Abstract Background Thrombolysis with tissue-type plasminogen activator (IV-tPA) is a well-proved, widely used treatment in acute ischemic stroke patients, many predictors of functional outcome have been proposed as Age, vascular risk factors, initial clinical evaluation on admission using National institute of health stroke scale(NIHSS), functional state of patient(b.L) baseline before stroke and 3 months (3m) after stroke using modified Rankin stroke scale (MRS)and the most controversial Diffusion weighted image characteristics (volume, heterogeneity) Objective To evaluate DWI MRI characteristics (volume, heterogeneity) as a predictor for outcome in Acute stroke patients treated by IV-tPA Patients and Methods This study will be done on a sample of 100 acute ischemic stroke Egyptian patients receiving intra-venous tissue -type plasminogen activator presenting to Ain-Shams university hospitals Results Highly statistically significant (p-value < 0.001) Positive correlation (r = 0.394) between volume (DWI) and MRS (3m) post discharge in studied patients, No statistically significant (pvalue > 0.05) relation between heterogeneity and other studied parameters (MRS, NIHSS D & ADC values) in studied patients Conclusion DWI infarct volume is a predictor for outcome in acute ischemic stroke patients treated by tPA

Background: Intravenous recombinant tissue-type plasminogen activator (rt-PA) administration improves outcomes in acute ischemic stroke. However, young patients (<40 years old) presenting with stroke symptoms may experience delays in treatment due to misdiagnosis or a reluctance to treat since they do not fit the profile of a typical stroke patient. Methods: We analyzed data from the large national Get With The Guidelines–Stroke registry for acute ischemic stroke patients hospitalized between January 2009 and September 2015. Multivariable models with generalized estimating equations (GEE) were used to test for differences between younger (age 18-40) and older (age > 40) acute ischemic stroke patients, controlling for patient and hospital characteristics including stroke severity. Results: Of 1,320,965 AIS patients admitted to participating hospitals, 2.3% (30,448) were aged 18-40. Among these patients, 12.5% received rt-PA versus 8.8% of those aged >40 (p<0.001). Of patients arriving within 3.5 hours of symptom onset without contraindications, 68.7% of younger patients received IV rt-PA versus 63.3% of older patients (adjusted OR [aOR] 1.30, 95% CI 1.21 to 1.40), without evidence that age-related differences varied by sex (interaction p-value 0.25). Odds ratios of achieving target door-to-CT times and door-to-needle (DTN) times, and outcomes of rtPA-treated patients, are shown in the Table. Conclusions: Young acute ischemic stroke patients did not receive rt-PA treatment at lower rates than older patients. Outcomes were better and the rate of symptomatic intracranial hemorrhage was lower in the young patients. However, younger patients had significantly longer door-to-CT and DTN times, providing an opportunity to improve the care of these patients.

Promising Treatment

Acute ischemic stroke is now considered a neurological emergency for which there are new therapies. Neurosurgeons and neurologists need to remain apprised of advances in this field. The authors discuss approved and emerging therapies for patients suffering from acute ischemic stroke, based on a review of recent publications. Currently, intravenous tissue-type plasminogen activator is the only Food and Drug Administration–approved therapy for acute ischemic stroke. Intraarterial delivery of thrombolytics is a promising treatment and may be effective in selected patients. Other therapies for acute cerebral ischemia are intriguing but still in the investigational stages.
