A Case of Early Limb Stenosis after Endovascular Abdominal Aneurysm Repair with the Endurant Stent Graft System

Endovascular abdominal aneurysm repair (EVAR) relies on the quality of the proximal and distal landing zone. Reinterventions are higher in patients with suboptimal landing zone. The study aimed to evaluate reintervention rate after endovascular treatment of an aorta-iliac aneurysm using the flared iliac limbs.The retrospective study included 179 patients treated with EVAR at a single university hospital institution from January 2011 to January 2014 of which 75 patients (42%) were treated with flared iliac limb stent graft and 104 patients (58%) were treated with a nonflared iliac limb stent graft. There were 165 male patients (92%), mean age was 75.8 ± 6.6 years.Thirty-six patients underwent secondary treatment accounting for overall reintervention rate of 20%. Endoleak type 1b occurred in 13 patients (7%), followed by endoleak type 1a in six patients (3%). Endoleak type 2 occurred in seven patients (4%) requiring the treatment due to abdominal aortic aneurysm (AAA) enlargement, endoleak type 3 in three patients (2%), and leg stent graft thrombosis in seven patients (4%). In 143 patients (80%), there were no secondary interventions during the follow-up period. Reintervention due to endoleak type 1b was statistically significantly higher in a flared iliac limb group (p < 0.02) with the rate of 7.2% compared with 1.9% rate in nonflared iliac limb group. The mean follow-up was 44.3 ± 20.4. Overall mortality was 33%.Flared iliac limb with a distal diameter of ≥ 20 mm, show a higher rate of iliac limb reintervention in a follow-up period due to endoleak type 1b.

[b]Background:[/b] The aim of our study was to present an innovative endovascular technique – the Aptus™ Heli-FX™ EndoAnchor™ system com bined with the Endurant Stent Graft cuff used as a method of choice for the patient in a very poor general condition with symptomatic abdominal aneurysm and a post-EVAR type IA endoleak.[b]Case study: [/b]An 85-year-old male patient, was operated on in March 2016 with endovascular aneurysm repair (EVAR) of a 9.3 cm in diameter ruptured abdominal aneurysm (RAA), accompanied by disturbance to the coagulation profile (prolonged INR of 3.3 because of anticoagulant treatment with Rivaroxaban due to atrial fibrillation). 9 months later, he developed a severe abdominal pain and was urgently referred to the Vascular Surgery Department, at the John Paul II Hospital, Kraków. The Angio-CT xamination revealed the type IA and II endoleaks and a recurrence of the rupture symptoms. He was successfully operated on using an innovative endovascular repair system, the Aptus™ Heli-FX™ ndoAnchor™ system with a combination of other endovascular procedures, such as Endurant Stent Graft cuff implantation. [b]Conclusions:[/b]The innovative endovascular repair system, Aptus™ Heli-FX™ EndoAnchor™ together with the Endurant Stent Graft cuff was successfully used in the treatment of the patient. This technique prevented him from developing serious complications or even death and gave him a much better quality of life in comparison with open surgery repair.

Aneurysm Repair

The aim of the study was to evaluate the anatomic suitability for endovascular abdominal aneurysm repair (EVAR) according to instructions for use (IFUs) of three commercially available bifurcated stent graft devices and explore the possible benefits of low-profile delivery systems. Computed tomography scans of 241 patients with abdominal aortic aneurysm (AAA) were evaluated for suitability of Zenith Flex®, Gore Excluder® and Endurant® bifurcated stent graft systems according to their IFUs. The most common exclusion criteria and possible benefits of smaller diameter delivery systems were analyzed. When choosing the most suitable graft model for each patient, the overall suitability was 49.4%. By brand, the suitability was 28.6% for Zenith®, 25.7% for Gore Excluder® and 48.1% for Endurant®. By step wise accepting iliac diameters of ≥6 mm, ≥5 mm and ≥4 mm the overall suitability increased to 56.7, 58.9 and 60.2%, respectively ( P < 0.001). Diameters below 4 mm had no additional effect on suitability as combinations of other anatomical features, with or without narrow iliacs, accounted for the remaining excluding factors. In conclusion, Less than half of patients with AAAs are suitable for EVAR according to current IFUs. Low-profile delivery systems may allow for endovascular treatment in up to 60% of patients.
