ABSTRACT
Abstracts: Background: Sound knowledge of left coronary artery (LCA) is necessary for performing coronary angiographies and shunt surgeries. Study of origin, course of left coronary artery and its branches helps in judging the area of myocardium supplied by them which in turn helps in judging the size of infarct. Methodology: The present study is done on 76 adult heart specimens obtained from routine dissection conducted for undergraduate students in the Department of Anatomy at Bidar Institute of Medical Sciences, Bidar and also at other nearby medical colleges of Karnataka and Maharashtra. The data obtained is tabulated and analyzed statistically. Results: In our study, in all the cases the Left coronary artery originates from left posterior aortic sinus. Bifurcation of left coronary artery is seen in 81.5%, trifurcation in 14.5% and quadrifurcation in 4% cases. The left anterior descending artery (LAD) terminates by wrapping around apex in 70% cases and the left circumflex artery (LCX) terminates between obtuse border and crux of heart in 52.5% of cases. Conclusion: The present study is done to know origin, distribution, branching and level of termination of left coronary artery in adult human hearts of Hyderabad Karnataka region to provide vital inputs for making a correct diagnosis and planning treatment for procedures like coronary angiography, stenting procedures and surgical myocardial revascularization in extensive myocardial ischemia.
ABSTRACT
Background and objectives: Coronary artery anomalies are known to be associated with congenital heart defects, myocardial ischemia and reduced life expectancy. The sound knowledge of coronary artery anatomy is necessary for proper management of patients undergoing evaluation for percutaneous coronary intervention, coronary artery surgery or prosthetic valve replacement. The present study is done to determine the origin, course and variation of right marginal artery for proper diagnosis and treatment of the heart diseases. Materials and Methods: The present study is done on 76 adult heart specimens obtained from routine dissection conducted for undergraduate students in the Department of Anatomy at Bidar Institute of Medical Sciences, Bidar and also from other nearby medical colleges of Karnataka and Maharashtra. The data obtained is tabulated and analysed statically. Results: In our study it is observed that the right marginal artery is present in 88% cases and is absent in 12% cases. Right marginal artery terminates before inferior border in 19%, in between inferior border and apex in 78%, and in 3% cases right marginal artery terminates at apex. Conclusion: The present study is done to know the normal and variant anatomy of right marginal artery in Hyderabad Karnataka region to provide vital inputs for making a correct diagnosis and planning treatment for procedures like coronary angiography, stenting procedures and surgical myocardial revascularization as the right marginal artery terminating at apex can irrigate the inferior third of heart, diaphragmatic area limiting the possibility of ischemic process in the occlusion of anterior interventricular artery.
ABSTRACT
In our present case the axillary nerve on both sideswas arising from posterior cord. About 2.5cm fromits origin at the lateral border of subscapularis, it gave 2 branches i.e anterior and posterior branch. The axillary nerve branched before entering the quadrangular space. Knowledge of the precise relationship of the branches of the axillary nerve, its relationship to the shoulder capsule and its common variations within deltoid muscle is necessary for performing surgical procedures over shoulder and reduce the incidence of iatrogenic nerve damage.
