Abstract

Objective To investigate the clinical applications of sandwich technique according to area calculation in endovascular aneurysm repair of patients with aorta and iliac artery lesions.Methods Six patients with aortoiliac artery disease confirmed by CT were treated using sandwich technique according to area calculation.The diameter of the main stent and two branches stents were chosen according to the area calculation.Technical success rate,patency of the stent graft and complications were observed.Results Technical success rate was 100％ (6/6),and no complications occurred in all the 6 patients.The clinical symptoms were significantly improved.Gutter endoleak was found in 1 patient 2 months after the procedure,and was managed by coil embolization successfully.No endoleak occurred in other patients during follow-up of 6-31 months.Conclusion For patients with special anatomy of aorta and iliac artery lesions,the application of area calculation in the sandwich technique provides a feasible approach in choosing the matching size of the main body stent and two side branches stents.
