Thank you for your first fruitful comment. Even though the study is retrospective in nature, the authors have presented a good idea in guiding of stroke treatment. The limitation of age should be considered in any aggressive treatment. Specifically in endovascular stroke business where treatment of this degenerative process might not be easily satisfied for patient and relatives in term of quality of life. Discreet case selection is still mandatory in our daily practice. However, with improvement in endovascular materials and techniques, we might be able to defeat this limitation soon.
