Perfusion tomography in early follow-up of acute traumatic subdural hematoma: a case series
Authors' conclusion
CBF seems to increase after surgery, especially when evaluated together with the MTT values.
Study context
- Population
- Adults with moderate and severe traumatic brain injury (TBI) and acute traumatic subdural hematoma indicated for surgical evacuation
- Participants
- 5 adults
- Exposure
- Preoperative vs postoperative cerebral hemodynamics on Perfusion Computed Tomography (PCT)
- Outcome
- Cerebral hemodynamics (CBF, CBV, mean transit time (MTT)) on perfusion CT before and after surgery
Main finding
As reported in the abstract
CBF
P = 0.06
Observational data: associations, not effects.
Further findings
MTT · not statistically significant
P = 0.06
Cerebral blood volume (CBV)
- CBV increased after surgery, from 2.34 (SD: 0.67) to 2.63 ml/100 g (SD: 1.10)
- P = 0.31
Correlation of postoperative/preoperative cerebral blood flow (CBF) ratio with outcome at 6 months (Spearman)
- Spearman correlation
- 0.94
- p = 0.054
