Evaluation of multiple ventricular septal defects using three-dimensional reconstruction models.
Eur J Cardiothorac Surg
March 2025
Department of Pediatrics, University of Toyama, Graduate School of Medicine, Toyama, Japan.
Objectives: Although there has been rapid development in the field of three-dimensional morphological analyses of congenital heart disease, with the three-dimensional volume-rendered images providing visualization of the external vascular anatomy, the precise reproduction of "Swiss-cheese" ventricular septum is not well established. We created three-dimensional printed models and computer graphics based on multi-slice computed tomography of patients with complex multiple ventricular septal defects for surgical decision planning of this difficult cardiac defect.
Methods: Seven patients with complex multiple ventricular septal defects were evaluated preoperatively using three-dimensional printed models and computer graphics to plan therapeutic interventions.
Advancements in Three-Dimensional Super-Resolution Ultrasound Imaging: A Narrative Review.
J Ultrasound Med
March 2025
Department of Biomedical Engineering, Department of Small Animal Clinical Sciences, Texas A&M University, College Station, Texas, USA.
The lack of sensibility of traditional ultrasound (US) imaging to the slow blood flow in small vessels resulted in the development of microbubble (MB) contrast agents. These MBs are given intravenously, and US imaging can detect them quite effectively. This noninvasive imaging method, known as contrast-enhanced US (CEUS), now makes it possible to accurately assess tissue perfusion and blood flow.

Front Bioeng Biotechnol
February 2025
Hospital of Stomatology, Guanghua School of Stomatology, Sun Yat-Sen University and Guangdong Provincial Clinical Research Center of Oral Diseases, Guangzhou, China.
Purpose: This study aims to investigate the stress distribution in bone tissue, implant, abutment, screw, and bridge restoration when the mesial implant is placed axially and the distal implant is inserted at varying angles in the posterior maxillary region with free-end partial dentition defects, using three-dimensional finite element analysis.
Materials And Methods: Cone-beam computed-tomography were utilized to create 3D reconstruction models of the maxilla. Stereolithography data of dental implants and accessories were used to design a three-unit full zirconia bridge for the maxillary model.
Classification in 157 patients with Lisfranc injuries using three-dimensional fracture lines and heat map.
J Orthop Surg Res
March 2025
Department of Orthopedics, The Affiliated Traditional Chinese Medicine Hospital, Southwest Medical University, Luzhou, China.
Background: Recently Lisfranc fractures have increased due to increased high-energy injuries from various causes. However, due to incomplete traditional classification, the pattern and distribution of fractures cannot be analyzed in three dimensions. This study examines a novel fracture pattern based on the fracture line and heat map for Lisfranc injuries.

Hernia
March 2025
Department of Visceral, Transplant, Thoracic and Vascular Surgery, University Hospital of Leipzig, Liebigstraße 20, 04103, Leipzig, Germany.
Purpose: Burst abdomen (BA) is a relevant complication after abdominal surgery that causes additional surgical procedures, prolonged hospital stays and long-term morbidity. Several underlying risk factors exist and have been characterized previously. Those risk factors consist of surgical and medical factors.
