Does intracranial dye study contribute to evaluation of carotid artery disease?

Area of Science:

• Neurology
• Vascular Imaging
• Radiology

Background:

• Cerebral arteriography is a key diagnostic tool for suspected carotid artery disease.
• Evaluating the intracranial circulation component is crucial for comprehensive assessment.

Purpose of the Study:

• To retrospectively assess the prevalence and significance of intracranial findings in patients undergoing cerebral arteriography for suspected carotid artery disease.
• To determine if intracranial evaluations alter clinical management in this patient cohort.

Main Methods:

• Retrospective review of 1000 consecutive cerebral arteriograms.
• Analysis focused on the intracranial circulation, including siphon stenosis and aneurysms.
• Correlation of findings with clinical management decisions.

Main Results:

• 784 patients (78%) had intracranial arteriograms.
• Siphon stenosis (5-70%) found in 6% (46 patients); no lesion >75%.
• Intracranial aneurysms in 2% (13 patients), all asymptomatic; 1 intracranial tumor identified.

Conclusions:

• Significant intracranial vascular disease or aneurysms were uncommon in this series.
• Intracranial findings from cerebral arteriography did not change management for these patients.
• Routine intracranial assessment during carotid disease workup may have limited impact on clinical decisions.
