Vascular murmur

The vascular murmur check is an auxiliary test method for checking whether the blood vessel is normal. Vascular murmurs have arterial and venous murmurs. Arterial murmurs are often found in the middle or abdomen. The noise is generated by the blood flowing in the blood vessels, when the blood flow is accelerated or because the blood flow passes through the narrow to a wider area, or the blood flow through the abnormal passage causes the blood flow to vortex and cause the blood vessel wall to vibrate. Through this examination, the lesion and the corresponding symptoms can be judged. Basic Information Specialist classification: growth and development check classification: physical examination Applicable gender: whether men and women apply fasting: not fasting Tips: Maintain a normal diet and schedule. Severe blood vessels and cardiac dysfunction are not suitable for this test. Normal value Normal blood vessels generally do not produce murmurs, and vascular noise produces the same as heart murmurs, depending on the vortex field. Clinical significance Abnormal results systolic vascular murmurs (jet murmurs) in the middle of the abdomen often suggest abdominal aortic aneurysms or abdominal aortic stenosis. The former can touch the pulsating mass in the part; the latter is weakened, the lower limb blood pressure is lower than the upper limb, and the severe one cannot touch the dorsal artery of the foot. Such as systolic vascular murmur in the left and right upper abdomen, often suggesting renal artery stenosis, can be seen in young hypertensive patients. If the noise is on both sides of the lower abdomen, radial artery stenosis should be considered. When the left lobe liver cancer compresses the hepatic artery or the abdominal aorta, a squeaky noise can be heard at the mass of the mass or a slight continuous murmur can be heard at the tumor site. Venous murmurs are continuous snoring sounds with no systolic and diastolic properties. Often appear in the umbilical or upper abdomen, especially when the abdominal varices are severe, often suggesting portal hypertension with collateral circulation. Regular physical examination items for people who need to be examined, abnormal blood vessels. Precautions Forbidden before examination: Maintain a normal diet and schedule. Requirements for examination: The patient actively cooperates with the doctor during the examination. It is not suitable for strenuous exercise one hour before the examination. It is not appropriate to be overly stressed during the examination, so as not to affect the result. Inspection process The contents and methods of the examination are as follows: The doctor should pay attention to the examination of the vascular murmur, and the vascular murmur has arterial and venous murmurs. The systolic vascular murmur in the middle abdomen often indicates abdominal aortic aneurysm or abdominal aortic stenosis. The abdominal aortic aneurysm can reach the pulsating mass in this part; the abdominal aortic stenosis is weakened, the lower limb blood pressure is lower than the upper limb, and the severe foot can not touch the dorsal artery. Such as systolic vascular murmur in the left and right upper abdomen, often suggesting renal artery stenosis, can be seen in young hypertensive patients. If the noise is on both sides of the lower abdomen, radial artery stenosis should be considered. When the left lobe liver cancer compresses the hepatic artery or the abdominal aorta, a squeaky noise can be heard at the mass of the mass or a slight continuous murmur can be heard at the tumor site. Venous murmurs are continuous snoring sounds with no systolic and diastolic properties. Often appear in the umbilical or upper abdomen, especially when the abdominal varices are severe, often suggesting portal hypertension with collateral circulation. Not suitable for the crowd Inappropriate people: severe blood vessels and heart failure.
