What are the complications of varicose veins treated with sclerotherapy

Nowadays, there are a lot of people suffering from varicose veins. If varicose veins are not effectively treated, it will cause harm to the body. Therefore, many patients want to treat varicose veins with sclerotherapy. So, what are the complications of this treatment method? In order for you to have a comprehensive understanding, the following content makes a detailed introduction so that you can have a comprehensive understanding.

1. Esophageal ulcer The most common complication of esophageal sclerotherapy is esophageal ulcer, with an incidence of approximately 10% to 90%. This is due to the inflammatory response caused by local chemical stimulation, esophageal venous thrombosis and tissue necrosis causing esophageal mucosal damage.

2. Esophageal stenosis Esophageal stenosis is a late manifestation of EVS and can occur after a few weeks or months. The tissue inflammatory response caused by the sclerosant may be the main factor leading to esophageal stenosis. The more treatments, the larger the dose, and the more repeated injection sites along the circumference of the tube, the greater the chance of stenosis. Persistent and larger ulcers tend to heal in a fibrotic manner and are prone to esophageal stricture.

3. Esophageal perforation Perforation often occurs in deeper ulcers and trauma during examination. However, since the application of EVS, immediate perforation caused by trauma has become rare. Delayed perforation is caused by full-thickness necrosis of the esophageal wall and microabscess formation caused by the sclerosing agent, which usually occurs several days to 2 weeks after EVS. The causes of this disease are often related to excessive doses of sclerosant injected outside the blood vessels, excessively deep injections, active bleeding, and the combined use of a three-chamber two-balloon catheter for compression.

4. Esophageal hematoma EVS can cause aseptic inflammation and tissue necrosis of the esophageal mucosa, and can form submucosal ulcers and even muscular ulcers. Due to portal hypertension and coagulation disorder in patients with cirrhosis, aseptic inflammation under the esophageal mucosa can lead to hematoma formation.

Complications of varicose veins treated with sclerotherapy. After understanding the above content, I believe you also understand some of the complications of this treatment. Therefore, after a comprehensive understanding, in order to reduce complications, for many patients, you must choose a regular hospital and have the operation performed by an experienced doctor to minimize the occurrence of complications.
