Endovenous laser treatment is required to eliminate defective superficial veins (Varicose Veins) forcing blood to return to the heart through the normal deep venous system.
What Are Varicose Veins?
Veins and arteries, while both part of the circulatory system, function quite differently from each other. "Poor circulation" is a nonspecific term which often refers to arterial blockages. Arteries bring oxygen-rich blood from the heart to the extremities and can be thought of like a tube or hose. Veins, unlike arteries, have one-way valves and channel oxygen-depleted blood back toward the heart. If the valves of the veins don't function well, blood doesn't flow efficiently. When the valves fail or leak, blood flows back through the vein causing the blood to pool, a condition termed reflux or venous insufficiency.

Normal Vein   Abnormal Vein (Incompetent Valves)
Valve failure in the major leg vein (the great saphenous vein) is the most common cause of vein reflux and varicose veins in other parts of the leg. And typically, veins visible in the lower thigh, knee and calf are often due to vein reflux in higher areas of this major vein. Venous insufficiency dilates the vein and puts additional pressure on the healthy valves. The result is varicose veins that appear as twisted, enlarged veins that lie close to the surface of the skin. It is very important to understand that the varicose veins you see on the surface of the skin are in fact branches of the incompetent major superficial leg veins (ie. Great or Small Saphenous Vein).
Small or Short Saphenous Vein
Great or Long Saphenous Vein
   
Examples of Varicose Veins:



What Are The Symptoms of Varicose Veins?
  • Aching or burning in the legs
  • Pain in the legs
  • Swelling of the legs or ankles
  • Leg cramps or sores
  • Itching of the skin around a vein
  • Eczema of the skin typically in the calf region
  • Open wounds such as skin ulcers around the ankle
Symptoms secondary to varicose veins are often made worse by prolonged standing, include feelings of fatigue, heaviness, aching, burning, throbbing, itching, cramping, and restlessness of the legs.
What Is The Incidence And Causs For Varicose Veins?
Nearly 70% of all women and 30% of men will develop some type of venous disorder due to insufficient blood circulation.  Although the exact cause is unknown, there are many that contribute to the weakening of the vein walls including:
  • Heredity
  • Pregnancy
  • Hormonal factors
  • Being overweight
  • Standing or sitting for long periods of time
  • Advancing age
  • Injury
Heredity is the number one contributing factor causing varicose and spider veins. Women are more likely to suffer from abnormal leg veins. Hormonal factors including puberty, pregnancy, menopause, the use of birth control pills, estrogen, and progesterone affect the disease. It is very common for pregnant women to develop varicose veins during the first trimester. Pregnancy causes increases in hormone levels and blood volume which in turn cause veins to enlarge. In addition, the enlarged uterus causes increased pressure on the veins. Varicose veins due to pregnancy often improve within 3 months after delivery. However, with successive pregnancies, abnormal veins are more likely to remain. Other predisposing factors include aging, standing occupations, obesity and leg injury.
How Do We Diagnose Varicose Vains And Venous Insufficiency
At The Vein Institute of Toronto we have developed our own method of evaluating patients through our extensive research and experience in treating patients with a wide variety of varicose and spider veins. The Vein Institute of Toronto patient evaluation process is as follows:
  • Upon coming to our office you will begin by filling our own developed confidential patient venous questionnaire
  • You will then undergo a personal consultation with our Medical Director Dr. Sanjoy Kundu
  • He will review your venous questionnaire to focus on the most important findings and symptoms to you
  • You will then undergo a focussed venous physical examination to map out all your varicose and spider veins
  • Dr. Kundu will then personally perform a venous ultrasound examining your superficial and deep venous system
  • A personalized treatment plan will then be presented to you with the different treatment options
Our patient evaluation process has been taught by Dr. Kundu to numerous physicians in North America and Europe.
What Is EVLT?
At The Vein Institute of Toronto EVLT is a quick, minimally invasive, outpatient, laser procedure performed utilizing imaging guidance. After applying tumescent anesthesia to the vein, the interventional radiologist inserts a thin catheter, about the size of a strand of spaghetti, into the vein under ultrasound guidance and guides it up the greater saphenous vein in the thigh or the lesser saphenous vein in the calf. Then pulses of laser light are delivered inside the vein. This heats the vein and seals the vein closed. There is no post operative scarring, as only a tiny laser probe and a slim plastic sheath enters the vein via a tiny skin nick.

The key benefits of EVLT:

  • Immediate relief from symptoms
  • No scars
  • Only a local anesthetic is needed
  • Can be performed in the doctor's office (no hospitalization needed)
  • Treatment in less than an hour
  • Normal activities can be resumed immediately - with little or no pain

Endovenous Laser Ablation of Great Saphenous Vein
At The Vein Institute of Toronto we have developed our own method for performing EVLT through our research, patient feedback and extensive procedure experience. We perform one of the largest volumes of EVLT in Canada and North America and are a training and luminary site for the EVLT procedure for other physicians.
The Vein Institute of Toronto Method:
  1. Each patient undergoes a personal physician consultation as outlined above.
  2. On the day of the procedure, the patient undergoes application of local anesthetic spray and cream to the area to be treated to minimize discomfort.
  3. The patient undergoes a mapping ultrasound by Dr. Kundu before the procedure to confirm the patient’s anatomy and area to be treated to decrease procedure time and note any changes from the time of the patient’s consultation.
  4. Utilizing Dr. Kundu’s unique micropuncture technique, the vein to be treated is accessed and a plastic tube enclosing the laser probe is inserted. We then select a the laser appropriate for each individual patient.
  5. Dr. Kundu ensures correct positioning of the laser probe using the ultrasound as a guide to ensure complete and accurate treatment.
  6. We then apply tumescent anesthesia around the vein to ensure effective action of the laser and minimize patient discomfort.
  7. After the procedure is completed one our knowledgeable staff will help the patient apply the medical compression stockings. Dr. Kundu will then personally review the post-procedure instructions with you.
  8. The patient is then entered into our post-procedure protocol (see below) to ensure the vein treated by the laser has been effectively closed and that the branch varicose veins are appropriately treated by either foam sclerotherapy or microphlebectomy.
  9. Each patient is able to walk out after the procedure and return to work within two days depending on the type of occupation.
A. Utilization of Specific Lasers Based on the Patient’s Individual Needs:
At the Vein Institute of Toronto we utilize two different types of laser based on the patient’s venous anatomy and characteristics of the vein to be treated. We are one of the few clinics to utilize two different lasers to maximize patient results.
Diomed Delta Laser
Dornier D940 Laser
One of the features of the Diomed Delta laser, is a very bright aiming light beam which is required when the vein to be treated is quite deep underneath the skin. One of the key features of the Dornier D940 laser is the patented LPS system to ensure continous laser action during the treatment with a built in feedback loop.

B. Use of Micropuncture Technique for Vein Access with No Surgical Cutdowns:
At The Vein Institute of Toronto we utilize a unique micropuncture technique to insert the laser fiber, which minimizes patient discomfort, and has led to a 98% technical success rate in performing the procedure.
C. Use of a Mechanical Pump to Apply Tumescent Anesthesia
Closure of the saphenous vein is accomplished in our office using only tumescent anesthesia . Tumescent anesthesia is one of the major advances in vein surgery. It was developed by Klein. It has been used most commonly by dermatologists and plastic surgeons for liposuction. Recently it has been applied to other procedures including, particularly, vein surgery. Tumescent means swelling or distention. When we administer tumescent anesthesia, the tissues are flooded with dilute liquid anesthetic and become distended giving an appearance resembling the outside of an orange. The French term for this is peau d'orange. The unique feature of tumescent anesthesia is that it involves the use of a very low concentration of local anesthetic. The large volume of fluid causes vessels to be compressed resulting in minimal bleeding. The anesthesia achieved by this technique is excellent and has a prolonged duration allowing you to get home long before the anesthesia wears off. Additionally, the post-operative discomfort seems remarkably diminished. There are no incisions in the groin. We utilize a Klein pump during administration of the tumescent anesthesia to minimize patient discomfort.

Before EVLT
 
After EVLT
  1. All patients at The Vein Institute of Toronto™ will undergo a comprehensive venous consultation including a focussed venous history and physical exam, followed by a duplex ultrasound to document venous (great or small saphenous vein) reflux, rule out deep venous thrombosis and map out the superficial venous system.
  2. If the patient decides to proceed with the procedure, they should follow the pre-procedure medication protocol comprised of Arnica™ and Toradol™. A EVLA kit including Arnica™ tablets/gel, gel pack and prescription for other optional medications may be obtained from The Vein Institute of Toronto™.
  3. The EVLA procedure is performed with the patient in a supine position for the great saphenous vein, and in a prone position for the small saphenous vein. The procedure takes approximately 45 minutes to perform for one leg and is performed under local anesthesia. At The Vein Institute of Toronto™ we utilize a unique micropuncture technique to perform the EVLA procedure which has produced a 98% technical success rate.
  4. After the procedure a dressing is applied to the venous puncture site, and a physician assistant will assist the patient to put on the compression stockings. Patients should wear the Class II (30-40 mm Hg ) compression stockings continuously for the first 72 hours, and then from first thing in the morning to before bed time at night for another 10 days.
  5. All patients will be followed up at six and twelve weeks with a venous ultrasound to confirm the great or small saphenous vein is occluded along with foam sclerotherapy injections for any residual varicose veins. Patients should bring their stockings for all follow-up appointments.
  6. At your 6 and 12 week follow-up appointments, you will be given the option of entering into our Leg Wellness Program to prevent future leg veins.
Endovenous Laser Ablation (EVLA) Pre-Procedure Instructions
  1. Take 5 pellets of Arnica™, 3 times per day, for 5 days prior to the procedure. Place pellets under the tongue and allow them to dissolve in your mouth. Arnica™ is a homeopathic medicine which has been proven to reduce pain, bruising and swelling after the procedure. Also take one 10 mg tablet of Toradol™ 3 hours prior to your procedure to minimize discomfort during the procedure (as per your prescription).
  2. Your normal medications may be taken on the morning of your procedure along with a light breakfast.
  3. You should refrain from using any type of blood thinner for 10 days prior to your procedure, please check with the physician who prescribed your medication to verify that you may discontinue this medication for this period of time.
  4. Please inform the doctor involved with the procedure of any health problems, allergies and/or medication you are currently taking.
  5. Wear loose, comfortable clothing that will be easy to put on after the procedure. Please bring a warm pair of socks with you to keep your feet warm prior to the procedure. Please remove your socks, trousers and shorts prior to surgery leaving your undergarments on.
  6. It is recommended to have two pairs of compression stockings for after the procedure and alternate the two pairs of stockings daily to prevent tears, loss of elasticity and permit washing. We have a compression stocking service onsite to ensure you are measured and fitted with the correct type of stockings. Accurately fitted stockings are essential to ensure success of the procedure.
  7. Please read the enclosed post procedure instructions prior to your procedure. Follow-up appointments are required at 6 and 12 weeks post-procedure. Please bring your stockings to your follow-up appointments. All sclerotherapy injections for varicose veins are included as part of the procedure and will be performed at the follow-up appointments.
Endovenous Laser Ablation (EVLA) Post-Procedure Instructions
  1. Keep support hose on for the first 72 hours continuously.   After that wear the stockings from the first thing in the morning (ideally, take a quick 5 min shower and then put them on before doing the rest of your morning ritual), until bedtime at night for ten days.
  2. You can resume day to day activities today (excluding exercise).  You can resume exercising in two weeks (no weights for 3 weeks after the procedure). Walking or light treadmill can be performed from the day after the procedure. You can shower tomorrow morning but no hot baths, hot tub or sauna for 2 weeks.
  3. If bleeding occurs from the puncture site, apply pressure for five minutes. Remove the gauze on your leg the day following the procedure.
  4. Please continue to take 5 pellets of Arnica™, 3 times per day for 11 days after the procedure to reduce pain, swelling and bruising. Allow the pellets to dissolve in your mouth.
  5. Bruising, local swelling, some tenderness and pain are normal along the inner thigh or behind the calf after treatment, but please feel free to call the office if you have any questions.  Bruising may occur the same or following day. In most cases it will be gone after 2 weeks but could remain longer. You may develop “lumpy” areas in your groin which are tender. These are areas of normal healing. Applying a gel pack (part of EVLA kit) three times daily helps reduce the bruising. Apply Arnica Gel™ twice per day (in the morning and before going to bed) for two weeks after the procedure. Apply Pro-Derm™ Hydrogel to the treated area once a day (mid-day). Hydrogel™ and Arnica Gel™ are available in our office.  Redness and swelling around the point of entry along with tenderness may also remain longer than 2 weeks.
  6. To Prevent Pain & Bruising:
    1. Elevate your leg and please apply gel pack three times daily to the bruised, painful area.
    2. Please purchase generic Ibuprofen tablets (not Advil™) and take 600 mg three times daily orally for five days after the procedure date. If you have an allergy to Ibuprofen, please call our office. Ibuprofen may be purchased at any pharmacy.
    3. If you have severe pain, unresponsive to the above measures: Please take one to two Percocet tablets every six hours (as per your prescription). Do not Percocet within 8 hours of the procedure.

What is the Efficacy of Endovenous Laser Ablation of the Great or Small Saphenous Vein?
The success rate ranges for vein ablation ranges from 93-95 percent with a less than 5 % recurrence rate. Click on reference below.
Alternative Treatment Options:
Surgical Treatment – Vein ligation and stripping is performed under general anesthesia, regional or local anesthesia.
During this procedure, the physician will make an incision at the groin to allow the greater saphenous vein to be tied off and cut.
The vein is then pulled out of the leg through an incision at the knee.
Due to the surgical nature of this procedure, down time can vary from two to three weeks, and is more painful than other non-invasive alternatives.
In addition, there are high rates of recurrence with the surgical procedures.
One study found a 29 percent recurrence rate after ligation and stripping of the greater saphenous vein, and a rate of 71 percent after high ligation.
These recurrence rates are similar to those reported in other studies
