Article Title: Utility of the turn-back supporting technique using a steerable intermediate catheter: illustrative case

doi: 10.3171/CASE24467

Figure Lengend Snippet: A distal access guiding catheter was cannulated into the isolated SSS from the left internal jugular vein ( A ). An SIC was then inserted and manually steered into a hairpin shape inside the sinus ( B ). The SIC was turned toward the venous pouch, and a microcatheter was successfully navigated into the pouch, resulting in complete obliteration with two coils ( C and D ). Additional sinuplasty was performed using a percutaneous transluminal angioplasty balloon and a self-expanding stent ( E ), restoring normal venous return and improving venous flow disturbance ( F and G ). No recurrence was observed on follow-up MR angiography ( H ).

Article Snippet: In addition, a sinuplasty was performed using a percutaneous transluminal angioplasty balloon with a diameter of 8 mm/40 mm and an 8-mm-diameter/29-mm-long Carotid Wallstent (Boston Scientific) in the occluded left TS.
