What is Sclerotherapy?

what is sclerotherapy

Sclerotherapy is a procedure used to close blood and lymph vessels. This procedure works by damaging vein walls and damaging the valve that prevents blood from continuing down the vein. As the blood continues to flow down the vein, it continues to expand, creating significant pressure in the vein. The pressure and stretching causes the healthy valve to become damaged. Blood then continues down the vein until it reaches the next healthy valve. This creates another segment of varicose veins. This is where the sclerosing agent comes in. The agent will damage the vein walls, closing the veins.

Procedure to close blood vessels and lymph vessels

Lymphatic vessels are thin-walled tubes that drain fluid from the body’s tissues and organs to the blood. They are part of the lymphatic system, which works in a complementary manner with the cardiovascular system. They are lined with endothelial cells and have a thin layer of smooth muscle called an adventitia that binds them to the surrounding tissue. Lymph vessels are primarily concerned with the propulsion of lymph, while lymph capillaries focus on absorbing interstitial fluid from the tissues. Both have valves to prevent backflow.

The lymphatic system is similar to that of blood vessels, with an inner lining made of single flattened epithelial cells, called endothelium. Lymphatics drain fluid to other parts of the body via the veins, and sometimes they travel to lymph nodes and return to the general circulation. In some instances, they become blocked by scar tissue or disease. For instance, cancer treatments can damage or scar the endothelium and block the drainage of lymph. Another cause for obstruction is infection, radiation therapy, or filariasis, which can block lymphatic ducts.

The lymphatic system is an important part of the immune system. It provides pathways for immune system cells to travel, communicate, and proliferate. The lymphatic system is also responsible for draining excess fluid from tissues. Capillaries drain plasma into the venules, while remaining fluid drains into the terminal lymphatic channels, known as lymphatic ducts. If the fluid in the tissues becomes too thick, it can lead to edema.

Lymphatic vessels contain smooth muscle cells and are divided into three types: collecting lymphatic vessels and initial lymphatics. The initial lymphatics are non-contracting vessels made of a single layer of lymphatic endothelial cells. They are surrounded by a discontinuous basement membrane. Their entry is dependent on the pressure gradient. In addition to smooth muscle cell coverage, lymphatic vessels have valves.


Sclerotherapy is a non-surgical treatment used to remove spider and varicose veins. It has been found to work well in 50 to 80% of cases. However, it is not a guaranteed cure and is not appropriate for everyone. If sclerotherapy does not work in your case, your healthcare provider may recommend an alternative treatment.

The process requires about 30 minutes and can be done on an outpatient basis. After the treatment, patients can return home and resume their normal activities. Patients are usually required to wear compression hose for the first 24 hours and for up to two weeks. They are also advised to avoid prolonged exposure to the sun and heavy lifting over thirty pounds for 48 hours.

The study was conducted by Khoury et al., who performed a prospective trial in patients with haemorrhoids. This group was matched for age, gender, and other characteristics. Sclerotherapy resulted in clinical improvement in 89.9% of patients, and in some cases, a complete cure. It also significantly improved the quality of life. Sclerotherapy is a safe and effective treatment modality, but it is important to seek the advice of a doctor before undergoing the procedure.

Another benefit of sclerotherapy is that it is noninvasive, so there are fewer complications than surgery. However, the procedure has some side effects, and the most common ones include pain, itching, and minor discoloration of the skin. In rare cases, hives may also occur. These side effects usually subside on their own. Sclerotherapy is an important treatment option for patients with superficial venous disease.

Another benefit of sclerotherapy is that the process is fast and easy. It is also safe. It has been studied in several clinical trials, but the effectiveness of the treatment depends on the type of sclerosis. Typically, the most common sclerosants are sodium tetradecyl sulfate, polidocanol, and glycerine/lidocaine/epinephrine. The last two were approved by the Food and Drug Administration for use in hyponatremia.

One study found that sclerotherapy was highly effective in treating venous malformations of the pharynx. It decreased the size of the VM on an average per patient basis and improved the Manchester score by 37.0%. Nevertheless, complications occurred in 11.6% of the cases, with 5 patients developing pneumonia and four requiring a tracheostomy.

Side effects

Sclerotherapy is a treatment that can help reduce or eliminate the appearance of varicose veins. It is performed in a doctor’s office. Before the procedure, patients should avoid vigorous exercise and heavy activity for several days. They should also avoid any medications or skin lotions that may affect the procedure. In addition, they should not take aspirin or ibuprofen for at least 48 hours prior to the procedure. However, Tylenol and other over-the-counter pain medications should not interfere with the procedure.

Common side effects include redness and itching at the injection site. These side effects usually disappear on their own after several days. In some patients, the injected area may also appear discolored or bruised. In these cases, the patient should visit their doctor to discuss the side effects. In rare cases, an ulcer may develop around the injection site, and blood clots may form in small surface veins.

While most sclerotherapy side effects are minor and will disappear quickly, severe ones require immediate medical attention. Some people may experience allergic reactions to the solution used during the procedure. However, these are rare. Other side effects may include inflammation and discomfort. The latter is especially concerning if a person has taken antibiotics prior to the procedure.

Another common side effect is brown lines near the treated area. Although they usually disappear in three to six months, some cases last for a few years and may be permanent. If you have brown lines and are concerned about your safety, you should talk to your doctor. Getting sclerotherapy done can be expensive, and if you have concerns, make sure to follow all instructions carefully.

The side effects of sclerotherapy are very rare, but they are still possible. In rare cases, blood clots may form in the treated vein. Sometimes, these clots can travel to a deeper vein in the leg. In this case, you may experience chest pain, dizziness, or shortness of breath. In some severe cases, you may even experience pulmonary embolism, which is a medical emergency. The clot can block a vital artery, which can lead to death.

Sclerotherapy is not recommended for pregnant women, but it is okay for women on birth control pills. The doctor will determine if the treatment is appropriate for your condition based on your overall health, and the location of the blood clot. The sclerotherapy procedure takes about fifteen to 30 minutes and will cause a slight sting or cramping.

Good candidates

People in their thirties and forties are generally considered good candidates for sclerotherapy. However, some individuals in their early 20s may also be suitable candidates. Your vein expert will be able to help you decide if you’re a good candidate for the procedure.

Sclerotherapy is a minimally invasive procedure that treats problematic blood vessels and varicose veins. The procedure reduces the symptoms and improves the appearance of the affected areas. It may also be used to treat hemorrhoids or other abnormal veins. In general, this procedure does not cause any complications and patients can go home shortly afterward.

While the procedure is safe and effective, there are some precautions you should be aware of. It is not recommended for pregnant women and those with a clotting disorder. People who are breastfeeding should wait 90 days before getting sclerotherapy. Those who have a needle phobia should not have the procedure performed.

Sclerotherapy is not suitable for pregnant women, but women who take birth control pills are. People with blood clots may also not be eligible for the procedure. Your doctor will evaluate your vein condition to decide whether you are a good candidate. This decision is made based on the appearance of the veins as well as the results of the ultrasound.

Patients who have varicose veins should know that sclerotherapy requires several sessions to achieve the desired results. Patients must also be realistic about their expectations and understand that there’s a high possibility of new veins developing. A successful procedure requires three to four sessions.

Sclerotherapy is a popular treatment for visible spider veins and small varicose veins near the surface of the skin. This procedure is performed by injecting a special sclerosing agent into the vein. The treatment causes the vein walls to stick together and collapse, directing blood flow to healthier veins. Eventually, the visible vein will disappear.

Patients who are a good candidate for sclerotherapy should have no medical conditions that limit their ability to undergo this procedure. In general, patients with a history of leg vein disorders should be considered for the treatment. A doctor will assess these veins and recommend the best treatment plan for their individual needs.
