Parallel Endograft (Sandwich Technique) to Treat Aorto-Iliac Aneurysms; Faesibity and Short-Term Outcomes
Background: Up to 20-30% of Abdominal Aortic Aneurysms (AAA) have concomitant common iliac artery
aneurysms that continues to be troublesome is their management keeping in mind the possible clinical
significance of sacrificing the hypogastric arteries (HGAs) for effective AAA treatment. Method: Parallel
endograft (sandwich technique) was offered to patients with abdominal aortic aneurysm associated with
unilateral or bilateral common iliac artery (CIA) aneurysms with or without hypogastric artery (HGA)
aneurysm presented at vascular surgery department, Cairo university hospitals between March 2014 and
September 2016. Results: 5 patients underwent parallel endograft endovascular aneurysm repair (PGEVAR) for infra-renal abdominal aortic aneurysms associated with unilateral or bilateral common iliac
with or without hypogastric artery aneurysms. Four patients were males (80%), presenting a median age of
77 years (range 66-88 years). The median length of the procedure was 105 minutes (80-210 minutes),
fluoroscopy time minutes (15-50 minutes), IV contrast dose 85 mL (50-180 mL), and average estimated
blood loss 55 mL (30-400 mL). A total of 6 self expanding covered stents (4 Fluency stents & 2 Viabhan
stents) were used with 6 SMART Control self-expanding bare-metal stents for relining to attain better HGA
endograft apposition and prevent compression by the ILE. One patient presented with immediate postoperative right arm weakness due to cerebral infarction. Another patient developed postoperative severe
respiratory insufficiency due to severe chronic obstructive pulmonary disease. The overall hospital stay
was at a median of 3 days (2-20 days). Neither type I nor type III endoleaks were detected at follow up.
Only one case showed mild aneurismal sac enlargement at 6 month follow up due to persistent type II
endoleak .Follow-up CT and Duplex scans showed patency of all Viabhan and Fluency grafts without instent re-stenosis at a median follow-up of 6 months (range 3-10 months). Conclusion: our limited series
indicates that the sandwich technique is a technically safe and effective technique for the preservation of
HGA circulation. In our opinion, it has the advantage of expanding the applicability of EVAR for AAA with
complex iliac artery anatomies. However, further studies with more long-term data are required to confirm
the safety and efficacy of the sandwich technique.
