Venovo Venous Stent in Treating Iliac Vein Compression: A Single-Center Experience

Nicolas W. Shammas , MD, MS, FACC, FSCAI, FACP, FSVM;

James T. Torey , PA-C, PA;

We propose a dissection classification combining depth of injury from intima to adventitia with circumference of dissection. This classification exhibits six dissection grades (A1, A2, B1, B2, C1, and C2) as seen on IVUS (the “iDissection”...

We propose a...
