✦ Synopsis
We prospectively evaluated 59 patients who were deemed candidates for coronary bypass surgery after coronary artery angiography for subclavian artery narrowing, which could compromise the ipsilateral internal thoracic artery graft. Bilateral arm blood pressure (BP) measurements, auscultation for supraclavicular or cervical bruits, and questioning about cerebrovascular ischemic symptoms were compared to brachiocephalic-subclavian arteriography. One neurologic complication occurred during arteriography. An upper extremity BP difference of > or = 15 mm Hg identified all patients with > or = 50% subclavian artery narrowing. We recommend brachiocephalic-subclavian arteriography only in patients with abnormal noninvasive screening for subclavian stenosis, not routinely.
