Venography & Vein Stenting

Venography/ultrasound imaging and vein stenting is a minimally invasive technique where we inject contrast dye directly into the vein to visualize it and then, if necessary, place a stent (metal mesh tube) in the vein to help keep the vein open to allow normal passage of blood (most commonly performed on patients with severe pelvic vein compression).
Vein stenting involves placing venous stents in the veins to improve the flow of blood. These venous stents are metal mesh tubes which expand once they come in contact with narrowed or blocked vein walls. These venous stents help in keeping the veins open. The procedure is usually performed on larger, central veins found in the leg, abdomen, or chest.
What’s more, the venography and vein stenting procedure helps patients with chronic blood clots or other conditions which narrow or compress the veins and affects normal blood flow. Vein stenting can be used to treat venous conditions like chronic deep vein thrombosis, post-thrombotic syndrome, and so forth.
Who Is a Candidate for Vein Stenting?
Patients suffering from blocked veins and blood flow issues may be eligible for the procedure. During your initial consultation, Dr. Ramanath will examine your veins and possibly perform a ultrasound test. He will then decide if a venogram is appropriate. The venogram is a minimally invasive procedure that shows the anatomy of the veins.
The Vein Stenting Procedure
At times, ultrasound imaging may not be effective due to the position of the vein. In this case, Dr. Ramanath may recommend a venogram. This is an x-ray based procedure which allows the physician to see the anatomy of your veins.
During the procedure you will be given medications to make you sleepy. Next, the physician will carefully insert a catheter into a vein. Contrast dye will then be injected into the catheter. This makes it possible for the veins to be visualized.
In a situation that a blood clot is obstructing the vein, Dr. Ramanath may first perform a Thrombectomy before placing the vein stent. Here, a needle will be inserted into the vein in the affected area. Then, a balloon-tipped catheter will be carefully guided to the position. The balloon is inflated and deflated several times to open up the blocked veins.
To place a vein stent, the physician will remove the balloon and insert another catheter with a closed stent attached to it. Placing the stent into the vein pushes it against the vein walls. This will help keep it open. The physician carefully removes the catheters. Pressure is applied to the insertion point to close the wound.
The procedure is typically completed within two hours. After a few hours of bed rest the patient is discharged from the hospital.
Total recovery may take up to a couple of weeks. After the procedure, you will be asked to wear a compression stocking. You can perform light activities like walking. However, avoid any vigorous physical activities during this period.
Side Effects and Potential Risks
Like all minimally invasive procedure, you may experience side effects such as mild bruising, and discomforts.
