#vascular lumen

• Angioplasty — A minimally invasive surgical intervention within interventional radiology and cardiology, used for the widening, restoration, or structural reconstruction of the lumen of a narrowed or occluded blood vessel. The procedure is well-defined by introducing a catheter equipped with an inflatable balloon at its tip, which is inflated at the stenosis level to dilate the vascular wall, frequently accompanied by the permanent placement of a metallic stent to maintain circulatory patency.
• Angiotomy — A specialized surgical intervention consisting of the incision, cutting, or operative opening of the wall of a blood vessel (artery or vein). This well-defined structural procedure is utilized as an essential initial step in interventional radiology and vascular surgery to allow the introduction of catheters, the extraction of thrombi (thrombectomy), or the direct exploration of an obstructed circulatory lumen.
