The aim of this study was to notice and describe the subsistence and occurrence of anatomical variations of the inferior mesenteric artery by Using imaging technique.Materials and Methods: 100 patients visited in the radiology department of S.M.S. Medical College Jaipur. To cover the whole abdominal arteria maxima in each patient, spiral CT angiography scan was made and thin slices (0.6 mm) axial images was obtained, Both sagittal and coronal images was reconstructed.Results: We found that 83% of patients presented a classic anatomy of the inferior mesenteric artery. Using this imaging technique; we found the existence of variations of these abdominal blood vessels in 17% of patients. Conclusion:The arterial variations should not be ignored and with an accurate knowledge on the anatomical variations, many operative and post operative complications can be avoided. The knowledge of the inferior mesenteric variations would enable the radiologists in protecting the impor-tant vessels prior to transcatheter therapies, and also in preventing inadvertent injuries.

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. KEY WORDS: Vessels, Renal Artery, Angiography, variations.

Introduction: The nerve to mylohyoid is a branch of inferior alveolar nerve which arises just above the mandibular foramen. There is occasionally communicating branch between nerve to mylohyoid and lingual nerve. Knowledge of such variations has significance during oral and submandibular surgery. Aim: To detect and describe the existence and occurrence of anatomical variations in the innervation pattern of the nerve to mylohyoid by using the dissection technique. Materials and Methods: An observational study was carried out from January 2022 to April 2022 in a total of 15 embalmed and formalin-fixed cadavers in the Laboratory of Anatomy of SMBT Medical College, Nashik, Maharashtra. The nerve to the mylohyoid and lingual nerve were cleared and observed for any unusual communication between the two, if any. Results: In 13 (86.67%) cadavers, classical (normal) anatomical presentation of the nerve to mylohyoid was observed, whereas, in two male (13.33%) cadavers, the presence of communicating branch between the nerve to mylohyoid and lingual nerve was observed. In both the cadavers, the communicating branch was unilateral, in one cadaver on the right-side, and in the second cadaver same variation was noted on the left-side. Conclusion: The existence of communication between the nerve to mylohyoid and the lingual nerve is thought to be responsible for inadequate mandibular anesthesia. Through this study, surgeons will be aware of this variance, to explain unexpected findings in nerve injury following oral procedures.
