ABSTRACT
Coronavirus disease 2019 (COVID-19) began to spread in December 2019 and was declared a pandemic by WHO on 11 March 2020. Pulmonary embolism (PE) is a known sequel to COVID-19 infection. Many patients showed worsened symptoms of thrombotic events of pulmonary arteries during the second week of the disease for which computed tomography pulmonary angiography (CTPA) is recommended. The most frequent complications in critically ill patients are prothrombotic coagulation abnormalities and thromboembolism. So, this study aimed to assess the prevalence of PE in patients with COVID-19 infection and to evaluate the relation to disease severity on CTPA findings. Methods: This cross-sectional study was performed to evaluate the patients who tested positive for COVID-19 and underwent CTPA. COVID-19 infection in participants was confirmed by a PCR of nasopharyngeal or oropharyngeal swab samples. Frequencies of computed tomography severity scores and CTPA were calculated and compared with clinical and laboratory findings. Results: The study included 92 patients with COVID-19 infection. Positive PE was found in 18.5% of the patients. The mean age of the patients was 59.83±13.58 years with an age range of 30-86 years. Among the total participants, 27.2% underwent ventilation, 19.6% died during treatment, and 80.4% of them got discharged. PE was developed in patients who did not receive prophylactic anticoagulation, which is statistically significant (P≤0.001). There was also a significant relationship between mechanical ventilation and CTPA findings. Conclusions: The authors conclude from their study that PE is one of the complications of COVID-19 infection. Rising D-dimer during the second week of disease alerts clinicians to do CTPA to exclude or confirm PE. This will help in the early diagnosis and treatment of PE.
ABSTRACT
Diagnostic radiology plays a crucial role in children. The pediatric population has been less studied than the adult population since the initial period of the COVID-19 pandemic to date. Realizing the potential utility of structured reporting, different guidelines and international consensus statements regarding COVID-19 in the pediatric population have been released in recent times. Different clinical and radiological manifestations in children have been evolving in this period of uncertainty and are different from the adult population in certain aspects. Apart from the involvement of lungs, a multisystemic inflammatory syndrome in children or pediatric multi systemic inflammatory syndrome is unique in children. Therefore, awareness of the recent consensus, structural uniform reporting and multi-organ involving patterns in COVID-19 can guide radiologists for a better understanding of this complex novel disease leading to early diagnosis and timely treatment of affected children.
