Progression of carotid near-occlusion to complete occlusion: related factors and clinical implications.

Background: The clinical consequences and factors related to the progression from a carotid near-occlusion (CNO) to a complete occlusion are not well established. Our aim is to describe the rate, predictive factors and clinical implications of the progression to complete carotid occlusion (PCCO) in a population of patients with symptomatic CNO.

Methods: We conducted a multicenter, nationwide, prospective study from January 2010 to May 2016.

Early risk of recurrent stroke in patients with symptomatic carotid near-occlusion: Results from CAOS, a multicenter registry study.

Background The risk of recurrent stroke among patients with symptomatic carotid near-occlusion is not well established, and management of the condition remains controversial. Symptomatic carotid near-occlusion with full collapse has been identified as a strong predictor of early recurrence. We aimed to analyze the 90-day risk of recurrent ipsilateral ischemic stroke in medically treated patients with symptomatic carotid near-occlusion.

Intra-arterial bone marrow mononuclear cells (BM-MNCs) transplantation in acute ischemic stroke (IBIS trial): protocol of a phase II, randomized, dose-finding, controlled multicenter trial.

Rationale: No neuroprotective or neurorestorative therapies have been approved for ischemic stroke. Bone marrow mononuclear cell intra-arterial transplantation improves recovery in experimental models of ischemic stroke.

Aims: This trial aims to test safety and efficacy of intra-arterial injection of autologous bone marrow mononuclear cell in ischemic stroke patients.
