Chylothorax is a rare but severe complication of cardiac surgery. The authors present the case of a 76-year-old woman suffering from ischemic heart disease, after coronary artery bypass grafting that included a left internal mammary artery pedicle graft. On the ninth postoperative day the left-sided fluidothorax developed. The results of biochemical analysis were consistent with the chyle. Combined treatment with pleural drainage and total parenteral nutrition was effective.

Background. One option for the palliative treatment of recurrent malignant pleural effusion is powdered talc using thoracoscopy. This paper presents the results of selected systemic and local manifestations of the talc-induced inflammatory reaction using a videothoracoscope. Method. A total of 114 patients with repeated malignant pleural effusion were treated at the Cardiac Surgery Clinic in Hradec Kralove from January 2010 to December 2012. Those with a life expectancy more than ≥ 3 months were eligible for talcage surgery. The group was retrospectively divided according to treatment results into Group A (N 1 = 98 -successful) and Group B (N 2 = 16 -relapsing). The pleural effusion was quantified using ultrasound over 1 year at 3-month intervals. Systemic changes due to the inflammatory reaction (body temperature, serum leukocyte and CRP levels) were evaluated. Local indicators of inflammation included changes in the leukocyte cell population in the effusion and changes in the pleural CRP levels. The dynamics of local expression of membrane receptors TLR-2 and CD-64 on granulocyte and monocyte cell populations in the pleural effusion were also evaluated. Results. The reaction after talcage, included a significant increase in axillary temperature and leukocyte count, 12 h after the procedure. The dynamics were different in the two groups. The dynamics of local inflammatory changes were an early increase in the pleural CRP levels in both groups. The time interval of local inflammatory development and duration was related to the treatment efficacy and showed a significant rise 2 h after talcage in Group A. In Group B the local inflammatory reaction was slower and the rise was only observed 24 h after talc application. A decrease in lymphocyte count and an increase in granulocyte count 2 h after talcage were found. After an initial drop in monocyte level, a rise occurred within 24 h after talcage. Changes in the expression of TLR-2 and CD-64 receptors in relation to their cell carriers were observed depending on time after talcage. Conclusion. The differences in the serum and pleural effusion CRP levels suggest that the surgical stress manifests itself locally in the pleural space with a lower intensity and time delay. The TLR-2 and CD-64 receptors exhibit different behaviour depending on the type of cell membrane where they are found. The inverse relation between the granulocyte increase and TLR-2 receptor decrease in the membrane immediately after talcage is a new finding. The dynamics of TLR-2 expression on the monocytes demonstrates a direct proportion between the increasing expression of the TLR-2 receptor and increasing percent fraction of the cell carrier.

The authors present a rare and unusual case of complication, migration of osteosynthetic material for stabilization, titanium rod, which was used for stabilization of comminutive fracture of the first lumbar vertebra. This rod migrated from the retroperitoneal space to the pleural cavity. The removal of this rod was carried out by videothoracoscopy.

The aim of this study was to examine the role of TLR2 molecule in pleural space during thoracoscopic talc pleurodesis period in patients with malignant pleural effusion. We analyzed TLR2 molecule in soluble form as well as on membrane of granulocytes in pleural fluid. Pleural fluid examination was done at three intervals during pleurodesis procedure: 1st—before the thoracoscopic procedure, 2nd—2 hours after the terminating thoracoscopic procedure with talc insufflation, 3rd—24 hours after the thoracoscopic procedure. We reported significant increase of soluble TLR2 molecule in pleural fluid effusion during talc pleurodesis from preoperative value. This increase was approximately 8-fold in the interval of 24 hours. The changes on granulocyte population were quite different. The mean fluorescent intensity of membrane TLR2 molecule examined by flow cytometry on granulocyte population significantly decreased after talc exposure with comparison to prethoracoscopic density. To estimate the prognostic value of TLR2 expression in pleural fluid patients were retrospectively classified into either prognostically favourable or unfavourable groups. Our results proved that patients with favourable prognosis had more than 3-fold higher soluble TLR2 level in pleural fluid early, 2 hours after talc pleurodesis intervention.

Background. Malignant pleural effusions accumulate in the space between the visceral (inner) layer covering the lungs and the parietal (outer) layer covering the chest wall. Larger effusions compress the pulmonary parenchyma resulting in increasing dyspnoea. Treatment is always local and palliative. Among others, chemical pleurodesis using talc can be performed in selected patients. Talc is hydrated magnesium silicate (chemically H 2 Mg 3 (SiO 3 ) 4 ) and has been used for pleurodesis since 1935. Videothoracoscopic talc powder insufflation (talc poudrage) is the most effective.However, markers of inflammatory reactions to extraneous substances like talc are not fully understood. The aim of this study was to assess the course of local inflammatory changes in the pleural cavity after talc insufflation. Methods. The Department of Cardiac Surgery of the Faculty of Medicine and University Hospital in Hradec Kralove, treated 47 patients aged 65 on average; 29 males and 18 females with proven recurrent malignant pleural effusion of various aetiologies from January 2009 to December 2010. They were retrospectively divided into group A (40 patients) without recurring effusion, and group B (7 patients) with recurring effusion and the need for thoracentesis or chest drainage during the 9-month monitoring. Results. Major findings were made in soluble forms of cell receptors. Group B showed statistically higher levels of the anti-inflammatory form of sCD-163 receptor in pleural fluid before the talc poudrage. This showed limited ability to create an adequate inflammatory response to external stimuli. This group also showed lower levels of the inflammatory form of sTLR-2 receptor immediately after the talc insufflation. This revealed low local reactivity to external stimuli. The effect of the treatment was not influenced by morphologic tumour type. No statistically significant differences in postoperative complications were found. This confirmed the safety of both videothoracoscopy and treatment. Conclusions. There was no correlation between the type of malignant affection and the outcome of the chemical pleurodesis. Patients with relapsing effusion have higher values of concentration of anti-inflammatory sCD-163 in pleural fluid even before the application of talc, and lower levels of concentration of inflammatory sTLR-2 immediately after application of talc.

summary: The authors demonstrate the possibility of improving surgical results by the reduction of perioperative bleeding in thoracic surgery associated with extended resection procedures. We focused on patients in whom the expected perioperative blood loss was greater than 500 ml. The first group consisted of patients with lung cancer stage III A after neoadjuvant chemotherapy had been indicated to extend the resection procedure. The second group consisted of patients with chest wall and mediastinum tumors of various etiologies. The third group consisted of patients with post-inflammatory thoracic complications in whom combined decortication and pleurectomy was necessary. By the using the local hemostyptic Traumastem TAF on the basis of oxidized cellulose, it is possible to minimize the perioperative blood loss, thus sparing the blood derivative requirement and enabling surgeons to provide the desired treatment even to high-risk patients.

The purpose of the study was a retrospective evaluation of the outcome of surgical therapy of lung cancer in patients where there was concomitant cardiac disease and who underwent a cardiac operation either because of ischemic heart disease or because of valvular disease. These patients were operated on at various time intervals (two to ten months) after their cardiac operation. Some patients had their lung cancer surgery after the cardiac operation because of the high risk of possible cardiac postoperative complications; in one patient the lung operation preceded the cardiac one.
