Doctors who perform endovascular surgery must have an excellent command of two different specialties: [[neurosurgery]] and [[radiology]]. Depending on their backgrounds, doctors who perform endovascular neurosurgery are called either [[endovascular neurosurgeon]]s, [[interventional neuroradiologist]]s or [[interventional neurologist]]s. Endovascular neurosurgeons trained originally as [[neurosurgeon]]s and then received specialized training in radiology. Interventional neuroradiologists trained originally as radiologists and then received specialized training in neurosurgery. Interventional neurologists trained originally in [[neurology]] followed by training in endovascular neurosurgery. In fact, endovascular neurosurgery itself goes by an array of names: [[neuroendovascular surgery]], [[neurointerventional surgery]], [[interventional neuroradiology]] and [[endovascular surgical neuroradiology]], for example.
