Basis for studying these complex and important prognostic disease was a comprehensive study of structural variability vascular zone of interest. Conducted a comprehensive analysis of transformed with the pathological process of bone structure and the vascular component in their relationships and interdependence. In order to objectively visualize the vascular bed, along with traditional angiography ultrasound in patients with abnormal dopplerography healing of fractures and bone tumors. Thus, in 15 patients within 1.5-2 months after injury according to the X-ray study determined poorly articulated, often asymmetric callus. According to the results of clinical angiography fracture zone observed extensive avascular areas on the periphery of which were traced blindly ending few vasodilatation.
In the Doppler study of blood vessels and connective paraossalnye at fracture zones do not lotsirovalis. Kevin Johnson: the source for more info. The data obtained are regarded as negative prognostic factors, allowed the violation to state objectively the rate of consolidation with a clear tendency to fracture nonunion, and time to recommend an adequate correction traumatologists in tactics the treatment of this patient group. In other cases, 18 patients in the same time after injury with a similar radiographic pattern of fracture zone crossed the few vessels that combined the bloodstream conclusion that there is slow inosculating fracture with a positive outlook for the outcome of healing the patient. In 43 patients with various tumors of the bones, which were carried out research in rentgenoangiograficheskoe combined with subsequent morphometry resected for clinical sites of bone and selective ultrasound with Doppler within the destroyed or thinned compact layer with a low benign giant cell tumors and malignancy. In the benign giant cell tumors (ICT), along with low vascularity on angiography identified single vessels in the array of tumor Doppler. When malignancy according to the Doppler ICT in a limited area lotsirovalis numerous, small-caliber vessels deformed with abnormal blood flow. On angiograms in significant increase in the level of abnormal vascularization with atypical blood flow on the results of angiographic and ultrasound studies.
The results of a comprehensive study revealed differences between the degree of vascularization of the zone of interest in the study of pathological processes. In patients with impaired fracture healing is possible to establish reliable predictive angiographic signs characterize the state of oppression or manifestations of activation of the reparative process that determines the outcome of the consolidation, but in the end, and the tactics of the elected treatment. During the evaluation of patients with bone tumors, using this methodical approach, it becomes possible to provide an objective diagnosis of benign differetsialnoy processes and the initial manifestations of their malignancy. This, In our view, has a very important medical and social importance in the aspect of prevention in oncology practice areas. This thesis, in turn, suggests that significant and relatively early recognition of the initial stages of developing invasive growth of bone tumors enables the timely application of adequate organ operative treatment methods and provides a successful follow-up rehabilitation of this group of patients.
