“…We believe the increased velocity to be attributable to the tortuosity of the measured ICA. Indeed, vessel tortuosity producing falsely elevated velocities increases the false-positive rate for stenosis on Doppler ultrasound [12], [17]. The color Doppler presented here (ICA) is devoid of color aliasing and color bruit artifact in surrounding tissue which are further signs of high grade stenosis [12].…”

Congenitally absent internal carotid artery with intercavernous anastomosis is an exceedingly rare vascular anomaly. We report such a case in a 65-year-old man with chronic symptoms resembling sporadic transient ischemic attacks. While these patients are usually asymptomatic due to compensatory collateralization, they are at increased risk of aneurysm formation, and thus proper identification is important. This report serves as both a case of a very rare anomaly and as a lesson on how to avoid this misdiagnosis by carotid duplex sonography. Additionally, we review the limited number of published cases of congenitally absent internal carotid artery with intercavernous anastomosis.

Background: Duplex ultrasound (DUS) is a well-tolerated, noninvasive imaging technique. Renal artery stenosis (RAS)—a narrowing of the arteries that supply the kidney—is involved in the cause of renal failure, and its gold-standard method of detection is digital subtraction angiography (DSA). Whether DUS is a suitable alternative to DSA or other angiographic modalities has only been reviewed up to 2005, producing mixed results with studies based on older ultrasound technology without a measurement of study quality. Purpose: To provide an up-to-date review of the diagnostic accuracy of DUS for the diagnosis of RAS in comparison with angiography. Methods: Our registered systematic review (DOI: 10.17605/OSF.IO/SE9VN) examined articles post-2005. Studies must have compared RAS diagnosis between DUS and angiography. Sources were searched in November 2022 and included Scopus, EMBASE, MEDLINE, CINAHL, and Academic Search Premier (1749 citations; final: n = 34; DSA only: n = 9). Study quality was assessed using the Quality Assessment of Diagnostic Studies 2 tool and results are presented narratively. A total of 2968 (1281 females) patients were included. Duplex ultrasound exhibited moderately high agreement with DSA and other well-established angiographic criteria with the existing literature having low risk of bias and low concern for patient applicability. Studies exhibiting low agreement were generally in smaller samples or used unique definitions of stenosis. Conclusions: Improved study reporting, consistent definitions of stenosis, and a common statistical battery are needed.

“…Esse grupo de estudo sugere a realização do corte coronal de forma rotineira, como uma técnica adicional aos cortes transverso e longitudinal. 153,161,162 Deve-se salientar que o diagnóstico da EAR é feito principalmente pela avaliação direta, com a visualização das artérias renais em suas origens e, sempre que possível, em toda a sua extensão. Devem-se utilizar a imagem bidimensional e o mapeamento de fluxo em cores, com aquisição da velocidade de pico sistólico (VPS) e da velocidade diastólica final (VDF), que devem ser interrogadas também em qualquer ponto que sugira elevação da velocidade pelo Doppler colorido.…”
