The Dangers of Varicose Veins Left Untreated
Varicose veins are not merely a cosmetic concern. Left untreated, they progress through several stages, each more dangerous than the last — up to and including life-threatening complications. I will explain exactly what happens inside the veins when we postpone a visit to the doctor.
Patients come to my practice at M-Clinic in Tashkent who have spent years watching their veins enlarge and thinking: «Well, it doesn't hurt — so I'll leave it alone.» They then arrive already dealing with complications that could have been entirely avoided. That is precisely why I decided to write this article — not to frighten anyone, but to explain: varicose veins follow a logical progression, and the earlier we intervene, the simpler and faster the treatment.
Why Varicose Veins «Stay Silent» for Years — and Why That Is Dangerous
Chronic venous insufficiency develops slowly. In the early stages a person notices only leg fatigue by evening, mild swelling, and occasional night cramps. Most people attribute this to tiredness or uncomfortable shoes. Meanwhile, blood flow inside the veins is already compromised: the valves fail to close properly, blood stagnates, and pressure inside the vessels rises.
This stagnation is the starting point for all the complications I will describe below.
Thrombophlebitis: When a Varicose Vein Becomes Inflamed
One of the most frequent complications is acute thrombophlebitis of the superficial veins. Stagnant blood in a dilated vein creates ideal conditions for clot formation. The inflamed vein becomes firm and tender, and the overlying skin turns red and warm.
It might seem that a superficial vein is not so serious. But there is a significant trap here: the clot can extend upward into the junction between the superficial and deep venous systems. At that point the situation becomes a medical emergency.
If pain along the course of the vein has suddenly intensified, a hard tender cord has appeared, and the leg has noticeably swollen and feels warm — do not wait: see a doctor or call an ambulance that same day.
I discuss the management of thrombotic complications in more detail on the thrombosis treatment page.
Deep Vein Thrombosis and the Risk of Pulmonary Embolism
Deep vein thrombosis (DVT) is the complication phlebologists fear most. The deep veins carry the main volume of blood from the legs to the heart, and a clot within them threatens not only the limb but also the patient's life.
Why Do Varicose Veins Increase the Risk of DVT?
- Chronic blood stagnation creates conditions favorable to clot formation.
- Inflammation of superficial veins can spread to the deep veins through perforating vessels.
- Patients with varicose veins often lead a sedentary lifestyle because of leg pain and heaviness.
The most dangerous consequence of DVT is pulmonary embolism (PE): a clot breaks off and travels through the bloodstream into the lungs. This condition can be fatal. That is precisely why varicose veins are not «just leg veins» but a systemic problem that demands attention.
Bleeding from a Varicose Node
The thinned, over-stretched wall of a varicose vein offers unreliable protection. Even a minor trauma — a bump against furniture, a scratch, an awkward movement — can cause rupture of a varicose node with bleeding. In some patients this occurs right in the shower or during sleep.
What makes such bleeding particularly alarming is that it can be profuse and frightening — the veins are under high pressure, and blood can pour out forcefully. The person is often at a loss and does not know what to do.
First Aid for Bleeding from a Varicose Node
- 1Lie down and elevate the leg above the level of the heart.
- 2Apply a clean cloth and press firmly over the bleeding site.
- 3Secure a pressure bandage and immediately call an ambulance or get to a doctor.
This complication is a direct indication for surgical or minimally invasive treatment of varicose veins. Waiting further after such an episode is inadvisable.
Trophic Skin Changes and Ulcers
Years of blood stagnation damage not only the vessels but also the surrounding tissues. The skin of the lower leg and ankle begins to change gradually:
- Hyperpigmentation appears — brownish patches caused by hemosiderin deposits.
- The skin thickens and takes on a «woody» texture (lipodermatosclerosis).
- Eczema develops: itching, flaking, weeping.
- And finally — a trophic ulcer: an open wound that will not heal without specialized treatment.
A trophic ulcer is stage C6 — the final clinical class of the international CEAP classification. Treatment is prolonged, requiring dressings, compression therapy, and frequently phlebological interventions. You can read more on the trophic ulcer treatment page.
I want to emphasize: a trophic ulcer is the endpoint of years of inaction, not a sudden catastrophe. It always has warning signs, and at every stage the process can be halted.
How to Know It Is Time to See a Phlebologist Right Now
There is no need to wait for an ulcer or a bleeding episode. Reasons to schedule an in-person examination include:
- Visibly enlarged veins on the legs, even if they «cause no trouble.»
- Evening swelling, heaviness, and a bursting sensation in the calves.
- Night cramps (especially recurring ones).
- Changes in color or texture of the skin on the lower legs.
- Any episode of redness, hardening, or pain along the course of a vein.
The first step is vein duplex ultrasound (duplex scanning). This painless examination takes approximately 30–40 minutes and provides a complete picture of both the superficial and deep veins. It is the starting point for proper diagnosis and treatment planning.
Treating Early Is Easier Than Restoring Later
I often tell patients: varicose veins at an early stage mean an outpatient procedure under local anesthesia and going home the same day. Varicose veins with a trophic ulcer mean months of treatment, dressings, and restrictions. The difference speaks for itself.
Modern minimally invasive methods — EVLA, RFA, sclerotherapy — make it possible to address varicose veins without traditional incisions and lengthy recovery. They work best, however, precisely at the early and intermediate stages.
If you recognized your own symptoms in this article, or if it has simply been a long time since a specialist examined your legs — please make an appointment. I hold consultations at M-Clinic, Tashkent. Call +998 99 883-93-21 — we will find a convenient time, and if needed, home visits are available for patients with limited mobility.
Preventing a complication is always easier than treating it — and that is not merely a saying; it is the daily reality of my practice.
Frequently Asked Questions
Can varicose veins resolve on their own without treatment?
No. Varicose veins do not repair themselves — the valves inside them no longer function. Without treatment the condition progresses, though the rate varies from person to person. Compression stockings and an active lifestyle slow the process but do not address the underlying cause. A real result requires a consultation with a phlebologist and, as a rule, a minimally invasive procedure.
How dangerous is thrombophlebitis in varicose veins, and how can it be recognized?
Acute thrombophlebitis presents as redness, pain, and hardening along the course of a varicose vein, sometimes accompanied by a rise in body temperature. It is treatable in itself, but carries the risk of the clot spreading to the deep veins. For this reason, when these signs appear, a doctor should be seen that same day — do not wait, and do not attempt self-treatment.
From what age should veins be checked, and how often?
If you have a hereditary predisposition, a job that requires standing for long periods, or prolonged sitting, a first phlebologist examination is recommended as early as age 25–30. In the absence of complaints or changes, a preventive check-up every 2–3 years is appropriate. With any symptoms — swelling, heaviness, visible veins — seek evaluation promptly. Vein duplex ultrasound is a simple, informative way to confirm that everything is in order.
