Venous stent placement is the most common surgical procedure in deep venous thrombosis (DVT) management. Clinical studies show an increased efficacy of venous stenting in the long-term improvement of blood circulation in the leg. As a result, there has been a steady rise in some DVT treatments through angioplasty and stenting. Here are the basic details about the role of angioplasty and venous stenting in the definitive management of DVT.
What is Angioplasty?
Angioplasty is a surgical procedure that involves opening up narrow veins to widen the vessel diameter. A thin tube is inserted into the affected leg vein to improve blood flow. When the tube has entered the vessel, a balloon is inflated to maximize vessel patency. To prevent damage to the vessel lining, a physician who specializes in interventional procedures must perform angioplasty.
What is Venous Stenting?
Venous stenting is an interventional procedure that follows angioplasty. When you achieve increased vessel circumference post-angioplasty, a small device is needed to keep the vein open. The presence of a stent improves the long-term outcome of surgical DVT treatment. Clinical studies also show that recurrence of blockage formation in the vein is significantly decreased when a mesh-like stent is placed inside the vessel.
What Factors Can Influence Stent Performance?
Stent performance is highly dependent on several factors. After the surgery, the patients must remain compliant with prescribed medications to prevent stent failure. Most vascular specialists prescribe anticoagulants and antiplatelet drugs to inhibit clot formation inside the stent. Blood thinners also decrease the recurrence of clot formation which may eventually lodge on the newly formed stent. The location of stent placement also plays a crucial role to maintain vessel patency.
The Bottom Line
Angioplasty and venous stent placement are the definitive treatment for patients who suffer from severe symptoms of DVT. Patients who undergo lifestyle modifications with supplementary blood thinners experience significant symptomatic relief post-operatively. Thus, it is crucial to undergo immediate surgical intervention when progressive tissue death causes poor functional capacity.
