Objective
To assess the safety and short-term efficacy of bilateral uterine artery ligation (UAL) via minilaparotomy for the management of heavy menstrual bleeding (HMB).Methods
A prospective study of 30 women with HMB who underwent UAL. The primary outcome was cumulative treatment failure 12 months after the procedure. Treatment failure was defined as the need for hysterectomy during the follow-up period.Results
At 12 months, 6 women had undergone hysterectomy for bleeding, for a cumulative failure rate of 20% (95% CI, 9%-38%). The number of bleeding days was significantly reduced by 11.9 ± 1.5 days (P < 0.001) and hemoglobin level significantly increased by 1.3 ± 0.15 g/dL (P < 0.001). Of the 30 women, 24 (80%) were satisfied with the results. No major complications were reported during the procedure or median follow-up period of 13.2 months.Conclusion
Bilateral UAL is a safe and effective minimally invasive procedure that can provide an alternative treatment for HMB. 相似文献65.

Uterine fibroids are the most common tumours presenting in women. The pathophysiology of fibroids is poorly understood, but disordered angiogenesis and altered smooth muscle cell proliferation are believed to play a role. In this review, current knowledge of both of these processes will be summarized. Differences between 'normal' adjacent myometrium and fibroid tumours within the same uterus are outlined. Exploiting these differences represents one of the best opportunities for the development of medical treatments that target fibroid tissue selectively. 相似文献

A 65-year-old patient with endometrial adenocarcinoma underwent hysterectomy. Pathological examination of the right ovary revealed a coexisting stromal luteoma. The possible relationship between the two neoplasms as well as the intriguing pathogenesis and controversial nomenclature of ovarian steroid cell tumors are discussed. The incidental discovery of a stromal luteoma in a total hysterectomy specimen removed for endometrial carcinoma raises interesting questions about the perceived innocuous nature of these rare lipid cell tumors. 相似文献
