Medical nomenclature has a rich tradition employing both ancient and modern languages to precisely describe our understanding of a particular medical noun. As with other storied professions, we have recognized particular luminaries by associating their names with particular conditions many times alongside a more descriptive term, which often exists in parallel. We have collectively also recognized that in many instances the understanding of a particular medical noun changes with time, rendering a prior term inaccurate. In such circumstances, ideally the field adopts a more accurate name while conscientiously relegating the former to medical archives.

In the narrow confines of neurosurgery, neurology, and neuroradiology, changes in nomenclature have been motivated by improved understanding of disease states reflected in precision of the newly adopted appellation. Numerous examples of novel nomenclature demonstrate the potential benefit, including paradigm shifts in understanding as well as treatments for a disease. For example, acoustic neuromas no longer exist, replaced with the more accurate vestibular schwannoma.1 Developmental venous anomaly has mostly supplanted the more pedestrian venous angioma.2 The dural arteriovenous malformation has been replaced by dural arteriovenous fistula (DAVF), which represents the true angioarchitectural designation. Correct nomenclature can profoundly impact treatment; when we hear about a sexagenarian with a vein of Galen malformation we know the diagnosis is most likely a vein of Galen region DAVF, with completely different ramifications. Other times we adopt new terms simply because they more accurately define the state, even though the older term is widely used and perhaps not quite inaccurate—for example, pseudotumor cerebri has been replaced by idiopathic intracranial hypertension.

This preamble, in the spirit of clinically relevant nomenclature revisions, is to contend that the vast majority of ‘thrombectomies’ in the …
