femoral arteriotomy for coronary angiography.
We measured calf PPV in 8 male adult patients undergoing femoral arteriotomy for coronary angiography. One hour after catheterization, there was a 25.5% increase in PPV (p<0.025) in the non-catheterized leg but no significant change in the catheterized leg. All values returned to baseline on the following day. The increase in PPV in the non-catheterized leg was presumably due to volume expansion from fluids and contrast given during the procedure.
The absence of these changes in the catheterized leg can be explained by transient arterial spasm at the site of the arteriotomy.
