Letter by Ng et al Regarding Article, “Cervical Carotid Pseudo-Occlusions and False Dissections: Intracranial Occlusions Masquerading as Extracranial Occlusions”
To the Editor:
We read with interest the recent study of Grossberg et al1 on cervical carotid pseudo-occlusion (PO) showing that PO is relatively common in patients with isolated intracranial internal carotid artery occlusion. We are writing to further highlight the clinical relevance of this poorly recognized entity and the need for an alternative noninvasive diagnostic modality for early detection.
Misdiagnoses of PO as true occlusions may affect acute clinical decision making in the era of endovascular clot retrieval. When a chronic carotid occlusion is incorrectly suspected, or when a technically challenging procedure too prolonged for timely …
