Surveillance of twin pregnancy with umbilical arterial velocimetry.

A continuous-wave Doppler system and a spectrum analyzer provide the tools for the measurement of systolic-diastolic velocity wave ratios in the umbilical arteries. In twins, each umbilical cord can be studied without imaging the fetuses. Results were tabulated by taking the average difference in the ratios between each fetus and plotting these values against the neonatal weight differences. In 43 twin pregnancies, the data revealed that ratio differences between fetuses that averaged 0.4 or more was predictive of a weight difference of greater than 349 gm. The sensitivity was 73% and specificity 82%. Two cases of twin transfusion syndrome were recognized by the simultaneous presence of high- and low-resistance values.

RO-TAGE biopsy. An improved method of endocervical evaluation.

The colposcopic management of patients with abnormal Papanicolaou smears relies on correlating the examination findings with the cytology and biopsy results. Failure to adequately sample the endocervical canal introduces a possible source of error and could allow an invasive lesion to be missed. In 300 patients subjected to both endocervical curettage and RO-TAGE biopsy (Proto Med Incorporated, Boulder, Colorado), significantly fewer inadequate samples were obtained with RO-TAGE biopsy (1%) or the use of both methods (0.3%) than with curettage alone (4.3%). Therefore, we conclude that RO-TAGE biopsy should be added to every colposcopic examination.

The "unsatisfactory" colposcopic examination.

One hundred nine of 735 patients (14.8%) referred for colposcopic evaluation had "unsatisfactory" examinations. Of 108 women 40 years of age or over, 81 had unsatisfactory examinations (45%) as compared with 28 of 555 women under 40 (5%) (p less than 0.001). Thirty-five of the 109 patients with unsatisfactory examinations (32%) had had prior cautery or conization as compared with 141 of 626 in the "satisfactory" group (22.5%) (p less than 0.04). Seventy-three of the 99 patients on whom follow-up information was obtained had cervical conization biopsies for final diagnoses. Correlation with previously performed endocervical curettage and colposcopically directed biopsies was poor. Careful correlation of cytology, colposcopy and histopathology is necessary to achieve optimal results in the management of patients with unsatisfactory examinations. Diagnostic conization continues to play an important role in the management of patients with abnormal cervical cytology.
