Vein Management
Vein Management
Vein conditions can range from varicose veins which are swollen, visible veins in the legs to more serious conditions like deep vein thrombosis (DVT), where a blood clot forms in a deeper vein. While varicose veins are often seen as a cosmetic concern, they can also cause:
- Aching or heaviness
- Leg swelling
- Skin changes
- Discomfort affecting daily life
DVT is more serious, as the clot can:
- Block blood flow
- Travel to the lungs (pulmonary embolism)
At CVSKL, we provide comprehensive vein care, ensuring accurate diagnosis and the right treatment ranging from lifestyle advice to advanced minimally invasive procedures.
What is Deep Vein Thrombosis (DVT)?
Deep vein thrombosis (DVT) is a potentially life-threatening condition in which a blood clot forms in a deep vein, most commonly in the lower extremities, such as the legs. These clots, also known as thrombi, can obstruct normal blood flow and cause swelling, pain, and damage to the surrounding tissues. While some cases of DVT resolve without complication, others may lead to severe and life-threatening consequences if not identified and treated early.
- Prolonged immobility: Long flights, car rides, or bed rest can slow blood flow in the legs.
- Surgery and hospitalisation: Especially involving the pelvis, legs, or hips.
- Obesity and sedentary lifestyle: Increased pressure in leg veins can slow blood flow.
- Smoking: Damages blood vessels and increases clotting risk.
- Hormonal therapy: Including birth control pills or hormone replacement therapy.
- Pregnancy: Hormonal changes and increased pressure on pelvic veins.
- Family history of clotting disorders: Genetic factors can predispose individuals to abnormal clotting.
How we treat DVT
Treatment aims to restore blood flow, prevent clot progression and reduce long-term complications.
Blood Thinning (Anticoagulation)
- Prevents the clot from growing
- Reduces risk of new cloth
Medication is used to break down the clot and restore blood flow.
How it works:
- Given through a drip or directly via a catheter
- Acts to dissolve the clot from within
A minimally invasive procedure to physically remove the clot.
How it works:
- A catheter is inserted through a blood vessel
- Special devices remove or suction the clot
- Blood flow is restored immediately
In selected cases:
- A stent may be placed to keep the vein open
- Often combined with blood-thinning therapy
This helps:
- Improve circulation
- Reduce symptoms
- Prevent long-term complications such as post-thrombotic syndrome
What are varicose veins?
Varicose veins are enlarged, twisted veins visible under the skin, usually in the legs. They occur when vein valves weaken, causing blood to flow backward and pool.
Common Causes & Risk Factors
- Age
- Family history
- Pregnancy
- Obesity
- Prolonged standing
Symptoms to Watch For:
- Bulging, twisted veins are visible on the legs
- Leg pain, cramping, or heaviness
- Swelling, especially after prolonged standing
- Skin pigmentation, eczema or ulcers in severe cases
Treatment for varicose veins
Treatment relies on the severity of varicose veins, symptom strength, and patient choice. Advances in medical technology have made minimally invasive procedures the preferred choice, giving effective results with less pain and downtime.
A. Minimally Invasive Procedures
These treatments close off or remove affected veins without the need for large incisions:
Endovenous Laser Therapy (EVLT): A thin laser fibre is inserted into the vein to deliver precise energy that closes the vein wall, rerouting blood to healthier veins.
Radiofrequency Ablation (RFA): Similar to EVLA, but uses radiofrequency energy to heat and stop the vein. It is known for comfort and quick recovery, successfully lowering symptoms such as pain and swelling.
Glue Ablation: is a special glue used to treat varicose veins. A new method of vein closure that does not require anaesthesia, does not involve cutting or burning, and allows for quick recovery.
What is glue closure?
Cyanoacrylate is a special medical glue that hardens quickly when it touches blood, sealing the vein shut. This causes the vein to close and eventually turn into scar tissue. Studies show it works very well for treating varicose veins, with over 90% of treated veins staying closed after a year—similar to heat-based treatments. It’s also considered safe, with very few complications reported.
Sclerotherapy: A medical foam is injected into the vein to cause it to collapse, redirecting blood flow to healthier veins. It’s a simple outpatient procedure, though several treatment sessions may be needed.
Ambulatory Phlebectomy: Involves removing superficial varicose veins through small punctures in the skin. It offers immediate cosmetic results with minimal scarring.
B. Surgical Treatments
Surgery is generally reserved for large or complicated varicose veins:
Vein Stripping and Ligation: Involves tying off and removing affected veins through small incisions. While effective, surgery requires a longer recovery and may leave scars.
Microphlebectomy: Similar to ambulatory phlebectomy but targets smaller veins.
Modern surgical techniques use smaller incisions and local or regional anaesthesia to reduce discomfort and recovery time.
What are Arteriovenous Malformations (AVMs)
AVMs are abnormal connections between arteries and veins, bypassing normal blood flow pathways. This can lead to:
- High-pressure blood flow
- Strain on vessels and surrounding tissues
How Are AVMs Treated?
Treatment depends on size, location, and symptoms, and may include:
- Endovascular embolisation
(blocking abnormal vessels using coils or glue) - Surgical removal
(for accessible AVMs) - Stereotactic radiosurgery
(targeted radiation for deeper or smaller AVMs)
When is Treatment Needed?
Treatment may be recommended if the AVM:
- Causes pain or bleeding
- Affects function or organs
- Has a risk of rupture
- Has previously bled
FAQ - Varicose Veins
Varicose veins are visible, palpable, dilated and tortuous veins caused by weakened valves that allow blood to pool. They most commonly appear on the legs due to gravity and valve failure.
While treatments can effectively close or remove affected veins, new varicose veins may develop over time. Ongoing prevention and monitoring are important.
Minimally invasive procedures usually allow return to normal activities within a few days. Surgical options may require weeks for full recovery.
Modern treatments are minimally invasive, performed under local anaesthesia, and have low complication rates when done by experienced professionals at accredited centres.
Yes, regular exercise, weight management, avoiding prolonged immobility, leg elevation, and compression stockings help reduce risk and symptom progression.
Once venous ulcers develop, they must be managed professionally to ensure proper healing. With timely and appropriate care, ulcers can heal within a shorter period, and the risk of recurrence can be significantly reduced.
FQA - Deep Vein Thrombosis (DVT)
DVT often starts with swelling, pain, and tenderness in one leg, particularly in the calf or thigh. You may also notice skin discolouration, warmth, or a feeling of heaviness. These symptoms can be mild or go unnoticed, so it’s important to seek medical attention at CVSKL if you experience any of them, especially if you are at higher risk.
CVSKL uses advanced diagnostic tools such as Duplex Ultrasound, D-Dimer blood tests, and CT Pulmonary Angiogram (for suspected lung clots) to accurately detect the presence, location, and severity of DVT or pulmonary embolism. These non-invasive procedures are quick, precise, and performed by experienced specialists.
CVSKL provides a full range of DVT treatments tailored to each patient’s condition. This includes anticoagulant medication, thrombolytic (clot-busting) therapy, IVC filter placement, compression therapy, and surgical thrombectomy when necessary. All treatments aim to stop the clot, reduce symptoms, and prevent life-threatening complications like pulmonary embolism.
Yes, DVT can often be prevented through lifestyle changes and medical guidance. CVSKL offers preventive care options that include risk assessments, use of compression stockings, smoking cessation, and long-term health monitoring. Patients recovering from surgery or with a family history of clotting disorders are especially encouraged to consult CVSKL for preventive strategies

Deep vein thrombosis is the formation of a blood clot in a deep vein, usually in the legs, caused by slow blood flow, vessel injury, or increased clotting tendency.
If a clot breaks loose and travels to the lungs, it causes a pulmonary embolism, which can be fatal without urgent treatment.
Treatment typically lasts at least for three months but may be extended depending on the cause and risk of recurrence.
Light movement and leg exercises are encouraged to improve circulation, but vigorous activity should be discussed with your healthcare provider.
Yes. Preventive measures include staying active during long travel, managing risk factors, wearing compression stockings when advised, and following medical recommendations.
