If a stronger pulse is palpated in the right neck than the left, which condition is least likely to cause this?

When considering the scenario of a stronger pulse in the right neck compared to the left, it's important to analyze each condition's impact on blood flow and pulse strength.

Innominate occlusion, or blockage of the innominate artery, would typically affect both the right common carotid artery and the right subclavian artery. This occlusion would lead to decreased blood flow to the right neck, resulting in a weaker pulse on that side rather than a stronger one. Therefore, it is least likely to cause a stronger pulse in the right neck compared to the left.

In contrast, right carotid occlusion would directly affect blood flow from the right common carotid artery itself, potentially leading to diminished pulse strength but not facilitating a stronger pulse. Hemodynamically significant stenosis could actually enhance blood flow beyond the site of stenosis due to compensatory mechanisms, which might create stronger pulses in certain areas depending on collateral circulation. Subclavian steal syndrome involves reverse flow in the vertebral artery due to significant stenosis or occlusion in the subclavian artery, which can alter blood flow dynamics and maybe create asymmetric pulses, but it is not the condition least likely to cause the observed pulse disparity in the neck.

By this reasoning, innom
