Fig 3 — DSA images of the procedure. A 9Fr catheter balloon is inflated and fixed near the entry to the shunt; 5Fr catheter and the guidewire are advanced into the shunt (A). A 5Fr balloon is inflated and fixed against the vessel wall; 9Fr balloon is deflated and its catheter is advanced into the shunt (B). A 5Fr catheter with deflated balloon is slowly advanced forward (C). A 5Fr balloon is inflated, and the 9Fr catheter is moved closer to the 5Fr balloon; this unwinds the shunt, which now appears as a straight vessel (D). Microcatheter and the guidewire are advanced through the marginal vein (E).
