Resumen
Objetivo. Avaliar os efeitos da histerectomia total abdominal (HTA) sobre o fluxo sangüíneo ovariano, em mulheres no menacme, por meio da dopplervelocimetria e ultra-sonografia transvaginal. Pacientes e Métodos. Estudou-se, prospectivamente, 61 mulheres, 40 anos, divididas em: G1, 31 pacientes submetidas à HTA e, G2, 30 mulheres normais. Critérios de inclusão: eumenorreicas, ovulatórias, não obesas ou fumantes, sem cirurgias ou patologias ovarianas prévias. Avaliou-se o fluxo sangüíneo das artérias ovarianas, inicialmente e aos 6 e 12 meses, pelo índice de pulsatilidade (IP) na dopplervelocimetria e o volume ovariano pela ultra-sonografia transvaginal (US). Para análise estatística empregou-se Teste t de Student, Análise de Perfil, Teste de Friedman e Teste de Mann-Whitney. Resultados. Na comparação estatística inicial os grupos foram homogêneos. Nas pacientes submetidas à histerectomia, aos 6 e 12 meses, observou-se aumento do volume ovariano ao US e diminuição do IP ao doppler (p<0,05), quando confrontadas ao controle. Aos 12 meses, em 8 das 31 pacientes pós HTA (25,5%) verificou-se cistos ovarianos, de aspectos benignos. No grupo controle não alterou nenhum desses parâmetros. Conclusão. A redução do índice de pulsatilidade na doplervelocimetria das artérias ovarianas sugere aumento do fluxo sangüíneo ovariano pós histerectomia total abdominal em mulheres no menacme.

EFFECT OF TOTAL ABDOMINAL HYSTERECTOMYON OVARIAN BLOOD SUPPLY IN WOMEN OF REPRODUCTIVE AGE
Abstract
Objective: To evaluate the effect of total abdominal hysterectomy on ovarian blood supply in women of reproductive age, using transvaginal color doppler.Patients and Methods: A prospective study on 61 women, age 40 years, was distributed in: G1, 31 patients submitted to hysterectomy and, G2, 30 normal women. Criteria of inclusion: normal ovarian function at baseline, normal body weight, without tobacco exposition, no history laparotomy or ovarian pathology. The Pulsatility Index (PI) realized by the doppler of ovarian arteries and the ultrasonography transvaginal measures of the ovarian volume were performed in 3 moments: baseline, 6 and 12 months.Results: At baseline the groups were homogeneous. In the patient hysterectomized group, with 6 and 12 months, it was observed increase of the volume of the ovaries and decrease of PI (p<0,05). At the end of the study, among the patient hyterectomized, 25,5% (8/31) of them presented benign ovarian cysts. While in the control group it was not observed alteration of any appraised parameter.Conclusion: The decrease of Pulsatility Index by the doppler of ovarian arteries suggest increased ovarian blood supply after total abdominal hysterectomy in women of reproductive age.
