The complexity of the human vascular system, comprising arteries and veins, is often taken for granted until a problem arises. Vascular health is vital for delivering oxygenated blood to tissues (via arteries) and returning deoxygenated blood to the heart (via veins). When this system falters, conditions like chronic leg ulcers and vein disease can develop, necessitating specialist care, particularly in a medically advanced setting like Singapore.
Understanding Vein Disease and Prevention
Vein disease, or venous insufficiency, primarily occurs when the one-way valves in the leg veins are damaged, causing blood to flow backward and pool in the lower extremities. This pressure buildup leads to symptoms like swelling, visible varicose veins, and skin changes. Arterial disease, in contrast, involves blockages or narrowing of the arteries, restricting oxygen-rich blood flow, and often causing pain upon activity (claudication) and cold extremities.
Preventing vein disease is crucial. Key strategies include maintaining a healthy weight, engaging in regular exercise (like walking or swimming) to strengthen calf muscles that help pump blood, avoiding prolonged periods of standing or sitting, and elevating the legs above heart level when resting. In Singapore, vascular health tips emphasize these lifestyle changes alongside regular health checks to monitor risk factors like high blood pressure and cholesterol, which are also critical for overall cardiovascular health.
Chronic Leg Ulcers and Specialist Treatment in Singapore
A significant complication of unmanaged venous insufficiency is the development of chronic leg ulcers, specifically venous leg ulcers (VLUs), which are the most common type of leg ulcer. These are non-healing wounds that result from severe blood pooling and subsequent skin breakdown.
In Singapore, the treatment of chronic and non-healing wounds is a specialised, often multidisciplinary process. A leg ulcer specialist or wound care clinic will provide a comprehensive assessment to diagnose the underlying cause, which may involve a lower limb ultrasound to check venous flow. Treatment for VLUs generally focuses on three pillars:
1.
Wound Care: Proper cleaning, types of RFA debridement (removal of dead tissue), and advanced dressings to manage infection and promote a moist healing environment.
2.
3.
Compression Therapy: Applying bandages or specialized stockings to reduce swelling and aid blood return to the heart, which is a cornerstone of VLU management.
4.
5.
Addressing the Root Cause: This often involves minimally invasive procedures targeting the faulty veins, such as Radiofrequency Ablation (RFA) or Endovenous Laser Ablation (EVLA), to seal the damaged vein. In severe cases, surgical intervention may be necessary.
6.
Minimally invasive vein treatments like RFA typically last under an hour and provide long-lasting relief, though side effects can include temporary numbness or bruising. Another innovative approach for smaller veins is Cryo-Laser and Cryo-Sclerotherapy (CLaCS), which combines a laser and an injected solution with skin cooling. A clacs procedure recovery time session lasts about 30 minutes to an hour, and patients typically have minimal recovery time, often resuming normal activities quickly, though results may take a few weeks to fully appear.
Related Vascular and Health Concerns
Beyond leg ulcers, vascular specialists in Singapore also manage complex conditions such as venous malformations, difference between artery and vein problems which are abnormal clusters of veins. Treatment, especially in the legs, often involves embolization—a minimally invasive procedure using image guidance to intentionally block the abnormal vessels.
Additionally, patients may require information on dialysis, a procedure for kidney failure. The two main types are Haemodialysis (filtering blood through an external machine, typically 3-5 hours, 2-3 times a week) and Peritoneal Dialysis (using the abdominal lining as a filter). Potential side effects include low blood pressure (Haemodialysis) and peritonitis (infection, Peritoneal Dialysis).
For women, uterine fibroids are benign tumours that can cause symptoms like heavy bleeding or pelvic pressure. Their growth is linked to hormones. Treatment is tailored based on symptoms and fertility goals, ranging from medication to procedures like Uterine Artery Embolization (to cut off blood supply to the fibroids) or surgical removal (myomectomy or hysterectomy).
Effective management of vascular disease, including chronic leg ulcers, requires a proactive approach to prevention and timely consultation with a specialist. Singapore's healthcare landscape offers comprehensive diagnostic and therapeutic options, from lifestyle modifications and minimally invasive vein treatments to complex surgical interventions, ensuring patients receive targeted care for optimal vascular health and quality of life.
