ABSTRACT
BACKGROUND: Coagulopathy induced by COVID-19 has received much attention. Arterial and venous thrombosis of multiple organs due to COVID-19-related coagulopathy is associated with a poor outcome. CASE PRESENTATION: A 67-year-female was transferred to our hospital in need of intensive care for severe COVID-19 pneumonia. On day 7 after admission, despite the treatments, her respiratory and hemodynamic status deteriorated. Computed tomography revealed massive ascites and free air as well as wall defects of the transverse colon. An emergency laparotomy was undertaken in the intensive-care unit, and 17 cm of the transverse colon was resected. Histopathological findings revealed two perforation sites of 25 and 7 mm in diameter, necrosis of the intestinal mucosa around the perforation sites, and the microcirculatory thrombosis in the mesentery vessels which was suspected of having been induced by COVID-19-related coagulopathy. CONCLUSIONS: The case highlights the risk of intestinal ischemia and perforation induced by COVID-19 coagulopathy. Physicians treating COVID-19 should recognize the risk and evaluate patients carefully.
ABSTRACT
BACKGROUND: Anticoagulant therapy for patients with severe coronavirus disease (COVID-19) pneumonia is considered to improve the hypercoagulable and inflammatory state. However, bleeding complications should also be considered. CASE PRESENTATION: A 77-year-old man with a history of falls was diagnosed with COVID-19. Owing to his severe condition, he was intubated and transferred to our hospital for intensive care. Favipiravir, tocilizumab, unfractionated heparin, and ART-123 were administered to treat COVID-19 and manage the antithrombotic prophylaxis for paroxysmal atrial fibrillation (Af). On the 6th day after admission, a hematoma was noted on the left chest wall. Computed tomography (CT) revealed multiple hematomas, including hematomas on his chest wall and obturatorius internus muscle. Emergency angiography transcatheter embolization (TAE) was performed. The patient was transferred to another hospital 23 days after TAE, without complications. CONCLUSION: Our findings show that anticoagulation therapy and a history of falls induced multiple hematomas in a COVID-19 patient and that the condition was managed with TAE. When anticoagulants are considered in the management of Af and COVID-19 associated coagulopathy, it is necessary to closely monitor potential bleeding complications.
ABSTRACT
BACKGROUND: Some patients with coronavirus disease 2019 (COVID-19) develop pneumothorax. Tube thoracotomy and bulla resection could generate aerosols and cause virus transmission; the optimal treatment strategy remains unclear. CASE PRESENTATION: A 57-year-old male was transferred as a severe COVID-19 pneumonia case. On the 16th day after admission, the patient's respiratory condition deteriorated, and the chest X-ray revealed the presence of severe right-sided pneumothorax. A chest drain was immediately inserted; however, a significant air leak continued, and severe ventilator settings were required. Thus, veno-venous extracorporeal membrane oxygenation (VV-ECMO) treatment was initiated to allow the lungs to rest. After 10 days of lung-protective ventilation, the patient was weaned from ECMO and the chest drain was removed on the following day with no major comorbidities. CONCLUSION: The combination of ECMO with lung rest strategy could be a treatment option for intractable pneumothorax with COVID-19 to avoid unnecessary surgical procedures and aerosol generation.
