there seems to be a renewed trend to go bevel down Do you do this and why?
When you have a dismorphic shunt, if i can describe structural defects in such a way, an attempt to safely secure the needle pushes the bevel too close to the vessel wall. That as you know will worsen QB in both needles. Flipping the needle positions the bevel facing the vascular lumen rather than the wall eliminating the QB problem and reducing potential complications.
