Introduction Mucoepidermoid carcinoma, compared to other tumors of salivary glands, occurs in 5-10% of cases. Histopathologically, it is divided into a well differentiated tumor that is of low-grade of malignancy, and a medium and poorly differentiated tumor of high grade of malignancy. Central mucoepidermoid carcinoma (CMEC) of the mandible was firstly described by Lepp in 1936, on a 66-year-old female patient. CMEC is characterized by atypical clinical image and radiological manifestation. Case Outline A 55-year-old female patient was examined at the Clinic of Dentistry in Niš, Serbia, with anamnestic data regarding the presence of painless swelling in the right side of the mandible. Considering the histopathological results and presence of enlarged lymph nodes, right hemimandibulectomy and tumour excision from pterygomandibular space followed by supraomohyoid neck dissection was done. In due course, postoperative radiotherapy was applied (60 Gy). Conclusion CMEC represents a rare tumor, characterized by local tissue destruction and ability to metastasize. Initial biopsy represented the key in preoperative planing. Radical excision with neck lymph node dissection followed by postoperative radiotherapy in our case represent a successful method of treating CMEC of the mandible. © 2016, Serbia Medical Society.

Background and Objectives: The saphenous vein graft (SVG) remains the most frequently used conduit worldwide, despite its common disadvantage of early graft failure. To solve the problem and reduce the SVG damage, Souza implemented a new technique where a vein is harvested with surrounding fascia and fat tissue (the so-called no-touch technique). Materials and Methods. A prospective study conducted from February 2019 to June 2024 included 23 patients who underwent myocardial revascularization using a no-touch vein, with follow-up control examinations using computed tomographic angiography to detect graft stenosis or occlusion. Results. Of the entire patient group, 17 (73.9%) were male, with a mean age of 67.39 ± 7.71 years. The mean follow-up period was 25 months. There were no major adverse cardiovascular or cerebrovascular events (MACCEs) during hospitalization, although one patient died in the hospital. Another patient died due to malignancy, but no MACCEs occurred during the follow-up period. According to multi-slice CT coronary angiography, the results were impeccable, with an astonishing 100% patency observed in all 20 IMA grafts and 58 no-touch SVGs examined. Conclusions. The excellent patency rate during the early follow-up period confirmed that the no-touch technique is a good option for surgical revascularization. © 2024 by the authors.

Introduction/Objective Even with the current treatment, mortality from aortic dissection remains high. The study aimed to evaluate the early postoperative outcome of patients with aortic dissection and identify which factors could influence it. Methods The study included all consecutive patients who underwent surgery for acute aortic dissection type A from 2012 to 2017. We registered all parameters that could potentially impact the outcome (general data, medical history, clinical and cardiological diagnostic test findings, preoperative complications, type of cannulation and the operation performed, additional surgical procedures, operation duration, etc.). The patients were surgically treated according to the current protocols. The main outcome measures were complications and mortality during a one-month postoperative period. All data collected pre-, intra-, and postoperatively were compared and statistically analyzed. Results The study included 246 patients, 57.54 ± 12.88 years old on average, and mostly of male sex (74%). Early postoperative mortality occurred in 17% of the patients. Preoperative chronic kidney insufficiency (p = 0.005) and cerebrovascular insult (p = 0.047) and tamponade (p = 0.036) were the major risk factors for postoperative complications and mortality. Long hypothermic cardiac arrest (p = 0.001), cross-clamp (p = 0.017) and cardiopulmonary bypass time (p = 0.036) increased postoperative compli-cations. Postoperative complications started occurring after ≥ 33.5 minutes hypothermic cardiac arrest and ≥ 67.5 minutes cross-clamp time. Postoperative complications occurrence increased (p = 0.034), while performing anterograde cerebral perfusion decreased the frequency of lethal outcome (p = 0.001). Conclusion The majority of patients surgically treated for acute aortic dissection had good postoperative outcome. However, numerous pre-, intra-, and postoperative factors can impact patient survival. © 2021, Serbia Medical Society. All rights reserved.

Less invasive coronary artery bypass grafting surgery is underused despite more than 25 years of interest from surgeons and growing patient demands for less pain and rapid full recovery. New approaches may offer surgeons additional options to provide enhanced clinical results through reliable subxiphoid bilateral internal thoracic artery harvesting and the creation of durable anastomoses through very small thoracotomy incisions. This first-in-human case report describes 2 patients who received surgical coronary revascularization using the µCAB™ technology and techniques. The encouraging early results indicate that the µCAB™ approach may offer a new ergonomic, affordable method for coronary revascularization with less surgical trauma. © The Author(s) 2023.

The incidence of sternal wound complications, such as dehiscences, infections, and sternocutaneous fistulas, can reach 10%. Sternocutaneous fistulas are extremely rare, and the only definite therapy is surgical repair. Our experience taught us that combining a traditional approach with an extracellular matrix patch might be a step forward in therapy. We described three examples of surgically reconstructing sternocutaneous fistulas with an extracellular matrix patch (ProxiCor®). © 2025, Sociedade Brasileira de Cirurgia Cardiovascular.
