If a doctor has mentioned the words “chronic venous insufficiency” or “CVI,” it can sound more alarming than it is. CVI is one of the most common circulation issues in adults, and the good news is that it’s well understood and treatable. Here’s what’s actually happening, why it matters, and what your options look like.
What chronic venous insufficiency is
Veins in the legs have small one-way valves inside them. Their job is to keep blood moving in one direction, up toward the heart, against gravity. When those valves weaken or get damaged, blood starts to flow backward and pool in the lower legs. That backward flow is called reflux, and the resulting condition is venous insufficiency.
When it’s been going on long enough to cause symptoms or visible changes, it gets the “chronic” label. Estimates suggest that as many as 1 in 3 adults over 50 have some degree of CVI, and it tends to run in families.
How it shows up
CVI doesn’t always look the same from one person to the next. Common symptoms include:
- Heaviness, aching, or fatigue in the legs, usually worse by the end of the day
- Visible varicose veins or worsening spider veins
- Swelling in the ankles or lower calves
- Itching or burning along certain veins
- Restless legs at night
- Skin discoloration or thickening near the ankles
- Wounds on the lower leg that take a long time to heal
Many people live with the lighter symptoms for years before seeking care, often assuming it’s just a normal part of aging or a long day on their feet.
Why it matters
Left alone, CVI tends to progress. The skin changes that look mild at first can develop into ulcers that are slow to heal. Veins that have been overworked for years are more prone to clotting. None of these outcomes are inevitable, but they’re more likely the longer the underlying reflux goes untreated.
The other reason it matters: CVI affects quality of life in ways that are easy to underestimate. People stop walking as much, skip evening activities, sleep poorly because of leg discomfort. When the underlying veins are addressed, those things often come back without much effort.
How it gets diagnosed
A duplex ultrasound is the standard test. It’s painless, takes about 30 minutes, and maps out exactly which veins are leaking and which are working normally. The result tells the specialist whether treatment is needed and which veins to focus on.
A physical exam usually comes first, but ultrasound is what confirms the diagnosis and shapes the plan.
What the treatment options actually are
Treatment has changed dramatically over the past 20 years. The old “vein stripping” surgery is rarely used today. Most current treatments are in-office, take under an hour, and don’t require general anesthesia.
The most common approaches:
- Compression therapy: medical-grade stockings worn during the day. Often the first step for milder cases.
- Endovenous ablation: a thin catheter is placed inside the bad vein and uses heat or laser to seal it shut. The body reroutes blood through healthier veins.
- Sclerotherapy: an injection that closes off smaller varicose or spider veins.
- Microphlebectomy: removal of bulging varicose veins through tiny punctures, no stitches needed.
Most patients walk out of these procedures the same day and return to normal activity within 24 to 48 hours.
Lifestyle pieces that help
Treatment works better when paired with a few habits:
- Walking daily, even short distances. The calf muscle is the body’s secondary pump for venous blood.
- Elevating the legs above heart level for 15 minutes a few times a day, when possible.
- Avoiding long periods of standing or sitting without moving.
- Maintaining a healthy weight to reduce pressure on the venous system.
These don’t reverse damaged valves, but they slow progression and ease symptoms.
When to see a specialist
If symptoms have lasted more than a few months, or if there are visible changes to the skin or veins, it’s worth getting evaluated. Most insurance plans cover CVI treatment when symptoms are documented, and an early consult often prevents the more complicated cases that show up years later.
Healthy Living Heart and Vein offers ultrasound diagnostics and the full range of in-office vein treatments at their Conroe location, with cardiology coverage in the same practice for patients managing both heart and vascular concerns.
The bottom line: CVI is common, predictable, and treatable. Catching it earlier means simpler care and a faster return to comfortable legs.
