In cardiac surgery, CT, MRI, B-ultrasound and other examinations can only provide two-dimensional images. Doctors cannot see the whole picture of the heart directly, and cannot directly observe its internal fine structure. Therefore, it is difficult to grasp accurate and comprehensive patient information. Saina's WJP direct-injection color multi-material 3D printing technology can convert the patient's two-dimensional image data into a full-color 3D printing model of one-to-one size before the operation, vividly presenting the heart structure, blood vessels and other internal structures It is in front of doctors and can provide more rich information that is difficult to display in traditional imaging examinations, thereby greatly simplifying and standardizing the above-mentioned complex procedures, making the operation more accurate and safe.
|Apply for a hospital||Guangdong Provincial People's Hospital||Patient condition||Lin Moumou|
|Condition description||Pulmonary atresia type IV is accompanied by ventricular septal defect. The patient can survive by the large collateral vessels from the aorta to supply blood to the lungs, but the patient's heart function is very poor.|
|Surgery difficulties||Based on two-dimensional CT images, doctors have a relatively abstract grasp of the position, size, and shape of the patient's collateral vessels, and it is difficult to accurately determine the specific conditions of the collateral vessels. During the operation, the patient cannot perform its own blood circulation, so it is necessary to perform extracorporeal circulation on the patient. The longer the extracorporeal circulation, the higher the incidence of postoperative complications and the overall risk. There are many complications in the operation, including but not limited to Respiratory damage, brain damage, etc.|
|Treatment programs||Adopting radical surgery, the approach of thoracotomy from the middle, using the spatial position of the bronchus as a marker point, under the guidance of these delicate models, Dean Zhuang Jian and Director Cen Jianzheng quickly and accurately found all the collaterals and successfully reconstructed the entire pulmonary artery Tree, completed the entire operation according to the established plan|
|Advantage||1. Shorten the operation time and reduce the risk of complications caused by cardiopulmonary bypass. |
2. The cost of patient expenses is reduced because the increased cost of printing a 3D model is less than the time cost and the concurrent cost of treatment drugs caused by no model.
3. Improve the utilization rate of hospital operating rooms, and be able to do more operations per unit time
