From stages of history to regularities of changes in body cavities after radical operations on lungs

Close metadata

BACKGROUND

There is the description of the history of body cavities changes after radical lung surgery, determined by the intravital research, in this article. The significance of experimental, radiological methods, intravital computer (CT) and magnetic topographies are showed. Named methods make it possible to perform complex investigations, morphometric value, analysis and generalization of received data. Then it allows to formulate of postoperative changes patterns.

OBJECTIVE

Aim of the article is the presentation of patterns of regional-anatomy changes in body cavities after radical operations on lungs.

MATERIAL AND METHODS

Materials were data from computer tomograms of 154 patients after pneumonectomy and lung lobectomy. The following methods of investigation were applied: multispiral computer tomography, 3D-modelling, morphometry of anatomical construction and topography of anatomical structures on CT-grams, variation statistic processing of quantity data.

RESULTS

There are 9 patterns. The first determines complex from 5 regularities changes. After pneumonectomy 5 regular regional-anatomy changes take place in thoracic and abdominal cavities: the dislocation of mediastinum and its organs, changes of thoracic wall, increase of remaining lung with forming of mediastinal hernias, cupula of diaphragm lifting on side of operation and subsequent regional-anatomy changing of abdominal. The following regularities describe every group of post operational changes, concreting their keeping.

CONCLUSION

The study of regional — anatomy changes in pulmonary surgery has historically step-by-step nature. One’s is determined by the possibilities of lifetime methods of pre- and postoperative examination of cavities and organs. Multispiral computed tomography gives wide opportunities for comprehensive in-life study, analysis and generalization of postoperative changes in thoracic surgery. The above 9 patterns describe in general a complex of 5 regional — anatomy changes that naturally occur in the thoracic cavity and abdominal cavity, having both fundamental and clinical mean.
