Brain AVMs
The decision to treat brain arteriovenous malformations depends on the symptoms that they cause (such as seizures or headaches). The bleeding risk is predicted by previous episodes of hemorrhage, and whether on the CTA or MRA scan the AVM appears to be deep-seated or have deep venous drainage. Size of the AVM and the presence of aneurysms appears to matter less. In HHT, some lesions (high-flow arteriovenous fistulae) tend to cause more problems, and treatment is warranted. Other AVMs may regress over time without intervention. Various modalities are available, depending on the location of the AVM and its size: surgery, radiation-based treatment and embolization. Sometimes, multiple modalities are used on the same lesion.Surgery (by craniotomy, open brain surgery) may be offered based on the risks of treatment as determined by the Spetzler–Martin scale (grade I-V); this score is higher in larger lesions that are close to important brain structures and have deep venous drainage. High grade lesions (IV and V) have an unacceptably high risk and surgery is not typically offered in those cases. Radiosurgery (using targeted radiation therapy such as by a gamma knife) may be used if the lesion is small but close to vital structures. Finally, embolization may be used on small lesions that have only a single feeding vessel. Experimental treatments
Several anti-angiogenesis drugs approved for other conditions, such as cancer, have been investigated in small clinical trials. The anti-VEGF antibody bevacizumab, for instance, has been used off-label in several studies.
Desoximetasone is a medication belonging to the family of medications known as topical corticosteroids. It is used for the relief of various skin conditions, including rashes. It helps to reduce redness, itching, and irritation. Desoximetasone is a synthetic corticosteroid, a class of primarily synthetic steroids used as anti-inflammatory  and anti-pruritic  agents. Three brand name products are available (availability depending on country):

Topicort Emollient Cream (0.25% desoximetasone)
Topicort LP Emollient Cream  (0.05% desoximetasone)
Topisolone Cream  (0.25% desoximetasone)

Usage
When using desoximetasone, some of the medication may be absorbed through the skin and into the bloodstream. Too much absorption can lead to unwanted side effects elsewhere in the body. Large amounts of desoximetasone should be avoided over large areas. It should not be used for extended periods of time. Treated areas should not be covered with airtight dressings such as plastic wrap or adhesive bandages. Children may absorb more medication than adults do. Desoximetasone is for use only on the skin and should be kept out of the eyes. Desoximetasone can also be used to treat some types of psoriasis. See also
