Chronic Venous Insufficiency (CVI)
Chronic venous insufficiency (CVI) is a circulatory disorder in which the veins—typically in the legs—are unable to efficiently return blood to the heart. This leads to blood pooling in the lower extremities, causing symptoms such as swelling, heaviness, aching, skin discoloration, varicose veins, and, in advanced cases, painful ulcers.
Causes
CVI is primarily caused by damaged or weakened valves in the leg veins, which are supposed to prevent blood from flowing backward. When these valves fail, blood begins to collect in the lower legs. Risk factors include:
- Varicose veins
- Deep vein thrombosis (DVT) or blood clots
- Prolonged standing or sitting
- Obesity, which increases venous pressure
- Pregnancy, due to increased blood volume and hormonal changes
- Age-related weakening of vein walls and valves
- Lack of physical activity, which impairs venous return
Over time, poor circulation can lead to skin changes, pain, and open sores that resist healing.
Commonly Affected
CVI most commonly affects:
- Adults over age 50
- Women, particularly those with multiple pregnancies
- Individuals who stand or sit for long periods, such as nurses, cashiers, or office workers
- People with a family history of venous disease
- Patients with a history of DVT, leg trauma, or vascular surgeries
Early signs include leg heaviness, ankle swelling, visible varicose veins, and skin darkening near the ankles. Without treatment, CVI may progress to venous ulcers or cellulitis.
Treatments Available
AllSpine Pain and Wellness offers advanced, minimally invasive solutions designed to restore healthy blood flow and reduce symptoms without the need for surgery. Our treatment options include:
- Endovenous Radiofrequency Ablation (EVRFA): A catheter-based procedure that uses heat energy to close off malfunctioning veins, redirecting blood to healthier pathways.
- Sclerotherapy: A safe, in-office injection procedure that treats varicose and spider veins by collapsing them from the inside.
- Compression Therapy: Medical-grade compression stockings promote circulation and help reduce swelling and discomfort.
- Lifestyle Modifications: Guidance on weight loss, leg elevation, exercise, and movement to reduce venous pressure and support long-term results.
Each treatment plan is customized based on severity, symptoms, and your personal goals for recovery and mobility.
Frequently Asked Questions (FAQs)
What’s the difference between varicose veins and chronic venous insufficiency?
Varicose veins are often a visible sign of CVI, but CVI involves deeper circulation issues and can exist even when surface veins appear normal.
Is chronic venous insufficiency reversible?
While the underlying vein damage cannot be undone, symptoms can be effectively managed and progression slowed or halted with proper treatment and lifestyle care.
How do I know if I need EVRFA or just compression therapy?
A vein ultrasound is often used to assess the severity of valve failure. EVRFA is recommended when conservative measures aren’t enough or symptoms are advanced.
Is vein ablation painful or does it require downtime?
No, EVRFA is minimally invasive, performed under local anesthesia, and allows most patients to walk out of the clinic and resume normal activity the same day.
What happens if CVI is left untreated?
Untreated CVI can lead to skin breakdown, ulcers, recurring infections (like cellulitis), and persistent swelling. Early intervention is key to preventing complications.
