2021-03-03 · Subclavian artery stenosis is a form of peripheral arterial disease (PAD). It may present with transient episodes of vertigo and circulatory symptoms involving the arms and hands Physical examination may demonstrate a weak pulse in one upper extremity and a systolic blood pressure difference of more than 10 millimeters of mercury (mmHg) between contralateral left and right upper extremities. The case of a 67-year-old woman with symptoms related to the vertebro-basilar system and blood pressure difference of the upper extremities is presented. Colour-Doppler imaging (CDI) with additional spectral tracing revealed partial subclavian steal syndrome with retrograde flow in the left vertebral artery during systole, which could be significantly enhanced by reactive hyperemia after of Establishing subclavian duplex criteria to characterize significant stenosis is crucial to identify patients that require further imaging modalities or treatment. Retro-grade vertebral flow was an absolute indicator of underlying subclavian occlusive disease. Color doppler imaging in the subclavian axillary region and upper extremity Clinical Imaging, Vol. 18, No. 3 Intravascular Stents in the Management of Acute Superior Vena Cava Obstruction of Benign Etiology Subclavian artery occlusion or significant stenosis proximal to the origin of the vertebral artery results in lower pressure in the distal subclavian artery. Blood flows from the contralateral vertebral artery to the basilar artery and may flow in a retrograde direction down the ipsilateral vertebral artery.

Duplex ultrasound with color flow imaging is the noninvasive modality of choice in the evaluation of subclavian artery disease. Dampened or monophasic waveforms, turbulent color flow imaging, and increased velocities in the region of stenosis are characteristic findings of obstruction. This study evaluates the diagnostic value of the hemodynamic parameters of color Doppler flow imaging (CDFI) for severe (70 to 99%) subclavian artery stenosis (SAS) using digital subtraction angiography (DSA) as the reference standard.

Two were performed via manubriotomy and a third case via standard median sternotomy because of concomitant coronary revascularisation. There was complete symptomatic relief on follow-up, and radiological imaging confirmed subclavian steal in 3 patients; 1 patient showed segmental occlusion of innominate artery at its origin with focal stenosis of proximal left subclavian artery with retrograde flow in vertebral artery of right side only. The diagnosis of subclavian steal was made primarily using time-resolved CE MRA, which was quite reliable and Subclavian Steal Syndrome (SSS) refers to a vascular disorder, a rare form of periphery artery disease in which a blockage is present in a critical location within one of the Subclavian arteries which gives rise to problems involving the arm and the brain.

The prevalence of subclavian artery stenosis is 2.5 to 4.5 percent in patients referred for coronary artery bypass grafting . In the presence of a hemodynamically significant subclavian artery stenosis proximal to the origin of the ipsilateral IMA, flow through the internal mammary artery may reverse and "steal" flow from the coronary circulation during upper extremity exercise ( figure 3 ).

When sonography is limited, such as for the evaluation of subclavian disease, CT or MRI can be used to evaluate the anatomy. CTA Upper Extremity (Thoracic Outlet Syndrome, Subclavian stenosis, Paget-Schroetter) Reviewed By: Daniel Verdini, MD Last Reviewed: June 2020 Contact: (866) 761-4200, Option 1 In accordance with the ALARA principle, TRA policies and protocols promote the utilization of radiation dose reduction techniques for all CT examinations. A variety of noninvasive imaging modalities can be selectively used to diagnose subclavian stenosis when a steal phenomenon is suspected. Continuous wave Doppler and duplex ultrasonography are readily accessible, inexpensive, and accurate when performed by an experienced operator. 12 Transcranial Doppler may be more useful in the setting of neurological symptoms. Duplex ultrasound with color flow imaging is the noninvasive modality of choice in the evaluation of subclavian artery disease.
