Subclavian artery stenosis was defined as ≥15 mm Hg interarm pressure difference. Results The prevalence of SS was 1.9% in the free-living cohorts and 7.1% in the clinical cohorts; SS was significantly (p < 0.05) associated with past smoking (odds ratio [OR] = 1.80), current smoking (OR = 2.61), and higher levels of systolic blood pressure (OR = 1.90 per 20 mm Hg).

Additionally, no systolic blood pressure difference was noted in terms of subclavian artery stenosis (149,8 mmHg vs. 146,4 mmHg, P=0.78). Table 2 compares patients with subclavian artery stenosis and without who undergoing carotid endarterectomy. Subclavian artery stenosis was defined as occlusion in the first part of the subclavian artery causing stenosis which was diagnosed through either: asymmetric blood pressure detected in the upper extremities (interarm SBPD of at least 15 mm Hg), doppler ultrasonographic or angiographic evidence of >60% subclavian stenosis, or 100% occlusion, or symptoms compatible with SAS. A significant difference (more than 20 mm Hg) in blood pressure or in pulses between both arms A change in color (bluish discoloration) of the fingers in the affected extremity (in severe instances) When symptoms are noticeable, your healthcare provider should be notified right away; imaging tests may be performed to evaluate the blood flow from the subclavian artery. 2011-10-14 · The difference of 15 to 20 mm Hg or more in systolic bilateral brachial arterial blood pressure measurements provides important clinical information in patients with subclavian steal syndrome. Complementary to duplex sonographic scanning, radiologists use computerized tomography angiography, magnetic resonance angiography, and digital subtraction angiography for preoperative planning.

Critical stenosis or occlusion of the subclavian artery proximal to the vertebral artery. More common on the left side (4:1 ratio left to right), more common in males, relatively benign condition. Results in retrograde blood flow in the ipsilateral vertebral artery (collateral flow). Leads to blood pressure difference left / right arm.

Blood pressure difference > 15 mm Hg between arms indicates subclavian stenosis.

Subclavian stenosis blood pressure difference

A side‐to‐side difference in systolic brachial arterial blood pressure is a common finding in subclavian artery stenosis and is frequently used as a screening tool for subclavian steal syndrome (SSS). Subclavian artery stenosis can be identified by an inter-arm blood pres-sure difference of 15 mmHg and is present in 1.9% of the whole population and 7% of the clinical population [1].

Without a significant difference in blood pressure between the patient’s arms, proximal subclavian stenosis or occlusion cannot be present.

We sought to describe the epidemiology of SS and determine its found a 99% negative predictive value using a systolic blood pressure difference cut-off of > 10 mmHg (with a positive predictive value of 13%). Similar studies with much fewer subjects but using a systolic cut-off of 15 and 20 mmHg found positive predictive values of 100% and 67%, respec-tively, both with 100% negative predictive values.10,11 As A blood pressure difference between the two arms > 20 mmHg may be present in patients who have SSS. 4 In one study, a blood pressure difference > 50 mm Hg was associated with symptoms of SSS in 38.5% of patients.

Classic subclavian steal — Subclavian artery occlusion or a hemodynamically significant stenosis proximal to the origin of the vertebral artery results in lower pressure in the distal subclavian artery . As a result, blood flows from the contralateral vertebral artery to the basilar artery and may flow in a retrograde direction down the ipsilateral vertebral artery, away from the brainstem .

Shadman et al. [3] reported that significant subclavian stenosis is present in 7% of the clinical population and that subclavian artery stenosis (inter-arm systolic BP differ- A blood pressure difference between the two arms > 20 mmHg may be present in patients who have SSS. 4 In one study, a blood pressure difference > 50 mm Hg was associated with symptoms of SSS in 38.5% of patients. Screening can be done with color Doppler or transcranial Doppler ultrasound as it is non-invasive and may be performed at bedside. We noted inter-arm blood pressure difference of 30 mmHg, with higher, hypertensive values on right arm.

Severe stenosis of the spine can destroy lives, leading to paralysis and other complications, such as incontinence, balance issues, weakness and numbness. It's therefore important to recognize the signs and symptoms early on and seek treatm

Further workup and medical imaging excluded aortic stenosis and revealed an asymptomatic, hemodynamically significant, stenosis of left subclavian artery.
