Abstract
This study was conducted to evaluate the
diagnostic accuracy of power Doppler ultrasonography
(PDU) for differentiating secondary from primary Raynaud’s
phenomenon (RP), and also compared PDU with
nailfold capillaroscopy (NFC) for the assessment of microvascularity
in undifferentiated connective tissue disease
(UCTD) patients with RP. Microvascularity in the nailfold
and finger tip was evaluated using PDU with cold
challenge, and the findings of PDU were classified
according to the qualitative grading system before and after
cold challenge. NFC was performed at the same day in all
persons. The results of PDU were compared with the
clinical, laboratory data, and the findings of NFC. The 14
UCTD patients with RP were included in our study. Seven
patients were suspected of secondary RP in NFC examination,
thus NFC yielded a correct classification into
secondary RP in 50% of the UCTD patients. The PDU
finding of pattern II, which is regarded as the finding of
secondary RP, was observed in 12 UCTD patients with RP.
Thus, PDU yielded a correct classification into secondary
RP in 86% of UCTD patients. In conclusion, we confirmed
that PDU has a higher correct classification rate than NFC
for the diagnosing of secondary RP in UCTD patients. Our
results suggest that PDU has better accuracy than NFC in
differentiating secondary from primary RP, and PDU is
more useful in assessing microvascular abnormalities in
UCTD patients with RP.
