Clinical Management of Acute Stroke

Further animal studies showed the agent to be also selectively retained in acutely ischemic brain, but not in the ischemic infarct. It is therefore a marker of ischemic tissue at risk of infarction and may contribute to the clinical management of acute stroke [221]. In addition, BMS-181321 was recently reported to be taken up in solid mice tumors with a tumor-to-musclc activity ratio of 3.5-4.0 at 4-8 h after injcc-...

The use of full-dose unfractionated heparin in the management of acute ischemic stroke remains controversial despite years of debate and a lack of evidence supporting its use. Proponents of the therapy cite strong anecdotal evidence of positive responses in selected patients who have never been studied in clinical trials. 

Although MRI is promising in that it provides specific information which could improve treatment in ischemic stroke, there is no scientific proof that it actually does improve patients clinical outcome. Consequently, based on current knowledge, the recommendation to base acute stroke management solely on MRI means a big investment without a guaranteed return in the form of reduced health care costs. 

The earlyidentification ofthe clinical andMR patterns of acute territorial infarcts can help the managing physician concerning prediction of outcome, risk of early death and dependency, risk of recurrence, stroke mechanism and etiology, selection of ancillary procedures, selection of best (effective and safe) anti-thrombotic treatment, risk of complications, length of stay and cost of hospital care.

Some of the clinical consequences in SS disease include megaloblastic erythropoiesis, aplastic crisis, stroke, bone pain crisis, proneness to infection particularly by Pneumococcus, Salmonella, and Haemophilus due to hypos-plenism and acute chest syndrome. Prophylactic use of penicillin and antipneumococcal and Haemophilus vaccines has aided in the management of life-threatening infectious complications of SS disease. Neonatal screening has been used in the identification of infants with sickle cell disease so that risk of infection can be modulated by appropriate immunizations and penicillin prophylaxis. The acute chest syndrome characterized by chest pain is due to clogged pulmonary capillaries in a small number of studies, patients have been treated with inhaled nitric oxide, which dilates blood vessels with clinical improvement.

The concept of the ischemic penumbra has proven to be an extremely valuable construct for both experimental studies of ischemic stroke and for the development of tools for the management of patients with this disorder. Indeed, a major driver in the development of treatments for ischemic stroke is the belief that in many acute stroke patients, there is a region of salvageable brain that is threatened with permanent injury. This region of brain corresponds to the ischemic penumbra originally described in experimental stroke studies. The clinical condition does not strictly meet the criteria as originally defined by experimentalists. Nonetheless, the concept is clinically valuable, and a suitable modification of its definition applicable to the clinical condition is appropriate. 

Medical evaluation of the patient presenting with acute stroke is important because patients with cerebrovascular disease frequently have other forms of cardiovascular or other systemic disease, which may complicate medical management. If the patient is undergoing thrombolysis, bleeding from sites of systemic illness may become clinically evident. For this reason, medical teams should perform a stepwise analysis of the patient s organ systems, giving special consideration to the conditions listed in Table 10.3.
