COVID-19 disease is known to cause pulmonary and extrapulmonary complications including effects on cardiovascular, gastrointestinal, renal, and neurovascular system. Ischemic stroke seems to be one of the most serious neurologic complications in patients with COVID-19 infection. In this case report, we have documented, 70-year-old male presented with acute respiratory syndrome with hypoxemia and neurological involvement as right hemiparesis with altered level of consciousness, COVID-19 real-time polymerase chain reaction positive, with abnormal laboratory parameters such as ferritin, lactate dehydrogenase, and D-dimer. Further investigations such as echocardiography documented cardiomyopathy and left heart dysfunction, high-resolution computed tomography thorax documented COVID pneumonia, and magnetic resonance imaging brain documented left frontoparietal and parieto-occipital lobe infarct. We have observed excellent clinical and radiological response to anticoagulation, antiplatelets, and steroids with other supportive care in critical care unit.

| Introduction|| |
The evidence from SARS-CoV-2 studies implies that the virus can have central nervous system involvement., Other reports suggest a prothrombotic state with COVID-19. Since the coronavirus pandemic in 2020, there has been an ever-growing evidence of neurologic complications associated with COVID-19. Retrospective study form China with 214 COVID-19 patients reported four ischemic strokes. The report suggests that the neurologic complications were seen in patients with severe COVID-19. Furthermore, abnormalities in liver enzyme, hemoglobin, lactate dehydrogenase (LDH), d-dimer, Cr, and lymphopenia were more common in patients with neurologic complications. Patients with COVID-19 tend to be in a prothrombotic state. On the other hand, increased prothrombin time, partial thromboplastin time, and decreased platelet counts are also reported in COVID-19, which may increase the risk of hemorrhagic incidents. This is especially important in patients with cerebrovascular diseases.

High-resolution computed tomography (HRCT) thorax documented abnormalities as – bilateral peripheral, subpleural to central airspace opacities in upper lobe, middle lobe, and lower lobe [Figure 4] and [Figure 5] suggestive COVID-19 pneumonia, require COVID-19 RT PCR for confirmation, CORAD-4, computed tomography severity score-12/25 [Figure 6].

We have started anticoagulation with low molecular weight heparin (LMW0 injection 60 units BID, injection methylprednisolone 40 mg IV TDS, injection remdesivir, oral formulations of Aspirin 75 mg OD, and oxygen supplementation with target SpO2 more than 95% and other supportive care in critical care unit. Clinical response documented after 14 days of treatment, with near complete neurological recovery, consciousness recovered, neurodeficit recovered, right upper limb and lower limb tone improved, Grade 4-Grade 5 power regained, deep tendon reflexes were normal, plantar reflexes documented flexor response. Respiratory system parameters were improved after 7 days of treatment, SpO2 marinating 95% at room air, fatigability decreased and able to perform breathing exercises and walk across room with minimal respiratory discomfort. We have discharged patient after neurological recovery and 6 min walk parameters are acceptable and having saturation more than 93% at room air.
| Discussion|| |
While details of the pathogenesis of ischemic stroke in COVID-19 are still emerging, current evidence suggests putative mechanisms. In the study of Mao et al., 5.7% of patients with severe infection developed cerebrovascular disease later in the course of illness. In a study by Li et al., the incidence of stroke in COVID-19 patients was about 5% with a median age of 71.6 years. These patients were associated with severe disease and had a higher incidence of risk factors such as hypertension, diabetes, coronary artery disease, and previous cerebrovascular disease. Average time of onset of stroke after COVID-19 diagnosis was 12 days. Elevated levels of CRP and D-dimer indicating a high inflammatory state and abnormalities with the coagulation cascade, respectively, might play a role in the pathophysiology of stroke in the setting of COVID-19 infection.
The SARS-CoV-2 virus is the seventh known variant of coronavirus that infects humans. SARS-CoV-2 is genetically similar to SARS-CoV-1. SARS-CoV-1 in 2003 affected about 8000 patients with few reports of neurological manifestations – mostly peripheral neuropathy and encephalitis. Similar to SARS-CoV-1, the current SARS-CoV-2 affects the neurological system in about 36.7% of patients as per Mao et al. Most coronaviruses are neurotropic, and others speculate that SARS-CoV-2 is neurotropic too. Furthermore, there are reports of SARS-CoV-2 being identified in cerebrospinal fluid by PCR. Angiotensin-converting enzyme-2 (ACE) receptors are the major entry points for SARS-Cov-2 and other coronaviruses. Although ACE-2 receptors are present in the nervous system, alternate pathways have been proposed to explain the entry of SARS-CoV-2 into the nervous system including direct injury to the blood and blood–brain barrier, hypoxic injury, and immune-related injury.,
Evidence of abnormal coagulation parameters associated with COVID-19 appeared in early reports from China. The first report of 99 hospitalized patients in Wuhan showed that inflammatory biomarkers of interleukin-6, erythrocyte sedimentation rate, CRP, D-dimer, and other coagulation parameters were increased or deranged. High levels of D-dimer were observed in the present review which might be due to COVID-19-associated inflammation and the consequent downstream triggering of coagulation cascade.
Higher age and CRP levels were observed among patients symptomatic for COVID-19 at the time of diagnosis of stroke. Reports elucidating differences between COVID-19 positive and COVID-19 negative strokes have also found higher levels of inflammatory biomarkers among the former.
Strokes in patients with COVID-19 may be due to usual causes such as atherosclerosis, hypertension, and atrial fibrillation. Three main mechanisms appear to be responsible for the occurrence of ischemic strokes in COVID-19. These include a hypercoagulable state, vasculitis, and cardiomyopathy.
All patients admitted to intensive care should receive prophylaxis against venous thrombosis, with at least LMW heparin. Tang et al. reported that anticoagulation reduced mortality in COVID-19 patients with coagulopathy. In reply, Asakura and Ogawa noted that some features of the coagulopathy in COVID-19 suggest Disseminated intravascular coagulation (DIC) and recommended a combination of heparin and nafamostat mesylate, a treatment used for DIC in Japan. Thachil et al. responded with a discussion of possible benefits of unfractionated heparin versus LMW heparin.
Beigel et al. reported that, in a randomized controlled trial in 1059 patients hospitalized for COVID-19, remdesivir was associated with a shorter median recovery time (11 days, 95% confidence interval [CI]: 9–12), compared with placebo (15 days, 95% CI: 13–19), and a lower 14-day mortality of 7.1% with remdesivir versus 11.9% with placebo (hazard ratio for death, 0.70; 95% CI: 0.47–1.04). Stroke was not mentioned in the report.
We have documented a significant role of anticoagulation, antiplatelets, remdesivir, and methylprednisolone.
Key learning points from this case report are:
- COVID 19 disease is known to cause pulmonary and extrapulmonary complications including effects on cardiovascular, gastrointestinal, renal, and neurovascular system
- Neurovascular complications such as stroke, venous thrombosis, encephalopathy, and vasculitis is documented in various studies
- We have documented, embolic stroke in this case in COVID-19 secondary to hypercoagulability and cardiomyopathy
- Early interventions such as anticoagulation and antiplatelets have a crucial role in early clinical recovery
- Timely steroid use has positive impact on both COVID pneumonia and stroke outcome
- We recommend, all cases with stroke should undergo HRCT thorax in current scenario as many of these cases may have less respiratory symptoms, and in stroke cases with SpO2 <95% warrants lung pathology to be ruled out to have satisfactory treatment outcome.
