Abstract:
Intravascular mechanical thrombectomy is the first-line treatment for acute ischemic stroke caused by large vessel occlusion. Parenchymal hyperdensities are common on CT scan after mechanical thrombectomy. At present, it is generally believed that it is caused by the increase of permeability after the destruction of blood-brain barrier. The appearance of parenchymal hyperdensities not only indicates a higher risk of hemorrhagic transformation, but also indicates the possibility of occurring infarction. The identification of parenchymal hyperdensities is very important for clinical decision-making and intervention, and dual-energy CT or MRI may have advantages in this regard. Further research is needed to clarify the characteristics and significance of parenchymal hyperdensities after endovascular mechanical thrombectomy.
