Central venous stenosis treatment and venoplasty
Central venous stenosis treatment and venoplasty are endovascular procedures to treat a narrowing of large central veins, with the main treatment being percutaneous transluminal angioplasty (PTA), or venoplasty, which uses a balloon to open the vein. Venoplasty may be combined with stent placement to hold the vein open, especially for stubborn or recurrent stenoses. These minimally invasive options are the preferred treatment for central venous stenosis, which often affects patients who require hemodialysis.
- Common symptoms of Central Venous stenosis:
- - Arm, neck, or face swelling: This is often the most common and noticeable symptom.
- - Prolonged bleeding: Bleeding from the access puncture site may last longer than usual after needles are removed.
- - Poor or insufficient dialysis: Patients may experience a decrease in dialysis efficiency or be unable to achieve the target blood flow rate.
- - Increased venous pressure: This can be measured during dialysis and indicates a blockage in the venous system.
- - Difficulty with cannulation: The access site may become harder to use because of the poor blood flow or other complications.
- - Skin changes: The skin over the affected arm or chest may become discolored (red, purple, or blue) or develop an ulcer.
- - Aneurysmal dilatation: The veins of the access can become significantly enlarged.
- - Advanced symptoms: In severe cases, this can lead to more widespread swelling or even respiratory issues and breathlessness.
- Central venous stenosis treatment
- • Endovascular approach: The preferred method for treating central venous stenosis (CVS) is a minimally invasive endovascular procedure.
- • Commonly affected veins: Stenosis can occur in the subclavian, brachiocephalic, or superior vena cava.
- • Endovascular treatment options:
- - Covered stents: Newer options like covered stents are also being explored.
- - Stent placement: A stent, or metal scaffold, is often placed after the venoplasty, particularly if the vein has a tendency to recoil or if there is significant residual stenosis after the balloon is deflated.
- - Percutaneous transluminal angioplasty (PTA): Also known as venoplasty, this is the primary treatment, involving the use of a balloon to open the narrowed vein.
