Insights
This case report details infectious endocarditis (IE) with cerebral infarction and mycotic aneurysm rupture. Surgical timing between cranial and cardiac procedures is crucial for preventing neurological complications.
Area of Science:
- Cardiology
- Neurosurgery
- Infectious Diseases
Background:
- Infectious endocarditis (IE) poses significant risks, including embolic events and neurological complications.
- Mycotic intracranial aneurysms are a rare but severe manifestation of IE.
- Cerebral infarction and aneurysm rupture present complex management challenges in IE patients.
Observation:
- A 66-year-old male with Streptococcus sanguis IE presented with prior cerebral infarction.
- Echocardiography revealed large vegetations on aortic and mitral valves.
- MRI confirmed subarachnoid hemorrhage from a ruptured intracranial aneurysm, requiring surgical intervention.
Findings:
- Bacteriological analysis of the resected aneurysm identified Streptococcus sanguis.
- Aortic and mitral valve replacement was successfully performed 11 days post-neurosurgery.
- No new neurological deficits were observed postoperatively.
Implications:
- This case highlights the critical importance of the interval between cranial and cardiac surgery in managing IE with neurological complications.
- Optimizing surgical sequencing may mitigate risks of secondary neurological events.
- Multidisciplinary management is essential for complex IE cases involving cerebrovascular complications.
Abstract:
A surgically treated case of infectious endocarditis (IE) complicated with preoperative cerebral infarction and rupture of mycotic intracranial aneurysm was reported. A 66-year-old male was admitted with the diagnosis of active IE due to Streptococcus sanguis, complicated with cerebral infarction 17 days previously. Preoperative echocardiography showed mobile vegetations both on the aortic and the mitral leaflet, sizes of which were 12.6 and 25 mm. The magnetic resonance imaging (MRI) demonstrated a subarachnoid homorrhage due to the rupture of an intracranial aneurysm, and was treated surgically. The bacteriological study of the resected aneurysm showed Streptococcus sanguis. Eleven days after the operation, both the aortic and the mitral valve replacement were performed. There were mobile vegetations on the aortic and the mitral leaflet. There were no new neurological findings after operation. The duration between the cranial surgery and the cardiac surgery was thought to be important to prevent the new neurological complication.
