Assessment of lower extremity ischemia using smartphone thermographic imaging.

Conventional diagnostic modalities for assessing arterial circulation or tissue perfusion include blood pressure measurement, ultrasound evaluation, and contrast-based angiographic assessment. An infrared thermal camera can detect infrared radiation energy from the human body, which generates a thermographic image to allow tissue perfusion analysis. We describe a smartphone-based miniature thermal imaging system that can be used as an adjunctive imaging modality to assess tissue perfusion.

Treatment outcomes and lessons learned from 5134 cases of outpatient office-based endovascular procedures in a vascular surgical practice.

Introduction The office-based endovascular facility has increased in number recently due in part to expedient patient experience. This study analyzed treatment outcomes of procedures performed in our office-based endovascular suite. Methods Treatment outcomes of 5134 consecutive procedures performed in our office-based endovascular suites from 2006 to 2013 were analyzed.
