Tracheal neoplasms are rare tumors and characterized by delayed diagnosis after clinical manifestation (tracheal stenosis and associated complications). These tumors often occur an advanced age patients that complicates examination and surgical treatment. High risk is determined by type of surgery, possible postoperative complications and senile age.Long-term outcome of surgical treatment of a patient with severe aortic insufficiency and ascending aortic aneurysm is reported. The patient underwent Bentall-DeBono procedure with xenopericardial valved conduit. This technique is associated with no complications specific for Dacron conduits and ensures clinical compensation of heart failure, improves prognosis and quality of life.Objective To evaluate the results of treatment of recurrent nodular goiter using sclerotherapy with polidocanol. Material and methods A comparative analysis of sclerotherapy (30 patients) and conventional surgical treatment (17 patients) of recurrent goiter was performed. Results Sclerotherapy ensures reduction of nodes (linear dimensions of nodes decreased by 14.2±1.1 mm after 3 courses), correction of endocrine imbalance in patients with functional autonomy and relief of initial signs of cervical organ compression in all patients with recurrent goiter. Sclerotherapy is associated with less pain syndrome and no need for inpatient treatment. However, the most significant advantage is reduced risk of complications. Hypoparathyroidism and laryngeal paresis developed in 53 and 24% of patients after conventional surgery while these events were not observed after sclerotherapy. Conclusion Sclerotherapy with polidocanol is a perspective alternative to conventional surgery for recurrent nodular goiter.Increase of the frequency of soft tissues pyoinflammatory diseases and
