Clinical Characteristics of Type A Aortic Dissection with Neurological Symptoms
Overview
This report details the clinical characteristics and outcomes of 23 patients with type A aortic dissection (TAAD) who presented with neurological symptoms. The findings highlight the risk of misdiagnosis and inappropriate treatment, emphasizing the need for increased awareness among healthcare professionals.
Background
Type A aortic dissection (TAAD) is a critical condition that can present atypically, often mimicking neurological disorders. Misdiagnosis can lead to significant delays in treatment, increasing mortality rates. Understanding the clinical features associated with TAAD is essential for timely diagnosis and management.

Key Findings
65.2% of patients presented with altered consciousness.
56.5% exhibited limb weakness, with a notable incidence of left-sided weakness.
Only 21.7% reported chest or back pain, complicating diagnosis.
39.1% received intravenous thrombolysis prior to TAAD diagnosis.
The overall in-hospital mortality rate was 65.2%.
Long-term survival rate post-discharge was 17.4%.
Clinical Implications
Healthcare professionals should maintain a high index of suspicion for TAAD in patients presenting with neurological symptoms, especially when typical chest pain is absent. Early identification and appropriate imaging can significantly improve outcomes.
Conclusion
The study underscores the importance of recognizing atypical presentations of TAAD to prevent misdiagnosis and improve patient management. Enhanced awareness among neurologists and emergency physicians is crucial.
