Background: The purpose of this study is to evaluate the vascular and ureteric anomalies associated with ectopic kidneys with multidetector computed tomography (MDCT). Methods: The 40 patients with pre-diagnosed ectopic kidney undergoing MDCT urography (Contrast study) and KUB (Plain study) were included in this cross-sectional observational study. The location and number of bilateral kidneys were assessed. The number and origin of the renal arteries and renal veins were noted. Their relationship with each other and possible complications in surgical handling analysed. Data collected was analysed using descriptive and inferential statistics.Results: The renal artery originated from suprarenal aorta in 2 cases, normal origin in 10 cases, infrarenal aorta in 12 cases, aortic bifurcation in 19 cases, common iliac artery in 6 cases and iliac artery bifurcation in 2 cases. The renal vein was of normal origin in 8 cases, originated from infrarenal inferior vena cava (IVC) in 16 cases, IVC bifurcation in 14 cases, common iliac vein in 9 cases, internal iliac vein in 2 cases and external iliac vein in 1 case. There was a significant correlation between the level of ectopic kidneys (abdominal, iliac and pelvis) and level of origin of arteries (p<0.001) and veins (p<0.001). In addition, significant correlation was found between the origins of arteries and veins of ectopic kidneys (p<0.001).Conclusions: A knowledge of the possible variations in renal vasculature and ureter associated with ectopic kidneys can play a key role in preventing iatrogenic hemorrhage during surgery.
Background: Aim and objectives of the study were to radiologically evaluate paediatric patients with developmental delay (DD), assess the relative prevalence of abnormal brain MRI, further categorize them based on the abnormal imaging findings and structures affected. The purpose of this study is to diagnose the underlying etiology that helps in early treatment and amelioration of the condition, parental counselling regarding the outcome of the child, providing an estimate of child’s developmental potential and the recurrence risk in siblings.Methods: 135 paediatric patients of the age 3 months to 15 years with DD referred to department of radiology were investigated with MRI scans of the brain via 1.5T Siemens scanner after making the child sleep or sedated. The sequences used were: axial T1, axial T2, axial FLAIR, axial DWI, axial ADC, axial SWI, axial PHASE, sagittal T1 and coronal FLAIR. CT scan of the brain was done only when indicated on 128 slice Siemens Somatom perspective scanner. Informed consent shall be taken from patient’s parents. Clinical and demographic details of the enrolled patients were noted in the Performa. Data collected was analysed using descriptive and inferential statistics.Results: Out of 135 children with DD, 69.1% (n=92) were male and 31.9% (n=43) were female. Majority of these children belonged to 3 months to 1 year and 2 to 5 years of age group. About 81.4% (n=110) of children with DD had abnormal findings in MRI. Among children with abnormal MRI findings, 42.9% had hypoxic ischemic changes, 6.6% had congenital malformations and non-specific causes, respectively 4.4% had neurodegenerative and occlusive neurovascular conditions, respectively 3.7% had CSF disorders and neoplasms, respectively 2.9% had infection associated changes and non-traumatic intracranial bleed, respectively 2.2% had metabolic disorders and 0.7% had demyelination. Majority of cases had ventricular abnormality, followed by the corpus callosum.Conclusions: DD presents with a wide spectrum of etiologies, clinical findings and MRI features ranging from completely normal to abnormal. The present study could establish the various morphological appearances of DD on MRI and further categorize them into various subgroups be effective in diagnosis, management and prognosis determination processes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
