Abstract: A recanalização espontânea tardia da carótida interna é um evento incomum e pouco estudado. Os autores relatam o caso de paciente de 73 anos, masculino, hipertenso, com antecedente de acidente vascular cerebral há 3 anos, com seqüela motora e sensitiva em membro superior direito, apresentando ao mapeamento dúplex e arteriografia oclusão total da carótida interna. Evoluiu após 2 anos com novos episódios de ataques isquêmicos transitórios de repetição. Submetido a novos exames de imagem para avaliação da circula… Show more

Spontaneous recanalization of a chronically occluded internal carotid artery (ICA) is a rare occurrence. The authors report 3 patients who had documented total occlusion of the ICA followed by late spontaneous recanalization with subsequent high-grade stenosis. The patients in this series had occlusions for 11 months, 36 months, and 39 months, respectively. One patient had symptoms ipsilateral to the recanalized vessel, and 2 patients were asymptomatic. Endarterectomy was performed uneventfully in 2 patients and pathologic specimens demonstrated typical atherosclerotic plaque with patent lumens. Our experience demonstrates that although chronic recanalizations of occluded ICAs are rare, this does occur. Pathology demonstrates typical atherosclerotic plaque which appeared to have been recanalized by lysis of thrombus. The natural history of this condition is not well known and indications for intervention are not well established.

Spontaneous Recanalization of the Occluded Internal Carotid Artery

et al. 2012

Spontaneous recanalization of the occluded internal carotid artery (ICA) is more frequent than is generally believed. The timing of spontaneous recanalization remains unclear but it may occur as either an early or a late event. The aim of this case report is to emphasize the importance of spontaneous recanalization and its consequences. From September 2008 to November 2010 we prospectively followed patients with old ICA occlusion. The diagnoses of an occlusion were based on duplex scan findings and were confirmed by CT angiography and digital subtraction angiography (DSA). ICA occlusions secondary to dissection, inflammatory process, like fibromuscular dysplasia, previous stenting or endarterectomy and trauma, were excluded from the study. All patients had a scheduled carotid duplex scan every six months. Overall 65 patients were enrolled. Two patients showed evidence of spontaneous recanalization. A 55-year-old man with a known history of transient ischemic attack had occlusion in the left side ICA. He presented with another TIA eight months later. Investigations showed evidence of rcanalization of occluded ICA. This artery underwent uneventful stenting. In another patient recanalization was heralded by global aphasia and right side hemiplegia. He was a 70-year-old man with a history of recurrent TIA. Carotid duplex scan and DSA showed recanalization of the occluded left ICA accompanied by occlusion of the ipsilateral middle cerebral artery. He remained profoundly disabled with severe neurological deficits. In conclusion, spontaneous recanalization of the occluded internal carotid artery is a potentially complicated event that may lead to severe neurological disability.
