Duroziez’s sign is generally referred to as an arterial double murmur, which is a back and forth systolic and diastolic murmur heard during auscultation. An arterial double murmur is usually heard as a gunshot-like sound in the brachial or femoral arteries due to an increase in pulse pressure during auscultation with a stethoscope, and a systolic and diastolic murmur can be heard when pressure is applied to the stethoscope. The double arterial murmur is common in patients with aortic valve insufficiency, hyperthyroidism, and severe anemia, and is caused by increased pulse pressure and blood flow back and forth under the stethoscope. If this sound is heard during auscultation, it is usually judged based on the patient’s other clinical symptoms and imaging tests. It is recommended that the patient consult a doctor in time for professional and systematic examination, and carry out appropriate treatment under the guidance of the doctor.
