Pulsed Doppler Flow Measurements in patients suffering from collum cancer using a coloured pulsed Doppler technique measurements of blood flow of the uterine artery were performed in a group of 35 patients suffering from an inoperable collum cancer (stage II and III according FIGO) and compared with a collective of 30 healthy women with normal anamnesis. The mean pulsatility index (PI) was significantly lower in the sick group (stage II 1.6 +/- 1.17, stage III 0.76 +/- 0.21) than in the healthy group (PI = 3.18 +/- 0.99) (p less than 0.01). In 14 subjects of the last group there was no significant difference in PI between the left and right uterine artery (left: PI 2.81 +/- 0.83), right: PI 2.78 +/- 0.76).
