If your legs often feel heavy, swollen, or achy, venous reflux may be the underlying cause. Many patients in Austin and Bee Cave live with these symptoms for years before learning what is happening inside their veins. At South Austin Vein Center, Founder and Medical Director Dr. Michael M. Di Iorio and NP Candice Di Iorio bring more than 20 years of experience treating vein disease.
Our focus is not only on treatment but also on helping patients understand their condition so they can make informed decisions about their care. Here’s what you need to know about venous reflux and the early warning signs of chronic venous insufficiency (CVI).
What Is Venous Reflux?
Healthy leg veins contain small one-way valves that keep blood moving upward toward the heart. These valves open to allow blood to flow up and close to prevent it from flowing backward. When the valves weaken or fail, blood begins to leak backward and pool in the lower legs. This backward flow is called venous reflux.
Instead of circulating efficiently, blood builds pressure inside the vein. Over time, that pressure stretches the vein walls, leading to visible varicose veins and uncomfortable symptoms.
Common signs of venous reflux include:
• Leg heaviness or fatigue
• Swelling in the lower legs or ankles
• Throbbing or aching discomfort
• Bulging varicose veins
• Symptoms that worsen after prolonged standing
How Venous Reflux Progresses to Chronic Venous Insufficiency
When venous reflux continues without treatment, the constant pooling of blood increases pressure in the lower legs. This ongoing pressure damages surrounding tissues and affects circulation more broadly. Over time, this condition can develop into CVI.
Chronic venous insufficiency occurs when the veins can no longer return blood to the heart effectively and consistently. Blood remains trapped in the legs, and symptoms worsen.
CVI may lead to:
• Persistent swelling that does not improve overnight
• Skin discoloration around the ankles
• Thickened or hardened skin
• Itching or irritation
• Venous ulcers that are slow to heal
At this stage, the condition affects daily comfort and mobility. Early diagnosis and intervention can prevent progression.
Diagnosis and Minimally Invasive Treatment
A detailed ultrasound evaluation allows specialists to identify refluxing veins and determine the severity of the condition. South Austin Vein Center specializes in advanced, minimally invasive treatments for venous reflux disease and varicose veins. Techniques such as radiofrequency ablation, VenaSeal, and sclerotherapy close diseased veins and reroute blood to healthy vessels.
Their approach centers on individualized treatment plans and patient education in a comfortable, welcoming setting.
If you experience leg swelling, visible varicose veins, or ongoing discomfort, call South Austin Vein Center at 512-614-1025 or book a consultation to learn how we can help.
