Key result
Asymptomatic nutcracker syndrome links to ~28% higher left renal vein peak velocity ratios than symptomatic cases.
Why the study?
Are Doppler ultrasonographic indices of the left renal vein associated with the pattern of symptoms in pediatric patients with nutcracker syndrome?
Population
44 pediatric patients diagnosed with nutcracker syndrome (NCS) between January 2008 and December 2015
Comparison
Left renal vein Doppler ultrasonography (DUS) vs Symptomatic versus non-symptomatic patients
Design
Cohort

Higher left renal vein ratios in asymptomatic children warrant caution against symptom correlation; leaves open Doppler utility for risk stratification in nutcracker syndrome.

Are Doppler ultrasonographic indices of the left renal vein associated with the pattern of symptoms in pediatric patients with nutcracker syndrome?
Absolute Event Rate: 7.99% vs 6.22%
p-value: p=0.035
Increased compression ratio of the left renal vein entrapment on Doppler ultrasonography is most observed in pediatric patients with orthostatic proteinuria and microscopic hematuria (asymptomatic nutcracker syndrome).
Nalçacıoğlu et al. (2018) conducted an observational in Nutcracker syndrome (n=44). Asymptomatic presentation (microscopic hematuria and proteinuria) vs. Symptomatic presentation (loin pain, macroscopic hematuria) was evaluated on Peak velocity ratio of the left renal vein between the aortomesenteric and hilar portions (p=0.035). Asymptomatic children with nutcracker syndrome had significantly higher peak velocity ratios (7.99 vs 6.22, p=0.035) and diameter ratios (4.79 vs 3.69, p=0.025) of the left renal vein compared to symptomatic patients.
