Injection Removal Techniques
Injection removal techniques involve the use of micro-needles to inject specialized fluids into the dilated veins to cause them to collapse. Sclerotherapy utilizes a sclerosing agent to cut off blood supply to the target vessels. The solution injected into the spider veins irritates them causing them to swell or stick together.
The treatment takes 30 minutes to an hour to complete and some patients do experience a slight stinging sensation during the treatment. Immediately after the treatment, you may notice red bumps at the injection sites.Though you may not see immediate results from sclerotherapy treatments, over the weeks following the treatment, the veins will slowly fade and disappear.
Non-Surgical Removal Techniques
Endovenous Laser Treatment
Patients are prepared for endovenous laser treatment when they arrive for the procedure. The area being treated is cleaned with an antiseptic and the patient is given local anesthesia. Once the local anesthesia takes effect, the patient is positioned for the procedure.
The doctor takes a needle and inserts it into the lower end of the problematic vein. Then, a sheath is inserted into the vein. A laser fiber is then threaded through the sheath into the vein. The fiber is fed up through the vein to the topmost area of the vein that is going to be treated. Then, laser energy is fed through the fiber, heating the vein and causing it to close from top to bottom as the fiber is slowly removed. After the laser fiber and sheath is removed, the doctor places a small bandage on the treated area and provides the patient with a compression stocking to be worn for a short period of time during recovery.
Radio Frequency Occlusion
Patients arriving for radio frequency occlusion treatments are prepared for the procedure initially through a gentle cleansing of the area being targeted using an antispectic. Then, local anesthetic is applied to the area being treated.
The doctor then inserts a catheter into the problematic vein. This catheter is then used to deliver radiofrequency energy to the vein, which heats the tissues, ultimately causing it to collapse. Once the blood supply to the vein is shut off, the vein dies and slowly disappears over time.
Many patients are able to return to work immediately following a radio frequency occlusion treatment. Recovery is often quick and patients experience very little pain associated with the procedure.
Lasers and Intense Pulsed Light
Laser treatment for spider vein removal is a relatively straightforward process that does not use needles or injections. The procedure is ideal for spider veins that measure less than 3 millimeters. Laser light is directed at the patient's skin where spider veins are visible. The lasers are able to target just the veins without affecting the surrounding tissue. Laser energy causes the blood inside the spider veins to become heated, which causes it to clot. Once the blood inside the vein is clotted and the blood supply to the spider veins cut off, the vein dies.
Each laser treatment session is performed for about 15 to 20 minutes and patients sometime report that the heat from the laser creates discomfort. Topical anesthesia may be applied if the discomfort is too intense. Patients may notice that the spider veins are more visible immediately following the surgery. However, over the one to two weeks following treatment, the veins will slowly fade and disappear.
Surgical Removal Techniques
Ligation surgical procedures for spider vein removal require patients to undergo general anesthesia, but you can have it done as an outpatient procedure. The procedure is only recommended for severe cases of varicose veins. Other, less invasive procedures are more appropriate for less severe venous issues. Your ligation surgery will begin after you are anesthetized and the target area is prepared for the procedure. Your doctor will make an incision and tie off the problematic vein before pulling it out of the body. After the procedure, the target area will be bandaged. Most patients recovery fully from ligation surgery within 1 to 4 weeks.
