Clinical Report: Spontaneous Rupture of an Internal Thoracic Artery Aneurysm
Overview
This report details a rare case of a ruptured internal thoracic artery (ITA) pseudoaneurysm in a 42-year-old female, highlighting the critical need for rapid diagnosis and intervention. Emergency computed tomography angiography (CTA) confirmed the diagnosis, leading to successful endovascular treatment and patient recovery.
Background
Internal thoracic artery aneurysms are rare vascular anomalies that often remain asymptomatic until they rupture, leading to life-threatening conditions such as acute hemothorax and hemorrhagic shock. The challenge in diagnosis is compounded by the non-specific nature of symptoms, necessitating a high index of suspicion among emergency physicians. Advances in imaging and endovascular techniques have improved outcomes for these patients.
Data Highlights
No numerical data or trial data available in the article.
Key Findings
['Ruptured ITA aneurysms can present with symptoms mimicking pleural effusion, complicating diagnosis.', 'Emergency CTA is crucial for identifying ruptured aneurysms and associated complications.', 'Endovascular transcatheter arterial embolization (TAE) is an effective first-line treatment for hemodynamically unstable patients.', 'Fewer than 50 cases of ITA aneurysms have been reported globally, indicating their rarity.', 'Prompt recognition and intervention are essential to prevent fatal outcomes.']
Clinical Implications
Healthcare professionals should maintain a high index of suspicion for ITA aneurysms in patients presenting with unexplained chest or abdominal pain and hemothorax. Emergency CTA should be utilized for rapid diagnosis, and endovascular techniques should be considered as a primary treatment option in appropriate cases.
Conclusion
This case underscores the importance of recognizing the potential for ITA aneurysms in emergency settings and the effectiveness of endovascular treatment in managing this critical condition.
