Vascular and Interventional Radiology Procedures
Interventional procedures can also be applied to increase the flow of blood in a particular vessel. Four type of procedures are used: percutaneous transluminal angioplasty (PTA), vascular stent placement, intravascular thrombolysis, and intra-arterial infusion of vasodilator.
During angiographic procedures, contrast agents are used in imaging to obtain a clear representation of blood vessels and soft tissue. The contrast agent is injected intravenously and carried through the bloodstream, to all the branches of the vascular tree.
In an angiographic procedures, a balloon tipped catheter is placed into an area of blockage and inflated to stretch open the vessel and push the plague outward against the artery wall. The balloon is then deflated and removed from the body. Usually after a balloon is used, a stent is placed. Sometimes when a blockage is very hard and calcified, the physician may use a device called rotational atheretomy.
Using imaging guidance, an inflatable balloon mounted at the tip of catheter is inserted through the skin into the fistula and advanced to the blockage.
Endovenous Laser Treatment Evlt
This procedure of Endovenous Laser Treatment is recommended when the varicose veins are particularly large and cannot be treated with Sclerotherapy. The alternative treatment of stripping the varicose vein, Endovenous Laser Treatment, is revolutionary since it requires no recovery time.
Catheter-directed thrombolysis(CDT) is a minimally invasive endovascular treatment that is used as an adjunct to anticoagulation, CDT lowers the risk of PTS by reducing clot burden and protecting against valvular damage
IVC Filter Permanent/Temporary
The IVC filter is placed through a small incision in a vein in your groin or neck. A thin, flexible tube (catheter) is inserted into this vein. The catheter is then gently moved into your IVC. A collapsed IVC filter is sent with the catheter.
