Insights
Mechanical thrombectomy may be a safe and effective treatment for acute ischemic strokes caused by infective endocarditis (IE). This procedure may reduce stroke severity, although further large-scale studies are needed.
Area of Science:
- Neurology
- Cardiology
- Interventional Radiology
Background:
- Infective endocarditis (IE) frequently leads to thromboembolic events, including acute ischemic strokes.
- Intravenous thrombolytics are often contraindicated in IE patients due to increased intracranial hemorrhage risk.
- Mechanical thrombectomy presents a potential alternative for large vessel occlusion (LVO) strokes in this population.
Purpose of the Study:
- To systematically review and meta-analyze the outcomes and safety of mechanical thrombectomy for LVO stroke patients with IE.
- To assess the efficacy and safety profile of mechanical thrombectomy in this specific patient group.
Main Methods:
- A systematic literature search was conducted across PubMed, Scopus, Web of Science, and Embase.
- Keywords included "infective endocarditis", "stroke", and "mechanical thrombectomy".
- Data from 6 studies involving 120 patients were pooled for analysis.
Main Results:
- Mechanical thrombectomy showed a potential reduction in NIH Stroke Scale (NIHSS) scores (WMD: -3.06; 95% CI: -4.43 to -1.70).
- The pooled rate of symptomatic intracranial hemorrhage was 15% (95% CI: 4-47%).
- The pooled rate of all-cause mortality was 34% (95% CI: 14-61%).
Conclusions:
- Mechanical thrombectomy appears to be an effective and reasonably safe treatment option for large vessel occlusion strokes secondary to infective endocarditis.
- Further large-scale research is warranted to confirm these findings and establish definitive treatment guidelines.
Abstract:
Thromboembolic events such as acute ischemic strokes are frequently seen in patients with infective endocarditis (IE). It is generally recommended that the administration of intravenous thrombolytics is avoided in these patients as they might encounter a higher risk of intracranial hemorrhages. In this setting, particularly with a large vessel occlusion (LVO), a mechanical thrombectomy may be an alternative option. In this systematic review and meta-analysis, we aimed to investigate the outcomes and safety of mechanical thrombectomies for LVO stroke patients secondary to IE. A search strategy was developed and we searched PubMed, Scopus, Web of Sciences, and Embase using the words "infective endocarditis", "stroke", and "mechanical thrombectomy". Including 6 studies and 120 patients overall, this study showed that a mechanical thrombectomy might reduce the National Institute of Health Stroke Scale (NIHSS), with a weighted mean difference of -3.06 and a 95% CI of -4.43 to -1.70. The pooled rate of symptomatic intracranial hemorrhages and all-cause mortality were also determined to be 15% (95% CI: 4-47%) and 34% (95% CI:14-61%), respectively. The results of this study showed that a mechanical thrombectomy might be an effective and reasonably safe option for the treatment of LVO strokes caused by IE. However, more large-scale studies are needed to consolidate these results.
