静脈ステント

Dedicated venous stents are designed specifically for venous anatomy with higher crush resistance, greater flexibility, and larger diameters than arterial stents. They accommodate the lower-pressure, higher-volume venous system and resist external compression.

Venous stenting is indicated for iliofemoral venous outflow obstruction from May-Thurner syndrome (iliac vein compression), post-thrombotic syndrome (PTS), chronic venous occlusion, and IVC obstruction including Budd-Chiari syndrome.

No. Veins need dedicated venous stents with larger diameters, high crush resistance to withstand external compression, and flexibility for the pelvic bend. Arterial stents are not built for the low-pressure, externally compressed venous environment, as in iliac vein compression (May-Thurner syndrome).
