Simultaneous Type A Aortic Dissection, Pulmonary Thromboembolism, and Deep Vein Thrombosis in a COVID-19 Patient: A Case Report Study

Introduction: COVID-19 has been associated with an elevated risk of vascular complications, such as thromboembolism and arterial dissections, which can lead to adverse patient outcomes. The simultaneous occurrence of type A aortic dissection, pulmonary thromboembolism, and deep vein thrombosis in a COVID-19 patient is an unusual presentation that poses unique diagnostic and therapeutic challenges. This case aims to raise awareness of these rare complications, their clinical significance, and the challenges of managing these conditions during the COVID-19 pandemic. This report describes a COVID-19 patient presenting with type A aortic dissection, pulmonary thromboembolism, and deep vein thrombosis. Case Presentation: A 42-year-old man, a former opium user who had been abstinent for three years, was admitted to a general hospital in Qom, Iran, on January 24, 2023. While the patient had a family history of lung disease, he had no other notable risk factors or underlying conditions. Upon admission, he exhibited shortness of breath, severe chest pain, and fever. Initial examination revealed an axillary temperature of 38°C, occasional coarse crackles on lung auscultation, but no heart murmur. Blood pressure and pulse were equal in both arms and legs. A non-contrast spiral chest CT showed generalized bilateral ground-glass opacities, indicative of COVID-19. CT angiography revealed a type A aortic dissection extending from the origin of the aorta to the midpoint of the arch. Additionally, CT angiography identified bilateral segmental pulmonary artery thromboembolism. The patient also had deep vein thrombosis along with pulmonary thromboembolism. Emergency surgery was performed to replace the bentall aortic valve and repair the dissection. Unfortunately, the patient experienced cardiac arrest following the surgery, and resuscitation attempts were unsuccessful. Conclusions: This case of a COVID-19 patient with a complex presentation of concurrent type A aortic dissection, pulmonary thromboembolism, and deep vein thrombosis highlights the need for heightened clinical vigilance and prompt interdisciplinary collaboration to manage such life-threatening events. It underscores the importance of investigating the pathophysiology of severe vascular complications in COVID-19 to support the development of targeted therapies. This case emphasizes the necessity of early clinical detection and timely intervention to improve patient outcomes. Rapid diagnosis and treatment are essential to enhance outcomes in clinical situations of this nature.
