Abstract

Introduction: vascular anatomy variations are important in academic, clinical and surgical areas as well as nephrology, urology, oncological and vascular surgery, among others. The main objective of this review is to know the real prevalence of multiple renal arteries in a wide, multiethnic population. Secondary objectives are to establish the prevalence of early branching of the renal artery and the prevalence of these variations in left and right kidneys. Methods: this study analyzes the renal arterial anatomy of 20.782 kidneys from 64 anatomical and radiological studies. Results: Multiple renal arteries (MRA) were present in 19,95% of the total kidneys, in number of 2 to 6 arteries arriving to the hilum. The most frequent number of MRA was 2 renal arteries (89,48%), followed by 3 (9,31%), 4 (1,06%), 5 (0,02%) and 6 (0,005%). This last one being found in only one kidney. Reported data on the lateralization of the MRA are rather poor, and among these no side’s predilection was found: MRA were found in 49,83% on the right side and 50,17% of left kidneys. Early branching patterns were described in only one third of the published data, being present in 11,4% of the total kidneys from those data (corresponding in 4,23% of right kidney cases and in 4,52% of left kidney cases; 2,66% had no right/left information). Discussion: the most difficult part was to merge the results from the different studies due to the heterogeneity of their descriptions. A universally accepted medical nomenclature is needed in order to allow a more precise lecture and transmission of results in clinical practice. Renal anatomical variations have clinical and surgical implications in renal transplantation, correctable hydronephrosis, ablation treatment for refractory hypertension or endovascular reconstructions and should be taken into account by every physician.

肾动脉变异:20.782例肾脏回顾。

引言：血管解剖变异在学术、临床和外科领域以及肾脏学、泌尿学、肿瘤学和血管外科等领域都很重要。这篇综述的主要目的是了解多支肾动脉在广泛、多民族人群中的真实患病率。次要目标是确定肾动脉早期分支的患病率以及这些变异在左肾和右肾中的患病率。方法：本研究分析了64项解剖学和放射学研究中20.782个肾脏的肾动脉解剖。结果：多支肾动脉（MRA）占总肾数的19,95%，其中2至6支到达肾门。MRA最常见的数目是2条肾动脉（89,48%），其次是3条（9,31%）、4条（1,06%）、5条（0,02%）和6条（0005%）。最后一个只在一个肾脏中发现。关于MRA偏侧的报道数据相当差，其中没有发现任何一侧的偏好：右侧肾的MRA发现率为49,83%，左侧肾的MRA出现率为50,17%。只有三分之一的已发表数据描述了早期分支模式，这些数据中有11.4%的肾脏存在早期分支模式（对应于4.23%的右肾病例和4.22%的左肾病例；2.66%没有右/左信息）。讨论：由于描述的异质性，最困难的部分是合并不同研究的结果。需要一个普遍接受的医学命名法，以便在临床实践中进行更精确的讲座和传递结果。肾脏解剖变异对肾移植、可纠正的肾积水、难治性高血压的消融治疗或血管内重建具有临床和外科意义，每个医生都应该考虑到这一点。

期刊介绍： The Italian Journal of Anatomy and Embryology, founded in 1901 by Giulio Chiarugi, Anatomist at Florence University, is a peer-reviewed journal sponsored by the Italian Society of Anatomy and Embryology. The journal publishes original papers, invited review articles, historical article, commentaries, obituitary, and book reviews. Its main focus is to understand anatomy through an analysis of structure, function, development and evolution. Priority will be given to studies of that clearly articulate their relevance to the anatomical community. Focal areas include: experimental studies, contributions based on molecular and cell biology and on the application of modern imaging techniques; comparative functional morphology; developmental biology; functional human anatomy; methodological innovations in anatomical research; significant advances in anatomical education. Studies that are essentially descriptive anatomy are appropriate only if they communicate clearly a broader functional or evolutionary significance. All papers should be submitted in English and must be original works that are unpublished and not under consideration by another journal. An international Editorial Board and reviewers from the anatomical disciplines guarantee a rapid review of your paper within two to three weeks after submission.
