1Division of Cardiovascular Surgery, Nagoya City University Medical School, Nagoya, Japan.
Insights
A rare case of aortic dissection coexisting with an aneurysm was managed, initially conservatively, then surgically. This highlights the complex relationship and risks associated with these aortic conditions.
Area of Science:
- Cardiovascular Medicine
- Thoracic Surgery
- Vascular Surgery
Background:
- Stanford type A aortic dissection presents unique management challenges.
- Atherosclerotic aneurysms in the aortic arch increase rupture risk.
- The interplay between aortic dissection and aneurysm requires careful consideration.
Observation:
- A 76-year-old male presented with Stanford type A bidirectional closing aortic dissection and a distal arch aneurysm.
- Initial conservative management with pericardial drainage was employed due to cardiac tamponade.
- Aneurysm expansion and recurrent dissection in the descending aorta were noted two months post-onset.
Findings:
- Surgical repair was successfully performed after initial conservative management.
- The coexistence of dissection and aneurysm poses a significant risk of aortic rupture.
- The management of closing aortic dissections remains debated due to limited understanding.
Implications:
- This case underscores the importance of vigilant monitoring for patients with combined aortic dissection and aneurysm.
- Effective surgical planning is crucial for managing complex aortic pathologies.
- Further research into the pathogenesis and optimal management strategies for closing aortic dissections is warranted.
Abstract:
We experienced one rare case of a 76-year-old male with a Stanford type A bidirectional closing aortic dissection from a coexisting atherosclerotic distal arch aneurysm. He showed a cardiac tamponade, and effective pericardial drainage allowed us to conservatively manage the patient. Both an increase in the size of the aneurysm and a recrudescent dissection in the descending aorta were identified 2 months after the onset. A scheduled surgical repair was successful. The coexistence of an acute aortic dissection and an atherosclerotic aneurysm increases the risk of an aortic rupture, particularly at the confluence of the two lesions. Meanwhile, the management of a closing aortic dissection remains controversial because its characteristics still are not well known. We studied not only the pathogenesis but also the management of these two forms of aortic disease and their complex relationships.
