It has been appreciated over the past two decades that arterial remodelling, in addition to intimal hyperplasia, contributes significantly to the degree of restenosis that develops following revascularization procedures. Remodelling appears to be an adventitia-based process that is contributed to by multiple factors including cytokines and growth factors that regulate ...

Basilar artery thrombosis is associated with poor clinical outcomes and high mortality rate if untreated. Clinical outcome correlates with recanalization success. As arterial clot composition undergoes organization over time and may become more resistant to recanalization therapy, we postulate that recanalization success is time-dependent. We aim to investigate whether time ...
