Venous care · Los Angeles
Chronic venous insufficiency treatment starts by finding the reflux.
Leg swelling, heaviness, aching, itching, or skin changes can happen when vein valves allow blood to fall backward and pool. EVSLA uses a symptom review and venous duplex ultrasound to locate reflux or obstruction, then explains which conservative or minimally invasive options fit the pattern.
- Duplex-first diagnosis
- Minimally invasive options
- Outpatient care when appropriate
A pattern worth checking
Do your legs feel heavier by evening?
- Swelling builds after standing or sitting
- Aching, itching, or tightness eases with elevation
- Brown, red, firm, or fragile ankle skin appears
Healthy valves keep blood moving upward.
When valves leak, pressure can build from the ankle up.
What is chronic venous insufficiency?
Chronic venous insufficiency (CVI) is a long-term problem in which leg veins do not move blood back toward the heart efficiently. Weak or damaged valves can allow backward flow—called venous reflux—while a prior clot or pelvic-vein narrowing can obstruct the return pathway. The resulting pressure may cause swelling, heaviness, varicose veins, skin discoloration, inflammation, or a venous ulcer.
Symptoms alone do not show which veins are involved. A venous duplex ultrasound can map flow direction, identify reflux, look for clot, and help separate superficial-valve failure from deeper disease before a treatment is selected.

Chronic venous insufficiency symptoms
What venous pressure can feel like
Venous symptoms often build during the day or after long periods upright. The same complaints can also come from lymphatic, heart, kidney, nerve, joint, medication, or arterial problems, so the pattern needs evaluation.
Symptoms in one leg only, or one leg noticeably worse, can be a useful clue. So can pain that returns at a similar walking distance and improves with rest.
Visual signs
What venous insufficiency can look like
Photograph changes in the same lighting and bring the timeline to an appointment. Appearance is useful context, but it cannot identify the affected vein by itself.
Often noticed first
Rope-like surface veins
Enlarged superficial veins can signal reflux, with or without discomfort.
Brown ankle discoloration
Long-standing venous pressure can leave hemosiderin pigment in the skin.
Red, itchy, scaly skin
Venous eczema can resemble a rash and needs the correct diagnosis.
Firm or tightened tissue
Inflammation and scarring may make the lower leg feel hard or tender.
Open sore near the ankle
A venous ulcer often needs compression, wound care, and treatment of the underlying vein problem.
None of these confirm PAD on their own. Together, and especially on one side, they justify a focused vascular evaluation.
Clinical progression
Four checkpoints in the CEAP clinical scale
Clinicians use the CEAP system to describe visible disease from C0 through C6. These four checkpoints show why a leaking vein is not defined only by how large it looks.
C2 · Varicose veins
Visible surface veins
Bulging veins may ache, burn, itch, or feel heavy—or cause little discomfort.
C3 · Edema
Persistent leg swelling
Fluid collects around the ankle or lower leg, often worsening as the day goes on.
C4 · Skin changes
Inflamed or hardened skin
Brown staining, eczema, tissue firmness, or white scar-like areas can appear.
C5–C6 · Ulcer
Healed or active wound
A sore near the ankle may recur unless wound pressure and venous disease are addressed.
Visible disease and symptoms
Skin damage and ulcer risk
CEAP describes what is present; it does not replace duplex mapping, determine urgency by itself, or guarantee that every person moves through each class.
American Venous ForumDo not assume every swollen leg is CVI
Know the signs that need urgent care
Chronic venous insufficiency usually develops gradually. A sudden change can signal a blood clot, infection, acute circulation problem, or another condition that needs faster evaluation.
Call 911 for sudden shortness of breath, chest pain—especially with breathing—coughing blood, fainting, or severe weakness. Those can be signs of pulmonary embolism.

Why pressure builds
Venous insufficiency can come from more than one pathway
The treatment changes depending on whether the main problem is valve reflux, damage after a clot, outflow obstruction, calf-pump weakness, or a nonvenous cause of swelling.
Pathway 1
Superficial venous reflux
Valves in the great or small saphenous system do not close effectively, allowing blood to move backward when upright.
- Varicose tributaries
- Heaviness and aching
- Swelling or skin symptoms
- Mapped with duplex ultrasound
Pathway 2
Deep-vein damage or obstruction
A prior DVT can scar valves. Pelvic or iliac narrowing can also restrict blood leaving the leg and may cause asymmetric swelling.
- Post-thrombotic syndrome
- May-Thurner pattern
- Collateral veins
- Different imaging and treatment path
Contributors
Pressure, movement, and inherited risk
Family history, pregnancy, age, extra body weight, limited calf movement, and prolonged standing or sitting can increase risk or worsen symptoms.
- Family history
- Pregnancy history
- Long hours upright or seated
- Reduced ankle or calf mobility
Diagnosis before treatment
A duplex study should answer where and why
The visit begins with the symptom pattern, skin and vein exam, prior-clot history, medications, and other causes of swelling. Duplex ultrasound then evaluates the deep and superficial systems and maps flow while the care team interprets the result in context.
If symptoms suggest pelvic outflow obstruction or the duplex does not explain the leg, additional venous imaging may be considered. When compression is being prescribed and arterial disease is possible, arterial circulation should also be assessed.
- Compare one leg or both and when swelling builds
- Review prior DVT, pregnancy, medicines, and mobility
- Map superficial and deep veins before treatment
What a venous evaluation checks
History
Timing and triggers
One leg or both, morning or evening, standing, walking, elevation, pregnancy, and prior DVT.
Exam
Skin, swelling, veins, and pulses
The distribution helps separate venous, lymphatic, arterial, and systemic patterns.
Duplex
Reflux, clot, and flow direction
The study identifies involved segments and checks the deep-vein pathway.
Plan
Treat the proven source
Observation, compression, ablation, sclerotherapy, wound care, or deeper imaging is matched to the anatomy.
Chronic venous insufficiency treatment
Relieve pressure at the right level
Treatment is selected after the source is mapped. A cosmetic-looking surface vein can reflect deeper reflux, while swelling without reflux may require a different specialty or workup.
Step 1 · Support flow
Movement, elevation, skin care, and compression
Calf and ankle movement helps the muscle pump. Elevation and clinician-selected compression may reduce swelling; skin protection matters when dermatitis or wounds are present.
- Regular walking and ankle motion
- Avoid long motionless periods
- Elevate when advised
- Use prescribed compression correctly
Step 2 · Close refluxing veins
Endovenous ablation or adhesive closure
When a superficial truncal vein has clinically meaningful reflux, thermal or nonthermal closure can redirect blood through working veins.
- Radiofrequency ablation
- Endovenous laser ablation
- VenaSeal adhesive closure
- Ultrasound-guided planning
Step 3 · Treat branches or deeper disease
Sclerotherapy, wound care, or outflow treatment
Residual varicose branches may need sclerotherapy or phlebectomy. Ulcers require coordinated wound care. Iliac obstruction is evaluated on a separate pathway.
- Ultrasound-guided sclerotherapy
- Venous-ulcer compression and wound care
- Pelvic-vein imaging when indicated
- Iliac-vein stenting for selected obstruction
Procedures we may discuss
Four minimally invasive ways to address venous reflux
The ultrasound map, vein size and course, symptoms, skin changes, prior treatment, medication history, and patient preferences determine which option belongs in the conversation.
- Duplex-guided selection
- Small-access techniques
- Local anesthesia when appropriate
- Outpatient workflow
- Walking encouraged after many procedures
- Follow-up based on the treatment
Radiofrequency ablation
A catheter delivers controlled heat inside a refluxing saphenous vein so it seals and blood reroutes through working veins.
Endovenous laser ablation
Laser energy closes a selected refluxing truncal vein through a small catheter placed with ultrasound guidance.
VenaSeal closure
A medical adhesive closes a selected superficial vein without thermal energy; candidacy depends on anatomy and history.
Sclerotherapy
A solution or foam is injected into selected varicose tributaries or smaller veins so they close over time.
Who should be evaluated
When symptoms deserve a vein-focused workup
An evaluation is reasonable when symptoms persist, interfere with daily life, or are accompanied by visible or skin changes.
Bring these patterns to the visit…
- Swelling, heaviness, aching, or itching that builds during the day
- Bulging veins with discomfort, inflammation, or bleeding
- Brown, red, scaly, firm, or fragile skin near the ankle
- A current or previously healed lower-leg ulcer
- One-sided swelling or pelvic symptoms that suggest outflow obstruction
- Persistent symptoms despite movement, elevation, or prescribed compression
What happens
From a “heavy leg” to an anatomic answer
Bring prior ultrasound reports, clot history, compression garments, medication list, wound photographs, and a description of when symptoms improve or worsen.
- Screen urgent symptoms Sudden unilateral swelling, infection, arterial warning signs, and chest symptoms are triaged first.
- Map the symptom pattern The team compares timing, laterality, visible veins, swelling, skin, prior DVT, pregnancy, and mobility.
- Perform a focused exam Veins, edema, skin, ulcers, pulses, and signs of lymphatic or systemic disease are reviewed.
- Complete venous duplex Superficial and deep segments are assessed for reflux, obstruction, and clot.
- Match anatomy to goals Observation, compression, ablation, sclerotherapy, wound care, or deeper imaging is discussed.
- Set expectations The plan covers recovery, compression, follow-up, recurrence, and which symptoms should prompt a call.

Questions patients ask
Venous insufficiency, answered plainly
What is the difference between venous insufficiency and varicose veins?
Chronic venous insufficiency describes impaired return of blood from the legs, often because valves leak or outflow is obstructed. Varicose veins are enlarged surface veins and one visible form of chronic venous disease.
You can have reflux without large visible veins, and visible veins do not show whether the deep system is normal. Duplex ultrasound helps define the anatomy.
What are the early signs of venous insufficiency?
Early signs can include ankle swelling, heaviness, aching, itching, night cramps, or fatigue that builds after standing or sitting. Spider or varicose veins may also appear.
Those symptoms are not unique to venous disease. Persistent or one-sided changes deserve an evaluation rather than self-diagnosis from appearance alone.
What do the stages of chronic venous insufficiency mean?
The CEAP clinical classes range from no visible signs through spider veins, varicose veins, swelling, skin changes, and healed or active venous ulcers. Clinicians also document cause, anatomy, and whether reflux or obstruction is present.
The class helps communicate severity but does not determine treatment by itself. Symptoms, duplex findings, wound status, and patient goals also matter.
Can chronic venous insufficiency be reversed?
Damaged vein valves do not usually repair themselves. Movement, elevation, weight management, skin care, and prescribed compression can reduce symptoms and pressure. A procedure can close a proven refluxing superficial vein or treat selected obstruction.
Venous disease is chronic, so treatment aims to improve symptoms and complications rather than promise that every future vein problem is permanently eliminated.
What is the best treatment for venous insufficiency?
The best treatment depends on the source. Conservative care may be enough for mild symptoms. Confirmed symptomatic superficial reflux may be treated with endovenous ablation, adhesive closure, or sclerotherapy. Ulcers and deep obstruction need different plans.
A duplex map should come before choosing a procedure. The most advertised treatment is not automatically the correct one.
Do compression stockings treat venous insufficiency?
Compression can reduce venous pressure, swelling, and discomfort and is especially important in many ulcer-care plans. The correct strength, fit, and wearing schedule should be individualized.
Compression manages pressure but does not repair a leaking valve. People with possible arterial disease, a cold painful foot, severe neuropathy, or certain heart conditions should seek guidance before using strong compression.
Does vein ablation help circulation?
When a superficial vein has significant reflux, closing it can reduce backward flow and redirect blood through functioning veins. The deep venous system carries most of the return flow.
Improvement is most likely when symptoms match the duplex finding. Ablation may not help swelling caused mainly by lymphedema, medication, heart or kidney disease, or untreated deep obstruction.
Is venous insufficiency the same as peripheral arterial disease?
No. Venous insufficiency is a return-flow problem in veins and often causes swelling, heaviness, varicose veins, or ankle skin changes. Peripheral arterial disease reduces blood delivery through arteries and can cause exertional pain, a cold foot, weak pulses, or wounds.
Some people have both. That distinction matters before compression or a vein procedure is recommended.
Can a previous DVT cause chronic venous insufficiency?
Yes. A deep-vein clot can damage valves or leave scar-related obstruction, producing post-thrombotic syndrome with swelling, heaviness, skin changes, or ulceration.
That pattern is different from isolated superficial reflux. Bring prior clot imaging and anticoagulation history so the deep system can be evaluated.
When is leg swelling an emergency?
Seek prompt medical care for sudden one-sided swelling, pain, warmth, or redness because a DVT is possible. Call 911 for shortness of breath, chest pain with breathing, coughing blood, fainting, or severe weakness because those can signal pulmonary embolism.
A suddenly cold, pale, numb, weak, or very painful foot can be an arterial emergency and also requires immediate care.
