Summary
Even mild coronavirus 2019 (COVID-19) can lead to dangerous blood clots. This case shows pulmonary emboli (PE) can occur without lung damage in mild COVID-19, highlighting a risk for venous thromboembolism (VTE).
Area of Science:
- Internal Medicine
- Cardiology
- Pulmonology
Background:
- Severe coronavirus 2019 (COVID-19) infection is known to cause thrombotic complications.
- Data on pulmonary emboli (PE) in mild COVID-19 cases is limited.
- Lung infiltrates, like ground-glass opacities, are often seen in mild COVID-19 imaging.
Observation:
- A 66-year-old man with mild COVID-19 presented with acute chest pain and shortness of breath.
- Chest CT angiogram revealed submassive PE in pulmonary arteries with right heart strain.
- No lung parenchymal infiltrates were observed on imaging.
Findings:
- This case highlights an uncommon occurrence of submassive PE in mild COVID-19 without lung infiltrates.
- Mild COVID-19 can induce a hypercoagulable state, leading to venous thromboembolism (VTE).
- The lungs may not be the primary source of COVID-19-associated coagulopathy in all cases.
Implications:
- Clinicians should consider VTE risk even in patients with mild COVID-19 and no significant lung involvement.
- This case broadens the understanding of COVID-19's thrombotic potential.
- Further research is needed to elucidate the mechanisms of coagulopathy in mild COVID-19.

226
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...

A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
