The application and uses of telemedicine in vascular surgery: A narrative review

Technological advances over the past century have accelerated the pace and breadth of medical and surgical care. From the initial delivery of "telemedicine" over the radio in the 1920s, the delivery of medicine and surgery in the 21^st century is no longer limited by connectivity. The COVID-19 pandemic hastened the uptake of telemedicine to ensure that health care can be maintained despite limited face-to-face contact. Like other areas of medicine, vascular surgery has adopted telemedicine, although its role is not well described in the literature. This narrative review explores how telemedicine has been delivered in vascular surgery. Specific themes of telemedicine are outlined with real-world examples, including consultation, triaging, collaboration, mentoring, monitoring and surveillance, mobile health, and education. This review also explores possible future advances in telemedicine and issues around equity of care. Finally, important ethical considerations and limitations related to the applications of telemedicine are outlined.
