Vascular Procedures in Danville

Vascular procedures treat diseases affecting the vascular system, also called the circulatory system. At East Bay Cardiovascular & Thoracic Associates, our surgeons perform vascular procedures for Danville, Pleasanton, Concord, Walnut Creek, and San Ramon patients.

Vascular Procedures

What Is the Vascular System?

The vascular system is made up of veins, arteries, and lymphatic vessels. It carries blood, oxygen, nutrients, and lymphatic fluid throughout the body. When issues with circulation arise, they can result in a number of problems, from varicose veins to heart attacks and strokes. Vascular procedures are used to address or prevent these problems.

  • Dialysis Access

    Dialysis is short for hemodialysis, which is a blood treatment procedure for patients with chronic kidney failure. The kidneys filter waste from the blood, but when the kidneys fail, dialysis is necessary to take over that filtering.

    Dialysis is necessary when 85 to 90% of kidney function is lost. During dialysis, blood is removed from a vein and circulated through a filtering machine before being returned to the body.

    Vascular Access for Dialysis
    Veins tend to have weak blood flow that is not durable enough to provide the necessary output of dialysis. Because of this, a doctor will often surgically connect a vein to a nearby artery to strengthen the vein and allow for heavier circulation. The increased strength allows long-term dialysis to be possible.

    Types of Vascular Access
    The needs of dialysis patients vary, and therefore there are three main types of vascular access for treatment that may be recommended:

    • Arteriovenous Fistula
      An arteriovenous, or AV, fistula is the surgical connection of an artery to a vein. The fistula is created during a minor outpatient procedure under local anesthesia. Fistulas typically take some time to mature, but they are usually the preferred method for dialysis access due to less risk of complications over artificial grafts and catheters and higher durability.
    • Arteriovenous Grafts
      If a patient has small veins that will not properly develop into a fistula, they will typically require a synthetic tube graft to make the connection between the artery and vein. This graft can be used for needle access during hemodialysis. Unlike fistulas, a graft does not need ample time to develop and therefore is a better option when access is needed more urgently.
    • Venous Catheters for Temporary Access
      For quickly progressing kidney disease, patients may need a venous catheter for temporary but immediate access. Catheters are not ideal for permanent access.

    Complications of Vascular Access
    As with any procedure or treatment, there are risks. Most often the complications are associated with venous catheters. Risks associated with all three types of vascular access, although uncommon, may include:

    • Infection
    • Low circulation
    • Blood clots
  • Sclerotherapy

    Sclerotherapy is a minimally invasive procedure that treats varicose and spider veins, most often in the legs. The injection of a solvent into the veins causes the vessels to collapse and restore proper blood flow.

    Reasons for Spider Vein Treatment
    Those who are affected by varicose veins, either for cosmetic reasons or because of painful/dangerous symptoms due to the diseased veins, can undergo sclerotherapy. Some symptoms include:

    • Swelling and redness at the site
    • Cramping of legs
    • Scaly, discolored, and dry skin at the site
    • Discomfort after standing or sitting for long periods
    • Pain, burning or aching in feet and legs

    The Sclerotherapy Procedure
    The procedure includes the injection of saline and a sclerosant into the affected veins. These substances will cause the veins to collapse and eventually be reabsorbed into the body so that other healthier veins can take over and provide proper circulation.

    The procedure is proven to be safe and effective and can be performed as an outpatient procedure in less than an hour. There is little to no discomfort during the process, even without anesthesia. Typically, only a mild burning sensation is reported.

    Risks of Sclerotherapy
    Although sclerotherapy is a safe and successful procedure, there are certain possible risks that may include:

    • Inflammation
    • Bruising and discoloration (temporary)
    • Blood clots
    • Air bubbles in bloodstream
    • Nerve damage
    • Allergic reaction to sclerosant

    Recovery from Sclerotherapy
    Patients can return home the same day and most can return to work and regular activities the next day. Exercise and strenuous activities should be avoided for about a week or two. For about a week after the procedure, compression bandages should be worn.

    Some improvement might be seen immediately, but full results may take about a month to be apparent. It is recommended that patients maintain healthy lifestyles by controlling weight and regularly exercising to promote vascular health and preserve the effects of their sclerotherapy.

  • Endovenous Laser Therapy

    Endovenous laser therapy, or EVLT, is a minimally invasive procedure used to treat varicose veins. EVLT has both cosmetic and health benefits and is considered safe, quick, and effective. The outpatient procedure takes less than an hour and can be performed in the doctor’s office. EVLT provides instant relief of symptoms without scarring or a long recovery and is FDA-approved with a 98% success rate.

    The EVLT Procedure
    During the procedure, the physician will mark the affected veins and use an antiseptic and local anesthetic. A laser probe is then inserted into the vein and positioned properly, confirmed with imaging and ultrasound.

    The laser energy targets the damages veins and causes them to collapse so that blood can no longer flow through. Healthier vessels will take over the blood flow that the disease’s veins were previously circulating. The probe is removed and compression bandages are applied.

    The Risks of an EVLT
    Although EVLTs are considered safe, there are certain risks associated with any surgical procedure. Some risks may include:

    • Numbness
    • Vein inflammation
    • Deep vein thrombosis
    • Infection
    • Ineffectiveness of the procedure
    • A drawing sensation

    Recovery from EVLT
    Most patients experience temporary tightness in the legs and mild bruising, but these symptoms will subside within a few days. Patients can go home immediately after the procedure and can resume normal activities on the same day. Strenuous activities should be avoided for a period of time suggested by the physician.

    Results are typically visible immediately. Because of the fast recovery and pain-free results, most patients enjoy more attractive legs and are satisfied with the procedure. EVLT is becoming the new standard treatment for varicose veins.

  • Microphlebectomy

    Microphlebectomy or stab phlebectomy is a minimally invasive procedure that treats varicose veins. Microphlebectomy is performed when the veins are too large for sclerotherapy but too small for laser ablation. The procedure uses small punctures that remove damaged veins and divert blood flow to healthy ones.

    The Procedure
    The procedure will take place in your doctor’s office under local anesthetic. A microphlebectomy usually has a very short recovery time and patients can typically return to regular activities the same day but should avoid strenuous activity for a week. Patients usually are required to wear compression bandages for the week following the procedure to minimize bleeding and swelling.

    Risk of Microphlebectomy
    Although this procedure is considered safe, there are certain risks associated with any surgical procedure. There is a possibility of bruising and discomfort for a few days, and in rare instances, a skin nerve injury.

  • Deep Vein Thrombosis

    Deep vein thrombosis, or DVT, is a condition in which a blood clot, or thrombus, occurs in a vein that is deep in the body. Most commonly DVT occurs in the legs.

    Causes of DVT
    Most patients with DVT are over the age of 60, but the condition can occur at any age. Some causes that result in DVT may include:

    • Long periods of bed rest or inactivity
    • Pressure from pregnancy or obesity
    • Inherited conditions
    • Vein damage
    • Reactions to medication
    • Hormone replacement or birth control
    • Smoking
    • Certain cancer treatments

    Symptoms of DVT
    About half of all DVT cases are present without symptoms. If symptoms do occur, they may include:

    • Pain at the site
    • Swelling in the legs, ankles, and feet
    • Swelling along the vein
    • Redness or discoloration of the skin
    • Warmth to the touch

    Diagnosis of DVT
    Your physician will check your blood pressure, breathing, and heart sounds and do a thorough physical examination of the legs. Some other diagnostic tests for DVT may include:

    • Ultrasound
    • Venography
    • CT scan
    • MRI scan
    • D-dimer test
    • Blood tests

    Treatment of DVT
    Most treatments are focused on preventing the thrombus from growing in size and the development of another clot. Treatments will also focus on preventing an embolism, which occurs when a clot or the segment of plaque breaks off and travels elsewhere in the body and creates a dangerous blockage.

    This can occur in the lungs, heart, or brain, and therefore can cause life-threatening strokes or heart attacks. The best course of treatment for DVT will likely be a combination of compression and medication.

    Compression Stockings
    Special elastic stockings that put pressure on the veins will be prescribed to keep the blood from clotting and pooling. In less severe cases, these stockings may keep the condition under control on their own.

    Blood thinners are medications that cause easier circulation. Heparin (injection or intravenous tube) and warfarin (pill form) are common anticoagulants.

    Thrombin Inhibitors
    These medications interfere with the blood clotting process by inhibiting the enzyme thrombin.

    Vena Cava Filter
    This filter is placed inside the vein that carries blood from the lower half of the body back to the heart called the vena cava. The filter prevents a pulmonary embolism by catching blood clots before they can get to the lungs.

    Symptoms of DVT
    Some symptoms of an embolism may include:

    • Sudden shortness of breath
    • Sharp chest pain
    • Pain worsened by deep breathing or coughing
    • Dizziness
    • Cough with pink, foamy mucus

    Prevention of DVT
    Improvement of vascular health will lessen the risk or slow the progression of DVT. Some methods of improving vascular health are:

    • Losing weight
    • Quitting smoking
    • Managing blood pressure
    • Regular exercise
    • Not sitting or standing in one place for too long
  • Endovenous Laser Ablation

    Endovenous Radiofrequency Ablation, or RFA, is a minimally invasive treatment of varicose veins. As blood pools in the veins, the walls of the vessels become damaged and appear raised and visibly twisted. Varicose veins can be a cosmetic problem, but they can also become dangerous and painful.

    Reasons for RFA
    Varicose veins result from venous reflux or the backward flow of blood in the veins. Symptoms may include:

    • Feeling of heaviness in legs
    • Bleeding, ulceration, and discoloration along the veins
    • Pain while sitting or standing
    • Swelling and distension along the veins

    Patients will small varicose veins called spider veins may not be candidates for RFA and sclerotherapy may be a better option.

    Benefits of RFA
    Some benefits of an RFA include the following:

    • Small incisions with no scars or sutures
    • Little to no pain or discomfort
    • Short recovery time
    • Immediate relief
    • Successful removal of damages vessels

    The RFA Procedure
    The skin will be numbed with a local anesthetic and a radiofrequency catheter is inserted in the vein. Ultrasounds images confirm proper placement, and the vein is exposed to the RF energy to seal off the vein. Blood flow will be taken over by healthier veins and proper circulation will be restored.

    Risks of RFA
    While RFAs typically have a low incidence of complications and are considered safe, all surgical procedures have associated risks. These risks may include:

    • Thrombophlebitis
    • Deep vein thrombosis
    • Nerve damage
    • Skin burns
    • Bruising
    • Infection

    Recovery from RFA
    Patients can return to regular activities the very same day after their procedure but should avoid strenuous activity for a few weeks. If pain occurs, it is usually mild and only occurs for a few days.

    Compression stockings should be worn for about a week after the procedure to prevent swelling and bruising. Making healthy lifestyle changes will prevent future vascular damage and ensure the longevity of the RFA’s results.

Vascular Conditions Treated

Peripheral Artery Disease (PAD)
Peripheral Artery Disease (PAD) occurs when the arteries that supply blood to the limbs become narrowed or blocked. This can cause symptoms such as leg pain, numbness, and cramping. Left untreated, PAD can lead to severe complications, including limb loss.

Carotid Artery Disease
Carotid Artery Disease involves the narrowing or blockage of the carotid arteries, which supply blood to the brain. This condition increases the risk of stroke and requires careful management to prevent severe neurological damage.

Aortic Aneurysm
An aortic aneurysm is an abnormal bulge in the wall of the aorta, the largest artery in the body. If an aneurysm ruptures, it can cause life-threatening bleeding. Early detection and management are crucial to prevent complications.

Varicose Veins
Varicose veins are swollen, twisted veins that often appear on the legs. They can cause discomfort, pain, and cosmetic concerns. Treatment can alleviate symptoms and improve the appearance of affected veins.

Deep Vein Thrombosis (DVT)
Deep Vein Thrombosis (DVT) is a condition where a blood clot forms in a deep vein, typically in the leg. DVT can lead to serious complications, such as pulmonary embolism, if the clot travels to the lungs. Prompt treatment is essential.

Lymphedema is the swelling of limbs due to the accumulation of lymphatic fluid. It can result from damage to the lymphatic system, often due to surgery or radiation therapy. Managing lymphedema involves reducing swelling and preventing infections.

Vascular Treatments Offered

Angioplasty and Stenting
Angioplasty is a procedure that uses a balloon to open narrowed or blocked arteries. Stenting involves placing a small mesh tube in the artery to keep it open. These procedures restore blood flow and relieve symptoms associated with artery blockages.

Atherectomy is a minimally invasive procedure that removes plaque from the inside of an artery. This treatment improves blood flow and is often used in conjunction with angioplasty and stenting.

Bypass Surgery
Bypass surgery creates a new pathway for blood to flow around a blocked artery. This is done by grafting a vessel from another part of the body. Bypass surgery is commonly used for severe cases of PAD or coronary artery disease.

Venous Ablation
Venous ablation is a minimally invasive procedure that treats varicose veins. It involves using heat or chemicals to close off the affected veins, which are then reabsorbed by the body. This procedure alleviates symptoms and improves vein appearance.
