The steerable-wire technique, combining a high-flow microcatheter and 0.025-inch guidewire, simplifies vessel selection in procedures like balloon-occluded retrograde transvenous obliteration (BRTO). This method offers a versatile alternative to traditional 0.035-inch guidewires.
Area of Science:
- Vascular Interventional Radiology
- Medical Device Technology
Background:
- High-flow steerable microcatheters have demonstrated utility in triaxial systems and complex vessel navigation.
- Previous research highlighted benefits in acute-angle bifurcations and coil-packing techniques.
- The specific application and advantages of a high-flow steerable catheter combined with a 0.025-inch guidewire remain underexplored.
