The Vascular Associates of San Diego Vein Clinic has a state of the art, accredited, vascular lab with two duplex scanners and certified vascular technicians for convenient and efficient diagnoses of your vascular symptoms. All diagnostic and therapeutic procedures are office based in friendly and pleasant surroundings.
Sclerotherapy is a nonsurgical treatment for varicose veins. It consists of using microneedles to inject the veins with a salt solution. Over several months, the treated vein goes through a process called sclerosis, where the walls collapse and are eventually reabsorbed. At the completion of the process, the vein is no longer a blood carrying vessel and cannot be seen or felt. Other normal veins take over the function of these sclerosed veins.
Foam sclerotherapy is sometimes used for more extensive varicose veins. It is similar to sclerotherapy, however, in this procedure air is mixed with a salt solution and ultrasound guidance is used to direct the foam into multiple interconnected varicose veins.
THE VNUS CLOSURE® PROCEDURE
The Closure procedure is performed on an outpatient basis. Using ultrasound, the doctor will position the Closure catheter into the diseased vein through a small opening in the skin. The tiny catheter powered by radio-frequency (RF) energy delivers heat to the vein wall. As the thermal energy is delivered, the vein wall shrinks and the vein is sealed closed. Once the diseased vein is closed, blood is re-routed to other healthy veins.
Newer technology allows closing the abnormal veins using nonthermal catheter techniques that do not require compression with less pain experienced during the procedure. These new, state of the art procedures, are now being offered at Vascular Associates of San Diego.

FREQUENTLY ASKED QUESTIONS
WHAT ARE VARICOSE VEINS?
Varicose veins are enlarged tortuous veins that typically affect the legs. They are veins that become enlarged and twisted with pooling of blood when they fail to properly circulate the blood back toward the heart. The smaller spider veins are located in the skin, while varicose veins are larger bulging veins that are beneath the skin layer. Varicose veins are a very common problem. They occur in approximately one out of every five women and one out of every twenty men. More than 36 million people in the United States are afflicted with this condition.
These abnormal veins are frequently associated with symptoms. They can cause itching, burning, and aching pain. Many varicose vein sufferers complain of heavy or tired legs, especially at the end of the day. Others have no symptoms, but are so distressed by their unsightly appearance that they never wear shorts or swimming suits that would expose their varicose veins. In severe cases, varicose veins can rupture or form open sores called venous ulcers.
HOW DO VARICOSE VEINS OCCUR?
Veins normally have a series of valves that help the blood flow upwards from the legs and back to the heart. If these valves are absent or incompetent, venous blood tends to pool in the legs. Over a period of time the affected veins elongate and dilate. The ultimate result is the condition we describe as varicose veins. It is easy to understand that symptoms are aggravated by prolonged standing or sitting. The combined effects of gravity and faulty valves cause increasing pressure in the leg veins. This condition is commonly referred to as venous insufficiency, and is the primary cause of varicose veins.
WHAT ARE THE CAUSES AND COMPLICATIONS OF VARICOSE VEINS?
Heredity is the primary cause; however, certain hormones (estrogen & progesterone) are definitely a factor. It accounts for the strong predominance of women with this condition. Pregnancy can aggravate the problem because of hormonal changes, increased blood volume, and compression of pelvic veins. Often varicosities which occur during pregnancy will disappear after delivery. More often than not, however, the veins persist and enlarge over time.
There are several other causes of venous insufficiency and the resulting varicose veins. A history of phlebitis or thrombophlebitis, which is an inflammation and/or thrombosis of the veins, eventually leads to venous insufficiency. Local traumatic injury, causing fragile surface veins to break, can also cause varicosities to develop. Additionally, obesity and certain occupations requiring long periods of sitting or standing can be aggravating factors.
There are several complications of untreated varicose veins. Varicose veins may become inflamed resulting in a painful condition called superficial thrombophlebitis. Another common complication is profuse bleeding, which may occur either spontaneously or after mild trauma to the varicosity. A late complication is brownish pigmentation of the skin in the lower calf, sometimes leading to skin breakdown and ulcer formation. These venous stasis ulcers can be very difficult to heal and occasionally require skin grafting.
WHAT TREATMENT CHOICES ARE AVAILABLE FOR VARICOSE VEINS?
Most of the symptoms of varicose veins can be relieved with graduated compression support stockings. If properly fitted, these stockings compress the varicose veins and reduce the effects of blood pooling in the lower leg; therefore limiting the occurrence of long-term complications.
Radiofrequency or laser ablation of the saphenous vein has replaced vein stripping as the treatment of choice for venous insufficiency with symptomatic varicosities. This outpatient procedure can be done without a surgical incision. Utilizing a small needle puncture in the skin a catheter is inserted into the saphenous vein at the level of the knee. The catheter employs heat to ablate the vein from the groin to the knee region. The procedure is performed in our office-based operating room and can be done with local anesthetic. There is minimal post-procedure pain or bruising and you can resume normal activity following the procedure. Saphenous vein ablation is usually performed in conjunction with follow-up sclerotherapy for the treatment of residual varicose veins.
WHAT IS SCLEROTHERAPY?
Sclerotherapy is a popular minimally invasive way to treat varicose veins. The procedure consists of using micro-needles to inject the affected veins with a salt solution. The vein becomes inflamed after being exposed to this solution. Over a period of several weeks to several months the vein goes through a process called sclerosis, where the walls collapse and are eventually reabsorbed. At the completion of the process the vein is no longer a blood carrying vessel and cannot be seen or felt. Other normal veins will take over the function of these sclerosed veins.
Following injections, compressive dressings are applied for large varicose veins and are usually worn for one week. When spider veins are injected, smaller dressings are applied and can be removed the following day. Patients are encouraged to walk at least 15 minutes immediately following the procedure and 15 minutes daily while the compressive dressings are worn. Normal activity can be resumed immediately after the treatment session.
The number of sessions after the initial consultation varies from one to three depending upon the number and severity of the varicose veins. Each treatment session takes approximately one-half hour. It is performed as an outpatient procedure in the Vein Clinic and requires no anesthesia.
ARE THERE ANY SIDE EFFECTS OF SCLEROTHERAPY?
There are few side effects related to sclerotherapy. Following removal of the dressing, some bruising at the injection sites may be noted. It is also not unusual to have small harmless blood clots trapped within the injected veins. The body reabsorbs this clot as the vein is reabsorbed. In larger varicose veins this trapped blood can be felt as a hard lump beneath the skin. These lumps eventually soften and disappear over several months. Brownish pigment in the skin is occasionally present at the site of an injected varicosity. This, too, eventually fades and disappears, but in the case of darker areas of pigmentation, this process can take as much as a year. Unlike surgery, sclerotherapy does not leave scars and can be used effectively on all size veins, from tiny spider veins to very large, bulging varicose veins in the calf and thigh.
A combination of the VNUS Closure Procedure and Schlerotherapy is usually required for the best results.
