CT- ANGIOGRAPHY BASED STUDY OF VARIATIONS IN BRANCHING PATTERN OF RENAL ARTERY

Objective: The purpose of the present study is to search and detailed the existence and occurrence of anatomical variations of the renal artery by using CT angiography. Materials and Methods: 100 patients visited the Radiology department of S.M.S. Medical College, Jaipur. To cover the whole abdominal aorta in each patient, spiral CT angiography scan was made and thin slices (0.6 mm) axial images was obtained. Both sagittal and coronal images were reconstructed. Results: We found that only 23% patients had classical (Normal) anatomical presentation of Renal artery, whereas in 77% patients, variations existed in the same, using CT angiography method. Conclusion: The different varieties of renal vessels have been experienced with expanding recurrence over past decade. This is because of wide spread utilization of renal angiography and other imaging modalities, as of late. We as anatomist accept that anatomical information on atypical renal courses is significant for all careful and radiological intercessions including the kidneys or it might prompt mistaken translation.
