Veins as Vital Pathways in the Circulatory System

The circulatory system is responsible for the transportation of blood throughout the body. Veins act as vessels for blood flow and they serve various purposes:

  1. Veins act as the return path for blood that has delivered oxygen and nutrients to body tissues. After this exchange occurs in the capillaries, veins carry the oxygen-depleted blood back to the heart and lungs for reoxygenation.
  2. The contraction of surrounding muscles during movement helps push blood through the veins, especially in the limbs. This movement helps prevent blood from pooling in the lower extremities.
  3. Veins contain one-way valves that ensure blood flows in the correct direction—toward the heart. This prevents backflow and aids in the efficient return of blood to the heart.

When veins experience dysfunction, as seen in conditions like varicose veins, their importance becomes even more apparent. Varicose veins are enlarged, twisted veins that often result from damaged or weakened vein walls and valves. These conditions can disrupt blood flow, leading to symptoms such as pain, swelling, and discomfort.

Managing varicose veins is crucial not only for symptom relief but also for maintaining the overall health of the circulatory system. Varicose veins can lead to complications like blood clots or skin ulcers. Therefore, addressing varicose veins is not just a matter of cosmetic concern but also one of circulatory health.

Identifying Common Symptoms & Risk Factors of Varicose Veins

While varicose veins may not always be painful, they are identifiable through certain visual characteristics, such as the presence of dark purple or blue veins that appear twisted and swollen, resembling cords on the legs. However, when varicose veins do cause discomfort, individuals may experience sensations of heaviness or aches in the legs, along with symptoms like burning, throbbing, muscle cramps, and swelling in the lower leg area. These tend to intensify after extended periods of sitting or standing. Itching in the vicinity of the affected veins and alterations in skin pigmentation near varicose veins are also potential signs of this condition.

Understanding and recognizing varicose vein risk factors is vital for both early intervention and preventive measures:

  1. Age – Increased age contributes to wear and tear of vein valves, leading to blood backflow and pooling.
  2. Gender – Females are more vulnerable due to hormonal fluctuations during pregnancy, pre-menstruation, or menopause, which relax vein walls.
  3. Pregnancy – The condition is more likely during pregnancy as the body copes with elevated blood volume to support the growing fetus, causing vein enlargement.
  4. Family History – A family history of varicose veins raises the risk of developing the condition.
  5. Obesity – Excess weight places additional pressure on veins, heightening the risk.
  6. Prolonged Standing – Occupations involving extended periods of standing can strain blood flow, increasing susceptibility to varicose veins.

How Vascular Surgeons Diagnose Varicose Veins

Step 1: Medical Interview

  • The vascular surgeon asks about any symptoms you might have, like leg aches, discomfort, swelling, or itching around the veins.
  • This assessment helps the vascular surgeon get an initial idea of the problem.

Step 2: Clinical Assessment

  • A vascular surgeon examines your legs, and they look for visible signs of varicose veins, such as dark purple or blue twisted veins.
  • They assess the size of these veins and check for skin discoloration and texture changes.

Step 3: Ultrasound Scan

  • To get a more detailed image of your legs, you may be asked to undergo an ultrasound.
  • A technician or sonographer applies a special gel to your legs. An ultrasound transducer is used to emit and receive sound waves. Sound waves bounce off the blood vessels in your legs, creating real-time images on a screen.
  • These images confirm the presence of varicose veins. They also reveal critical information about the root causes, such as faulty vein valves or blockages.

Step 4: Comprehensive Diagnosis

  • Combining the clinical examination and ultrasound scans ensures a thorough and accurate diagnosis. This comprehensive assessment enables vascular surgeons to develop a treatment plan tailored to your specific condition and needs.

While varicose veins are generally a common and manageable vascular condition, it’s important to be aware of potential complications that can arise. While these occurrences are infrequent, understanding and recognizing these complications is crucial for prompt medical intervention and effective management:

  1. Painful ulcers can develop on the skin near varicose veins. Typically, a discolored spot on the skin appears before an ulcer forms. If you suspect you have a leg ulcer, it’s crucial to seek immediate medical attention.
  2. In some cases, deep veins within the legs may become enlarged, causing leg pain, and swelling. Persistent leg pain or swelling should prompt you to seek medical attention, as it could indicate the presence of a blood clot.
  3. Occasionally, veins located close to the skin’s surface may burst. While this usually results in minor bleeding, it still necessitates medical attention to address the issue effectively.

Exploring Varicose Vein Treatment Options in Singapore

  1. Compression stockings improve blood flow within the leg veins, providing relief from associated symptoms, and impeding the progression of the condition. This can effectively boost blood circulation and alleviate discomfort. It’s important to explore alternative treatment options, especially in cases of severe varicose veins.
  2. Traditional open surgery for varicose veins is commonly referred to as “high-tie ligation and vein stripping.” This procedure necessitates general anesthesia and typically involves an overnight hospital stay. While it has been a conventional approach, open surgery is often associated with several drawbacks. Patients undergoing this method tend to experience higher levels of postoperative pain, and the recovery process can be slower compared to more modern and minimally invasive alternatives.
  3. Minimally invasive procedures offer similar benefits to traditional surgery but come with reduced pain and faster recovery times. These procedures involve small incisions rather than large openings. Advanced technology allows for tiny punctures through which probes are inserted to seal the affected vein. Typically performed as day surgery, this approach allows for a swift return to daily activities without the need for a prolonged hospital stay. It is conducted under local anesthesia or light sedation, utilizing heat, mechanical, or chemical methods to seal the vein efficiently.
  • Radio Frequency Ablation (RFA) – Radiofrequency energy is used to heat up and damage the vein wall. A fast and safe outpatient procedure, it takes about 35-40 minutes to perform.
  • Venseal™/VenaBlock Glue Closure – A small amount of specially formulated medical adhesive is used to seal the varicose vein permanently. Through the closure of these veins, blood is rerouted to healthy veins located nearby, providing relief. This procedure provides a comfortable experience and typically is completed within 15-20 minutes.
  • Clarivein™ Mechanochemical Ablation – This procedure combines the mechanical destruction of the veins and the injection of sclerosant (a chemical used in sclerotherapy that seals off veins). A special catheter is inserted that has a wire rotating at high speed, damaging the innermost layer of the vein (or the venous intima). At the same time, there is the controlled injection of sclerosant which seals off the vein. This is a painless technique which requires a lot less local anaesthetic injection. Additionally, there is no risk of heat-induced to surrounding nerves due to the mechanochemical ablation technique.
  • Cryo-Laser and Cryo-Sclerotherapy (CLaCs) – Suitable for spider veins, this procedure combines transdermal laser and injection sclerotherapy using a chemical sclerosant, all under skin cool (-20C). It leaves minimal scarring and pigmentation post-surgery. This procedure makes use of the Harmony XL PRO. Using its light, laser, and AFT (Advanced Fluorescence Technology), affected blood vessels beneath the skin are targeted.

Selecting the Right Varicose Vein Treatment in Singapore

Choosing the right varicose vein treatment is a decision influenced by several factors, mainly the patient’s individual condition, lifestyle, and the evaluation of an experienced vascular surgeon. Varicose veins are a complex vascular issue, and the most suitable treatment can vary greatly among patients.

Firstly, factors like the severity of varicose veins, and location, and any associated symptoms are key considerations. Mild cases may find relief with non-surgical options like compression stockings, which improve blood circulation and alleviate discomfort. However, as varicose veins progress or become more symptomatic, advanced treatments may become necessary.

Aside from this, the vascular surgeon examines the patient’s lifestyle. Their level of physical activity, occupation, and daily routine can impact treatment preferences. Active individuals or those with physically demanding jobs may prefer minimally invasive procedures for quicker recovery and minimal disruption. Conversely, those leading more sedentary lives may have different treatment preferences.

Preparing for Varicose Vein Treatment

These are three key tips to help you get ready for your varicose vein treatment:

  1. Before undergoing varicose vein treatment, it’s essential to schedule a consultation with a qualified vascular surgeon. The specialist will evaluate your condition, conduct necessary tests like ultrasound scans, and discuss your medical history.
  2. Take the time to educate yourself about the varicose vein treatment recommended by your vascular specialist. Understand the procedure’s details, potential risks, and expected outcomes. Ask questions during your consultation to ensure you have a clear grasp of what to expect before, during, and after the treatment.
  3. Planning for post-treatment recovery is crucial. Depending on the procedure, you may need to arrange for someone to drive you home afterward, especially if anesthesia is involved. Stock up on any recommended compression garments or medications, and ensure your home is set up for a comfortable recovery period. Follow your vascular surgeon’s post-treatment instructions diligently to optimize healing and achieve the best results.
