Subclavian steal syndrome affects the artery that supplies blood to the neck and head or the arteries that supply blood to the arms. Because of this, people may experience symptoms in these areas.

proximal subclavian artery usually cannot be seen well enough to assess; distal subclavian artery shows parvus-tardus waveform and monophasic waveform; CT. subclavian artery stenosis or occlusion is easily identified; delayed enhancement of ipsilateral vertebral artery; unable to determine the direction of flow in the vertebral artery

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. The subclavian stenosis or atresia can be documented by catheter X‐ray angiography, during which the reversal of vertebral artery flow can be demonstrated by selective injection of the contralateral vertebral artery. Angiography performed in the aortic arch and great vessels verified significant proximal left subclavian artery stenosis . After reviewing the benefits and risks with the patient, left subclavian artery angioplasty and stent intervention were performed ( Figure 3 ). Imaging studies that may be considered include duplex ultrasonography (US), computed tomography (CT) angiography (CTA), four-vessel cerebral arteriography, magnetic resonance angiography (MRA), and > subclavian stenosis > Arm swelling. Contraindications Parallel imaging is a newly developed technique used to reduce scan time without affecting the scan (B) Duplex ultrasound imaging begins with short-axis views of the subclavian artery obtained above the clavicle.

Continuous wave Doppler and duplex ultrasonography are readily accessible, inexpensive, and accurate when per-formed by an experienced operator.12 Transcranial Doppler may be more use- The various operations to correct subclavian stenosis include: axillary–axillary bypass, carotid–subclavian bypass, and transposition of the subclavian artery. Axillary–axillary Figure 2. Sagittal CTA image of proximal left subclavian stenosis. Figure 3. Proximal subclavian lesion pre-stenting.

Sonography is the initial imaging examination when subclavian steal syndrome is suspected. Ultrasound with pulsed Doppler spectral analysis can demonstrate patency and flow direction in the vertebral artery and can establish the presence of subclavian steal.

The subclavian stenosis or atresia can be documented by catheter X‐ray angiography, during which the reversal of vertebral artery flow can be demonstrated by selective injection of the contralateral vertebral artery.

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).

G., W.L.D.); and 24 Aug 2011 Similar to carotid artery stenosis, vertebral artery stenosis may cause The vertebral arteries usually arise from the first portion of the subclavian artery.

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.

There are several diagnostic modalities used to detect subclavian artery stenosis, which is the former key condition of the CSSS, such as computed tomography angiography, the combination of magnetic resonance imaging, angiography, or duplex ultrasound imaging, which may reveal abnormal vertebral artery flow as a sign of vertebral artery subclavian steal. Stenosis of left subclavian vein in thoracic outlet syndrome References [1] Fugate MW, Rotellini-Coltvet L, Freischlag JA (2009) Current management of thoracic outlet syndrome. C. Noninvasive imaging such as duplex ultrasound with color flow can provide anatomical and functional assessment of a significant subclavian stenotic lesion. Findings such as waveform dampening, monophasic waveform, flow reversal, color aliasing suggestive of turbulent flow, or increased velocities at the suspected site of stenosis are suggestive of significant obstruction. dence of obstruction or stenosis at a proximal site of the subclavian artery, (b) detection of vertebral arterial flow re-versal, and (c) demonstration of patent vertebral and subclavian arteries. Furthermore, asymptomaticpatients with retrograde vertebral arterial flow were diagnosed as having the subclavian steal phenomenon(25).
