Stroke carries a severe toll in terms of loss of life and disability for patients and their families. Until 10 years ago, physicians, and in particular neurologists, had a conservative, nonaggresive approach to this devastating disease. The advent of thrombolytic therapy not only proved that acute ischemic stroke is treatable, but also that early reperfusion can dramatically change the outcome of acute stroke patients. As a result of these trials, intravenous (IV) tissue plasminogen activator (t-PA) has been approved for treatment of acute ischemic stroke within 3 hours after symptom onset in the United States, Canada, Australia, and the European Union. The near future is extremely promising. Imaging modalities, such as diffusion- and perfusion-weighted images, as well as CT perfusion and CT angiography, to better select patients for treatment are now routinely performed in most academic medical centers. Novel IV and intra-arterial (IA) agents have been developed and tested. Emerging therapies will soon be available to increase the therapeutic windows for thrombolysis both by better screening patients using MRI or CT and by new IV and IA treatments. Several multicenter controlled trials in both imaging-guided decisions and therapeutic agents are either completed or being performed. We review data on advancement in imaging and treatment of acute ischemic stroke, in particular focusing on pharmacologic and mechanical IA thrombolysis. |
