Evaluation of Left Renal Vein Anatomy by Multidetector Computed Tomography
Keywords:
Renal vein. Inferior vena cava, Multidetector computed tomography, AngiographyAbstract
Prior to abdominal surgeries, particularly those included kidney transplant patients and donors and surgeries for aortic aneurysm, it is crucial to identify and well recognize the anatomy of left renal vein and its anatomical variation. Different diagnostic modalities are used for this purpose including radio imaging such as ultrasound, conventional computed tomography scanning and magnetic resonance imaging, however, multidetector computed tomography (MDCT) angiography has shown to be reliable and highly accurate diagnostic modality and become widely used as tool of choice by radiologists and widely recommended in diagnostic centers and it is currently preferred than conventional techniques. MDCT has shown as fast, minimally invasive and easily conducted examination providing detailed information with high accuracy in the evaluation of renal veins anatomy and variations. It provides significant information about the number, type diameter and course of renal veins. In Iraq, studies evaluating renal vein anatomy and renal arterial- venous malformations (AVMs) using MDCT angiography are scarce or unavailable. Given the clinical significance, there is a large demand to conduct a comprehensive evaluation due to importance of this topic to surgeons and scientific community and to support the surgical practice and research. This study aimed to investigate the frequency and percentage of types of left renal vein variants using MDCT angiography
