“…Takebayashi et al also found that nutcracker syndrome can exist in either nondistended or distended LRV, and normal flow also can exist in distended LRV [15]. However, a combination of different parameters might improve the correlation with hematuria [10].…”

Effect of renal Doppler ultrasound on the detection of nutcracker syndrome in children with hematuria

et al. 2006

To assess the detection rate of nutcracker syndrome in children with isolated hematuria, renal Doppler ultrasound examinations were routinely performed on 216 consecutive children (176 microscopic hematuria and 40 gross hematuria). Renal Doppler ultrasound was also performed on 32 healthy normal children. The peak velocity (PV) was measured at the hilar portion of the left renal vein (LRV) and at the LRV between the aorta and the superior mesenteric artery. The PV at the aortomesenteric portion (P=0.003) and the PV ratios of the LRV (P=0.003) were significantly higher in children with hematuria than in normal children, while the PV at the hilar portion was not different. If a PV ratio of the LRV of at least 4.1 (the cut-off level set at the mean ±2 SD of the value for the normal children) was defined as abnormal, 72 cases (33.3%) in children with hematuria and no cases in normal children were diagnosed as having nutcracker syndrome. The prevalence of nutcracker syndrome is relatively high in children with isolated hematuria, and the inclusion of renal Doppler ultrasound as a screening examination has a substantial effect on the detection of nutcracker syndrome.

“…However, its compression in this area causes left renal vein hypertension, the nutcracker syndrome. The potential space between the aorta and the SMA, which is the course of the left renal vein, is about 4–5 mm . Retroperitoneal fat and the third segment of the duodenum provide a wide aortomesenteric angle here.…”

“…15 However, sonography is not considered the gold standard for nutcracker syndrome in adults, although it is often used as a tool for initial assessment ( Figure 5). In a study by Takebayashi et al, 6 a sensitivity of 78% and specificity of 100% were found using only sonography as a diagnostic method, leaving room for improvement for sonographic detection.…”

“…If the ratios of anterior-posterior measurements and peak venous flow velocities at these two locations exceed a factor of five, nutcracker syndrome should be suspected. 5,17 However, Takebayashi et al 6 concluded that measurements of the LRV may be inconclusive because of the potential presence of collateral venous flow. 1 It is thus appropriate that venous collateral vessels also be examined while attempting to determine the presence of nutcracker syndrome.…”

Nutcracker syndrome is a venous entrapment phenomenon characterized by the impingement of the left renal vein between the superior mesenteric artery and abdominal aorta. Treatment, if necessary, consists of surgical intervention. In the case presented, a young female presented at an outpatient vascular surgical center for surveillance of a surgically repaired nutcracker syndrome. A renal sonogram was performed to evaluate patency and hemodynamics of the left renal vein. Color and spectral Doppler were used to evaluate the left renal vein as well as the left kidney to document appropriate renal perfusion.
