Transluminal balloon angioplasty, also known as transluminal balloon venoplasty, is a minimally invasive procedure aimed at treating occlusions in veins. This technique involves the use of a balloon catheter to open narrowed or blocked veins, thereby restoring normal blood flow. The procedure begins with the preparation of the skin over the access vein, followed by the puncture of the vein with a needle to facilitate access. A sheath is then placed to allow for the introduction of other instruments. A guidewire is inserted and navigated through the access vein into the occluded segment of the vein. Subsequently, a catheter equipped with a balloon tip is advanced over the guidewire to the site of the blockage. Once positioned, the balloon is inflated, which compresses the plaque against the walls of the vessel, effectively widening the vein. This inflation may be repeated multiple times to achieve optimal results. After the angioplasty, the catheter is exchanged for a guidewire, and a venography catheter is introduced to assess the success of the procedure. A contrast agent is injected to perform a completion venogram, ensuring that the vein is patent and that blood can flow freely. Finally, the venography catheter is removed, and pressure is applied to the puncture site to prevent bleeding, followed by the application of a pressure dressing to secure the area.
