RESUMEN
With the continuous improvement of surgical techniques and perioperative management, the success rate of lung transplantation has gradually increased, but airway complications after lung transplantation are still common. Airway complications after lung transplantation may reduce the quality of life, increase medical costs, and even threaten the lives of the recipients. In 2018, the International Society for Heart and Lung Transplantation (ISHLT) consensus proposed that airway complications included ischemic necrosis, anastomotic dehiscence, airway stenosis and tracheobronchomalacia. Bronchoscopy remains the gold standard for the diagnosis of airway complications. However, during the follow-up of lung transplant recipients, use of end-inspiratory CT scan combined with end-expiratory or dynamic expiratory CT scan may contribute to identifying a variety of airway complications, evaluating the location and degree of airway complications and providing beneficial supplement for the selection of clinical treatment.
RESUMEN
Objective:To explore the application value of preoperative multimodal image fusion 3D reconstruction technology in brain tumor surgery.Methods:The preoperative cranial CT and MR imaging data of 46 patients with brain tumors admitted to our hospital from October 2019 to September 2020 were collected. The image registration and fusion of above imaging data were performed by AW workstation software (GE company), and 3D reconstruction was performed to construct 3D digital anatomic image of brain tumor and its surrounding anatomic structure. Based on this, the surgical approach and surgical plan were designed, and its application value was evaluated by consistency grading.Results:The reconstructed 3D digital anatomical image could clearly show the size, location, shape of the tumors and the anatomical relationships between the tumors and surrounding structures, which was consistent with the original image before and during the surgery. Among the 46 patients, 43 were completely resected and 3 were partially resected. There were no approach-related complications after surgery. The application value of preoperative 3D image fusion was evaluated as 36 with outstanding value, 8 with value, and 2 without value.Conclusion:Preoperative multimodal image fusion 3D reconstruction technology can provide a large amount of visual information during brain tumor surgery, guide the choice of surgical approach and precise resection of tumors.
