“…Furthermore, spontaneous recanalization (SR) may occur in patients with ICA occlusion, which may be further categorized as early or late SR, based on the cut-off duration of the mean hospitalization of these patients (usually two weeks). The results of previously published studies have indicated that early SR of an occluded ICA may occur within 1-2 h to two weeks after occlusion (1)(2)(3)(4), and early SR of the ICA appears to be common in patients with extracranial ICA occlusion caused by arterial dissection (57-68% of the evaluated cohorts) (3,(5)(6)(7)(8). However, the incidence of late SR of an occluded ICA has been reported to be markedly lower, with 2.0 and 3.8%, respectively (9,10).…”

Late spontaneous recanalization (SR) of an occluded internal carotid artery (ICA) has been rarely reported and the prognosis of affected patients remains elusive. In the present study, the incidence of late SR of atherosclerotic occlusion of the ICA and associated outcomes were assessed in a single center. A total of 36 patients with ICA occlusion, who underwent carotid artery stenting or vertebral artery stenting in arteries other than the occluded ICA, were prospectively included and followed up for ≥18 months. SR was diagnosed by color Doppler ultrasound imaging. The incidence of late SR, the functional outcome and the incidence of adverse cardiovascular events in these patients were evaluated. During the follow-up, three patients had late SR of the occluded ICA (8.3%). All patients had vascular events prior to the confirmation of late SR of the ICA. Subsequent to SR, the patients were clinically stable with preserved functional ability, based on the Modified Rankin Scale. Of these patients, one suffered from re-occlusion of the recanalized ICA without presenting with any novel significant symptoms. In conclusion, patients with late SR of the ICA appear to have preserved functional ability and favorable clinical outcomes. Large-scale cohorts are required to determine the clinical characteristics that contribute to the incidence of late SR of the ICA.

“…Of occlusion due to carotid artery dissection (CAD), early recanalization is observed in 57–69% of cases. [1] CAD is a highly dynamic process with dramatic morphological changes in the early stage of the disease; however, little is known about the radiographic findings in the initial week.…”

“…As the majority of ICA occlusions are due to atherosclerosis,[1] the differentiation between the atherosclerotic disease and CAD is important. In CAD patients, the occlusion frequently locates 2–3 cm distal to the common carotid bifurcation and has a tapered, flame-like appearance, which is consistent with the findings in CTA of our patient.…”
