The evolution of Z stent-based stent-grafts for endovascular aneurysm repair: a life-table analysis of 7.5-year followup.
(2002) In Journal of the American College of Surgeons 194(1 Suppl). p.74-78- Abstract
- BACKGROUND: The purpose of this study was to analyze the impact of stent-graft design and operator skills on outcomes after endovascular abdominal aortic aneurysm repair. STUDY DESIGN: One hundred sixty-four patients (mean age 71 years) underwent stent-graft repair. Patients were treated with four different types of stent-graft: first-generation (n = 58) and second-generation (n = 17) Ivancev-Malmö monoiliac stent-grafts (IM I and IM II, respectively) combined with femoral-femoral crossover, Chuter bifurcated stent-graft (n = 15), and the Zenith stent-graft (n = 74). Patients underwent digital subtraction angiography and contrast CT preoperatively and were then followed with CT scans postoperatively. Recently, followup was changed to CT... (More)

Patients underwent digital subtraction angiography and contrast CT preoperatively and were then followed with CT scans postoperatively. Recently, followup was changed to CT scanning at 1 month and 1 year postoperatively and annually thereafter. Ultrasonographic duplex scanning substitutes in the remaining followup. Changes in aneurysm diameters and occurrence of endoleaks were recorded. Short- and midterm mortality and complications and postoperative secondary interventions were recorded, and life-table analysis for intervention-free stent-graft survival was calculated. RESULTS: Immediate and late conversions and 30-day mortality were reduced for second- (IM II and Zenith) compared with first-generation stent-grafts (IM I and Chuter). Stent-graft migrations occurred only with the IM I and Chuter stent-grafts. Type I endoleak was significantly more common in first-generation stent-grafts. First-generation stent-grafts required significantly more secondary interventions than second-generation stent-grafts up to 30 months postoperatively. CONCLUSION: Enhanced stent-graft design has improved the probability of stent-graft success after endovascular abdominal aortic aneurysm repair. Better technical skills and increased use of intraoperative adjunctive procedures may also have contributed to improved results. (Less)
