Understanding on distinct subsets of endothelial progenitor cells may provide insights of endothelial dysfunction or repair in the acute ischemic event. Recent in vitro data have reported the colony-forming unit (CFU) and outgrowth cell population as a subset of endothelial progenitor cells. In this study, we undertook to validate the significance of CFU number and outgrowth cell yield in acute stroke. ⋯ CFU number may thus represent an accumulated endothelial progenitor cell dysfunctional status, whereas outgrowth cell appearance may reflect the resilience of the systemic circulation to acute ischemic stress.

For selected stroke patients, intra-arterial thrombolysis (IAT) has been shown to be an effective treatment option. However, knowledge of safety and efficacy of IAT in patients with acute stroke as a complication of arterial catheter interventions is limited. ⋯ In acute stroke attributable to arterial catheter interventions, IAT is feasible and has the potential to improve outcome in these patients. A high recanalization rate could be achieved.

Clinical and tissue response to intravenous thrombolysis in tandem internal carotid artery/middle cerebral artery occlusion: an MRI study.
The benefit of intravenous thrombolysis in tandem internal carotid artery (ICA)/middle cerebral artery (MCA) occlusion remains unclear. We studied clinical and imaging outcome of intravenous thrombolysis in MRI-selected patients with tandem ICA/MCA occlusion as compared to isolated MCA occlusion. ⋯ The presence of tissue at risk appears to play a key role for the likelihood of clinical recovery after intravenous tissue plasminogen activator treatment in acute stroke patients with tandem ICA/MCA occlusion. There appears to be no evidence to exclude patients with tandem ICA/MCA occlusion from intravenous thrombolysis.
