What are incompetent perforating veins?
Perforating veins are the small connecting veins that link the surface (superficial) veins of your legs to the deep veins. When their one-way valves fail, blood leaks backward toward the skin instead of returning to the heart — a problem known as incompetent perforating veins that can drive varicose veins, swelling, and skin changes.
Quick answer
Incompetent perforating veins are connecting veins whose valves no longer close properly, allowing blood to flow the wrong way from the deep system into the superficial veins. This added pressure can cause bulging veins, aching, swelling, and skin changes, and it is often part of underlying venous insufficiency that can be evaluated and treated at Charming Skin & Vein Clinics.
What causes incompetent perforating veins?
Perforating veins become incompetent when the valves inside them weaken and can no longer stop backward flow. This is usually part of a wider pattern of venous reflux and is more likely with the following factors.
- Genetics — a family history of varicose veins or venous insufficiency raises your risk.
- Aging — vein walls and valves naturally lose elasticity and strength over time.
- Chronic venous insufficiency — existing reflux in nearby veins places extra load on the perforators.
- Prolonged standing or sitting — long periods without movement increase pressure in the leg veins.
- Obesity — excess weight adds pressure that can strain perforating vein valves.
- Pregnancy — hormonal changes and increased pelvic pressure can contribute to valve failure.
Symptoms of incompetent perforating veins
Symptoms often reflect the extra pressure and pooling that backward flow creates near the skin. Common signs include:
- Bulging or varicose veins that appear over or near a leaking perforator.
- Swelling in the legs and ankles, particularly later in the day.
- Leg pain, aching, or heaviness after long periods of standing or sitting.
- Skin discoloration or darkening around the ankle from long-standing pooling.
- Restless or tired legs, sometimes worse at night.
Left untreated, incompetent perforating veins can contribute to more advanced problems such as chronic venous insufficiency and venous leg ulcers.
Why treat incompetent perforating veins?
Because perforating veins feed the surface veins, ongoing reflux through them can keep varicose veins and swelling from improving and may lead to skin damage over time. Addressing the underlying source of backward flow relieves symptoms and helps prevent progression toward more serious venous conditions.
How we evaluate and treat it
Incompetent perforating veins are usually part of a broader picture of venous reflux, so we start by understanding what is happening beneath the skin before discussing treatment. Dr. Abboud brings more than 20 years of experience caring for veins, and care begins with a clear diagnosis and a plan matched to your symptoms.
- Ultrasound vein diagnosis to map blood flow and pinpoint which perforating veins and valves are not working as they should
- Varicose vein treatment for enlarged, bulging veins that often develop when perforators leak
- Endovenous laser treatment (EVLA) to close a refluxing underlying vein and redirect flow to healthier veins
- Compression therapy to support the leg veins and ease symptoms day to day

Common questions
When should I see a vein doctor about incompetent perforating veins?
It is worth scheduling an evaluation if you notice bulging or twisting veins, aching or heaviness in the legs, swelling that builds through the day, or skin changes near the ankles. These can be signs that perforating veins and valves are no longer supporting healthy blood flow, and an ultrasound can show what is happening.
Is treatment covered by insurance?
Most PPO plans and Medicare cover treatment for symptomatic veins. Purely cosmetic vein work is self-pay. We are glad to review your symptoms and help you understand your coverage before any treatment.
What can I expect at a free vein screening?
Your screening is a relaxed, informational visit. We listen to your symptoms, look at your legs, and talk through whether an ultrasound and further evaluation make sense. There is no pressure — the goal is to help you understand your veins and your options.
Medically informed care
Vein care at Charming Skin & Vein Clinics is led by Dr. Abboud, who brings more than 20 years of medical experience — a graduate of the University of Damascus with residency training at Cook County Hospital and John H. Stroger Jr. Hospital in Chicago. This page is for general education, reviewed for accuracy, and is not a substitute for an in-person evaluation.
Because incompetent perforating veins often appear alongside surface vessels and underlying venous reflux, we may recommend varicose vein treatment or an ultrasound vein diagnosis to map the source before planning care.
