Challenges of the Endovascular Approach for Difficult Cerebral Aneurysms

Abstract

The endovascular approach, as a less invasive method, has been used to deliver direct surgery for the treatment of cerebral aneurysms. With the rapid and evolutional improvement in imaging technology, devices, treatment skills, and perioperative managements, the success rates of endovascular treatments have been increasing annually. Particularly, endovascular treatments are highly expected for surgically difficult aneurysms, such as large aneurysms, or for those similar to tiny blood blisters. The flow diverter, one of the breakthrough devices, has improved the clinical results of these aneurysms. As another challenge, robotics may resolve the problems of radiation exposure for the operator by allowing remote telesurgery. Such a recent challenge with novel devices and technologies is introduced here, along with our own experiences.
