Endovenous treatments
Endovenous treatments are used to occlude varicose veins without vein excision, thanks to a percutaneous venous approach. It is therefore a minimally invasive technique, achievable on an outpatient basis. The treatment is carried out at the level of the lumen of the vein.
Endovenous techniques mainly treat large saphenous veins, but can still be used for small saphenous with a suitable procedure. In order to limit the risk of deep venous thrombi, endovenous treatments are administered a few centimeters from the sapheno-femoral junction.
The occlusion of the vein is achieved by the application of a heat producing energy source. The energy sources are varied: we can mention radio frequency, lasers and steam. Energy production is possible through the use of a technology-specific generator, which then transmits its energy to a processing probe.
Varicose vein occlusion can also be achieved by injecting a sclerosing solution (foam or liquid), causing a significant inflammatory reaction, leading to obliteration of the vein.
Endovenous procedures should be performed in operating rooms and theatres or in an outpatient hospital area, including the equipment essential for this type of procedure. As mandatory equipment, there is for example the resuscitation case, essential for any act under local anesthesia.
In addition, as part of a laser treatment, specific signage specifying the use of the laser is essential outside the operating room.
During the procedure, the practitioner must be accompanied by a nursing staff. The mission of the nursing staff is to serve the sterile equipment and to handle the generator.
Since the procedure takes place on an outpatient basis, the patient walks immediately after the operation. Following the operation, tape compression is implemented. Then wearing stockings is highly recommended for 15 days. The shower is possible after 24 hours, thanks to the minimally invasive nature of the procedure.
The patient usually resumes normal activities within a few days. During the weeks following treatment, it is recommended to walk regularly while avoiding particularly strenuous activities and prolonged periods of standing.
