Summary
This case study highlights a rare instance of De Bakey type III aortic dissection, a condition involving the descending aorta. Early diagnosis through advanced imaging was crucial for managing this complex aortic anomaly.
Area of Science:
- Cardiovascular Medicine
- Diagnostic Imaging
- Anatomical Variations
Background:
- Aortic dissection is a serious condition involving a tear in the aorta's inner layer.
- Congenital anatomical variations of the aortic arch can predispose individuals to aortic pathologies.
- De Bakey type III dissection involves the descending aorta and can present with diverse symptoms.
Observation:
- A 51-year-old woman presented with acute chest and back pain, dyspnea, and signs of shock.
- Initial imaging revealed an absent left aortic arch and right lung hypopneumatization.
- Subsequent CT scans demonstrated a right-sided aortic arch with a false lumen and dextrosinistral crossing of the abdominal aorta.
Findings:
- The patient was diagnosed with De Bakey type III aortic dissection, characterized by a right aortic arch and dissociation from the arch to the abdominal aorta.
- Associated findings included a dissociant aneurysm of the right aortic arch and tapering of the abdominal aorta.
- Clinical presentation included disseminated intravascular coagulation (DIC) and multiorgan disorders.
Implications:
- This case underscores the importance of advanced imaging techniques like CT angiography in diagnosing rare aortic anomalies.
- Recognition of atypical aortic arch anatomy is critical for accurate diagnosis and management of aortic dissections.
- Prompt medical management can lead to an uneventful clinical course despite severe initial presentation.
