Free floating thrombosis of aorta in three patients with COVID-19 infection

Abstract

There is evidence that current coronavirus disease (COVID-19) is responsible for thromboembolic events in a number of affected patients. One of this potential thrombotic event is aortic free floating thrombosis (FFT). We report three cases of aortic FFT in COVID-19 patients. All three cases were female. The first case had mesenteric ischemia with descending thoracic aorta (DTA) FFT. The patient underwent resection and anastomosis of small intestine and stent graft placement in DTA. The second patient had right lower extremity ischemia and abdominal aortic FFT. This patient underwent open aortic and right femoral thromboembolectomy. The third patient had mesenteric ischemia and FFT of abdominal aorta. This patient was managed by resection and anastomosis of small intestine, splenectomy and anticoagulation. All three patients were discharged from the hospital in appropriate condition. FFT of aorta is a potential complication of current COVID-19 infection. Precise attention is necessary to diagnose and manage this condition and prevent further complications.
