May support noninvasive screening for innominate vein stenosis in pacemaker patients; leaves open prospective validation versus angiography.
Does combined sonography, pulse Doppler, and color flow accurately detect severe innominate vein or SVC stenosis due to thrombosis in patients with pacemakers compared to digital subtraction angiography?
Combined sonography, pulse Doppler, and color flow provides a highly sensitive and specific noninvasive method for detecting severe innominate vein or SVC stenosis in pacemaker patients.
