Abstract:
The study was undertaken to evaluate the normal microangiograhic findings of the brain and to assess the effect of varying perfusion technicque of the microangiography in the rat. All the microvascular structures including fine medullary branches of the perforating arteries and anastomotic capillary netweks are well visualizedin both 15 minutes-pefusion group and 30 minutesperfusion group. But many of the micorvascular structures are notuniformly opacified in the both groups. There is no difference in microangiographic findings between these groups.There is poor perfusion of the micorvascular structures in the 3rd group, the group with perfusion for 30 minuteswithout ligation of aorta below the needle insertion site. The new, simple perfusion technique should be developedto obtain the best quality of the microangiographic findings in the brain of the experimental animals.
