Summary

Advancements in the field of endovascular neurosurgery have resulted in unprecedented shifts in treatment paradigms and practice patterns. Novel implantable devices, improved catheter constructions, and new insights into disease pathomechanisms have encouraged providers to expand the indications for endovascular interventions and offer new treatment options for lesions that were previously thought to be inoperable or surgically high-risk. These include flow modifying devices for the treatment of ruptured and unruptured intracranial aneurysms, as well as super-selective embolizations and infusions for the treatment of numerous cerebrovascular and oncologic diseases. The existing evidence for the safety and efficacy of these therapies is encouraging, however, continued evaluation with rigorous, prospective trials is warranted to better understand their durability and long-term benefits.
