[Catheter-induced vascular lesions: a comparison of the diagnostic value of Doppler color sonography versus angiography].
One hundred and thirty-two patients with suspected lesions of the femoral arteries following diagnostic and/or therapeutic cardiac catheterisation were studied by colour Doppler sonography (CDS) and digital subtraction angiography (DSA) and the results were compared. CDS was unable to demonstrate 5 out of 23 av fistulae. Intra-arterial DSA showed all av fistulae found at operation. CDS showed lower reliability (95%) than DSA (100%) for the demonstration of pseudoaneurysms. CDS can indicate hematoma and thrombi in pseudo-aneurysms and their exact extent is better shown by sonography. Arterial dissections (2 cases) and intra-luminal thromboses or occlusions of the femoral artery (4 cases) are shown equally well by the two procedures.
