Use of fenestrated stent grafts in the treatment of juxtarenal aneurysms
AbstractObjective. This study aimed to analyze the results of using custom-made fenestrated stent grafts and physician-modified stent grafts.
Patients and methods. We retrospectively analyzed a total of 26 patients with unfavorable neck anatomy operated on in the Republican Cardiological Center of Ufa and the Federal State Budgetary Institution “Clinical Hospital” of the Administrative Directorate of the President of the Russian Federation. The patients were divided into 2 groups according to the method of fenestration formation: Group I receiving a custom-made device (n=12) and Group II receiving a physician-modified device (n=14).
Results. The average number of fenestrations in the first group was 2.7±0.6 per patient and in the second group 1.5±0.7 per patient. The success rate of implantation of the aortic component was 100% in both groups. In the first group, bridge graft implantation success was 96.3% (26 out of 27). Bridge graft implantation success in the second group was 95.4% (21 out of 22). Control MSCT revealed 2 endoleaks (16.7%) in the first group and 1 endoleak (7.1%) in the second group. In the first group, type IV endoleak was encountered in one case and type Ib endoleak in another.
Conclusion. The first results of using custom-made and physician-modified fenestrated stent grafts showed the data comparable with those from other clinics and indicated common complications and causes of repeat interventions.
