Introduction
Varicose veins are a common condition that can cause discomfort, pain, and cosmetic concerns. Endovenous Laser Ablation (EVLA) is a minimally invasive procedure that effectively treats varicose veins using laser energy. Dr. Parul Garg provides a detailed explanation of the step-by-step process of EVLA, ensuring patients understand the procedure and its benefits.
Preparation: Draping with Betadine
The first step in the EVLA procedure is to prepare the treatment area by draping it with Betadine. Betadine is an antiseptic solution that helps to sterilize the skin, reducing the risk of infection. The area from the groin to the ankle is thoroughly cleaned and draped to maintain a sterile environment throughout the procedure.
Ultrasound Guidance
Ultrasound guidance is crucial in the EVLA procedure. It allows the physician to visualize the varicose vein and surrounding structures in real-time. The ultrasound machine provides a detailed image, ensuring precise placement of the needle and other instruments. This step ensures the procedure’s safety and effectiveness.
Inserting the Needle and Wire/Sheath
With the assistance of ultrasound guidance, a needle is carefully inserted into the varicose vein. Once the needle is correctly positioned, a guidewire is passed through the needle into the vein. The guidewire acts as a pathway for the introduction of a sheath, which is a thin, flexible tube that facilitates the insertion of the laser fiber.
Inserting the Laser Fiber
The next step involves inserting the laser fiber through the sheath. The laser fiber is a thin, flexible tube that delivers laser energy to the varicose vein. The ultrasound machine continues to guide this process, ensuring that the laser fiber is correctly positioned within the vein.
Administering Local Anesthetic
To minimize discomfort during the procedure, a local anesthetic agent is administered. This is done by a needle, starting from the groin and extending down to the ankle. The anesthetic numbs the area, making the procedure more comfortable for the patient. It also helps to compress the vein around the laser fiber, improving the effectiveness of the treatment.
Using the Laser Machine
Once the laser fiber is in place and the local anesthetic has been administered, the laser machine is activated. The physician confirms the position of the laser fiber using ultrasound to ensure it is correctly located within the vein.
Delivering Heat Energy
The laser machine delivers controlled heat energy to the vein. This heat energy causes the vein walls to collapse and seal shut. The process begins from the point closest to the groin and continues down the length of the vein.
Withdrawing the Laser Fiber
As the heat energy is delivered, the laser fiber is gradually withdrawn. This ensures that the entire length of the varicose vein is treated. The withdrawal is done slowly and carefully, with the ultrasound machine continuously monitoring the procedure to ensure precision and effectiveness.
Conclusion
Endovenous Laser Ablation is a highly effective and minimally invasive treatment for varicose veins. Dr. Parul Garg’s step-by-step explanation highlights the precision and care involved in the procedure. By using advanced techniques such as ultrasound guidance and laser technology, EVLA provides significant relief from varicose veins with minimal discomfort and downtime.
