“…O termo que especifica as variações anatômicas renais é um dos pontos controversos na literatura, pela diversidade existente é recomendado 17 a terminologia proposta por autores nacionais 18,19 que utilizam as denominações artéria hilar, extra-hilar superior e inferior, polar superior e inferior e bifurcação precoce 17,13 , com descrição pormenorizada a seguir.…”

As variações anatômicas do tronco celíaco, artérias hepáticas e renais vêm sendo estudadas e documentadas ao longo dos anos. Representam relevância clinicocirúrgica, uma vez que podem resultar em diferentes dificuldades técnicas, sendo essencial seu relato a fim de se evitar danos vasculares e outras complicações operatórias. A angiotomografia computadorizada desempenha um papel importante, já que é um método de imagem rápido e eficaz, com menos complicações, relativamente, que a angiografia digital. Cabe ao radiologista correta avaliação diagnóstica, contribuindo com a redução de complicações e maior sucesso das intervenções terapêuticas. O presente ensaio iconográfico apresenta uma revisão de exames tomográficos de pacientes portadores de variações anatômicas do tronco celíaco, artérias hepáticas e renais, associada à descrição das imagens e classificações existentes.

“…Moreover, disparity between demands and supply is overgrowing in upcoming years (3) mainly because of increasing prevalence of ESRD. Anatomical variation of the kidney as a solid organ has a significant impact on surgical decision and transplant outcome; therefore, understanding the variations in the anatomy of the renal arteries is necessary (4).…”

The pattern of peri-hilar and hilar arterial branching in kidney allografts of living donors

et al. 2020

Introduction: Kidney transplantation gives us the opportunity to study kidney vascular anatomical variations and their probable effect on allograft survival. Objectives: The aim of this study was to evaluate the renal arteries’ branching patterns of the engrafted kidneys and their impact on transplant outcomes. Patients and Methods: Three hundred patients who received kidney transplantation between 2014 -2017 were included. Peri-hilar and hilar branching patterns of the engrafted kidney were studied by reviewing the archived CT angiographies of donors and then they categorized based on the existing knowledge in this field. Clinical data were also gathered from medical records and recipients’ latest clinical and laboratory evaluations. Results: Based on peri-hilar and their corresponding hilar branching patterns, our morphology findings were classified into 17 groups. From different peri-hilar branching patterns, the fork pattern was more common which is detected in 95% (242) while the ladder pattern was observed in 5% (13) of kidney grafts. In a later branching sub-categorization, among the fork pattern, 65.2% (158) were duplicated and 34.7% (84) had triplicated hilar branching patterns. There was not a statistically significant correlation between each of those patterns and allograft function (P > 0.05). Conclusion: Peri-hilar and hilar branching patterns of the kidney allografts’ renal artery were different, but they follow certain patterns. Although it may not influence the allograft survival, it provides us precise knowledge about renal vasculature patterns and outcome of probable vascular events meanwhile; it could be useful in the field of transplantation.

“…Congenital anomalies of the urinary tract have been the object of recent studies in the radiology literature of Brazil 1 - 3 . A supernumerary kidney is a rare congenital anomaly of the urinary tract, fewer than 100 cases having been documented in the literature, with no difference between the genders and preferential occurrence on the left side.…”
