Objective: Flat detector computed tomography perfusion (FD-CTP) imaging is a new modality that enables quick assessment of the cerebral perfusion in the angiography suite. We present three cases in which FD-CTP served to improve the precision of the therapeutic strategy during endovascular treatment.
Case presentation: The first case was a 40-year-old woman with a ruptured blood blister-like aneurysm in the right internal carotid artery (ICA). After the evaluation for tolerance to ICA occlusion using FD-CTP, she was treated successfully with endovascular internal trapping of the ICA.
The second case was an 89-year-man with a cerebral infarct in the left cerebrum due to severe stenosis of the left middle cerebral artery. After the angioplasty, we could confirm the therapeutic effect by using FD-CTP, which demonstrated the disappearance of hypoperfusion in the left cerebral hemisphere. The third case was an 88-year-old man with severe stenosis of the left cervical carotid artery. After dilatation of the stenotic lesion by using a small-diameter balloon, a FD-CTP image showed hyperemia in the left cerebral hemisphere, so we decided not to undergo further carotid artery stenting.
Conclusion: FD-CTP was useful for determining the therapeutic strategy during endovascular treatment.
