Peculiarities of surgical tactics of patients with thymus tumors

Abstract

The aim of the study: to study retrospective analysis results of the surgical treatment of thymus tumours for predicting long-time results. Methods. Study included 35 patients who were treated at the Department of Thoraco-abdominal Surgery from September 2019 to May 2021. The control group included 20 patients with SVCS were treated with conventional techniques, while the experimental group included 15 patients who underwent a novel bypass surgery developed by us. Results. The venous bypass was mandatorily complemented with cytoreduction. Complications in the post-operative period were reported from the experimental group and included auriculo-subclavian bypass thrombosis, post-operative complications were reported in the control group including haemorrhage from the sternotomy wound in 1 (3.3 %) case, superior vena cava thrombosis in 2 (6.6 %) cases, pneumonia in 2 (6.6 %). The relative risk of complications and lethal outcome was calculated for patients from both groups. It was found that the risk of complications was twice as high in the control group as in the experimental group (standard error of relative risk equals 0.64). Conclusion. The first mandatory step of the radical surgery in patients with thymomas with SVC invasion should be the auriculo-jugular and auriculo-subclavian bypasses, which can reduce the relative risk of post-operative complications by a factor of the risk of lethal by a factor of 3.5
