Intravascular Ultrasound-Guided, Lithotrispy-Facilitated Angioplasty for Treating a Heavily Calcified Renal Artery Stenosis

02/28/2024
Video 1. Renal artery angiogram. Critical ostioproximal left renal artery stenosis. 
Video 2. Initial Shockwave intravascular lithotripsy (IVL). The Shockwave IVL balloon remained unexpanded after first therapies.
Video 3. Final Shockwave intravascular lithotripsy (IVL). The Shockwave IVL balloon expanded fully after the fifth Shockwave therapy.
Video 4. Stent positioning.  A 6 x 18-mm Express stent (Boston Scientific) is positioned across the left renal artery stenosis lesion with minimal protrusion in the aorta.
Video 5. Stent deployment. The above stent is deployed at 16 atm.
Video 6. Stent post-dilation. The deployed stent’s proximal part is ‘flared’ with the stent’s balloon.
Video 7. Final renal artery angiogram. Excellent final angiographic result after left renal artery stenosis intervention. 
Video 8. Renal artery angiogram 7 months later. Patent stent without restenosis.
