Antecubital vein approach of retrograde transvenous obliteration using a steerable triaxial system for portosystemic encephalopathy

Steerable-wire technique using high-flow steerable microcatheter and 0.025-inch guidewire

“…Once the steerable tip is oriented, the dial stopper can be used to lock the steering dial to maintain the intended direction. Smaller microcatheters (1.7- or 1.9-Fr distal external diameter) are usually used for insertions; a high-flow steerable microcatheter has been reported to be useful as a triaxial system [1] , [2] , [3] . The benefits of steerable microcatheters in acute-angle bifurcation vessel insertions and a compact coil-packing technique using intentional folding with a bendable catheter tip have also been reported [4] , [5] , [6] .…”
