Summary
This study reports two aortic arch aneurysm cases treated with grafts during profound hypothermia and circulatory arrest. Barbiturates and lidocaine effectively protected the brain, ensuring good neurological outcomes.
Area of Science:
- Cardiovascular Surgery
- Neurosurgery
- Anesthesiology
Background:
- Aortic arch aneurysms pose significant surgical challenges.
- Cerebral protection during aortic arch surgery is critical.
Purpose of the Study:
- To report two cases of aortic arch aneurysm repair.
- To evaluate the efficacy of profound hypothermia, circulatory arrest, barbiturates, and lidocaine for cerebral protection.
Main Methods:
- Surgical resection and Dacron graft replacement for aortic arch aneurysms.
- Utilization of profound hypothermia and temporary circulatory arrest.
- Administration of barbiturates and lidocaine for cerebral protection.
Main Results:
- One patient experienced an uneventful recovery with no evidence of cerebral ischemic damage.
- The second patient died postoperatively due to unrelated hepatic failure.
- Neurological function and cerebral structures remained intact in both cases.
Conclusions:
- Profound hypothermia combined with barbiturates and lidocaine provides adequate cerebral protection during aortic arch replacement.
- This neuroprotective strategy is effective for complex aortic arch surgeries.
