Variation In Branch Free Length Of Renal Artery And Its Clinical Significans: A 64-slice Ct Angiographic Morphometric Study

ABSTRACT

Background: Length of renal artery is an important morphological parameter while performing surgeries in renalarea. The present study was conducted to evaluate variations in length of renal artery.Materials and Methods: The study was conducted in the department of anatomy and department of radiology ofKing George’s Medical University, Lucknow. 53 subjects (106 renal arteries), undergoing 64-slice CT angiographyfor different indications were included in the study group. The angiographic images of all the subjects in abdominalregion were analyzed for renal arteries and their length was measured utilizing computerized tools.Results: The length of main renal artery varied from 8.5mm to 54.8mm on the right side. On the left side minimumlength was 7.7mm and maximum length was 48.8mm. The average length of renal artery was 30.5±10.4 mm on theright side and 26.91±10.0 mm on the left side. There was great variation in the length of renal artery due tovariation in site of ramification.Conclusion: The variation of renal artery length is critically important for maintaining vascularity of kidney aftersurgery
