RESUMEN

We present a case report of a 47-year-old male with an extensive tissue deficiency of the right lower leg. The patient was hospitalized for approximately one month in the intensive care unit following a motorcycle accident that resulted in polytrauma. He suffered a fracture of frontal and parietal bones, traumatic brain injury, intracerebral hematoma with a subarachnoid hemorrhage and thoracic trauma. At first, lower leg wound was treated with a negative pressure wound therapy vacuum-assisted closure (VAC) dressing. Afterwards, he was qualified for a surgical wound closure with synchronous use of two reverse flow flaps: a reverse sural flap (RSF) and a reverse hemisoleus muscle flap (RHMF). Both flaps were dissected, and the RHMF was used to cover the exposed bone and the fracture site while the RSF closed the distal part of the wound. Split-thickness skin graft was meshed in scale of 1:1.5 and used to cover the RHMF and the remaining lower leg wounds. In the following days, uneventful wound healing was observed and the patient was discharged on day 34. The patient was invited for a follow-up examination two years after the procedure. His quality of life was assessed using SF-36 and Lower Extremity Functional Scale. It was determined to be satisfactory when compared to patients with identical injuries. Ultrasound examination of the gradient and blood flow velocity showed preserved graft perfusion and no structural abnormalities were detected. Adequate wound preparation and the choice of surgical technique allowed rapid healing and, above all, salvage of the limb that was at high risk of amputation.

RESUMEN

Background: In the era of percutaneous aortic valve implantation, biological valves are the preferred prostheses implanted in patients undergoing surgical aortic valve replacement (sAVR). The aim was to present a real-life analysis of mid-term sAVR outcomes for the four aortic bioprostheses: the Hancock II, the Carpentier-Edwards Perimount Magna, the Carpentier-Edwards Perimount Magna Ease and the Trifecta valve. Methods: This is a retrospective study based on data from the Polish National Cardiac Surgery Database. The study population comprised of 1,589 consecutive patients, of whom 432 were in the Hancock II group, 356 in the Carpentier-Edwards Perimount Magna group, 427 in the Carpentier-Edwards Magna Ease group, and 374 in the Trifecta group. A comparison of the four groups was performed using analysis of variance (ANOVA) or Kruskal-Wallis test with appropriate post hoc tests (Tukey HSD or Steel-Dwass, respectively). Results: Patients in the Hancock II group were older, had higher New York Heart Association (NYHA) and Canadian Cardiovascular Society (CCS) classes, had lower prevalence of hypertension and hyperlipidemia but higher prevalence of diabetes. The lowest mean valve size was observed in Trifecta group and the highest was in the Magna group (P<0.001). Survival analysis showed no significant differences in in-hospital mortality: 3.9% in Hancock II, 3.1% in Perimount, 3.3% in Magna and 2.1% in Trifecta group. Five-year mortality was significantly higher in Hancock II group (25.7%) compared to the other bioprostheses: 12.1% in Perimount, 9.1% in Magna and 10.70% in Trifecta group respectively. Conclusions: The 5-year mortality rate was significantly higher in the Hancock II group compared to the other bioprostheses. In contrast, Trifecta, Perimount Magna, and Magna Ease had similar 5-year mortality rates.

RESUMEN

BACKGROUND: Our understanding of facial anatomy has significantly evolved, yet the detailed contraction patterns of facial muscles and their presentation during clinical imaging remain largely unexplored. Understanding the contraction patterns and visual presentation of these muscles, particularly the zygomaticus major could enhance pre-surgical facial assessments and the development of new treatment strategies. METHODS: A total of 34 healthy young individuals (17 female, 17 male) with a mean age of 23.6 (2.4) years [range: 20-30] were investigated regarding the length, thickness, width, and angle of the zygomaticus major muscle in five different facial expressions (i.e., repose, anger, joy, surprise, and sadness) utilizing MR imaging. RESULTS: Joyful expressions caused a reduction in muscle length to 85.6% of its original length and an increase in width (103.4%), thickness (108.4%), and facial angle (2.72°) when compared to that in repose, suggesting isotonic contraction. Conversely, expressions of anger, surprise, and sadness generally led to muscle stretching, seen through changes in length (98.9%, 104.3%, and 102.7%, respectively), width (98.8%, 96.5%, and 99.4%, respectively), and thickness (91.2%, 91.0%, and 102.7%, respectively), with variable alterations in facial angle (0.55°, 1.85°, and 1.00°, respectively) depending on the specific expression. CONCLUSION: This MRI-based study indicates that the zygomaticus major muscle experiences isotonic contraction, characterized by decreased length and increased width and thickness. The findings underline the importance of muscle thickness as a reliable parameter in assessing facial muscle function and offer valuable guidance for practitioners in accurately evaluating muscle performance during different facial expressions.
