Insights
Computed tomography (CT) revealed acute cerebrovascular complications in severely ill coronavirus disease 2019 (COVID-19) patients. COVID-19-associated coagulopathy may increase the risk of ischemic and hemorrhagic infarction.
Area of Science:
- Neurology
- Radiology
- Infectious Diseases
Background:
- Severely ill patients with coronavirus disease 2019 (COVID-19) admitted to the intensive care unit are at risk for acute cerebrovascular complications.
- Computed tomography (CT) is a key imaging modality for diagnosing these complications.
Purpose of the Study:
- To report the CT features of acute cerebrovascular complications in critically ill COVID-19 patients.
- To investigate the association between COVID-19 and cerebrovascular events.
Main Methods:
- Retrospective analysis of 29 intensive care unit patients with confirmed COVID-19.
- Brain CT scans were analyzed for cerebrovascular complications.
- Demographic, clinical, and laboratory data (including coagulation and C-reactive protein) were collected.
Main Results:
- CT revealed acute cerebrovascular complications in 6 out of 27 eligible patients (22%).
- The affected patients ranged in age from 49 to 81 years.
- No complications were observed in the remaining 21 patients (aged 36-82 years).
Conclusions:
- Radiologists must recognize the risk of cerebrovascular complications in COVID-19 patients.
- COVID-19-associated coagulopathy is likely multifactorial, increasing the risk of both ischemic and hemorrhagic infarction.
Objective:
To report the computed tomography (CT) features of acute cerebrovascular complications in severely ill patients with confirmed coronavirus disease 2019 (COVID-19) in the intensive care unit.
Materials And Methods:
We conducted a retrospective analysis of 29 intensive care unit patients with confirmed COVID-19 who underwent CT of the brain. We describe the CT features of the cerebrovascular complications of COVID-19, as well the demographic characteristics and clinical features, together with the results of laboratory tests, such as complete blood cell count, coagulation testing, renal function testing, and C-reactive protein assay.
Results:
Two patients were excluded because of brain death. Among the remaining 27 patients, CT revealed acute cerebrovascular complications in six (three men and three women; 49-81 years of age), whereas no such complications were seen in 21 (15 men and six women; 36-82 years of age).
Conclusion:
Radiologists should be aware of the risks of cerebrovascular complications of COVID-19 and the potential underlying etiologies. COVID-19-associated coagulopathy is likely multifactorial and may increase the risk of ischemic and hemorrhagic infarction.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
