A CASE OF SUCCESSFUL CONSERVATIVE TREATMENT FOR POPLITEAL ARTERY STENOSIS DUE TO ACUTE DISSECTION CAUSED BY BLUNT TRAUMA

Abstract

　　A 69-year-old male was taken to a local hospital for blunt trauma to his knee. In the ER, his right anterior and posterior tibial arteries were pulseless. A CT scan revealed severe stenosis in his right popliteal artery. He was transferred to our hospital for possible arterial reconstruction. On arrival at our hospital, Doppler ultrasound showed dissection of the popliteal artery with thrombosed false lumen. Angiogram of his right lower extremity showed stenosis of his popliteal artery with no perfusion delay. Because the blood flow to his right foot was recovering with time, conservative treatment was chosen and he was put under close observation. After a week, Doppler ultrasound showed shrinkage of the false lumen with no sign of stenosis. His anterior tibial arteries became palpable. The patient was discharged after 4 months with good blood flow to his right foot.
