INTRODUCTION: Extreme cold environments impose unique constraints on the delivery of image-guided and interventional care due to hypothermia-associated coagulopathy, altered drug metabolism, impaired operator performance, and temperature-sensitive imaging and device systems. These challenges are particularly relevant to military operations in polar and austere settings, where evacuation may be delayed, and medical capability must be delivered with limited infrastructure.
MATERIALS AND METHODS: This work presents an operationally focused review of the physiologic effects of cold exposure, imaging system limitations, and device performance considerations relevant to image-guided and interventional care. Available evidence regarding portable imaging platforms, material behavior at low temperatures, and procedural feasibility in cold environments was synthesized to assess realistic capability sets for austere and expeditionary settings.
RESULTS: Portable ultrasound emerged as the most reliable imaging modality for diagnosis and procedural guidance in low-temperature environments. Cold exposure was associated with stiffening of medical polymers, increased glove failure, and accelerated battery degradation, emphasizing the need for insulated storage, device warming strategies, and adapted workflows. Frostbite represents the clearest clinical scenario in which angiography and catheter-directed therapy may influence outcomes, particularly when evacuation or surgical intervention is delayed. Hypothermia-associated coagulopathy, altered sedation pharmacokinetics, and operator performance degradation together create a compounded procedural risk environment.
CONCLUSIONS: Operational frameworks for image-guided and interventional care in extreme cold must integrate shelter capability, power management, telemedicine support, and training that accounts for cold-related cognitive and motor impairment. Although significant gaps remain in interventional radiology-specific device testing, sedation pharmacology, and workflow optimization, existing evidence supports a focused, capability-based approach to expanding image-guided and minimally invasive care in extreme cold environments relevant to future military operations.
