A new approach for thymectomy in case of mediastinal shifting is proposed. Parasternal access provides optimal conditions for performing an adequate thymectomy, does not require single lung ventilation and could be used after previously performed pneumonectomy.

Abstract In this paper, we provide a new approach for the anionic modification and functional application of nanocellulose. The nanocrystalline cellulose (NCC) is prepared from microcrystalline cellulose (MCC) and modified by fatty acids (lauric acid, palmitic acid and stearic acid). Ammonium ceric sulfate or hydrogen peroxide/ferrous sulfate being used as an initiator, three kinds of modified nanocrystalline cellulose (MNCC) can be synthesized at low temperature. The terminology for these MNCC is L-MNCC (NCC modified by lauric acid), P-MNCC (NCC modified by palmitic acid) and S-MNCC (NCC modified by stearic acid). Compared with those existing synthesized methods, the reaction condition is mild, and the modified products show strong stability. It can be seen from morphological structure analysis and reaction conditions analysis of MNCC that the original structure of cellulose is changed slightly. And the optimal conditions for preparing MNCC are obtained. The best yields of L-MNCC, P-MNCC and S-MNCC are 54.2 %, 20.9 % and 14.5 %, respectively.

Abstract: Introduction: Most modern thoracic operations are performed with single-lung ventilation balancing between convenient surgical approach and adequate gas exchange. The technical limitations include difficult airways or insufficient parenchyma for the intraoperative single-lung ventilation. Earlier, cardiopulmonary bypass was the only solution, however, today the extracorporeal membrane oxygenation is in the forefront. Aim: We retrospectively analysed our elective operations by use of venovenous ECMO to assess the indication, safety, perioperative morbidity and mortality. Patients and method: 12 patients were operated using venovenous (VV-) ECMO between 28 April 2014 and 30 April 2018 in the National Institute of Oncology. The main clinicopathological characteristics, data regarding the operation, the use of ECMO and survival were collected. Results: The mean age was 45 years, 2 patients had benign and 10 had malignant diseases. Extreme tracheal stricture was the indication for ECMO in 3 cases, while 4 patients had previous lung resection and lacked enough parenchyma for single-lung ventilation. 5 patients had both airway and parenchymal insufficiency. The average time of apnoea was 142 minutes without interruption in any of the cases. We did not experience any ECMO-related complication. We had no intraoperative death and 30-day mortality was 8.33%. Conclusion: In case of technical inoperability, when there is no airway or insufficient parenchyma for gas exchange, but pulmonary vascular bed is enough and there is no need for great-vessel resection, VV-ECMO can safely replace the complete gas exchange without further risk of bleeding. The use of VV-ECMO did not increase the perioperative morbidity and mortality. Previously inoperable patients can be operated with VV-ECMO. Orv Hetil. 2019; 160(42): 1655–1662.
