[Study of local capillary circulation using labeled albumin microspheres during osteotomy of the maxilla (experimental study)].
The authors presented the results of experiments on 14 random bred dogs in whom fragmentary osteotomy of the maxilla at the level of 7 perpendicular 7 teeth was performed with subsequent investigation of the volumetric blood flow rate in soft and osseous tissues of the osteotomized fragment using labeled albumin microspheres. The animals were divided into 4 groups (the study group and control groups). The volumetric blood flow rate was investigated over time with the monitoring of the CV system 1 (the 2nd group), 6 (the 3rd group) and 24 h (the 4th group) after operation. The total reduction of the blood flow in the tissues of the osteotomized fragment as compared to that of the control group was 54.5% (in the 1st group), 39.3% (in the 2nd group) and 41% (in the 3rd group). The results of the study showed correlation between the blood flow rate reduction in the soft tissue structures and osseous tissue.
