Common carotid artery occlusion: a case series

Area of Science:

• Vascular Surgery
• Neurology
• Radiology

Background:

• Common carotid artery occlusion (CCAO) is a rare condition.
• Understanding its risk factors, presentation, and outcomes is crucial for patient management.

Purpose of the Study:

• To analyze the characteristics, risk factors, and outcomes of patients with common carotid artery occlusion.
• To evaluate the role of atherosclerosis as the primary etiology and the impact of distal vessel patency.

Main Methods:

• Retrospective analysis of 5000 cerebrovascular ultrasound records.
• Identification and characterization of patients diagnosed with common carotid artery occlusion (CCAO).

Main Results:

• CCAO was found in 0.4% of patients, with atherosclerosis being the most frequent cause.
• Hypertension, ischemic heart disease, dyslipidemia, diabetes, and smoking were common risk factors.
• Patent distal vessels were associated with improved outcomes, and spontaneous recanalization occurred in one case.

Conclusions:

• Atherosclerosis is the leading cause of CCAO.
• Patent distal vessels positively influence patient outcomes.
• Treatment strategies, including surgical revascularization, require further standardization and investigation.
