Venous Obstruction
Venous obstruction occurs when a vein becomes narrowed or blocked, restricting blood returning to the heart. Causes include blood clots, scarring, external pressure or previous catheter placement.
Symptoms
Swelling, heaviness, pain, skin changes or enlarged visible veins. Symptoms depend on the location and severity of the blockage.
How interventional radiology treats it
Venoplasty uses a balloon to widen the narrowed vein. A stent may be inserted to keep it open. In selected cases, catheter-based clot removal may also be considered. Ultrasound, CT or venography helps identify the blockage. Follow-up checks whether blood flow remains adequate.
Whether this treatment suits you depends on your scans and overall health. A consultation is the first step.
