ABSTRACT
Introduction: Knowledge of the normal liver morphology and its variants important in the era of diagnostic imaging and minimally-invasive surgical approaches. Method: 50 formalin-fixed livers were utilised for the study. Studied liver classified according to morphological types. Result: Normal liver found in 48% cases. Remaining 52% cases found variations out of that 28% cases found liver with lingular process and 12% cases found liver with diaphragmatic surfaces. Costal liver with very small left lobe and deep impressions in 6% cases,2% cases of Liver with total atrophy of the left lobe,2% cases of Liver with deep renal impressions and “corset” type constriction and 2% cases of Liver with right lobe very much smaller than the left. Conclusion: Our study highlights variations in liver morphology ,knowledge of these important for surgeon and radiologist.
ABSTRACT
Introduction:-Variation in origin, branching pattern, course and termination of musculocutaneous nerve are common. These anatomical variations important for anatomist, clinicians, anaesthetics and surgeons for avoid unexpected complication. Material & method:- Detailed study of 50 upper limbs of cadavers carried out in last 3 year. Result –in this study 4% cases there is absence of musculocutaneous nerve. Musculocutaneous nerve not piercing coracobrachialis and communicate with median nerve in 4% cases and musculocutaneous nerve rejoins with median nerve in 2% cases. Conclusion:- In this study we found significant variation in musculocutaneous nerve which is important for surgeons, while planning surgery in axilla and arm to avoid injury.
ABSTRACT
Introduction: A study of placental vasculature pattern was undertaken by using corrosion cast technique. The placenta is a highly vascularised organ. In this study we aimed to elucidate the structure of the cotyledonary vasculature of the human placenta after delivery, which serves as a core for the shape of the whole foetal villosity. Material & Method: Appropriate cast material was injected through placental vessels to form a corrosion cast model of placental blood vessels which was followed by meticulous dissection. Results: The cast models demonstrated very well the Hyrtl anastomosis between the umbilical arteries in the vicinity of the umbilical cord insertion into the placenta but no extra-placental anastomosis found between umbilical artery and umbilical vein. The chorionic vasculature exhibits a combination of the dichotomous and monopodial patterns. The chorionic vessels branch through 6 to 8 generations from the cord insertion towards the margins of the chorionic plate. The vein bifurcated twice immediately after insertion into the placenta. Conclusion: 3-dimensional structure of placenta can be demonstrated by micro vascular casts which reflect the shape of the whole or part of the organ, and include specific details such as the capillary architectural structure. Macroscopic visualisation can technically be advanced in 3 ways: treatment of maternal and fetal circulatory systems in common or each of the 2 systems separately.
