Latest Advancements in Minimally Invasive Vascular Vein Surgery

In Singapore, advancements in minimally invasive vascular vein surgery have redefined how venous conditions are treated, making care more effective, safer, and less disruptive to daily life. With conditions like varicose veins affecting a significant portion of the population, these innovations are both timely and necessary.

Why Addressing Vascular Issues is Crucial

Venous conditions are more than just a cosmetic issue; they can lead to chronic pain, swelling, ulcers, or even life-threatening complications such as deep vein thrombosis (DVT). In Singapore, varicose veins affect approximately 25% of adults, with women being more prone (35%) compared to men (20%). Moreover, a sedentary lifestyle, prolonged standing, and ageing increase the likelihood of developing such conditions.

Given this prevalence, the introduction of cutting-edge minimally invasive techniques in vascular vein surgery offers much-needed relief to individuals who previously relied on invasive surgeries or endured discomfort due to delayed treatment.

Breakthrough Techniques in Minimally Invasive Vascular Surgery

Advances in vascular surgery have led to highly effective, patient-friendly treatments. These techniques are redefining recovery and success rates:

1. Radiofrequency Ablation (RFA)

RFA is the gold standard method which uses radiofrequency energy to heat and close off affected veins.

• • How it Works: A catheter is inserted under ultrasound guidance to deliver radiofrequency energy, sealing the vein from the inside.
  • Advantages:
    • Short procedure time (30–45 minutes)
    • Minimal discomfort compared to traditional open surgery.
    • High success rate of over 92%
    • Effective for treating chronic venous insufficiency
    • Patients can walk after surgery.

• Disadvantages:

• • Need for multiple thigh pricks for injection of tumescent anaesthesia around the vein.
  • Need for compression stockings post-procedure to optimise closure rates.
  • Not suitable to treat below-the-knee saphenous reflux.
• Applications:
  • Suitable for large, bulging varicose veins often seen in advanced cases where cost is an issue.

2. Endovenous Laser Treatment (EVLT)

EVLT is a procedure where laser energy is delivered inside the vein, causing it to collapse and seal.

• • How it Works: A thin laser fibre is inserted into the vein under ultrasound guidance. The laser heats the vein walls, leading to closure.
  • Advantages:
    • High success rate of over 95%.
    • Patients can walk out after the surgery.

• Disadvantages:
• • Need for multiple thigh pricks for injection of tumescent anaesthesia around the vein.
  • Need for compression stockings post-procedure to optimise closure rates.
  • Not suitable to treat below-the-knee saphenous reflux.
  • Slightly more painful than RFA
  • Slightly higher complication rate than RFA
• Applications: Suitable for large, bulging varicose veins often seen in advanced cases where cost is an issue.

3. ClariVein®

First introduced in Singapore in 2012, ClariVein® combines mechanical agitation and chemical treatment for varicose veins.

• How it Works: A catheter mechanically rotates inside the vein, delivering a sclerosant solution to seal it.
• Advantages:
  • No heat, reducing the need for tumescent anaesthesia
  • Minimal bruising and faster recovery
• Applications: Ideal for patients seeking a gentler alternative to EVLT or RFA, but with a higher recurrence rate.

4. VenaSeal

The VenaSeal system uses a medical adhesive to close varicose veins without the need for heat or multiple thigh pricks.

• How it Works: A glue-like substance is injected into the vein, causing it to close instantly.
• Advantages:
  • No need for compression stockings post-treatment if 
  • One of the most comfortable options for patients
  • Latest method with the highest long term closure long term rate.

Why Minimally Invasive Surgery Matters

These innovative techniques are transforming the landscape of vascular vein surgery:

• Faster recovery: Most patients resume normal activities the same day or within 48 hours.
• Minimised risks: Small incisions reduce the likelihood of infections and scarring.
• Improved outcomes: Advanced technologies ensure higher success rates, with over 90% of patients seeing long-term improvement.
• Patient comfort: Procedures are often painless and do not require general anaesthesia.

The Future of Vascular Surgery in Singapore

The healthcare landscape in Singapore is continuously evolving, with state-of-the-art technologies becoming more accessible. The demand for skilled specialists in vascular vein surgery is increasing as awareness grows about the importance of addressing venous conditions early.

Government initiatives promoting better cardiovascular health and public awareness campaigns about varicose veins have further driven patients to seek treatments. Clinics offering minimally invasive vascular surgery are meeting this need with advanced care that prioritises both effectiveness and convenience.
