What are the main causes of varicose veins and spider veins?

Varicose veins and spider veins develop when valves in the veins become weakened or damaged, causing blood to pool. Common causes include genetics (family history), aging, pregnancy, prolonged standing or sitting, obesity, and hormonal changes. Women are more susceptible due to hormonal fluctuations during pregnancy, menopause, or from birth control use.

How do I know if I need treatment for my varicose veins?

You should consider treatment if you experience symptoms such as leg pain, aching, heaviness, swelling, cramping, restless legs, skin discoloration, or itching around the veins. Even without symptoms, large or bulging varicose veins may benefit from treatment to prevent complications. A consultation with Dr. Figueroa at VeinCentre can determine if treatment is right for you.

What is sclerotherapy and how does it work?

Sclerotherapy is a minimally invasive treatment where a specialized solution is injected directly into spider veins or small varicose veins. This solution irritates the vein walls, causing them to collapse and seal shut. Blood is then rerouted through healthier veins, and the treated vein is gradually absorbed by the body over several weeks. It's highly effective with a 90%+ success rate.

Are varicose vein treatments covered by OHIP?

Yes, consultations at VeinCentre are OHIP-covered. Treatment coverage depends on medical necessity. If your varicose veins cause symptoms like pain, swelling, or skin changes, treatments like radiofrequency ablation or VenaSeal may be covered by OHIP. Cosmetic treatments for spider veins are typically not covered. Dr. Figueroa will assess your condition and discuss coverage options during your consultation.

How long does a typical vein treatment appointment take?

Treatment duration varies by procedure type. Sclerotherapy typically takes 30-45 minutes, VenaSeal Glue Ablation takes 30-45 minutes, and Radiofrequency Ablation (RFA) takes 45-60 minutes. These are outpatient procedures performed in our Toronto or Richmond Hill clinics, allowing you to return home the same day.

Is vein treatment painful?

Modern vein treatments are minimally invasive and well-tolerated. Local anesthesia is used to numb the treatment area, so you'll feel minimal discomfort during the procedure. Most patients describe feeling only slight pressure or mild sensations. Sclerotherapy involves small needle injections that feel like tiny pinches. Post-treatment discomfort is typically mild and manageable with over-the-counter pain relief.

What is the recovery time after vein treatment?

Recovery is quick with modern vein treatments. Sclerotherapy and VenaSeal allow immediate return to normal activities with no compression stockings required after VenaSeal. Radiofrequency Ablation typically requires 1-2 days before returning to work and wearing compression stockings for 1-2 weeks. Walking is encouraged immediately after all procedures to promote healing. Most patients resume regular activities within days.

Can varicose veins come back after treatment?

Treated veins do not reopen once successfully closed. However, new varicose veins can develop in other areas over time due to ongoing genetic factors, aging, or lifestyle conditions. The recurrence rate is low with modern treatments—RFA and VenaSeal have 95%+ success rates. Maintaining a healthy weight, staying active, and wearing compression stockings when needed can help prevent new vein problems.

How many treatment sessions will I need?

The number of sessions depends on the severity and extent of your vein condition. Many patients see significant improvement after just one treatment session. Spider veins may require 2-3 sclerotherapy sessions spaced several weeks apart for optimal results. Larger varicose veins treated with RFA or VenaSeal typically require only one session per vein. Dr. Figueroa will create a personalized treatment plan during your consultation.

What should I expect during my first consultation?

During your OHIP-covered consultation at VeinCentre, Dr. Figueroa will review your medical history, examine your legs, and may perform an ultrasound to assess vein health and blood flow. You'll discuss your symptoms, treatment goals, and concerns. Dr. Figueroa will explain which treatment options are best suited for your condition—whether sclerotherapy, radiofrequency ablation, or VenaSeal—and answer all your questions about the procedure, recovery, and expected results.

How to Reduce the Appearance of Spider Veins: Non-Surgical Options in Toronto & Richmond Hill

May 15, 2025

5 min read

Updated: Aug 27

Spider veins, clinically known as telangiectasias, are small, dilated capillaries and venules situated directly beneath the superficial layer of the skin. Measuring between 0.5 mm and 1.0 mm in diameter, they present as web-like, branching clusters of red, blue, or purple vessels across the legs, ankles, and face.

While frequently dismissed as a purely cosmetic concern, spider veins often serve as the earliest visible indicator of underlying venous hypertension and Chronic Venous Insufficiency (CVI).

For patients across Toronto, Richmond Hill, and the Greater Toronto Area (GTA), modern vascular medicine offers effective, non-surgical, and minimally invasive treatments that permanently eliminate spider veins with zero downtime.

This comprehensive clinical guide, created by board-certified Vascular Surgeon Dr. Luis Figueroa at VeinCentre, explains the biological causes of spider veins, the anatomical differences between spider and varicose veins, the gold-standard non-surgical treatments (including visual sclerotherapy and transdermal lasers), post-treatment recovery protocols, and OHIP-covered diagnostic care.

1. Spider Veins vs. Varicose Veins: Understanding the Clinical Differences

Although both conditions stem from venous vascular dysfunction, they differ significantly in vessel anatomy, depth, and clinical implications:

Diagnostic Comparison Table

Diagnostic Feature	Spider Veins (Telangiectasias)	Reticular Veins ("Feeder Veins")	Varicose Veins
Vessel Diameter	0.5 mm to 1.0 mm	1.0 mm to 3.0 mm	Greater than 3.0 mm
Anatomical Depth	Intradermal (Superficial dermis)	Subdermal layer	Subcutaneous tissue
Visual Presentation	Flat, web-like, red/purple lines	Blue-greenish branching networks	Bulging, tortuous, ropelike cords
Primary Underlying Cause	Local capillary pressure / Feeder reflux	Incompetence of subdermal tributaries	Saphenous vein valve failure (GSV/SSV)
CEAP Clinical Stage	C1	C1	C2 to C6
Primary Treatment	Visual Sclerotherapy / Nd:YAG Laser	Foam Sclerotherapy / Micro-injections	Endovenous Ablation (VenaSeal, EVLA, RFA)

2. Common Causes and Risk Factors for Spider Veins

Spider veins develop when the microscopic, unidirectional valves inside superficial venules weaken or fail. This valve incompetence allows blood to pool backward (retrograde reflux), increasing hydrostatic pressure and forcing delicate capillary walls to expand and become visible through the skin:

Genetic Predisposition: Over 80% of patients with spider veins have an immediate family history of venous disease.
Hormonal Fluctuations: Elevated estrogen and progesterone levels during pregnancy, puberty, menopause, or from oral contraceptives relax the smooth muscle lining of venous walls.
Prolonged Standing or Sitting: Occupations requiring prolonged immobility (healthcare workers, teachers, hospitality staff, corporate desk workers) impair the calf muscle pump mechanism.
Age-Related Vascular Changes: As veins age, elasticity declines and vessel walls thin, increasing susceptibility to microvascular dilation.
Sun Exposure and Skin Trauma: Ultraviolet (UV) radiation breaks down dermal collagen and elastin, exposing superficial vessels, particularly on the face, nose, and upper legs.
Underlying Venous Reflux (C1 / C2 Incompetence): Up to 40% of spider vein clusters are fed by deeper, incompetent "feeder" reticular veins or saphenous reflux.

3. Gold-Standard Non-Surgical Treatments in Toronto

A. Visual Micro-Sclerotherapy (The Gold Standard)

Sclerotherapy remains the internationally recognized gold-standard treatment for lower extremity spider veins and reticular veins.

How It Works: Using an ultra-fine 30-gauge micro-needle, a certified vascular specialist injects a specialized liquid sclerosing solution (such as Polidocanol or Sodium Tetradecyl Sulfate / STS) directly into the vessel lumen.
Mechanism: The sclerosant displaces blood and irritates the vessel endothelium, causing controlled cellular closure. Over 4 to 8 weeks, the closed vessel is naturally broken down and absorbed by the body.
Session Details: Treatments typically take 15 to 30 minutes in-office. Most patients achieve 80% to 90% clearance of visible vessels within 2 to 4 sessions.

B. Transdermal Laser Therapy (Long-Pulsed Nd:YAG 1064 nm & VBeam)

For tiny, ultra-fine facial spider veins, broken capillaries around the nose and cheeks, or vessels too small to cannulate with a micro-needle:

Mechanism of Action: Emits focused light energy at targeted wavelengths (595 nm or 1064 nm), selectively absorbed by intravascular hemoglobin (selective photothermolysis). The thermal energy coagulates the vessel without damaging adjacent epidermal tissue.
Integrated Skin Cooling: Advanced contact cooling tips protect the surface skin and ensure high patient comfort during pulse delivery.

C. Ultrasound-Guided Foam Sclerotherapy (UGFS)

When spider veins are fed by deeper, non-visible reticular veins or saphenous tributaries:

Sclerosant is agitated with sterile gas into a microfoam consistency and guided under direct real-time duplex ultrasound visualization to target the exact source of venous hypertension.

4. The Critical Role of a Diagnostic Duplex Ultrasound

Treating spider veins without evaluating underlying venous hemodynamics is the single leading cause of treatment failure and rapid spider vein recurrence.

At VeinCentre, board-certified Vascular Surgeon Dr. Luis Figueroa performs a comprehensive vascular evaluation:

If a patient presents with spider veins accompanied by leg heaviness, nocturnal cramping, or ankle swelling, an OHIP-covered Lower Extremity Venous Duplex Ultrasound is requisitioned.
Addressing the underlying "feeder" saphenous reflux (via minimally invasive endovenous ablation like VenaSeal Medical Adhesive or Radiofrequency Ablation) permanently eliminates the high hydrostatic pressure feeding the surface spider veins.

5. Post-Treatment Protocol: Maximizing Results and Preventing Recurrence

Following sclerotherapy or transdermal laser therapy, adhering to a structured recovery protocol ensures rapid healing and prevents post-inflammatory hyperpigmentation:

Prescription Compression Therapy: Wear graduated medical compression stockings (20 to 30 mmHg) for 3 to 7 days post-treatment to maintain vein apposition and accelerate absorption.
Immediate Walking: Walk for 15 to 20 minutes immediately following the procedure to stimulate deep venous flow and activate the calf muscle pump.
Avoid High Heat: Refrain from hot baths, saunas, hot tubs, and intense heavy weightlifting for 48 to 72 hours to prevent vasodilation of treated vessels.
Sun Protection: Apply broad-spectrum SPF 50+ to treated areas to prevent hyperpigmentation (hemosiderin staining) while micro-bruising resolves.

6. Frequently Asked Questions (FAQ)

Does sclerotherapy for spider veins hurt?

Most patients describe the sensation as a minor pinprick or mild mosquito bite. Because modern sclerosing agents like Polidocanol possess inherent mild anesthetic properties, the procedure is very well tolerated without requiring local anesthesia.

Are spider vein treatments covered by OHIP in Ontario?

Isolated cosmetic spider vein sclerotherapy is considered an elective aesthetic procedure and is not covered by OHIP. However, the initial vascular consultation with a vascular surgeon, diagnostic duplex ultrasound scans, and endovenous treatments for underlying saphenous venous disease are 100% covered under the Ontario Health Insurance Plan (OHIP) with a physician referral.

How long does it take for spider veins to completely disappear?

Treated spider veins generally fade over a period of 4 to 8 weeks. Larger reticular vessels may take up to 3 to 4 months for complete metabolic clearance.

Can spider veins come back after treatment?

Veins successfully closed by sclerotherapy are permanently reabsorbed and cannot reopen. However, because venous disease is chronic and progressive, new spider veins may develop over time in untreated areas due to genetics or lifestyle factors. Periodic maintenance treatments can keep legs clear.
