Study of anatomical variation of right and left hepatic arteries.

The morphological study was done to see the origin of right and left hepatic arteries supplying the liver and gallbladder in Bangladeshi people to increase the knowledge regarding variational anatomy in this region. Sixty post mortem tissue blocks containing liver and gallbladder along with surrounding structures were collected from 40 male and 20 female cadavers of different age groups and fixed in 10% formol saline solution. This was a cross sectional descriptive study. This study was carried out in the Department of Anatomy in Mymensingh Medical College, Mymensingh, from July 2007 to June 2008. Gross and fine dissections were carried out to study the different origin of right and left hepatic artery and its topographic relationship with adjacent structures. In the present study, findings were compared with the findings of Western researchers. In the present study, typical origin of the right and left hepatic artery from hepatic artery proper was 85% and in 15% cases it was found to arise from other sources. The right hepatic arteries those were not originated from hepatic artery proper, 8% was found to arise from common hepatic artery and 7% from superior mesenteric artery. But in case of left hepatic artery, remaining 15% was originated from common hepatic artery.

Gross anatomical study of spleenic length.

The aim of the present study was to establish the standard length of the normal spleen in Bangladeshi people. One hundred and twenty human cadavers of which eighty-seven male and thirty-three female were dissected to remove spleen with associated structures in the morgue of Forensic Medicine Department of Mymensingh Medical College. Collected specimens were tagged with specific identification number, divided into five groups according to age and height of the individual. Gross and fine dissections were carried out after fixing the specimen in 10% formol saline solution. Length of the spleen was measured by measuring tape and expressed in cm and findings of the present study were compared with the findings of national and international studies. This was a cross sectional descriptive study carried out in the Department of Anatomy of Mymensingh Medical College, Mymensingh. The mean length of spleen was maximum as 11.20 cm in male in group C (31-45 years), and as 11.80 cm in female in group B(16-30 years) and mean length of spleen was minimum as 10.06 cm in male and 9.53 cm in female in group A (upto 15 years). Difference between group A and B, A and C, A and D were statistically significant. There were no significant differences in between other groups. According to height of individual the mean length of spleen was maximum 11.42 cm in 165.01 to 180 cm height group and minimum 10.30 cm in 0-120 cm height group which indicate that length of the spleen increases with height of the individual. This was observed that length of the spleen depends on the age, sex and body height of the individual.
