The relevance of the work is determined by the necessity to study markers of coagulation system of blood and hemocoagulation disorders in patients with pulmonary tuberculosis and comorbid diabetes mellitus in different stages of postoperative period. Aim. To determine the interrelation between markers of system of hemostasis and signs of development of intravascular blood coagulation in patients with pulmonary tuberculosis and comorbid diabetes mellitus (TB-DM) depending on the volume of surgical intervention on the respiratory organs. Materials and Methods. The extent of changes of markers of the system of hemostasis was determined in 89 patients with TB-DM before and after surgical treatment. Parameters of coagulation system of blood: concentration of fibrinogen, the level of soluble fibrin-monomer complexes, compensatory potentials by the level of fibrinolysis, activity of fibrinolytic system and of anticoagulation system (antithrombin III) were determined; parameters of prothrombin activity were studied. Besides, operation material of lungs was prepared for morphological examination. Results. A general tendency to increase in the parameters of hypercoagulation syndrome was identified in all the study groups starting from the 3rd-5th day and reaching maximum on the 7th-10th and 14th-17th days of the postoperative period, with compensatory activation of fibrin-stabilizing factor and of fibrinolytic system. Changes in the markers of hemostasis were most prominent in the group of patients after lobectomy. Microthrombotic lesions of the vessels of pulmonary microcirculation with partial or complete obturation of the lumen were morphologically visualized. Conclusion. On the basis of the data obtained a conclusion can be made about the existence of pronounced hypercoagulation syndrome with phenomena of intravascular coagulation of blood in this category of patients, which evidently requires timely prevention and treatment of thromboembolic complications. The results obtained may be used for development of measures aimed at prevention of hemocoagulation complications in patients with TB-DM after the conducted surgical treatment.

Bronchopleural complications after pneumonectomy in generalized destructive tuberculosis are associated with the presence of intrathoracic lymph nodes (ITLN) with caseous alterations. Aim. To improve the effectiveness of surgical treatment of patients with generalized destructive pulmonary tuberculosis by development and introduction of the method of mediastinal lymphadenectomy in tuberculous lesion of mediastinal lymph nodes. Materials and Methods. Results of surgical treatment of 515 patients with generalized destructive pulmonary tuberculosis were analyzed. In 274 of them the surgical treatment was supplemented with mediastinal lymphadenectomy (the main group). In the control group (241 patients) only resection was performed without removing lymph nodes. Results. Analysis of the postoperative course of the disease in both groups of patients (with mediastinal lymphadenectomy and without it) showed that bronchopleural complications occurred in 7 (2.6%) cases in the main group and in 30 (12.4%, p<0.05) cases in the control group. In the main group exacerbation of the specific process was noted in 1 patient (0.4%), and in comparison group in 9 patients (3.7%, p<0.05). Elimination of macroscopically altered ITLN in widespread destructive tuberculosis permitted to reduce the complications rate in the postoperative period by 64.8% (p<0.05). Indications to removal of IHLN included: a) enlargement of ITLN (>2 sm) and in duration; b) fusion with the surrounding tissues, softening of the node tissue in its caseous melting, c) existence of yellowish or whiter in comparison with the surrounding tissue inclusions in the node being manifestations of tuberculous granuloma. In histological, cytological and bacteriological examination, these macroscopic signs in 97% of cases indicated active tuberculosis of mediastinal lymph nodes. Conclusions. In 97% of cases, widespread destructive secondary pulmonary tuberculosis runs with an active specific process in mediastinal lymph nodes which makes it reasonable to perform a selective lymphadenectomy in such group of patients. Secondary damage of different groups of intrathoracic lymph nodes by the active process depended on localization of lung destructions and occurred along the routes of lymph drainage from them. Reliable signs of active tuberculous of ITLN include: more than 2.0 cm lymph node enlargement, in duration, periadenitis, fluctuation and in homogeneity. Removal of macroscopically altered intra-thoracic lymph nodes in widespread destructive pulmonary tuberculosis permits to reduce the rate of complications in the postoperative period by 64.8%.
