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. 11,12 Subclavian steal phenomenon is associated with specific vertebral artery waveforms.

Two-hundred fifty-two patients with suspected SAS were recruited into the study and examined from June 2005 to December 2009. Duplex sonographic examination is one of the best modalities for the diagnosis of stenoses and other diseases of the carotid, vertebral, and subclavian arteries. If abnormal Doppler waveforms in the VA are found, duplex interrogation of both SAs should be performed (even if a SA scan is not a part of your routine protocol). With head and neck coils and high-gradient MRI technology, gadolinium-enhanced MRA enables accurate depiction of proximal subclavian artery steno-occlusive disease.

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.

Spinal stenosis is a condition characterized by the narrowing of the spaces in the spinal cord. This condition creates pressure on the nerves along the spinal column. There are two types of spinal stenosis that can be distinguished by where

Intracranially, the bilateral vertebral arteries join to form the basilar artery and terminates in the right and left posterior cerebral arteries (PCA). 2016-03-01 · Residual stenosis of the subclavian-axillary vein is not uncommon following decompression due to fibrous strictures or thrombus; options for management include intraoperative or postoperative venography and angioplasty with or without stent insertion, vein patching, mechanical thrombectomy, or axillary-subclavian vein reconstruction. In CSSS, subclavian angiography is the standard diagnostic test. However, other diagnostic techniques may be valuable to better clarify this challenging diagnosis.

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

We present two cases of subclavian steel syndrome to give an impression of the wide spectrum of possible symptoms and of the commonly used imaging modalities in subclavian steal syndrome.

When sonography is limited, such as for the evaluation of subclavian disease, CT or MRI can be used to evaluate the anatomy.

Information about symptoms, health and lifestyle habits will help determine the type of arth Spinal Stenosis is a disorder that is triggered by the pressure on the spinal cord and its nerves. The disease makes the spinal canal narrow and results in back pain, nerve problems, and sciatica. Most people have pain in their lower back a Spinal stenosis causes narrowing in your spine which puts pressure on your nerves and spinal chord. It can cause pain, numbness, and foot problems.

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.

We report three cases of symptomatic stenosis of the great vessels or supra-aortic trunks successfully treated surgically with aorto-subclavian and aorto-innominate bypass. 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
