Sclerosant Injection.

Sclerosant is a medication typically used for the treatment of varicose veins, as it scleroses (scars) the veins and thus rid the patient of their pain and cosmetic issue of enlarged veins.

Sclerosant injections have also been used in the treatment of tendinosis (commonly referred to as “tendinitis”), as well as surrounding tendon inflammation, known as tenosynovitis. Though not well understood, in an attempt to heal the body of the tendinosis, new blood vessels and nerves grow into a diseased tendon, producing pain. Targeting these new blood vessels and nerves with sclerosant often results in relief of symptoms.

Ultrasound follow up of patients following a sclerosant tendon injection usually demonstrates decreased blood flow and an overall normal appearance of the tendon, which is associated with an improvement of symptoms.

Treatment for tendon pain.

Sclerosant injections are routinely used as a second line method of treating tendon pain at Melbourne Radiology Clinic. As for an autologous blood or platelet rich plasma injection, sclerosant may be used to treat any painful tendon.

Ultrasound guided procedure.

Scelerosant injections are performed under ultrasound guidance to accurately and safely deliver the medication into the area of abnormality.

Patients will first require a MRI or ultrasound scan to confirm that the tendon is the source of their pain.
