Fluid is injected around the vein, not into the vein. Usually it takes 5-10 injections. The skin will be anesthetized so the procedure will not be felt.

If your doctor includes sclerotherapy with thermal ablation as many of us do, the injection is guided precisely into the vein by ultrasound imaging. How many injections depends on how many veins, their size, and their
response.

The injections needed for the procedure are to put fluid around the vein to: 1. Compress the vein, forcing the blood out, 2. Protect the surrounding tissues from the heat of the laser and, 3. To numb the area. The number of injections depends on how well the fluid will tract around the vein. It varies from person to person. One patient may only need 3-5 injections, where another may need 6-10, but those injections are critical to the procedure.

Fluid is not injected into a vein prior to EVLA. It is injected along the outside of the vein and is done with a canula or long needle connected to a pump or syringe.

The tumescent anesthesia/ fluid is injected around the vein prior to using the laser . On the larger thigh vein it generally take 5 or so injections.

No fluid is injected into the vein. Dilute anesthetic fluid is injected
surrounding the vein to accomplish4 important goals: anesthesia, push surrounding structures away, collapse the vein, and act as a heat sink. This is done with ultrasound guidance and amount depends on the
length being treated.

Local anesthesia is injected around the vein not in the vein.

No fluid is actually injected into the vein prior to ablation. You will receive very small topical injections with local anesthetic which surround the vein like a "sleeve." The number varies on the length of vein to be treated. These are easily tolerated by most patients

The fluid that is injected is called tumescent anesthesia and it is injected around the vein not into the vein. It can be injected by hand or by a power injector. Both work equally well. The purpose of the tumescent is to give anesthesia, to cushion the vein from the skin so that the laser will not burn the skin and to compress the vein so as to create a smaller surface area for the laser to work.

It's injected around the vein, to provide anesthesia. Generally can be done with 2 or 3 puncture sites.

Fluid is not actually injected into the vein during endovenous ablation. A
small amount of local anesthesia is injected into the skin at the proposed
site of entry which is usually below the knee on the inside of the leg if
closing the great saphenous vein. Using ultrasound guidance a needle is
inserted into the vein and a very small guidewire is threaded into the vein,
the needle is replaced with a small IV and the guidewire then removed.
Next, either a laser or the Venefit catheter is inserted into the vein
through the IV and carefully advanced up the vein under ultrasound
monitoring. The tip of the catheter is positioned about 1 inch from the
junction of the great saphenous vein with the deeper veins (common femoral
vein) also called the saphenofemoral junction. Several areas along the
course of the vein are numbed up with local anesthesia and this is where the
placement of fluid AROUND (not inside) the vein is performed. Starting at
the lowest point of entry, fluid is injected under ultrasound guidance
around the vein creating a column of fluid circumferentially. This
effectively empties the vein of all blood and leaves the wall of the vein
collapsed around the laser or radiofrequency catheter. This column of
liquids serves a second very important function of absorbing the leftover
heat from the catheter after it "cooks" the vein. After the catheter is
withdrawn from the vein and removed from the patient's leg along with the
introducer IV, Band-Aids are applied to the needle puncture sites and
compression hose are placed and the patient can walk on their own to their
loved ones waiting in the lobby. So, a fairly long winded answer to your
question, but I thought a more thorough answer was warranted to help you
understand the general steps of the closure procedure.

Usually 3-4 injections for the local anesthetic. No more.
