Gliederung

Text

Objective: There is still controversial discussion of the value of perfusion computed tomography (CTP) in predicting vasospasms in patients with aneurysmal SAH (aSAH). The present study was conducted to evaluate changes of CTP values in patients with intraarterial spasmolytic therapy (angiographically) before and after the intervention.

Methods: Retrospective analysis of, CTP and angiographies of N=141 patients treated from 2013-2015. In N=59 patients intra-arterial spasmolysis had been performed and in these cases CTP data were compared before and after lysis.

Results: After i.a. spasmolysis in patients with vasospasms the MTT showed significant improvement indicating to a significant correlation of blood flow in angiography and CT-perfusion. Surprisingly, there was no correlation between the known thresholds of mean transit time (MTT) in CTP and vasospasm.

Conclusion: Even when CTP did not identify vasospasms by changes of the MTT in order to establish a definitive pathological cut off value the MTT after angiographically lysis of spastic vessels was significantly lower compared to the values before lysis. CTP can not identify vasospasm but correlates to a response of spasmolytic therapy.
