1. Spontaneous recanalization of thromboembolic vascular occlusions is common in stroke patients. The rate of spontaneous recanalization is 5%-30% with most of the reports of intracranial vascular occlusion. Spontaneous thrombolysis after occlusion of the extracranial carotid may occur just as frequently. 4D CT perfusion exam offers fast and accurate hemodynamic evaluations of the vascular anatomy and possibly associated brain infarction or ischemic penumbra. This review adds help in recognizing this entity.
2. Little is known about the mechanism, natural course, and the long-term clinical outcome of the observed spontaneous recanalization of internal carotid artery occlusion. Such background literatures were reviewed through this case exhibit which can spike future interest in collecting and analyzing those cases for better stroke management.
3. This review illustrates the importance of routine imaging follow ups after the diagnosis of complete occlusion of internal carotid artery by using noninvasive carotid Doppler ultrasound or CTA, even after the spontaneous recanalization.
