Femoral arterial shot

Introduction Peripheral vascular signs refer to changes in pulsation or waveforms of blood vessels that are found when examining surrounding blood vessels under certain disease conditions. Femoral artery shots are one of the manifestations.

Cause

Because of the multiple manifestations of peripheral vascular signs, the mechanism of action is not the same, leading to the most common disease of peripheral vascular signs of aortic valve insufficiency. When the aortic valve is insufficiency, the heart's compensatory contraction is enhanced, so that during the systole, there is enough blood to shoot the aorta or even the small arteries, so that the systolic blood pressure rises, the pulse is strong and powerful, and the flood veins appear. In the diastolic phase, due to aortic regurgitation, a large amount of blood in the aorta is refluxed to the left ventricle, causing compensatory contraction of the aorta, arterioles, and capillaries, thus the difference between arterial systolic pressure and diastolic blood pressure. Increase, form a series of peripheral vascular signs such as water pulse, gunshot sound, Duroziez double tone and capillary pulsation.

In the pathological case, the chest piece of the stethoscope is lightly placed on the cerebral artery or femoral artery of the patient, and the sound of "Kiichi, Kayi" can be heard, which is called a gunshot sound.

Differential diagnosis

Aortic insufficiency can present peripheral vascular signs: Corrigan's pulse, Quincke's sign, Traube's sign, femoral systolic and diastolic double murmurs ( Duroziez's sign), and the head's up-and-down swing with the heart rate (de-Musset'ssign).

Periarterial patent ductus arteriosus can appear peripheral vascular signs, such as capillary pulsation, water pulse and femoral artery gunshots; there is significant pulmonary hypertension, there is a difference of cyanosis. In the pathological case, the chest piece of the stethoscope is lightly placed on the cerebral artery or femoral artery of the patient, and the sound of "Kiichi, Kayi" can be heard, which is called a gunshot sound.
