Abstract: (1773 Views)
Background: Many arteries are responsible for nutrition of brain tissue that one of them is the middle cerebral artery with its branches (perforating arteries). The collapse or injury in each of these branches lead to brain stroke or pathologic injury in brain so perforating arteries has anatomic importance and also it is necessary to recognize these arteries therefore we decided to measure length, outer diameter and number of these vessels in middle cerebral artery.
Materials and Methods: In this descriptive study 26 Brains (21 male and 5 female) of people who were dead by non brain problems causes were surveyed using usual dissection method. The brains were taken out in Kerman forensic medical center and dissection of the brains were performed in Depatment of anatatomy, Kerman faculty of medicine.
The length, diameter and number of perforations were measured in middle cerebral artery (MCA). Data were analysed by t-test.
Results: Results showed that the main number of perforating artery branches was 6.03 in right and 6.57 in left the differences between two parts were not significant. The mean length was 13.61±0.05 in right and 13.72±0.51 in left that were not significantly different. The mean outer diameter was 0.49±0.01 in right and 0.58±0.03 in left the difference was significant (p<0.05).
Conclusion: This study sshowed that the outer diameter of perforating arteries in MCA were significantly differente in right and left brain, but the other variables were not significantly different in right and left brain.
