The Use of High-Risk Criteria in Screening Patients for Blunt Cerebrovascular Injury: A Survey

Experience and lessons learned from blunt cerebrovascular injuries: A case report

Background

Blunt cerebrovascular injuries are rare and serious complications of trauma that can lead to cerebral vascular dissection or aneurysm. Improving awareness of blunt cerebrovascular injuries and using computed tomography angiography to pre-screen patients at high risk is recommended by current guidelines to prevent the occurrence of ischemic stroke complications.

Case description

A 32-year-old male patient was admitted to the hospital following neck trauma accompanied by stroke symptoms. Imaging revealed intimal injury of the right common carotid artery and acute cerebral infarction. After an endarterectomy and repair, the vascular lumen obstruction resolved, blood flow was restored, and the patient's condition stabilized.

Conclusion

Blunt cerebrovascular injury has been seriously neglected in clinical practice. Delayed or under-diagnosis of blunt cerebrovascular injury can result large strokes. Standardized treatment protocols, which include the screening and grading of blunt cerebrovascular injury, may reduce the risk of permanent neurological dysfunction, and even death, in patients.

GPs' familiarity with and use of cardiovascular clinical prediction rules: a UK survey study

BACKGROUND

Clinical prediction rules (CPRs) can help general practitioners (GPs) address challenges in cardiovascular disease. A survey published in 2014 evaluated GPs' awareness and use of CPRs in the UK. However, many new CPRs have been published since and it is unknown which cardiovascular CPRs are currently recognised and used.

AIM

To identify cardiovascular CPRs recognised and used by GPs, and to assess how GPs' familiarity and use have changed over time.

DESIGN & SETTING

An online survey of GPs in the UK was undertaken.

METHOD

Using comparable methods to the 2014 survey, GPs were recruited from a network of doctors in the UK. They were asked how familiar they were with cardiovascular CPRs, how frequently they used them, and why they used them. The results were compared with the 2014 survey.

RESULTS

Most of 401 GPs were familiar with QRISK scores, ABCD scores, CHADS scores, HAS-BLED score, Wells scores for deep vein thrombosis, and Wells scores for pulmonary embolism. The proportions of GPs using these CPRs were 96.3%, 65.1%, 97.3%, 93.0%, 92.5%, and 82.0%, respectively. GPs' use increased by 31.2% for QRISK scores, by 13.5% for ABCD scores, by 54.6% for CHADS scores, by 33.2% for Wells scores for deep vein thrombosis, and by 43.6% for Wells scores for pulmonary embolism; and decreased by 45.9% for the Joint British Societies (JBS) risk calculator, by 38.7% for Framingham risk scores, and by 8.7% for New Zealand tables. GPs most commonly used cardiovascular CPRs to guide therapy and referral.

CONCLUSION

The study found GPs' familiarity and use of cardiovascular CPRs changed substantially. Integrating CPRs into guidelines and practice software might increase familiarity and use.

Blunt Cerebrovascular Injuries: Advances in Screening, Imaging, and Management Trends

Blunt cerebrovascular injury is a relatively uncommon but sometimes life-threatening injury, particularly in patients presenting with ischemic symptoms in that vascular territory. The decision to pursue vascular imaging (generally CT angiography) is based on clinical and imaging findings. Several grading scales or screening criteria have been developed to guide the decision to pursue vascular imaging, as well as to recommend different treatment options for various injuries. The data supporting many of these guidelines and options are limited however. The purpose of this article is to review and compare these scales and criteria and the data supporting clinical efficacy and to make recommendations for future research in this area.
