Microvascular Anatomy in Neuroendovascular Therapy

Abstract

  The field of view in endovascular therapy is presented as 2D images displayed on a monitor. Creating an appropriate field of view is relatively easy if the overlapping vessels can be separated and visualized. However, it is important to recognize the function of vessels, as the surrounding structures, such as the brain and nerves, cannot be visualized. Careful observation of slab maximum intensity projection images using 3D-rotational angiography or cone-beam CT can be useful for understanding the microvascular anatomy of complex vascular diseases, such as dural arteriovenous fistulas, prior to the procedure. It is also important to imagine a 3D architecture from 2D images during this procedure. This article provides an overview of the functional microvascular anatomy and imaging techniques required for safe and effective endovascular therapy.
