Delay in the diagnosis of cerebral vein and dural sinus thrombosis: influence on outcome
Related Experiment Videos
Insights
Delayed diagnosis of cerebral vein and dural sinus thrombosis (CVST) significantly increases the risk of visual deficits. For patients with isolated intracranial hypertension syndrome, diagnostic delay also correlates with increased mortality or dependency.
Area of Science:
- Neurology
- Vascular Neurology
- Diagnostic Imaging
Background:
- Cerebral vein and dural sinus thrombosis (CVST) diagnosis delays can negatively impact patient outcomes.
- The International Study on Cerebral Vein and Dural Sinus Thrombosis (ISCVT) investigated predictors and consequences of diagnostic delays in 624 patients.
Discussion:
- While overall outcomes (modified Rankin Scale, death) showed no significant difference based on median diagnostic delay, persistent visual deficits were more frequent in delayed diagnosis groups.
- Patients presenting with specific neurological signs like altered consciousness, seizures, or parenchymal lesions on imaging were diagnosed earlier.
- Conversely, male patients and those with isolated intracranial hypertension syndrome experienced diagnostic delays.
Key Insights:
- Diagnostic delay in CVST is considerable, with a median of 7 days.
- Delayed diagnosis is linked to a higher incidence of persistent visual deficits.
- In cases of isolated intracranial hypertension syndrome, delayed diagnosis is associated with worse outcomes, including death or dependency.
Outlook:
- Further research should focus on strategies to expedite CVST diagnosis, particularly in high-risk patient groups.
- Improved diagnostic protocols may mitigate the risk of visual deficits and improve functional outcomes in CVST patients.
- Understanding predictors of diagnostic delay is crucial for developing targeted interventions.
Background And Purpose:
Diagnostic delay of cerebral vein and dural sinus thrombosis may have an impact on outcome.
Methods:
In the International Study on Cerebral Vein and Dural Sinus Thrombosis (ISCVT) cohort (624 patients with cerebral vein and dural sinus thrombosis), we analyzed the predictors and the impact on outcome of diagnostic delay. Primary outcome was a modified Rankin Scale score >2 at the end of follow-up. Secondary outcomes were modified Rankin Scale score 0 to 1 at the end of follow-up, death, and visual deficits (visual acuity or visual field).
Results:
Median delay was 7 days (interquartile range, 3 to 16). Patients with disturbance of consciousness (P<0.001) and of mental status (P=0.042), seizure (<0.001), and with parenchymal lesions on admission CT/MR (P<0.001) were diagnosed earlier, whereas men (P=0.01) and those with isolated intracranial hypertension syndrome (P=0.04) were diagnosed later. Between patients diagnosed earlier and later than the median delay, no statistically significant differences were found in the primary (P=0.33) and in secondary outcomes: modified Rankin Scale score 0 to 1 (P=0.86) or deaths (P=0.53). Persistent visual deficits were more frequent in patients diagnosed later (P=0.05). In patients with isolated intracranial hypertension syndrome, modified Rankin Scale score >2 at the end of follow-up was more frequent in patients diagnosed later (P=0.02).
Conclusions:
Diagnostic delay was considerable in this cohort and was associated with an increased risk of visual deficit. In patients with isolated intracranial hypertension syndrome, diagnostic delay was also associated with death or dependency.
