Procedures

Coronary angiography uses a catheter and contrast to define heart-artery anatomy. A stent may be placed when a blockage is likely to benefit.

Peripheral angiography defines leg-artery blockages. Angioplasty, atherectomy, or stenting may restore flow when expected benefit justifies treatment.

Catheter thrombectomy removes selected blood clots from deep veins or limb arteries. It is not necessary for every DVT or vascular occlusion.

Venous ablation and venous stenting solve different problems. Ultrasound and anatomic imaging help determine which treatment, if either, is appropriate.
