed. All procedures were performed as teamwork by radiologists and vascular surgeons under general anaesthesia in the angiography suite.
Results:
Primary and secondary technical successes were 80 and 86%, respectively. Technical failures were due to access site problems (n = 1; elective open repair), malpositioning of the prosthesis (n = 1; immediate conversion to open surgery), and primary distal leakage (n = 1; elective occlusion by means of distal stent-graft extension). One patient died 15 days after an uneventful stent-graft insertion (30-day mortality 6%). No complications were observed during a mean follow-up period of 7.8 months. The aneurysmal diameter decreased in 6 patients and remained unchanged in the others.
Conclusions:
The Talent system revealed satisfactory early results which are comparable to competitive stent-graft systems. An advantage of this stent-graft device is the availability in a wide range of dimensions. A major disadvantage is the large introducer system (french size 22-27).
