Successful Systemic Heparinization for Treatment of Acute Arterial Occlusion of Tibial Artery and Aortic Mural Thrombi in a Patient With COVID-19 Infection: A Case Report

ABSTRACT

The present case report described a 60-year-old woman who developed multiple isolated acute arterial occlusions of the left anterior tibial artery, peroneal artery, and posterior tibial artery with aortic mural thrombi in the infrarenal aorta during treatment of COVID-19 pneumonia. The patient underwent conservative treatment by systemic heparinization and switched to low molecular weight heparin. She experienced clinical improvement within hours of medical treatment and complete resolution of the tibial artery thrombosis after two weeks of treatment. The aortic mural thrombi was evaluated by computed tomography angiography (CTA) abdomen and lower extremities and resolved after six weeks of anticoagulant administration. © 2022 JOURNAL OF THE MEDICAL ASSOCIATION OF THAILAND.
