CONCLUSION

This study shows the histological composition of thrombus might lead to the different clinical characteristics, especially the response to IVT. The RBC dominance can be an important factor affecting the response to IVT comparable with clinical or radiological findings in this study. These findings might affect clinical outcome through increased symptomatic hemorrhage related with increased RBC ratio. The response to IVT appears to be influenced by histopathological features of retrieved thrombi and clinical implication will be further evaluated.
