A case of cerebral hyperperfusion following spontaneous recanalization of occluded middle cerebral artery
نویسندگان
چکیده
BACKGROUND Cerebral hyperperfusion syndrome (CHS) and reperfusion injury are distinct pathological phenomena. CASE SUMMARY We present the case of a young ischemic stroke patient with middle cerebral artery (MCA) occlusion and spontaneous recanalization. Follow-up transcranial Doppler ultrasound showed high velocity flow in the left MCA, and neuroimaging revealed infarction, brain edema, artery dilatation, and hyperperfusion, consistent with both CHS and reperfusion injury. CONCLUSION In cases with signs of both CHS and reperfusion injury, we speculate that CHS may be both a contributor to and a manifestation of reperfusion injury.

Late Spontaneous Recanalization of Chronic Middle Cerebral Artery Occlusion
Early spontaneous recanalization of the middle cerebral artery in acute ischemic phase artery is not uncommon, whereas the late spontaneous recanalization of chronic occluded artery is a very rare phenomenon and exact incidence and the timing of this event have not been quantified. We present a case in which late spontaneous recanalization of long-lasting middle cerebral artery occlusion occurr...
متن کاملSpontaneous recanalization after complete occlusion of the common carotid artery with subsequent embolic ischemic stroke.
INTRODUCTION Acute carotid artery occlusion carries a high morbidity and mortality. Acute angioplasty and stenting is a feasible option with little known about the long term outcome. Limiting factor for this approach is hyperperfusion syndrome or hemorrhagic infarction. Spontaneous early or late recanalization for extracranial vessel is in the range of 5% -30%, with no well defined clinical out...
متن کاملSpontaneous recanalization of the occluded internal carotid artery. A report of two cases.
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 foll...
متن کاملThe Time of Maximum Post-Ischemic Hyperperfusion Indicates Infarct Growth Following Transient Experimental Ischemia
After recanalization, cerebral blood flow (CBF) can increase above baseline in cerebral ischemia. However, the significance of post-ischemic hyperperfusion for tissue recovery remains unclear. To analyze the course of post-ischemic hyperperfusion and its impact on vascular function, we used magnetic resonance imaging (MRI) with pulsed arterial spin labeling (pASL) and measured CBF quantitativel...
متن کاملFatal cerebral hemorrhage early after subclavian artery endovascular therapy.
We report a case of cerebral hyperperfusion syndrome complicated by a fatal intracranial hemorrhage as a consequence of endovascular recanalization of an occluded left subclavian artery. This entity is thought to be secondary to the failure of the normal autoregulatory mechanism controlling cerebral blood flow after recanalization. Patients at risk for this relatively rare complication are not ...
