Assessing hemodynamic changes in diabetic patients with and without peripheral arterial disease using dynamic vascular optical spectroscopy

Hemodynamic parameters measured by DVOS during thigh venous occlusion differ significantly between diabetic patients with and without PAD. Our findings suggest that 60-mmHg occlusion is more effective than 100 mmHg for eliciting PAD-sensitive hemodynamic parameters. These results highlight the potential sensitivity of DVOS to PAD-related vascular impairment during low-pressure thigh occlusion.
