[Ultrasonographic evaluation of thyroid tissue perfusion in patients with Graves-Basedow disease as preparation for surgery].
The aim of this work was to asses the usefulness of a new colour Doppler ultrasonography technique, namely power Doppler (PD), in the management of thyroid tissue perfusion in patients with Graves' disease before surgery. Forty six patients with Graves' disease treated conventionally with Lugol's solution before the operation were examined with power-Doppler scanner. The distribution of the vascular patterns of both lobes was analysed by computer program. Results were compared with bleeding during surgery subjectively and objectively. The analysis of power-Doppler thyroid perfusion showed significantly higher values of blood flow in patients suffering from Graves disease when compared with control group. Pre-operative preparation with Lugol's iodine decreases parenchymal blood flow. Auscultation of vascular murmur over the gland fading after Lugol's treatment does not always reflect parenchymal high value of blood flow measured by density of microvessels.
