“…Given these highly divergent conditions, the applicability of ultrasonic cavitation research to blast injury should be considered conservatively. One argument for utilizing ultrasonic or commercial extracorporeal shock models, is to examine microscopic level injury that a more realistic blast model is not well-suited to produce (51). However, the results from ultrasonic microscopic models may not be generalizable to blast injury, due to the different focal areas of the shock wave exposure, overpressures, and pressure durations.…”

Cavitation has gained popularity in recent years as a potential mechanism of blast-induced traumatic brain injury (bTBI). This review presents the most prominent debates on cavitation; how bubbles can form or exist within the cerebrospinal fluid (CSF) and brain vasculature, potential mechanisms of cellular, and tissue level damage following the collapse of bubbles in response to local pressure fluctuations, and a survey of experimental and computational models used to address cavitation research questions. Due to the broad and varied nature of cavitation research, this review attempts to provide a necessary synthesis of cavitation findings relevant to bTBI, and identifies key areas where additional work is required. Fundamental questions about the viability and likelihood of CSF cavitation during blast remain, despite a variety of research regarding potential injury pathways. Much of the existing literature on bTBI evaluates cavitation based off its prima facie plausibility, while more rigorous evaluation of its likelihood becomes increasingly necessary. This review assesses the validity of some of the common assumptions in cavitation research, as well as highlighting outstanding questions that are essential in future work.
