Blazing the trail! Commentary on "Intra-arterial lidocaine administration in middle meningeal artery for short-term treatment of subarachoid hemorrhage-related headaches" by Qureshi et al.

In their recently published INR study, Qureshi et al. present their results on intra-arterial lidocaine administration in the middle meningeal artery for the short-term treatment of subarachnoid hemorrhage (SAH)-related headaches. The authors demonstrate that their proposed intra-arterial treatment consistently alleviates headaches in patients with SAH. The purpose of this commentary is to commend the authors on their paper and the notable results they have achieved. It is always pleasant to encounter studies that not only make it to the "Latest Online" section of neurointerventional journals but also push the boundaries, advancing our understanding and care for patients in the most meaningful ways. There is no doubt that our field has witnessed remarkable progress and an expanding spectrum of interventions that endovascular neuroservices can offer. Several therapeutic approaches have emerged from similarly constructive articles, including intra-arterial chemotherapy for malignant cerebral tumors, innovative treatments for cerebrospinal fluid-venous fistulas, hydrocephalus, and chronic subdural hematomas, as well as the implantation of brain-computer interface devices.
