Raynaud's phenomenon in arterial occlusive disease

|August 1, 1985
Summary
Measuring digital blood pressure effectively identifies arterial occlusive disease and Raynaud's phenomenon. Low digital pressures indicate cold sensitivity, while normal pressures suggest no obstruction.
Area of Science:
- Vascular Medicine
- Diagnostic Tools
Background:
- Arterial occlusive disease affects digital circulation.
- Raynaud's phenomenon is characterized by exaggerated vasoconstriction.
- Accurate assessment of digital blood pressure is crucial for diagnosis.
Purpose of the Study:
- To correlate digital blood pressure measurements with Raynaud's phenomenon.
- To assess the diagnostic value of digital pressures in arterial occlusive disease.
- To evaluate the relationship between digital pressures and angiographic findings.
Main Methods:
- Photoelectric plethysmography used to measure systolic blood pressure in all fingers.
- Study conducted on 22 hands with diagnosed arterial occlusive disease.
- Correlation analysis performed between digital pressures, cold sensitivity, and angiographic obstruction.
Main Results:
- Significantly lowered digital pressures observed in 93% of fingers with cold sensitivity.
- Normal finger pressures recorded in 97% of fingers without Raynaud's phenomenon.
- Digital blood pressures were consistently normal in cases of unilateral arterial obstruction.
Conclusions:
- Digital blood pressure measurement is a highly sensitive indicator for arterial occlusive disease and Raynaud's phenomenon.
- Normal digital pressures can help rule out significant digital artery obstruction.
- This non-invasive technique aids in the clinical evaluation of peripheral vascular conditions.
