Venous Stent

If you come to Hamilton Vein Center for treatment of pelvic vein stenosis, you can expect to have a venogram, which may involve a possible angioplasty (balloon inflation) and stent placement depending on your provider’s assessment.

Symptoms of pelvic vein stenosis are listed below. Many of these symptoms are common with those of chronic venous insufficiency (CVI) and may include:

  • Leg swelling
  • Leg pain
  • Ulcers
  • History of deep vein thrombosis (DVT, also called a blood clot) in the iliac and/or common femoral vein
  • Varicose veins on the lower body including groin and thighs

The vast majority of vein problems in the leg are caused by the superficial veins known as the great and small saphenous veins, which are the veins that we treat using radiofrequency ablation. Once these veins are treated, the leg problems usually improve or resolve. However, if a patient has persistent, slight improvement or new symptoms after treatment, they may require further testing to determine the cause of symptoms. Occasionally, compression of the deep veins in the pelvis can cause symptoms like persistent swelling, leg pain, blood clot in the deep veins of the legs, and ulcers. When the pelvic veins are treated, the blood flow out of the legs is improved enough that the symptoms will go away. If you have not had resolution of these issues or are experiencing these issues and have not been treated for CVI, you should get an evaluation from an interventional radiologist or vein specialist. At Hamilton Vein Center, we will perform a comprehensive ultrasound of your legs and/or a pelvic venogram to determine your diagnosis.

When you come in for a venogram procedure, you can be assured that you will be well taken care of. You will be asked to change into a hospital gown and lie on an x-ray table. An IV (intravenous) line is started to give you fluids and medications. You may be given medication to help you relax. The skin at the insertion site is numbed with medication. You may be given antibiotic through the intravenous line.

A very small incision is made over the insertion site. Then, a needle with a thin guide wire is inserted through the skin into the vein. A catheter (thin, flexible tube) is placed over the guide wire into the blood vessel. Contrast medium is injected into the blood vessel. This helps the veins show clearly on x-ray images. Using these images as a guide, the provider assesses the vein for any blockage and moves the catheter to the narrowed or blocked part of the vein.

When the catheter reaches the narrowed or blocked area, a special balloon attached to the catheter is inflated (angioplasty). This widens the passage through the vein. To hold the vein open, a stent may then be inserted. To do this, a catheter with a stent attached is threaded over the guide wire. When the stent reaches the narrowed area, it is opened carefully. The stent stays in the vein. All catheters, wire, and balloons are removed.

The procedure takes about an hour. Recovery time after the procedure is approximately one to two hours. During the recovery time your blood pressure, heart rate, and insertion site will be monitored as the sedation medication wears off.

We are dedicated to our patients and the diagnosis and treatment of vein-related diseases with our multiple locations across Texas.
