Group 1: We plan to recruite patients with AVM before and after interventional sclerotherapy. An ultrasound examination with shear wave elastography as additional measurement would be taken before and

All
Age
5 Years to 40 Years
Inclusion criteria
Inclusion criteria: - Patients with arteriovenous malformations and indication for sclerotherapy - Arteriovenous malformation can occur in a variety of ways anywhere on the body, but for our study only those vascular malformations are accessible that are located on the outside of the body and have a sufficient area for sonographic examination (about 5x5cm).
Exclusion criteria
Exclusion criteria: - Patients with arteriovenous malformations that are difficult accessible for an ultrasound examination ( for example oral AVM) - AVM-Patients without medical indication for sclerotherapy - Missing informed consent
