Technical aspects and midterm patency of iliac branched devices

Branched stent grafts were used to treat concomitant common iliac artery and thoracoabdominal aortic aneurysms. The right internal iliac artery underwent coil embolization.

A, Helical iliac side branch device. B, The arrows indicate the indwelling catheter.

Primary patency up to 22 months (central line) with standard error <10%. The peripheral lines depict the respective 95% confidence interval.

Secondary patency up to 22 months (central line) with standard error <10%. The peripheral lines depict the respective 95% confidence interval.

Illustration of the technical variations. A, The main device tip is shown inside the iliac artery while the exchanged Amplatz wire is snared from the contralateral approach. B, The 12F sheath is in place with the Amplatz wire still in place. This wire will be removed only after the bridging stent is in place. C, The Fluency and the Zilver stent are both in place. The uncovered stent is implanted 1 cm forward into the internal iliac artery, compared with the first, to avoid kinking.
