Besides the superficial large-diameter veins, the most feared clot is not in the superficial vein, but in the deep vein. We call this Deep Vein Thrombosis (DVT). The risk of this is less than 1% in all foam treatments. Most of them are asymptomatic, that is, asymptomatic. The rate of those giving symptoms is as low as 0.02%-.6%4%. Let's make one point clear here, this rate is even lower in superficial capillaries and small diameter vessels. You don't need to worry about this when most of the patients are in this group.
The name below-knee posterior calf muscle is seen in the gastrocnemius middle vein. In foam treatments applied to the posterior section below the knee, the vein called Small Saphenous Vein may also be thrombosis. Clot formation in these veins, which we all fear, followed by pulmonary clotting is a "pulmonary embolism" event. This is a very serious situation. Life-threatening is the prevalence of the clot going to the lung. Pulmonary Embolism was seen in only 1 case out of 1025 cases. No Pulmonary Embolism was seen in 12 173 cases in one large French study. What to do to avoid such a troublesome situation?
Excessive foam treatment should not be done: The risk increases as the volume increases. I will share the other figures related to this later. Few decisions, most losses. The risk is increased when more than roughly 10 ml is given. - The risk increases with foam treatment applied to veins larger than 5 mm. The general recommendation should be 1.5 – 2.0 ml. - Injecting large diameter veins in the inguinal region also increases the risk. - 5-10 minutes after treatment. It is recommended to return to normal movements after the elastic bandage is wrapped after rest. Simple walking with movement, especially the movements of the foot as if pressing the pedal, are effective.
- There are researchers who draw attention to the importance of the night bandage. - Routine coagulation tests are not recommended for foam treatment. - Low Molecular Weight Heparin for prevention is recommended only in high-risk cases. - Clot in Superficial Veins: Thrombophlebitis & Thrombosis: It is seen in 4.7%.
Other rare complications:
- Nerve Damage
- Transient limb edema and lymphedema.
- Matting: New vessel formation (repetition) is more common in men. It occurs in 4-6 weeks. It is most common in the knee and calf region. These pass within 3-12 months. In this case, you have to wait patiently.
-
IF YOU ARE FEAR OF RECURRING YOUR HERCESIS, YOU MUST KEEP IN MIND: YOU DON'T HAVE AN ULTRASOUND. IF THE BASIC REFLUX (LEAK) is skipped, the risk of recurrence is HIGH.
- Staining: 10-30% is seen. It occurs in 3-4 weeks. It doesn't happen right away. It takes up to 6-12 weeks. 10% are permanent. It is likely to be permanent after 1 year.
- Fainting: Vasovagal reflex. It is a benign condition that develops after any surgical procedure. It can develop even while being needled. It is seen as a simple fainting. It develops with nausea, vomiting and sudden loss of consciousness in patients. Additional symptoms such as dizziness and hot flashes may occur. The point to be noted is; sudden falls and injuries. After the procedure, 5-10 minutes of rest becomes even more important in this respect.
Stay well.
