The goal of this observational study is to establish a prospective multicenter registry of patients undergoing intracranial stenting for ischemic strokes caused by medically refractory ICAD. The study aims to evaluate current practice patterns, periprocedural outcomes, and delayed outcomes.
Researchers will collect demographic and procedural data from patients who undergo intracranial stenting after having an ischemic stroke caused by medically refractory ICAD.

The purpose of this study is to study how well using a powdered form of the antibiotic, vancomycin, inside the surgery wound prevents infection in patients undergoing instrumented spinal surgery for traumatic injury to the back.
Vancomycin is approved by the United States Food and Drug Administration (FDA) for treating certain kinds of bacteria. It is also used to prevent infections of the surgery site.
This will be a study in which the experimental treatment is compared to a standard (control) treatment. It will be prospective in nature, meaning that it will follow patients forward in time, and it will consist of a randomization process to determine who will receive the experimental treatment versus the standard (control) treatment.
The study will take place at Regional Medical Center (The MED). 140 subjects will be participating in this study.
The investigators hypothesize that the topical use of powder vancomycin will decrease the rate of surgical site infection.
