RESULTS OF RE-ENDOVASCULAR INTERVENTION FOR TYPE 1B ENDOLEAKS IN PATIENTS WITH ENDOVASCULAR ABDOMINAL AORTIC ANEURYSM
Main Article Content
Abstract
Background: Endovascular abdominal aortic aneurysm (EVAR) treatment is a standard and fighting open surgery. Endoleaks of complications after aneurysm treatment are encountered in 15-21% of cases[1],[2]. Most are resolved by endovascular intervention to prevent blood flow into the aneurysm, causing enlargement and later rupture. Type 1B endoleaks are seen in cases where the blood goes out into the sac at the distal landing zones of the stent graft. The reintervention alone or combined with occlusion with the coil, amplatzer, or branched devices is still attractive to many authors. Methods: Retrospective description of case series. Results: The study involved participants with an average age of 70.4 ± 8.2 years, mostly male. Hypertension and smoking were the most common risk factors, accounting for 93.3% and 73.3% of the sample, respectively. Among the risk factors for type 1B endoleaks, a short iliac sealing zone and tortuosity iliac axes were the most prevalent, accounting for 66.7% and 93.3% of the sample, respectively. Using a cover stent with internal iliac artery blockage accounted for 53.3% of cases while using a cover stent alone accounted for 33.3%. The technical success rate was 100%, with only 6.7% of complications recorded as hematoma and 13.3% as acute renal failure. During the follow-up period, the rate of no endoleak recurrence reached 86.7% of the sample. Conclusion: The study shows that re-intervention to treat type 1B endoleaks in patients with EVAR of abdominal aortic aneurysm is performed safely and effectively, with few complications and low recurrence.
