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.

Comprehensive Comparison of Endovenous Laser Treatment and VenaSeal Glue Ablation for Varicose Vein Management

5 min read

Varicose veins commonly cause discomfort and cosmetic concerns. Endovenous Laser Ablation (EVLA) and VenaSeal Glue Ablation are minimally invasive options. This article summarizes procedural mechanisms and compares effectiveness, safety, recovery, and cost considerations to support informed treatment choice.

Key Takeaways

EVLA and VenaSeal are minimally invasive treatments for varicose veins.
EVLA reports high technical occlusion rates (~95–98%) versus VenaSeal (~85–95%).
EVLA is generally used for veins up to 10 mm; VenaSeal is typically recommended for veins up to 8 mm.
Both have acceptable safety profiles but different specific risks.
EVLA recovery is commonly 1–2 weeks; VenaSeal often allows return to activities within days.
EVLA uses thermal energy; VenaSeal uses cyanoacrylate adhesive.
Patient vein anatomy, recovery priorities, and allergy history guide selection.
Coverage for each procedure varies by insurer and indication in Ontario.

Comparison of Endovenous Laser Treatment (EVLA) and VenaSeal Glue Ablation for Varicose Vein Management

EVLA and VenaSeal both occlude incompetent veins but use different mechanisms, devices, and peri-procedural steps. Below, we summarize effectiveness, safety, recovery, and practical considerations.

A comparative study examined occlusion rates, pain, complications, and time to return to activities for EVLA versus VenaSeal.

EVLA vs. VenaSeal: Efficacy, Safety, and Recovery for Varicose Veins This study compared Endovenous Laser Ablation (EVLA), under regional anaesthesia with VenaSeal for the treatment of lower limb varicose veins. The assessment looked at occlusion rates, pain levels during and after the procedure, changes in r-VCSS and AVVQ scores, complications, time to return to activities, and ulcer healing rates. Comparison Of The Safety And Efficacy Of Endovenous Laser Ablation Under Ultrasound Guided Regional Nerve Blocks With Cyanoacrylate Glue Ablation (VenaSeal), 2025

Effectiveness:

Effectiveness is measured by technical occlusion, symptom relief, and suitability for vein size. Reported device performance and indications guide the choice for specific anatomy.

Treatment	Effectiveness Rate	Suitable Vein Size
EVLA	95–98%	Up to 10 mm
VenaSeal	85–95%	Up to 8 mm
Both	High success for symptom relief	Depends on the patient's anatomy

EVLA has a modest technical advantage; clinical factors and patient goals should guide selection. For consultation options, VeinCentre offers specialist assessments.

Safety:

Safety profiles differ by modality and patient comorbidity. A review of medical history and risk factors is essential before treatment.

EVLA: Commonly bruising and site pain; rare risks include nerve injury, skin burns, and deep vein thrombosis.[1]
VenaSeal: Lower thermal discomfort but potential for adhesive-related allergic reaction and phlebitis.[2]

Both are safe for appropriate candidates when performed by experienced teams. VeinCentre provides both treatments at specialist centres in Richmond Hill and North Toronto Surgical.

Recovery Time:

Recovery influences return-to-work and activity planning.

EVLA: Typical recovery 1–2 weeks; compression stockings often prescribed and strenuous activity limited initially.[1]
VenaSeal: Faster return to routine activities—often within days—with simpler aftercare and no need for compression stockings.[2]

What Are the Procedural Differences Between EVLA and VenaSeal Glue Ablation?

EVLA applies laser energy via an intravascular fibre to thermally ablate the vein wall. VenaSeal delivers a cyanoacrylate adhesive to bond the vein walls and occlude the lumen. These differences affect anesthesia choice, intra-procedural steps, and aftercare.

How Does Endovenous Laser Ablation Function in Treating Varicose Veins?

EVLA induces a controlled thermal injury to collapse and seal the target vein. Blood is redirected through competent collaterals after occlusion.[1]

What Is the Mechanism of Action for VenaSeal Glue Vein Closure?

VenaSeal deposits medical adhesive to bond opposing vein walls and close the lumen; the treated vein is gradually resorbed while flow reroutes through remaining veins. Patients often report less intra-procedural discomfort than with thermal methods.[2]

What Are the Clinical Benefits and Risks Associated with EVLA and Glue Ablation?

Both methods improve symptoms and appearance. Choice depends on vein size, anatomy, and patient priorities such as downtime and pain tolerance.

Studies report similar quality-of-life gains at mid-term follow-up for both techniques.[3]

VenaSeal vs. EVLT: Quality of Life Improvements for Varicose Veins VenaSeal™ and EVLT both provide similar QoL improvements in patients with varicose veins at six months of follow-up. Quality of Life of Patients Treated with VenaSeal™ versus Endovenous Laser Treatment for Varicose Veins: A Retrospective Cohort Study, 2024

EVLA: High effectiveness, minimal scarring; rare nerve injury, skin burns, and thrombosis are risks.[1]
VenaSeal: Quicker recovery and less pain; adhesive hypersensitivity and phlebitis are specific concerns.[2]

Discuss the benefit–risk balance with your vascular specialist to align treatment with clinical goals and comorbidities.

What Are the Efficacy and Safety Profiles of Endovenous Laser Treatment?

EVLA has documented success rates up to about 98% and a well-established safety record; most adverse events are minor when performed in experienced centres.[1]

How Do the Benefits and Potential Complications of VenaSeal Compare?

VenaSeal offers shorter downtime and reduced procedural discomfort. Adhesive-related hypersensitivity and phlebitis are uncommon complications. When vein anatomy fits device indications, VenaSeal is a reasonable option.[2]

How Do Recovery Times and Aftercare Requirements Differ Between EVLA and VenaSeal Procedures?

EVLA typically requires short rest and compression therapy; VenaSeal usually permits earlier ambulation and less restrictive aftercare. Choose based on functional needs and clinical suitability. Published outcome comparisons help stratify post-procedural expectations by modality.[3]

Comparing Post-Procedural Outcomes of EVLA and VenaSeal for Varicose Veins They were categorized according to treatment option into two equal groups; group A (Endovenous Laser ablation (EVLA) group) and group B (VenaSeal group).

What Is the Typical Recovery Process Following Endovenous Laser Ablation?

After EVLA, light walking and compression stockings are recommended. Many patients return to sedentary work within a week; high-intensity exercise should wait until clinical clearance.[1]

What Are the Post-Procedure Care Guidelines for VenaSeal Glue Ablation?

VenaSeal care emphasizes immediate ambulation and early return to routine activities. Monitor for signs of adhesive reaction or other complications during recovery.[2]

What Are the Insurance Coverage and Consultation Options for EVLA and Glue Ablation in Ontario?

Coverage varies by payer and clinical indication. Patients should confirm benefits and prior authorization requirements with their insurer before scheduling treatment.

Is Endovenous Laser Treatment Covered by OHIP, and What Is the Consultation Process?

OHIP may reimburse EVLA for eligible indications. Consultations include history, examination, and duplex ultrasound as needed, performed by a vascular specialist to plan management. See Dr. Luis Figueroa for specialist care information.

How Does OHIP Coverage Apply to VenaSeal Glue Ablation and Patient Access?

VenaSeal coverage under OHIP depends on clinical need and local policy. Discuss eligibility and documentation with your provider. For general information on options, visit VeinCentre's website.
