If still left untreated, larger AVM could mature and result in heart failure due to fast movement of blood throughout the AVM bypassing the remainder of the body and returning quickly to the center.

Before injecting the sclerosant, VM architecture, close by anatomy, stream charge, type of venous drainage, and quantity of contrast distribution relative into the acknowledged physical appearance in the VM graphic is assessed (see
Inside a brain AVM, blood passes directly from the arteries into the veins by using tangled vessels. This disrupts The standard technique of how blood circulates through the brain.
Developmental venous anomalies and capillary telangiectasias almost never call for surgical procedure.

This minimally-invasive surgical method entails the use of an functioning microscope to conduct a microsurgery with Computer system-assisted navigation Together with the goal of totally removing the vascular malformation and protecting versus the chance of rupture.
