Résumé
The hila and adjacent pre-hilar parts of 72 kidneys (35 right and 37 left) isolated from formalin fixed cadaverswere examined. The hilum and prehilar area of each kidney was dissected to observe the total number ofbranches of the main renal artery. This information is useful in nephron sparing surgeries such as partialnephrectomy by laparoscopic approach. Subsequently, prehilar branching of the main renal artery before itenters the hilum was observed in 48.6% of kidneys with a higher incidence of 51.3% in left kidneys as comparedwith the incidence of the right side (45.7%). We further observe the variations of branching patterns in the mainrenal artery and calculate the incidences. Finally, our results are compared with that of similar studies conductedpreviously.
Résumé
Background: The two major changes that may occur in elderly individual without neurologic deficits is enlargement of ventricles and cortical atrophy. Aim of the study was to statistically analyse the dimensions of Fourth ventricle in humans and also to study the Changes that occur during ageing. Ventricular size of males and females was compared. METHOD: The CT images of 112 adult individuals (Age Group 21-60) and 88 ageing individuals (Age above 61) was studied in both males and females. Measurements like vertical length, height, anterior-posterior diameter and transverse diameter of fourth ventricle was made by using dicomworks software. RESULT: This study showed positive co-relation of age with dimensions of fourth ventricle and the dimensions of the fourth ventricle were enlarged with physiologic ageing. Also the dimensions of fourth ventricle were more in males as compared to females.
