Complex cerebrovascular, 3D, sees it directly in front of your eyes and improves surgical safety
Nov 22, 2024
Domestic medical staff have developed a technology that can implement complex cerebrovascular vessels of patients in 3D and operate directly in front of them.
Professor Yoon Won-ki of neurosurgery at Korea University Guro Hospital developed a technology and program that can operate while checking the cerebrovascular structure in front of his eyes in real time during the surgery process by implementing a patient's cerebrovascular model in 3D using mixed reality 3D holography technology that combines VR and AR technology.
Using this technology, it is possible to check the anatomical structure of brain blood vessels in three dimensions during brain aneurysm surgery that requires a high degree of delicacy, and in particular, dangerous areas such as overlapping blood vessels can be checked in real time at 360 degrees, minimizing normal tissue damage and safer surgery. It can be seen by magnifying blood vessels as well as 360-degree rotation with simple hand movements.
There are two main ways to treat brain aneurysms. One is a clip ligation surgery by craniotomy and the other is a coil embolization surgery in which a coil is inserted into a blood vessel. Each has its strengths and weaknesses and characteristics, but all have three-dimensional cerebrovascular angiography to confirm the exact anatomical structure of blood vessels before surgery and proceed with surgery.
In particular, coil embolization is carried out using an imaging technology called cerebrovascular angiography, and despite the rapid development of cerebrovascular imaging techniques, there are still very clear limitations.
Even if a three-dimensional image is taken, the image is trapped in a two-dimensional monitor, so it cannot provide a spatial sense to the operator. Accordingly, in the past, the operator has to repeat the process of memorizing the entire patient's cerebrovascular image or reviewing the three-dimensional image again during surgery. However, this process increases the risk of surgery, and the treatment of complex or difficult aneurysms or brain aneurysms with intervascular angles is bound to be more at risk, and the newly developed technology has opened the way to overcome this.
Professor Yoon has applied the technology to more than 120 brain aneurysm coil embolization operations so far, and all of them have been successfully and safely completed. In particular, if the boundary between the mother artery (brain artery containing the aneurysm) and the aneurysm is unclear and a very large aneurysm is treated, there is a high possibility that microcavants and other instruments can penetrate the aneurysm or damage normal blood vessels, and this technology has enabled safe surgery.
To measure the effectiveness of applying this technique to surgery, several items (evaluation of the angle between aneurysm and maternal arteries, anatomical confirmation of overlapping blood vessels, re-confirmation of dangerous aneurysm walls, estimation of the location of microcatheter tips, etc.) were evaluated, and this technique was very useful in all aneurysm surgery. In particular, the most effective item was that surgery could be performed more easily and safely by sharply reducing the complexity of cerebrovascular vessels and confusion caused by vascular overlap that cannot be accurately identified in two-dimensional images.
Professor Won-ki Yoon explained that even when this technology was used for craniotomy clip ligation surgery, it was very easy to establish preoperative strategies and safer surgery was possible because the complex anatomical structure of cerebrovascular vessels could be grasped more precisely"The technique is also very easy to train medical staff with little experience in high-level surgery. In the future, it is expected that the field of virtual reality surgery education simulation, brain surgery navigation development using holography, and joint network simulator for patient explanation can be expanded and developed."
Meanwhile, the technology is attracting attention at domestic and international academic conferences. Professor Yoon said, "'The 17th Conference of the Korean Society of Neurological Surgeons (JKJC 2024)' held in Seoul in early September this year, '2024 Regular Conference of the Korean Society of Neurological Surgeons '2024,'2023 Summer Conference of the Korean Society of Neurological Surgeons 'Peyton Society Symposium', a group of alumni of the University of Minnesota Neurosurgery in the United States '2023 Regular Conference of the Korean Society of Neurological Surgeons ', '2022 Bi-Neurovascular Symposium. In addition, he won the Best Performance Award at the 2023 Winter Meeting of the Korean Society of Cerebrovascular Surgery for his research presentation on the technology.
