Background: To present a technique of sheath supported contralateral limb gate (CLG) cannulation of modular bifurcated stent-graft in endovascular abdominal aortic repair. Materials and methods: After totally percutaneous bilateral femoral access, the 9F introducer sheath is exchanged to a 30 cm 12 fr introducer sheath over a stiff wire contralateral to the intended main stent-graft insertion side and advanced into the aorta below the lowest renal artery. Parallel to the stiff wire within the sheath an additional standard J-tip guidewire with a 5 fr Pigtail angiographic catheter is advanced to the level of the renal arteries. After main body deployment, the 12 fr introducer sheath and J-tip wire with pigtail catheter are retracted until the CLG opening level, maintaining the stiff "buddy" wire in position to support the 12 fr sheath, maintaining its distal opening close to the contralateral gate opening to achieve easy cannulation. Results: Retrospective analysis of video archive from July 2016 to February 2018 evidenced 55 recorded EVAR cases. All CLG cannulations were obtained with Standard J-tip or Terumo Glidewire wires and with Pig-Tail or Berenstein catheters. Technical success was 100 %. Mean fluoroscopy time to accomplish CLG cannulation was 37.6 33 (range 1-105) seconds. The aortic carrefour angulation on coronal axis strongly correlates with cannulation time p = <.001, with longer cannulation time for higher carrefour angulations on coronal axis (Pearson correlation coefficient 0.47). Conclusions: The use of 12 fr sheath with parallel wire introduction technique, appears to be a safe and reliable tool to facilitate CLG cannulation during EVAR procedures.
