Objectives: In this study, we present our early and postoperative first-year results of instructions for use-compatible elective endovascular
abdominal aneurysm repair via the Lifetech Ankura™ abdominal aortic aneurysm (AAA) stent graft and evaluate the efficacy,
conformability, and durability of the endograft.
Patients and methods: Between January 2018 and December 2019, a total of 100 consecutive patients (95 males, 5 females; mean age
71.5±9.3 years; range, 56 to 92 years) with an elective infrarenal AAA treated using the Lifetech Ankura™ stent graft in four centers were
retrospectively analyzed. All the patients were compatible with the instructions for use. All the patients underwent angiography, first-month
computed tomography, and postoperative one-year follow-up.
Results: There was no early mortality or conversion to open surgery. Technical success was 100%. The mean procedural time was 126 min
including anesthesia, and the mean fluoroscopy time was 12.4±2.96 min (range 10.3-14.5). The type of anesthesia was general anesthesia
in 90% patients. The mean amount of the opaque material used was 45.0±9.8 mL. The mean length of stay in the intensive care unit and
hospital was 2.3±0.9 and 3.2±1.9 days, respectively. There were two type Ib endoleaks for native iliac artery dilatation and five type 2
endoleaks with no sac enlargement in the first postoperative year.
Conclusion: For the instructions for use- compatible patients, the Lifetech Ankura™ AAA stent graft yields successful results, and also is
effective for the early period and durable for the first postoperative year.
Key words: Endograft, elective infrarenal abdominal aortic aneurysms, instructions for use.
