Endovenous laser Therapy or treatment(EVLT) is a procedure that uses laser heat to treat varicose veins(swollen and enlarged veins).In which they occur most often in the legs( tight or calves ) and can develop when valves become damaged in the veins.  

Yet, in a varicose vein blood flows backward and stays in the vein. Consequently, the vein expands, stretches, and becomes twisted. Which prevents it from circulating blood effectively.   


Which laser is the best for the Endovenous Laser Therapy(EVLT)?

The EVLT procedure begins with an interventional radiologist (IR) inserting a catheter into the varicose vein. Using ultrasound to see inside the patient, the doctor guides the catheter through the vein.

Then a laser at the end of the catheter heats the walls of the vein, which closes it and this causes blood to stop flowing through the vein.

SIFSOF ‘s Research and  Development team always recommends the Medical Diode Laser System SIFLASER-1.1 to phlebologists, interventional radiologists and vascular surgeons. In which it sends a 300m W beam of radiation in the form of light that helps in the EVLT.


The SIFLASER-1.1 is Small size body case with 15w power, this mini surgery laser system has a wavelength of 532 nm, 810 nm , 980 nm and 1064 nm for choice; it can be used in the continuous as well as pulsed mode with a contact or non contact hand piece.  

Endovenous Laser Therapy usually takes around 1 hour, and most patients can resume normal activities immediately without having to be admitted to a hospital.


During the therapy, the practitioner will make a small cut or incision in the skin and insert the catheter. It will be guided into the varicose vein. Then a laser fiber will be put into the catheter. As the practitioner slowly pulls out the catheter, the laser will heat up the length of the vein.Finally the vein will close up and should eventually shrink. 

   
 After an EVLT procedure, doctors generally recommend patients wear compression socks during the recovery process to aid circulation. This decreases the amount of bruising or swelling that can happen after the procedure.Most often doctors perform an ultrasound the following week to make sure no clots have formed in the treated veins.


Moreover, patients need to take care of themselves to avoid the occurrence of post-therapy complications such as: infection, bleeding, blood clots, damage to the nerves in the treated area.etc…
