Stroke volume is the volume of blood pumped out of the left ventricle of the heart during each systolic cardiac contraction. The s troke volume is not all the blood contained in the left ventricle; normally, only about two-thirds of the blood in the ventricle is expelled with each beat. The normal range is 50 to 100 ml.

• Core infarct may not show up if there is later recruitment of collateral vessels from ACA and PCA (“futile leptomeningeal perfusion”) • If imaging patients very early (within an hour) after stroke, the volume of core infarct may be substantially overcalled at a CBF <30% threshold. Within an hour of stroke, a CBF <20%

However, the size of the infarction volume was larger in semiquantitative DWI stroke volume than in infarct core volume. The cut-off value for the futile outcomes was 85 cm 3 for infarct core volume with an ADC threshold of 600 × 10 –6 mm 2 /s whereas it was 150 cm 3 for semiquantitative DWI stroke volume in our results.

This may have clinical and therapeutic implications. Volume of infarct did not contribute to predicting error rate in either naming or comprehension, independently of volume of hypoperfusion, because in acute stroke the volume of hypoperfusion (when available) is a better marker of dysfunctional tissue than volume of infarct.

The significant association between early change in DWI infarct volume after stroke and functional outcome support the conclusion that the likelihood of achieving an excellent outcome diminishes substantially with growth in DWI lesion volume (>10 cm 3) in the first 5 days after stroke of mild to moderate severity. If these results are

RESULTS: A smaller than median infarct volume following ischemic stroke was associated with the interaction of statin pretreatment and positive diabetes status. This association remained significant (p = 0.01) in multivariable analysis even after controlling for factors related to demographics, comorbidities and risk factors, clinical features on admission, use of other medications and stroke 2011-06-17 Cerebral infarction volume was measured from brain computed tomography in the subacute phase (>2 days). Stroke aetiology was defined by trial of ORG 10172 in acute stroke treatment classification, severity by National Institute of Health stroke scale (NIHSS) and the degree of disability by the Modified Rankin Scale (mRS) after 90 days. 2018-06-22 Infarct volumes were measured using computerized tomography, 48-72 h after hospitalization. Results: Mean serum and CSF orexin-A concentrations were significantly lower among ischaemic stroke patients (n = 29) compared with control subjects (n = 13). 2013-11-01 2020-10-01 The odds of functional independence were independently reduced with greater post-EVT white matter infarct volume (OR, 0.89; 95% CI, 0.81–0.96; P=0.005) in a multivariable model controlling for infarct volumes in other regions, age, stroke severity and successful reperfusion. 2012-07-31 2013-07-23 2015-08-01 Background and Purpose: Larger infarct volume as a percent of supratentorial brain volume (SBV) predicts poor outcome and hemorrhagic transformation in childhood arterial ischemic stroke (AIS).

However, there are controversies around the infarct volume threshold that would allow to make the best prognosis estimation.

Most widely used in this setting is diffusion-weighted MRI (DWI), which has 2019-05-29 · Cerebral infarct volume measurement The Cerebral Infarct Volume (CIV) of all recanalized patients were manually delineated by one experienced neurologist (N.G.) on early follow-up brain CT scan (at 2–4 days after stroke). The infarct volume was delineated section-by-section by using ITK-SNAP 2.2.0 (http://www.itksnap.org/pmwiki/pmwiki.php).

Methods—Infarct volume and total intracranial volume were measured with Leica Q500 MCP image analysis software, or with a caliper, on 38 CT scans of patients who participated in the Tirilazad Efficacy Stroke Study II (TESS II). The scans were performed 8 days (±2 days) after the onset of symptoms. There is a limited correlation between the infarct volume and the severity of stroke symptoms; while the infarct volume accounts for 38% of the variation in stroke severity, the combination of both infarct volume and location can account for 62% of the variation in NIHSS scores. 8 Thus, there has been recent effort to assess the relationship Infarct volume can serve as a surrogate of clinical outcome in stroke trials. 10 Meaningful assessment of final infarct volume must therefore be made after a time sufficiently advanced through the course of lesion evolution to remove the confounding effects of edema.
