2022Year8moon5On this day, the neurosurgery department of Ruijin People’s Hospital3DUsing printing technology, a very difficult and huge trans-sinus brain tumor resection operation was successfully carried out. The patient recovered well after the operation, all indicators were stable, and the patient’s physical reaction, communication and physical activity improved significantly.
Patients with parasagittal meningiomas after surgery5Speech delays, unresponsiveness, and reduced body movements have been occurring since 2001. throughCTThe examination diagnosed a tumor recurrence as a bilateral parasinus meningioma. The tumor is shaped like a tennis ball and is surrounded by a large number of blood vessels. The sagittal sinus, bilateral anterior cerebral arteries, and various draining veins are closely related to the tumor and may cause slight negligence in the operation. serious complications.
Before the operation, the neurosurgery team discussed in depth, formulated a detailed surgical plan, and used the workstation of Academician Zhong Shizhen of the hospital to3DPrinting technology, thanks to3DModel and print same-scale models of tumors and skulls, blood vessels, and more. in equal parts3DPrint the model to intuitively understand the surface positioning of the patient’s brain tumor, the relationship between the tumor and blood vessels, and the occlusion of the sagittal sinus. At the same time, the model is used to simulate surgical procedures repeatedly to formulate the best position, surgical path and plan, and make detailed plans for every detail.
Careful preparations from the start ensured the operation went smoothly. After the craniotomy, the hospital’s chief physician Zeng Ruiliang carefully operated under the microscope according to the preoperative plan and completely removed the tumor within an hour and a half. pass3DThe precise positioning of the printing technology and careful manipulation of each blood vessel around the tumor during the operation effectively shortened the operation time and significantly reduced the amount of bleeding. The brain tissue and blood vessels were well protected during the operation and postoperative aftermath3The patient can get up and move around within a few days.
