By sealing problematic veins with medical adhesive, this treatment presents an innovative alternative to conventional procedures. Though it is a highly effective treatment, there remains a degree of hesitation among patients largely due to concerns about potential VenaSeal complications. To help clear up these concerns, let’s take a closer look at the most commonly known complications, providing a clearer understanding of the treatment and highlighting the reasons why it’s considered a worthwhile option for many. But before we get into these details, let’s first delve into what exactly VenaSeal is and how it differs from other varicose vein treatments.

A Minimally Invasive Solution for Varicose Veins


VenaSeal is a groundbreaking treatment for varicose veins that employs a unique medical adhesive to effectively seal off the affected vein, seamlessly redirecting blood flow to healthier veins nearby. This innovative approach not only treats the problem vein but also enhances venous health by utilizing the body’s natural pathways.

The procedure starts by inserting a small tube, guided by ultrasound, into the affected vein through a tiny opening. Once in place, a medical adhesive is introduced into the vein through this tube. The doctor then applies external pressure to the vein, initiating the vein walls’ adhesion. This step commences the vein closure process. The vein’s complete and permanent closure usually unfolds over the subsequent months, as the body naturally responds to the treatment. Over time, the body forms scar tissue around the adhesive, ensuring the vein remains closed permanently. This closure helps to redirect blood flow to healthier veins, improving your overall blood circulation.

Top 4 Complications of VenaSeal


While the idea of internally sealing a vein might raise concerns, the reality is VenaSeal has been proven to be a safe and effective procedure. Let’s address the potential complications and uncover why they are much less worrisome than they may seem.


Allergic Reaction


If someone has had allergies to medical adhesives in the past, they might feel cautious about choosing this treatment. VenaSeal allergic reactions are usually because of a sensitivity to the cyanoacrylate adhesive used. However, it’s important to know that such reactions are fairly uncommon, affecting only about 10% of patients. The good news is that most of these reactions are mild and can be handled without seeing a doctor. And while severe reactions can happen, they’re not a frequent occurrence.


For those experiencing mild symptoms like itching or hives, over-the-counter antihistamines can be effective in providing relief. If you suspect that you’re having a severe VenaSeal allergic reaction, seek medical attention immediately.

Phlebitis is a troublesome inflammation in your veins that brings unwelcomed pain, swelling, and redness. Phlebitis after VenaSeal may be caused by the adhesive used, as your body might respond to the glue or the sealed vein as if it were an unwelcome intruder. While phlebitis is the most common complication, occurring in 4% to 20% of cases, it usually resolves within an average of 5 days. To effectively combat phlebitis after VenaSeal, a range of treatments are available:

  • Blood thinners to prevent clot enlargement
  • Compression stockings
  • Warm or cold compresses
  • Over-the-counter drugs
  • Anti-inflammatory medications


Deep Vein Thrombosis


Deep vein thrombosis, or DVT, is a serious form of venous inflammation that occurs when blood clots form in deeper veins, usually in the leg. While the risk of DVT from VenaSeal is low, it varies per individual. Before opting for this treatment, it’s crucial to sit down with your healthcare provider for a tailored risk assessment. This step helps determine if VenaSeal could potentially trigger DVT.


Pulmonary Embolism


This condition is a sudden blockage in the pulmonary arteries leading to the lungs, often due to a blood clot from DVT in the leg. Experiencing a pulmonary embolism from VenaSeal is rare. However, it is a critical condition that demands immediate attention. If you find yourself experiencing symptoms such as shortness of breath, chest pain that intensifies during deep breaths, coughing up blood, rapid heartbeat, or fainting, it’s imperative to seek emergency medical care without delay. 

Do the Benefits of VenaSeal Outweigh the Potential Complications?


The answer is a definite yes when it comes to the benefits of VenaSeal! This treatment is not only quick, taking just about 60-90 minutes, but also highly convenient as it can be done on both legs during one appointment—perfect for those with busy schedules. VenaSeal’s effectiveness is noteworthy, with a stunning 98% of patients achieving total vein closure within six months, and a remarkable 94.6% success rate after five years. 


The procedure itself is straightforward and minimally invasive. You’ll be awake the whole time, and the most you might experience from the local anesthesia is mild bruising or itching. Another perk is that there’s no need to stop your regular medications before or after undergoing VenaSeal. The recovery period is brief, typically requiring only a few days to get you back on your feet.

VenaSeal: Your Path to Varicose Vein Freedom


The allure of VenaSeal lies in its benefits, far outweighing potential risks. Although there is a possibility of experiencing phlebitis and allergic reactions, they are usually mild. The likelihood of experiencing more serious VenaSeal complications like DVT and Pulmonary Embolism is exceptionally low. With its proven track record of success, rapid recovery, and undeniable convenience, VenaSeal is a prime option for those pursuing relief from varicose veins.
