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.
Sonography is the initial imaging examination when subclavian steal syndrome is suspected.

In the herein small series, the usefulness of a multimodality imaging approach including Doppler ultrasound, myocardial perfusion scintigraphy, and CT is well demonstrated. Asymptomatic subclavian stenosis does not require imaging or revascularisation, but does denote high cardiovascular risk warranting intensive risk factor reduction.

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.

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. 2018-04-17 · Arch aortography shows subclavian stenosis with antegrade vertebral flow in more minor subclavian stenosis. In progressive subclavian steno-occlusion, the filling of the vertebral artery becomes are superior to saphenous vein grafts.
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. 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 ).
