Is a cerebral infarction the same as a stroke?

A cerebral infarction (also known as a stroke) refers to damage to tissues in the brain due to a loss of oxygen to the area. The mention of "arteriosclerotic cerebrovascular disease" refers to arteriosclerosis, or "hardening of the arteries" that supply oxygen-containing blood to the brain.

What is transient hypotension?

Transient hypotension. Clinical Information. A disorder characterized by a blood pressure that is below the normal expected for an individual in a given environment. Abnormally low blood pressure that can result in inadequate blood flow to the brain and other vital organs.

What is cerebral perfusion?

Computed tomography (CT) perfusion imaging provides a quantitative measurement of regional cerebral blood flow. Cerebral perfusion analysis is used in neuroradiology to assess tissue level perfusion and delivery of blood to the brain and/or tissues of the head. A perfusion CT study involves sequential acquisition of CT sections during intravenous administration of an iodinated contrast agent. The procedure involves injecting a contrast agent into the individual. The blood carries the contrast agent to the brain and the rate at which it accumulates in the brain is detected by a CT scanner. Analysis of the results allows the physician to calculate the regional cerebral blood volume, the blood mean transit time through the cerebral capillaries, and the regional cerebral blood flow.

Why is cerebral CT perfusion considered experimental?

Aetna considers cerebral CT perfusion studies experimental and investigational for the following indications because there is inadequate scientific evidence to support its use for these indications (not an all-inclusive list): Confirmation of brain death. Differentiation of lung cancer from benign lesions.

What is CTP in TBI?

Bendinelli and colleagues (2017) noted that in patients with severe TBI, early CTP provides additional information beyond the NCCT and may alter clinical management. These researchers hypothesized that this information may prognosticate functional outcome. They carried out a 5-year prospective observational study in a level-1 trauma center on consecutive severe TBI patients; CTP (obtained in conjunction with first routine NCCT) was interpreted as: abnormal, area of altered perfusion more extensive than on NCCT, and the presence of ischemia; 6 months Glasgow Outcome Scale-Extended of 4 or less was considered an unfavorable outcome. Logistic regression analysis of CTP findings and core variables (pre-intubation Glasgow Coma Scale (GCS), Rotterdam score, base deficit, age) was conducted using Bayesian model averaging to identify the best predicting model for unfavorable outcome. A total of 50 patients were investigated with CTP (1 excluded for the absence of TBI) [men: 80 %, median age of 35 (23 to 55), pre-hospital intubation: 7 (14.2 %); median GCS = 5 (3 to 7); median injury severity score = 29 (20 to 36); median head and neck abbreviated injury scale = 4 (4 to 5); median days in ICU = 10 (5 to 15)]; 30 (50.8 %) patients had an unfavorable outcome; GCS was a moderate predictor of unfavorable outcome (area under the curve [AUC] = 0.74), while CTP variables showed greater predictive ability (AUC for abnormal CTP = 0.92; AUC for area of altered perfusion more extensive than NCCT = 0.83; AUC for the presence of ischemia = 0.81). The authors concluded that following severe TBI, CTP performed at the time of the 1st follow-up NCCT, is a non-invasive and extremely valuable tool for early outcome prediction. These investigators stated that the potential impact on management and its cost-effectiveness deserves to be evaluated in large-scale studies. Level of Evidence = III:

What are the limitations of a 64-slice CT scan?

The authors stated that the main limitation of this study was the restricted slice number during acquisition of perfusion images as only 4 cm of tissue of interest could be imaged with the 64-slice CT scanner. Thus, the whole tumor volume could not be imaged in full. In addition, the limited region of interest might have been “non-representative” of whole tumor perfusion, especially in large and heterogeneous lesions. Finally, a relatively small sample size for each of the conditions was another drawback of the study.

Is CT perfusion imaging feasible?

Current literature on CT perfusion imaging has focused on its feasibility and technical capabilities. Prospective clinical studies are needed to determine the clinical value of CT perfusion imaging over standard non-contrast computed tomography in the assessment of patients with symptoms suggestive of acute stroke, and in the triage of patients in whom thrombolytic therapy is contemplated.

Can hemorrhagic transformation be predicted?

Horsch et al (2018) stated that hemorrhagic transformation (HT) in acute ischemic stroke (AIS) can occur as a result of re-perfusion treatment. While withholding treatment may be warranted in patients with increased risk of HT, prediction of HT remains difficult. Non-linear regression analysis can be used to estimate blood-brain barrier permeability (BBBP). These researchers identified a combination of clinical and imaging variables, including BBBP estimations, that could predict HT. From the Dutch acute stroke study, 545 patients treated with intravenous (IV) recombinant tissue plasminogen activator (rtPA) and/or intra-arterial treatment were selected, with available admission extended CT perfusion and follow-up imaging. Patient admission treatment characteristics and CT imaging parameters regarding occlusion site, stroke severity, and BBBP were recorded. HT was assessed on day 3 follow-up imaging. The association between potential predictors and HT was analyzed using uni-variate and multi-variate logistic regression. To compare the added value of BBBP, AUCs were created from 2 models, with and without BBBP. HT occurred in 57 patients (10 %). In uni-variate analysis, older age (OR 1.03, 95 % CI 1.006-1.05), higher admission NIHSS (OR 1.13, 95 % CI: 1.08 to 1.18), higher clot burden (OR 1.28, 95 % CI: 1.16 to 1.41), poor collateral score (OR 3.49, 95 % CI: 1.85 to 6.58), larger Alberta Stroke Program Early CT Score cerebral blood volume deficit size (OR 1.26, 95 % CI: 1.14 to 1.38), and increased BBBP (OR 2.22, 95 % CI: 1.46 to 3.37) were associated with HT. In multi-variate analysis with age and admission NIHSS, the addition of BBBP did not improve the AUC compared to both independent predictors alone (AUC 0.77, 95 % CI: 0.71 to 0.83). The authors concluded that CT perfusion-derived BBBP predicted HT; however, it did not improve prediction with age and admission NIHSS. These investigators stated that the technique of BBBP measurements needs further improvement before it can be a useful addition to decision-making in patients considered for IV-rtPA treatment.

Can CT perfusion be used for ischemia?

Furthermore, no recommendation can be made for the use of CT perfusion in patients with chronic ischemia, vasospasm, head trauma, or as part of the balloon occlusion test, the traditional method for identifying patients at risk for stroke.

Abstract

Use of phosphodiesterase-5 (PDE-5) inhibitors has been reported to be a risk factor for development of nonarteritic anterior ischemic optic neuropathy (NAION) in males, based largely on a number of case reports.

METHODS

We used the IMS Lifelink database as the data source for this study. Lifelink is a health claims database that captures prescription drug dispensing, physician visits, hospitalizations, and demographic information for approximately 68 million residents of the United States.

RESULTS

Within the initial cohort of 934,283 individuals, a total of 1,109 cases of NAION diagnosis were found and matched to 1,237,290 age-matched controls.

DISCUSSION

The results of this large retrospective case–control study support the lack of association between NAION and PDE-5 inhibitor use.
