A computed tomography angiography study to correlate main renal artery diameter with presence of accessory renal artery in healthy live kidney donors

Background: The abdominal aorta and its main branches, such as the celiac trunk and the renal arteries are manipulated during various radiologic, surgical, and oncologic procedures. This study aimed at evaluating the anatomical pattern of these vessels to assist surgeons and radiologists reduce the risk of intra- as well as postoperative complications. Methods: A retrospective analysis of 536 Computed Tomography Angiography (CTA) studies of living potential kidney donors was conducted from January 2012 to December 2018. Results: The anatomical variations of the celiac trunk was found in 9.5% of the cases. Among these cases, the most frequent variation was the Left Gastric Artery (LGA) as the first branch of the celiac trunk (80.4% of the cases). Gender was not overall significantly associated with the variations of the celiac trunk (P=0.670); however, there was a significant correlation between male gender and the most prevalent form of the celiac trunk variation (P=0.004). Variations of the renal artery occurred in 22.94% of the cases, with the left accessory renal artery being the most common variant (28.45% of the cases). Gender and the involved side (right/left) were not significantly related to the renal artery variations (P=1.000 & P=0.546, respectively). No concomitant variation of the celiac trunk and the renal artery was detected in our study. Conclusion: The anatomical variations of the celiac trunk and the renal arteries occur commonly; thus, the branching pattern of these arteries should be assessed prior to any procedure concerning them.

Collateral System

The renal artery when it reaches close to the hilum of kidney where it cleaves into anterior and posterior divisions were receives around 75% and 25% of blood respectively. Further these branches divide into many segmental branches. These segmental arteries does not have collateral system, so when there is any occlusion of these arteries which results in the ischemia of the particular segment of kidney. Anatomists believe that knowledge of presence of lower polar artery is essential for polar nephrectomy. Prior knowledge of variations in the renal vessels is required for urological surgery for preoperative investigations as there are reports of surgical complications which include enormus haemorrhage. In this study we analyzed the different variations in the intra renal branch of inferior segmental artery.

Variant Anatomy

The article discusses variant anatomy of the renal arteries, potentials of three-dimensional modeling and use of these data in clinical practice. Despite a large number of studies based on both morphological and clinical approaches there is no general consensus regarding options for dividing the renal artery, the number of its branches, their topolocalization. This is due to the fact that most of the research studies are based on cadaveric material, fixed and unfixed. It is difficult to apply these data to explain medical conditions and pathologies of particular patients. Computed tomography allows performing in vivo investigation of various morphometric parameters of the renal arteries, and these findings can subsequently be used in disease diagnostics and treatment.The aim of the study was to identify patterns of topography, linear dimensions and variant anatomy of the human renal arteries based on computed tomography angiography (CTA) with three-dimensional modeling, and to apply CTA findings in clinical practice.Material and methods. The study included CTA images of the abdomen of 130 patients, and their threedimensional models. A hardware-software complex "Luch-S" and software complex "Avtoplan" (Russian project) were used to perform morphometric analysis. The diameter of the renal artery mouth, the level of origin of the renal artery mouths, as well as the angles between the renal arteries and the abdominal aorta were analyzed morphometrically and statistically.Results. The authors have developed recommendations how to use three-dimensional modeling of vascular- organ complexes in patients at the stage of preoperative planning and intraoperative navigation in clinical practice. Generated dataset of personalized morphometric data can be applied to teach basic operation techniques involving possible damage to abnormal vessels, as well as training specific surgical procedures involving the kidney and its vessels in a simulation-based surgical clinic.
