Vein Services Provided

Dr. Klein has performed over 1000 procedures at the Vein Center of Arizona. He believes that customizing the treatment plan to the needs of each individual has been the key to excellent results.

Vein Imaging - We perform ultrasound studies of the legs in order to evaluate for the presence of abnormalities such as blood clots. We pay particular attention to the direction of flow of blood in the veins and the function of the small valves within the veins.

Compression Therapy - Often patients with edema or venous reflux can benefit from compression stockings to alleviate pain, swelling, aching, fatigue. A good physical exam and noninvasive imaging study will help make this determination.

VNUS Radiofrequency Ablation - Superficial vein reflux can cause symptoms such as leg pain, fatigue, bulging varicose veins, leg aching, itching, and swelling. In advanced cases, this condition can lead to dangerous ulceration of the skin or bleeding varicose veins. VNUS Radiofrequency Ablation is a minimally invasive technique performed in the office under ultrasound guidance that uses radiofrequency energy to treat dysfunctional veins and redirect flow toward healthy veins.

Here is a video of a ClosureFast™ endovenous radiofrequency ablation procedure.

Ambulatory Phlebectomy - This is a minimally invasive technique that can be used to remove small to medium sized varicose veins through a series of tiny incisions through which the vein is removed.

Sclerotherapy - Often spider veins are found in conjunction with other vein conditions. These small superficial branching veins often arise due to problems with the microscopic valves within these veins. Risk factors for spider veins include prolonged standing, multiple pregnancies, and strong family history of spider or varicose veins. Sclerotherapy is a technique in which a tiny needle is used to deliver a medication into the vein. This causes the inner layer of the vein to scar, displacing the blood, which results in the fading or disappearance of the spider vein. This procedure can be done for spider veins causing itching, burning and discomfort, or for cosmetic reasons.

Dr. Klein would be happy to discuss the indications, risks, and benefits of all procedures with prospective patients.

Here is a video of a sclerotherapy procedure done by Dr. Klein. 

Experience the VenaSeal™ Closure System

The VenaSeal™ closure system is the only non-tumescent, non-thermal, non-sclerosant procedure that uses a proprietary medical adhesive delivered endovenously to close the vein. This unique approach eliminates the risk of nerve injury when treating the small saphenous vein, which is a risk sometimes associated with certain thermal-based procedures.1,2  Clinical studies have demonstrated that the procedure is safe and effective.1-4  The procedure is administered without the use of tumescent anesthesia, avoiding patient discomfort associated with multiple needle sticks.


Before the VenaSeal™ Closure Procedure:

You will have an ultrasound imaging exam of the leg that is to be treated.  This exam is important for assessing the diseased superficial vein and planning the procedure.

During the Procedure:

Your doctor can discuss the procedure with you.  A brief summary of what to expect is below:
•You may feel some minor pain or stinging with a needle stick to numb the site where the doctor will access your vein.
•Once the area is numb, your doctor will insert the catheter (i.e., a small hollow tube) into your leg. You may feel some pressure from the placement of the catheter.
•The catheter will be placed in specific areas along the diseased vein to deliver small amounts of the medical adhesive. You may feel some mild sensation of pulling or tugging. Ultrasound will be used during the procedure to guide and position the catheter.
•After treatment, the catheter is removed and a bandage placed over the puncture site.

After the Procedure:

You will be taken to the recovery area to rest.  Your doctor will discuss with you what observations will be performed following treatment.

Potential Risks:

The VenaSeal procedure is minimally invasive and catheter-based. As such, it may involve the following risks. Your doctor can help you understand these risks.


  • Allergic reaction to the VenaSeal adhesive
  • Arteriovenous fistula (i.e., an abnormal connection between an artery and a vein)
  • Bleeding from the access site
  • Deep vein thrombosis (i.e., blood clot in the deep vein system)
  • Edema (i.e., swelling) in the treated leg
  • Hematoma (i.e., the collection of blood outside of a vessel)
  • Hyperpigmentation (i.e., darkening of the skin)
  • Infection at the access site
  • Neurological deficits including stroke and death
  • Non-specific mild inflammation of the cutaneous and subcutaneous tissue
  • Pain
  • Paresthesia (i.e., a feeling of tingling, pricking, numbness or burning)
  • Phlebitis (i.e., inflammation of a vein)
  • Pulmonary embolism (i.e., blockage of an artery in the lungs)
  • Urticaria (i.e., hives) or ulceration may occur at the site of injection
  • Vascular rupture and perforatio
  • Visible scarring
