title: Interventional angiography in neuropediatrics.
abstract: Since the introduction of non-invasive imaging techniques (CT, US, MRI), superselective cerebrospinal angiography has been playing a major role as a diagnostic tool as well as a therapeutic procedure prior to surgery or as an alternative. Surgical neuroangiography is now also a well-established therapeutic technique in neuropediatrics. Lesions fed by the external carotid artery and spinal cord lesions are the main indications. The first group consists of maxillofacial vascular malformations, nasopharyngeal angiofibromas, and vascularized tumors of the facioorbital area (hemangiopericytoma, angiosarcoma ...). Spinal lesions for which embolization can be considered are benign tumors of the vertebral column (vertebral hemangioma, aneurysmal bone cyst ...) and vascular malformations intrinsic to the spinal cord. Particles (Ivalon, dura) are the safest embolization materials and have a wide range of possible applications; glues such as IBC have defined but limited indications. Digital subtraction angiography is crucial during the procedure and in determining the overall doses of contrast medium to be administered. Furthermore, decisions can be made more rapidly and precisely, with a definite improvement in the therapeutic results.
