Evaluation of usefulness of blood flow measurement device
- Conditions
- arteriosclerosis obliterans (ASO) or suspection of the ASOarteriosclerosis obliteransI7020
- Registration Number
- JPRN-jRCTs032200072
- Lead Sponsor
- Horinaka Shigeo
- Brief Summary
Flow volumes measured by the electrical impedance plethysmography (EIP) of the lower extremity in the venous occlusion principal and by the doppler duplex ultrasound in the popliteal artery were well correlated. EIP might be able to measure whole lower extremity arterial flow including collateral flow in patients with lower extremity artery disease (LEAD). EIP reflected LEAD more significantly than the Doppler ultrasound method.
