Endovascular Treatment for Lower-extremity Arterial Thrombosis in a Patient with Congenital Afibrinogenemia and a History of Bleeding Complications

抄録

Congenital afibrinogenemia is a rare autosomal recessive blood disorder that accompanies thrombotic complications and is associated with bleeding tendency. The management of these opposing complications remains a challenge. Endovascular treatment (EVT) for peripheral arterial thrombosis has not been described in previous studies. A 57-year-old man with congenital afibrinogenemia developed back pain and left lower leg pain. The cause of the pain was confirmed to be renal infarction and lower extremity arterial thrombosis by Doppler ultrasound and contrast-enhanced computed tomography. He was treated with EVT for the lower extremity arterial thrombosis, leading to an excellent short-term improvement without bleeding.
