“…CTA is a promising noninvasive method to evaluate carotid arteries, intracranial vessels, the aorta, the renal artery, and splanchnic and hepatic vessels. [1][2][3][4][5][6][7] Thoracic CTA has been used to evaluate pulmonary embolism, aortic dissection and aneurysm, pulmonary arteriovenous malformations, and stenosis and calcification at the origin of the VA. 4 There have been reports on false negatives of CTA in examination of intracranial aneurysm, carotid bifurcation, and hepatic artery. [12][13][14] To our knowledge, there has not been any reports on the use of CTA in the detection of SSS.…”

“…Computed tomography angiography (CTA) is a promising method to reliably and noninvasively evaluate intracranial and extracranial vessels, aorta, and peripheral vessels. [1][2][3][4][5][6][7] However, the reports on CTA in diagnosis of subclavian steal syndrome (SSS) is limited. This study attempted to compare the results among CTA, vertebral duplex ultrasonography and transcranial Doppler ultrasonography (TCD), and digital subtraction angiography (DSA) in the detection of SSS.…”

A patient presented with vertebrobasilar insufficiency during exertion. Vertebral duplex and transcranial Doppler ultrasonography showed reversal of flow in both intracranial and extracranial vertebral and basilar arteries, suggesting bilateral subclavian and vertebrobasilar steal. Electron beam computed tomography angiography (CTA) showed no evidence of subclavian artery stenosis including normal vertebral artery origin on both sides. However, digital subtraction angiography revealed complete occlusion of both subclavian arteries with retrograde flow from both vertebral and basilar arteries to reconstitute both subclavian arteries. This false-negative finding on CTA in detection of subclavian steal syndrome (SSS) is due to inappropriate contrast administration technique and postprocessing method, inability to differentiate flow direction, and lack of hemodynamic time sequences. This study demonstrates a pitfall of CTA in diagnosis of SSS compared to more reliable hemodynamic information obtained by duplex and transcranial Doppler ultrasonography, and digital subtraction angiography.

Ultrasound Investigation of Suspected Renal Artery Stenosis

Renal artery stenosis (RAS) is an important and potentially reversible cause of both hypertension and renal failure. Ultrasound offers an attractive, non-invasive, method to examine the renal arteries and confirm or exclude the presence of RAS. This article will describe the techniques and diagnostic criteria employed in the ultrasound diagnosis of this condition and will also evaluate the usefulness of ultrasound in comparison with other non-invasive imaging techniques.

“…Die Sensitivität der CT-Angiographie zur Detektion einer NAS liegt bei 96 % und die Spezifität bei 88 % [78,100]. Die CT-Angiographie ist indiziert bei besonderen Fragestellungen im Falle beidseitiger NAS oder bei akzessorischen Nierenarterien; etwas umstritten bei der FMD [35].…”

Hypertension is a frequent disease and renal artery stenosis, as a potential cause of hypertension, can be cured. Therefore, we frequently need to exclude a renal artery stenosis in patients with hypertension in our daily routine. This calls for a screening procedure which is non-invasive, highly effective and not too expensive. This paper describes the advantages and limitations of colour Doppler ultrasound in diagnosing renal artery stenosis. Colour Doppler ultrasound with intrarenal Doppler analysis is an ideal tool in the screening for relevant renal artery stenosis in patients with hypertension. This technique, however, requires a careful approach and extrarenal abnormalities need to be considered.
