Acute Ischemic Stroke in Late Pregnancy Treated with Intravenous Thrombolysis and Endovascular Therapy

Pregnancy has usually been an exclusion criterion in clinical trials with thrombolysis and endovascular therapy in acute ischemic stroke. For that reason, these therapies are not recommended causing lack of evidence and vice versa. In this case report, we describe a pregnant woman in week 33 + 3 presenting with acute ischemic stroke, which was successfully treated with systemic thrombolysis and endovascular therapy, resulting in a good clinical outcome for both mother and child. The altered fibrinolytic system and the risk factors related to pregnancy constitute a challenge for clinicians when choosing the most suitable treatment modality for treating acute ischemic stroke in pregnancy. It is still uncertain whether thrombolysis in combination with endovascular therapy or endovascular therapy alone is the most appropriate treatment option. However, there is slowly growing evidence that thrombolysis and thrombectomy in pregnancy are feasible and safe with a good clinical outcome for both the mother and the child

Perfusion Changes in Acute Stroke Treated with Theophylline as an Add-on to Thrombolysis:A Randomized Clinical Trial Subgroup Analysis

PURPOSE: Theophylline has been suggested to have a neuroprotective effect in ischemic stroke; however, results from animal stroke models and clinical trials in humans are controversial. The aim of this study was to assess the effect of theophylline on the cerebral perfusion with multiparametric magnetic resonance imaging (MRI). METHODS: The relative cerebral blood flow (rCBF), relative cerebral blood volume (rCBV), and relative mean transit time (rMTT) in the infarct core, penumbra, and unaffected tissue were measured using multi-parametric MRI at baseline and 3‑h follow-up in patients treated with theophylline or placebo as an add-on to thrombolytic therapy. RESULTS: No significant differences in mean rCBF, rCBV, and rMTT was found in the penumbra and unaffected tissue between the theophylline group and the control group between baseline and 3‑h follow-up. In the infarct core, mean rCBV increased on average by 0.05 in the theophylline group and decreased by 0.14 in the control group (p < 0.04). Mean rCBF and mean rMTT in the infarct core were similar between the two treatment groups. CONCLUSION: The results indicate that theophylline does not change the perfusion in potentially salvageable penumbral tissue but only affects the rCBV in the infarct core. In contrast to the penumbra, the infarct core is unlikely to be salvageable, which might explain why theophylline failed in clinical trials.

COVID-19 did not result in increased hospitalization for stroke and transient ischemic attack:A nationwide study

BACKGROUND: The risk of thrombosis increases in infectious diseases, yet observational studies from single centers have shown a decrease in admission of acute ischemic stroke patients during the COVID‐19 pandemic. To investigate unselected stroke admission rates we performed a nationwide study in Denmark. METHODS: We extracted information from Danish national health registries. The following mutually exclusive time periods were compared to the year before the lockdown: (1) first national lockdown, (2) gradual reopening, (3) few restrictions, (4) regional lockdown, and (5) second national lockdown. RESULTS: Generally, admission rates were unchanged during the pandemic. In the unadjusted data, we observed a small decrease in the admission rate for all strokes under the first lockdown (incidence rate ratio: 0.93, confidence interval [CI]: 0.87–0.99) and a slight increase during the periods with gradual reopening, few restrictions, and the regional lockdown driven by ischemic strokes. We found no change in the rate of severe strokes, mild strokes, or 30‐day mortality. An exception was the higher mortality for all strokes during the first lockdown (risk ratio: crude 1.30 [CI: 1.03–1.59]; adjusted 1.17 [CI: 0.93–1.47]). The quality of care remained unchanged. CONCLUSION: Stroke admission rates remained largely unchanged during the pandemic, while an increased short‐term mortality rate in patients admitted with stroke observed during the first lockdown was seen, probably reflecting that the more frail patients constituted a higher proportion of admitted patients at the beginning of the pandemic
