Conclusion
From literature we already know that:
- CT perfusion is useful in the selection of patients who have to undergo endovenous thrombolysis before and after 4.5 hours [1,2]
- CT perfusion has a higher sensitivity,
compared to unenhanced CT and CT angiography[3]
- CT perfusion strenghtens the findings of unenhanced CT for the selection of patients suitable for thrombolysis [4,5]
- A selection of patients to treat with the data obtained with CT perfusion could bring benefits and a reduction of costs [6].
Our study confirms what is already known from the literature and underlines that CT perfusion has an important role in the exclusion of patients not suitable for thrombolytic treatment,
such as those with a high core volume and poor penumbra and those with symptoms due to other causes (such as migraines or seizures),
in order to avoid unnecessary treatments and potentially harmful for the patients.
