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-hundred fifty-two patients with suspected SAS were recruited into the study and examined from June 2005 to

are superior to saphenous vein grafts. If there is subclavian artery stenosis (SAS) proximal to the IMA graft, impairment of flow to the IMA may occur. If the stenosis is severe, retrograde flow from the grafted coronary artery to the brachial artery may lead to angina. Following the identification of 2 cases of

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. (C) In the short-axis view, the artery (A) and vein (V) are identified side by side. Compression with the transducer can be used to identify the artery and vein, because the vein is more easily compressed than the artery. The prevalence of subclavian artery stenosis is 2.5 to 4.5 percent in patients referred for coronary artery bypass grafting .

Subclavian stenosis imaging

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.

Subclavian stenosis imaging

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.

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 .

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

Asymptomatic subclavian stenosis does not require imaging or revascularisation, but does denote high cardiovascular risk warranting intensive risk factor reduction. Symptomatic subclavian stenosis can be successfully treated with percutaneous stenting.

We identified 165 patients with imaging-provenSSS from two hospitals. Demographic, clinical and imaging data were retrospectively collected. Patients were followed up for stroke events. Stroke occurred in 43 patients with a median follow-up of 28months. 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.
