A vascular malformation is a type of vascular anomaly. [2] They may cause aesthetic problems as they have a growth cycle, and can continue to grow throughout life. Vascular malformations of the brain include those involving capillaries , and those involving the veins and arteries .
Sclerotherapy (the word reflects the Greek skleros, meaning hard) [1] is a procedure used to treat blood vessel malformations (vascular malformations) and also malformations of the lymphatic system. A medication is injected into the vessels, which makes them shrink. It is used for children and young adults with vascular or lymphatic malformations.
This imprecise terminology has caused diagnostic confusion, blocked communication and even caused incorrect treatment, as it does not differentiate between various vascular anomalies. [4] However, in 1982, Mulliken introduced a classification that replaced these descriptive terms and gave direction to the management of various vascular anomalies.
An arteriovenous malformation (AVM) is an abnormal connection between arteries and veins, bypassing the capillary system. Usually congenital , this vascular anomaly is widely known because of its occurrence in the central nervous system (usually as a cerebral AVM ), but can appear anywhere in the body.
Such treatment may allow normal blood flow to resume. It is a non-surgical medical procedure and is not nearly as invasive as debulking. Ultrasound guided foam sclerotherapy is the state of the art new treatment which could potentially close many large vascular malformations. [16] [17] Compression therapies are finding more use as of the last ...
However, there have been several reported cases of arteriovenous malformations recurring. [12] The young age of many patients, the complex vascular anatomy, and the sensitive location of the Vein of Galen offer considerable challenges to surgeons. [13] Another treatment option is Radiotherapy.
Sirolimus is a relatively new medical therapy for the treatment of vascular malformations [25] in recent years, sirolimus has emerged as a new medical treatment option for both vascular tumors and vascular malformations, as a mammalian target of rapamycin (mTOR), capable of integrating signals from the PI3K/AKT pathway to coordinate proper cell ...
Treatment of PROS diseases is variable and depends on the specific disease. Curative treatment does not exist and most treatments are given to control symptoms. Overgrowth and malformations of solid tissues can be treated with surgery. Sclerotherapy can be used to treat vascular malformations. [5]
