Background: Our aim was to describe our experience of the multilayer flow modulator (Cardiatis, Isnes, Belgium) used in the treatment of renal artery aneurysms.

Case report: A female patient, aged 42 years underwent treatment of a renal artery aneurysm using the multilayer flow modulator. Contrast-enhanced computed tomography revealed a 23.9 mm type III renal artery aneurysm at the bifurcation of the upper and lower pole vessels, with four side branches. Follow up was assessed by postoperative computed tomography scan at 6 and 19 months postoperatively. There were no immediate postoperative complications or mortality. A normal estimated glomerular filtration rate of > 90 ml/min, which was recorded preoperatively, decreased to 77 ml/min on the day of surgery, and returned to > 90 ml/min 1 day postoperatively. The aneurysm initial decreased in size by 23% at 6 months, and by 16% at 19 months. Overall aneurysm shrinkage was 36% (8.6 mm), with all four side-branches remaining patent throughout follow up.

Conclusion: The MFM may provide less operative trauma for patients where complex surgical intervention is the only other feasible treatment option. Longer follow-up, a larger sample size, and comparative studies are required to prove the efficacy of this emerging technology.
