Unusual subclavian steal: bidirectional and antegrade blood flow in the vertebral artery

We present an unusual radiographic manifestation of subclavian steal seen in six patients. These cases differ from the classic form of subclavian steal in that antegrade and bidirectional blood flow in the vertebral-subclavian antery system in seen, resulting in the steal phenomenon.

SPECT evaluation of cerebral blood flow during arm exercise in patients with subclavian steal

Objectives To explore the cerebral hemodynamics in subclavian steal syndrome, we examined the cerebral perfusion of seven patients with subclavian steal (one symptomatic and six asymptomatic) using single-photon emission computed tomography (SPECT) during resting, arm exercise, and acetazolamide-activated conditions. Methods The regional CBF (rCBF) was measured with SPECT under all conditions, and region of interest (ROI) analysis was performed using a three-dimensional stereotaxic ROI template (3DSRT). We evaluated the relationship between arm exercise-induced rCBF change and (1) presence of subclavian artery stenosis, (2) vertebral reverse flow severity, (3) presence of vertebro-basilar insufficiency (VBI) symptoms, and (4) cerebrovascular reactivity (CVR) to acetazolamide. Results Overall, no arm exercise-induced rCBF reduction was observed on either the affected or the unaffected side, even in patients with severe vertebral reverse flow. One patient with VBI symptoms showed an arm exercise-induced global rCBF reduction in the cerebrum and cerebellum, whereas the other asymptomatic patients did not. The %rCBF changes in segments with severely impaired CVR (−8.6%± 10.7%, mean ± SD) were significantly lower than those in other segments with less impaired CVR (P < 0.01). Conclusions Our results suggest that subclavian steal is a benign condition in asymptomatic patients. On the other hand, arm exercise-induced rCBF reduction can occur in the cerebrum and cerebellum in patients with VBI symptoms possibly related to low CVR.     

Right aortic arch with isolation of the left innominate artery

Isolation of the left innominate artery and right aortic arch, a rare variant of right aortic arch anomalies, was diagnosed in a four-year-old boy with other congenital cardiac anomalies. Isolation of vessels from the aortic arch is predicted from the primitive double aortic arch model of Edwards. In this patient there was no evidence of a vascular ring or of a significant subclavian steal syndrome.     

Colour doppler imaging of partial subclavian steal syndrome

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 arm exercise. Angiography confirmed a highgrade stenosis of the proximal subclavian artery and balloon angioplasty was performed. Nonivasive follow-up by CDI demonstrated regular antegrade vertebral artery flow at rest, but minimal retrograde systolic flow after left arm exercise.     

Subclavian atherectomy and angioplasty for coronary subclavian steal syndrome post CABG

Coronary subclavian steal syndrome is an uncommon complication occurring in patients with coronary artery bypass graft (CABG). We describe a case of a 69-year-old male with a remote history of CABG who presented with exertional left arm pain and angina. Computed Tomographic Angiography of the chest demonstrated a severe left proximal subclavian artery stenosis. The case demonstrates successful application of subclavian atherectomy with use of embolic protective device, alleviating the need of stent, for treatment of Coronary subclavian steal syndrome in patient with remote history of CABG.     

Right-side aortic arch with aneurysm of aberrant left subclavian artery: MR imaging appearance.

Reports of aneurysms of the subclavian artery in both normal and anomalous aortic arches have been rare. The authors describe a patient with a right-side aortic arch and an aneurysm of the aberrant left subclavian artery, which, to the authors' knowledge, is a previously unreported association. At presentation, the aneurysm appeared as a calcified left superior mediastinal mass. Magnetic resonance imaging enabled preoperative diagnosis and guided surgical planning.     

Double aortic arch: An orifice projection using angled cineangiography

Double aortic arches are usually shown angiographically by an injection of contrast in the aortic root with filming in the frontal (PA) and lateral projections. This is not completely satisfactory, however, as superimposition may mask the site of an associated atresia, which dictates the point at which the narrower arch should be divided. An angled view of the orifice of the ring, obtained in a six-week-old boy, showed the complete anatomy of the malformation.     

锁骨下动脉窃血综合征的彩色多普勒超声与CTA的对比研究

目的探讨锁骨下动脉窃血综合征的彩色多普勒超声与CTA特征及诊断价值。方法回顾性分析2l例锁骨下动脉(subclavian artery,SCA)窃血综合征患者的超声及CTA资料,并进行对照分析。结果锁骨下窃血综合征发生于左侧病变l4例,右侧7例,其中部分窃血6例,完全窃血14例,其中锁骨下动脉起始部闭塞5例。患侧椎动脉反向程度与该侧锁骨下动脉或无名动脉狭窄程度与CTA对照呈正相关。结论椎动脉反流是诊断锁骨下动脉窃血综合征的重要依据之一,也是超声多普勒诊断锁骨下动脉窃血综合征的优势。锁骨下动脉管腔的真实狭窄程度CTA具有绝对的优势。     

经颅多普勒与彩色多普勒超声对锁骨下动脉盗血综合征的诊断价值

目的:探讨经颅多普勒(TCD)与彩色多普勒超声对锁骨下动脉盗血综合征(SSS)的诊断价值。方法:应用彩色多普勒超声检测32例SSS患者的椎动脉颅外段、颈动脉、锁骨下动脉(SubA)、无名动脉的彩色血流形态,内-中膜厚度及狭窄程度;TCD检测椎动脉颅内段与基底动脉血流方向及频谱的改变。结果:32例中SubA中度狭窄11例,重度狭窄12例,闭塞9例。TCD检查Ⅰ期盗血11例(34%);Ⅱ期盗血11例(34%);Ⅲ期盗血10例(32%)。结论:彩色多普勒超声与TCD联合应用,通过对SubA及无名动脉的内-中膜厚度、狭窄程度及椎-基底动脉频谱形态的测量,有利于对SSS病因及程度的诊断。     

Bilateral subclavian steal syndrome: Treatment with percutaneous transluminal angioplasty and stent placement

A 66-year-old man presented with bilateral subclavian steal syndrome (SSS) due to proximal subclavian artery occlusions. He was treated by percutaneous transluminal balloon angioplasty (PTA) and stent implantation in the left subclavian artery and by PTA alone in the right subclavian artery. We could demonstrate that interventional treatment of symptomatic bilateral SSS is possible. If PTA alone is insufficient, stent implantation should be considered.
