Venaseal™ Closure System is a relatively new procedure used to treat varicose veins, a viable alternative to traditional vein stripping surgery or other minimally invasive techniques like endovenous laser therapy (EVLT). The Venaseal™ procedure is preformed in the laser vein clinic and offers a modern, effective, and patient-friendly approach to treating varicose veins by sealing them with a medical adhesive, thereby eliminating the need for traditional vein stripping surgery. 
Pre-Procedure Preparation:
- Consultation: Before the procedure, the patient undergoes a venous ultrasound at Greater Niagara Medical Imaging (GNMI) also located at 464 Welland Ave in St. Catharines. Once that ultrasound has been read a second ultrasound is preformed in the laser vein clinic. Using this information the Doctor can then assess the severity of the varicose veins and determine if Venaseal™ is an appropriate treatment.
 
- Preparation: On the day of the procedure, the patient’s leg is cleaned, and the area around the vein(s) to be treated is numbed with a local anesthetic. The patient is awake during the procedure, which is done under ultrasound guidance to ensure precise placement of the Venaseal™ adhesive.
 
- Procedure Steps:
 
- A small incision (typically less than 2mm) is made near the ankle or calf to access the vein with a catheter.
 
- A thin guidewire is inserted through the catheter and threaded up the length of the vein to be treated, under ultrasound guidance to ensure accurate positioning.
 
- Once the catheter is properly positioned within the diseased vein, the Venaseal® system is used to deliver medical adhesive (cyanoacrylate) along the length of the vein. This adhesive seals the vein shut permanently.
 
- The adhesive quickly polymerizes upon contact with blood, causing the vein walls to stick together. Over time, the treated vein becomes scar tissue that is absorbed by the body. Blood flow is naturally rerouted to healthier veins nearby. After the procedure, a bandage is applied over the tiny incision site.
 
- Unlike EVLT, only one or two anesthetic needles are required for this non-thermal ablation of the varicose vein.
 
Post-Procedure Care:
- Thigh-High Compression stockings with a 20-30mmHg must be worn for 48hours after the procedure to aid in healing and reduce swelling.
 
- Patients are usually encouraged to resume normal daily activities shortly after the procedure, with minimal restrictions compared to traditional surgery. Patients are to avoid streneous activity for 14 days after the procedure.
 
- A one-month follow-up Ultra-Sound & in-office appointment is scheduled to monitor healing and ensure the varicose vein has been effectively treated.
 
Advantages of Venaseal™:
- Minimally Invasive: Requires only a single needle stick for access and a small incision.
 
- Comfortable: Patients typically experience little to no pain during or after the procedure.
 
- Fast Recovery: Most patients can return to normal activities within a day or two.
 
- Effective: Clinical studies have shown high success rates in closing varicose veins and improving symptoms.
 
 
Considerations:
- Venaseal is generally considered safe, but like any medical procedure, it carries some risks such as the potential for allergic reactions to the adhesive or rare complications such as deep vein thrombosis.
 
- Not all varicose veins may be suitable for Venaseal treatment, and your vascular specialist will determine the best course of action based on individual circumstances.
 
- This procedure is more expensive than EVLT.
 
 
Venaseal™ Closure System is a relatively new 
procedure used to treat varicose veins, a viable 
alternative to traditional vein stripping surgery or 
other minimally invasive techniques. The 
Venaseal™ procedure is preformed in office by Dr. 
Rammohan and an ultrasound technician and offers 
a modern, effective, and patient-friendly approach to 
treating varicose veins by sealing them with a 
medical adhesive, thereby eliminating the need for 
traditional vein stripping surgery. 
Pre-Procedure Preparation:
Consultation: Before the procedure, a patient 
is typically refered to and undergoes a 
consultation with Dr. Rammohan, a vascular 
specialist, who assesses the severity of the 
varicose veins and determines if Venaseal™ is 
an appropriate course of action. An ultrasound 
Preparation: On the day of the procedure, the 
patient’s leg is cleaned and sterilized, and the 
area around the vein(s) to be treated is numbed 
with a local anesthetic. The patient is awake 
during the procedure, which is done under 
ultrasound guidance to ensure precise 
placement of the Venaseal™ adhesive.
Procedure Steps:
Dr. Rammohan makes a small incision 
(typically less than 1mm) near the varicose 
vein, usually around the knee or upper thigh 
area, to access the vein with a catheter.
A thin guidewire is inserted through the 
catheter and threaded up the length of the 
vein to be treated, under ultrasound guidance 
to ensure accurate positioning.
Once the catheter is properly positioned 
within the diseased vein, the Venaseal® 
system is used to deliver medical adhesive 
(cyanoacrylate) along the length of the vein. 
This adhesive seals the vein shut 
permanently.
The adhesive quickly polymerizes upon 
contact with blood, causing the vein walls to 
stick together. Over time, the treated vein 
becomes scar tissue that is absorbed by the 
body. Blood flow is naturally rerouted to 
healthier veins nearby. After the procedure, a 
bandage is applied over the tiny incision site.
 
Post-Procedure Care:
Thigh-High Compression stockings with a 20-
30mmHg must be worn for 48hours after the 
procedure to aid in healing and reduce 
swelling.
Patients are usually encouraged to resume 
normal daily activities shortly after the 
procedure, with minimal restrictions compared 
to traditional surgery. Patients are to avoid 
streneous activity for 14 days after the
