Traumatic carotid dissection is a well-known cause of ischemic stroke and although the treatment of the dissection itself has received some attention in recent years, the treatment of the concomitant stroke has been less investigated. We present a 43-year-old patient with blunt traumatic internal carotid artery dissection associated with subocclusive stenosis and major cerebral thromboembolic complication. ⋯ Contralateral carotid artery approach allowed the beginning of intra-arterial thrombolysis without delay, while stent-assisted angioplasty of the injured carotid was simultaneously performed. This approach was proved to be safe and effective and may deserve further evaluation.

Cerebral ischemia increases neurogenesis in the subventricular zone (SVZ) and in the subgranular zone (SGZ) of the dentate gyrus, and this might be modulated by an enriched environment including voluntary physical activity. We examined whether enforced physical training (EPT) influences neurogenesis in the SVZ and SGZ after cerebral ischemia. ⋯ The results obtained indicate that EPT promotes neurogenesis in the SGZ of the dentate gyrus after ischemia, but not in the SVZ. The biochemical mechanism that determines the differential effects of EPT remains to be clarified.
