“…Multidetector scanners have advanced the imaging clarity in computed tomography, making it possible to visualize vascular structures in detail. Multidetector computed tomography (MDCT) is a reliable and noninvasive tool for diagnosing renal artery variations and pathologies [4] . We present a case of a rare arterial variation in whom the renal artery arose from the inferior mesenteric artery (IMA) and common iliac artery (CIA).…”

Objective: To present a case of a rare variation of the renal artery and multiple (7) renal arteries by multidetector computed tomography (MDCT) angiography. Clinical Presentation and Intervention: A 36-year-old male patient was admitted to our hospital as a potential living donor for renal transplantation. An MDCT angiography was performed using a 16-detector row CT scanner to obtain a detailed image of vascular structures and associated pathologies. The MDCT clearly revealed the presence of 3 right and 2 left renal arteries arising from the abdominal aorta. Additionally, the accessory renal artery arose from the inferior mesenteric artery on the left side and from the common iliac artery on the right side. Conclusion: This case highlights the importance of awareness of renal artery variations if surgical procedures are indicated in this region.

“…Another complicating factor in this study is the use of differing imaging modalities for each study cohort for determining the presence of FMD (CTA versus catheter-based angiography). However, several prior studies [21][22][23] have shown that CTA is a reliable diagnostic modality for detecting renal atherosclerotic and FMD lesions. A recent study 23 demonstrated that CTA detected 100% of the 40 FMD lesions that were detected by catheter-based angiography in a population of 21 hypertensive FMD patients.…”

Is fibromuscular dysplasia underdiagnosed? A comparison of the prevalence of FMD seen in CORAL trial participants versus a single institution population of renal donor candidates

Renal artery fibromuscular dysplasia (FMD) may be underdiagnosed. We evaluated the prevalence of FMD in CORAL (Cardiovascular Outcomes in Renal Atherosclerotic Lesions) renal artery stent trial participants, in which FMD was an exclusion criterion for inclusion. We also evaluated the prevalence of FMD in a relatively healthy population of patients undergoing computed tomographic angiographic (CTA) screening for renal donor evaluation. All renal donor CTAs performed at our institution from January 2003 through November 2011 were retrospectively reviewed for the presence of FMD along with patient sex and age. These results were compared to angiographic core lab (ACL) findings for the CORAL trial. The CORAL ACL database contained 997 patients (mean age 69.3 years; 50% female). Fifty-eight (5.8%) CORAL trial patients (mean age 71.8 years; 75.9% female) demonstrated incidental FMD. The renal donor cohort included 220 patients (mean age 40.5 years; 64.5% female). Five (2.3%) demonstrated FMD (mean age 48.6 years; all female). The odds of FMD in the CORAL cohort were 2.65 times that seen in the renal donor cohort (95% CI: 1.12, 7.57). In conclusion, the 5.8% prevalence of renal artery FMD in the CORAL trial population, the presence of which was biased against, suggests underdiagnosis.

“…Arteriosklerotische Wandveränderungen und Stenosierungen treten dabei bevorzugt am Abgang und innerhalb der ersten 2 cm der Nierenarterien auf [27] und sind durch die MDCT-Angiographie gut darstellbar. Die diagnostische Wertigkeit der MDCT-Angiographie reicht bei adäquater Untersuchungstechnik an die der konventionellen Angiographie heran [9]. Zunehmend gewinnt auch die MR-Angiographie an Bedeutung.…”

Multidetector computed tomography (MDCT) for renal and hypertonic diseases

et al. 2008

Die Computertomographie (CT) hat sich seit Einführung der Einschicht-CT vor mehr als 30 Jahren zunehmend weiterentwickelt: Eckpunkte sind die Entwicklung der Spiral-CT und die Einführung der Multidetektortechnik. Die Spiral-CT ermögli-cht eine kontinuierliche Datenakquisition, während der Patient durch den Tomographen bewegt wird. Die Multidetektor-CT (MDCT) führt zu einer deutlichen Erhöhung der Akquisitionsgeschwindigkeit und der longitudinalen Auflösung [8]. Durch die technische Weiterentwicklung haben sich die Anwendungsmöglichkeiten der CT erweitert, was auch Einfluss auf die Bildgebung bei Nieren-und Hochdruckerkrankungen hat.

Multidetector–row CT angiography of renal artery stenosis in 50 consecutive patients: prospective interobserver comparison with DSA

Abstract: MDCT angiography is very accurate and robust, even for the assessment of renal artery stenosis, and has the potential to become a viable substitute, in most cases, for diagnostic catheter-based DSA.
