Summary
Routine cerebral angiography is not recommended for patients with infective endocarditis. While intracranial mycotic aneurysms can occur, the risks associated with angiography outweigh the benefits for most patients.
Area of Science:
- Neurology
- Infectious Diseases
- Cardiology
Background:
- Infective endocarditis (IE) poses a risk of developing intracranial mycotic aneurysms (IMAs).
- The optimal management strategy for IMAs in IE patients remains uncertain.
Purpose of the Study:
- To evaluate the impact of cerebral angiography on survival outcomes in patients with IE.
- To determine if routine screening for IMAs via angiography is warranted in IE.
Main Methods:
- Literature review to estimate 12-week survival probability after IE diagnosis.
- Analysis of the specific mortality associated with IMAs and angiography.
Main Results:
- For a hypothetical 40-year-old female patient, 12-week survival was similar with (83.65%) and without (83.75%) angiography.
- Angiography slightly increased specific mortality from 0.25% to 0.35% due to associated risks.
- Aneurysm rupture risk and mortality are key factors influencing management decisions.
Conclusions:
- Routine cerebral angiography is not advised for all patients with infective endocarditis.
- Further research is needed to identify specific patient subgroups who might benefit from this diagnostic approach.
