I am wondering if someone has heard of having high blood pressure only in the legs. Both legs are a consistent high blood pressure while the arms are normal? Any ideas what this could be from? I have tried searching everything and can't seem to find any mention of why there could be high blood pressure in the legs and not arms
What tests have you had?
I did some reading about PAD and DVT and think you may be referring to an ankle brachial index (ABI).
In this test, the systolic blood pressure is checked in the ankle area. It is measured before and after an exercise. If the systolic blood pressure after an exercise is not the normal ankle pressure, it indicates intermittent claudication.
Perhaps you had this test:
A Doppler study
This test is used for checking the blood flow in the legs and to assess the severity of lower extremity atherosclerotic disease. Blood pressure cuffs are placed in four locations on the legs, from the top of the leg to the ankle. A fifth cuff is used to measure the blood pressure in the brachial artery in the arm. Then the blood pressures in the arms/legs are compared. Normal blood pressure in the ankle is 90% of the arm pressure. It will be less than that if narrowing of the arteries is present. People with blockages often develop collateral circulation. This results in differences in blood pressure of extremities which is more noticable during exercise.
Blood pressure difference of 20mmHg or more between the upper and lower extremities could indicate coarctation of aorta.
PS. You should look up bilateral subclavian artery stenosis, which results in a higher blood pressure in the legs than arms. It is not very common though.
