1806 PART V Pediatric SonographyABCDEFGFIG. 52.45 Renal Artery Stenosis in a 4-Year-Old Boy With Midaortic Syndrome and Hypertension. (A) and (B) Longitudinal gray-scaleand color Doppler images of the abdominal aorta show focal marked mural thickening and signiicant luminal narrowing as well as color aliasing atthe site of stenosis (arrows). (C) and (D) Spectral Doppler display reveals an elevated peak systolic velocity within the aorta at the site of narrowing(C) compared with the peak systolic velocity within a more proximal portion of the aorta (D). Peak systolic velocity within the proximal right mainrenal artery is elevated (E) compared with the velocity obtained from a more distal portion of the artery (F). The distal artery also demonstrates adelayed systolic upstroke with diminished amplitude and rounding of the systolic peak (tardus-parvus waveform). (G) A similar tardus-parvus spectralDoppler waveform is obtained from the interlobar vessels of the right kidney.
CHAPTER 52 The Pediatric Urinary Tract and Adrenal Glands 1807ABFIG. 52.46 Hemolytic-Uremic Syndrome in a 6-Year-Old Girl. (A) Longitudinal image reveals increased right renal cortical echogenicity,greater than that of the adjacent liver (L). (B) Spectral Doppler display reveals diminished diastolic blood low with an elevated resistive index in aright renal interlobar artery.RENAL TRANSPLANTATIONRenal transplantation is the treatment of choice for end-stagekidney disease in children. Gray-scale and color Doppler ultrasoundimaging provide a comprehensive assessment of transplantmorphology, depiction of perirenal and pelvic luid collections,and evaluation of grat vascularity. At our hospital, an initialpostoperative ultrasound examination is performed with shorttermfollow-up studies performed as clinically indicated. Longtermfollow-up consists of yearly ultrasound studies. Ultrasoundis also used to guide allograt biopsy.Approximately half of all renal transplants in children areobtained from living donors, usually a parent. 119,120 In olderchildren, surgical technique is identical to that used in adults,with the allograt placed in an extraperitoneal location in theright or let iliac fossa, and end-to-side vascular anastomoses tothe ipsilateral external iliac artery and vein. If there is a signiicantsize discrepancy between the donor and an infant or small childrecipient, the allograt may be placed intraperitoneally, with anend-to-side anastomosis of the transplant renal artery to theaorta and of the transplant renal vein to the inferior vena cava,in order to optimize grat perfusion.Ultrasound evaluation of a normal renal allograt demonstratesan intraabdominal or intrapelvic kidney with gray-scale andDoppler imaging features identical to those of a native kidney.Immediately postoperatively, moderately elevated peak systolicvelocity and turbulent low in the main renal artery are commonand probably related to edema at the arterial anastomosis withfunctional narrowing. Associated diminished downstream peaksystolic velocities can result in diminished arterial RIs at thelevel of the interlobar arteries. Conversely, elevated arterial RIscan occur as a result of difuse grat edema and diminisheddiastolic low. hese abnormalities oten improve or normalizewithin in the irst 24 hours ater transplantation. 121 Recently,CEUS has been used to provide both qualitative and quantitativeassessment of renal allograt blood low and perfusion. CEUShas been shown to be superior to conventional ultrasound incombination with Doppler imaging in detecting even subtlemicrovascular disturbances in allograt perfusion. In addition,quantitative perfusion parameters derived from CEUS showpredictive capability regarding long-term kidney function. 122,123To date, there is limited experience in the use of CEUS forevaluation of renal allograts in the United States.Vascular ComplicationsVascular complications occur in 0.8% to 13.9% of pediatric renaltransplants, 124,125 and include renal artery thrombosis, renal veinthrombosis, renal artery stenosis, AVF, and arterial pseudoaneurysm.Children are at increased risk of early vascular thrombosiscompared with adults because of their small size and frequentdiscrepancies between the size of the donor and recipient vessels. 126According to data from the North American Pediatric RenalTransplant Cooperative Study, grat thrombosis is the mostcommon cause of irst-year allograt loss in children, accountingfor as many as 35% of cases. 127 Sonographic assessment of thetransplanted pediatric kidney is an important and useful tool inthe detection of early vascular complications. 121Renal artery thrombosis with associated grat infarctionis an unusual complication of renal transplantation, occurringin only 3% to 4% of all pediatric renal transplants. 128,129 It usuallydevelops within the irst 48 hours ater transplantation and isassociated with en bloc transplants from young cadaveric donorsthat contain paired renal allograts as well as the ureters, mainrenal arteries and veins, and segments of the juxtarenal aortaand inferior vena cava. Most cases are related to arterial kinkingor intimal dissection (Fig. 52.47). Segmental infarctions sometimesoccur in the early postoperative period in allograts with multiplerenal arteries, but these lesions more commonly develop as alate complication in association with acute or chronic rejection 130(Fig. 52.48). Clinical symptoms of infarction include tenderness
