子宫肌瘤可以与妊娠同时存在。我科自1984年1月到1992年7月,共收治子宫肌瘤656例,其中合并妊娠者60例,其发生率为9.14％,较文献报道的0.5％～1％为高。但实际上妊娠合并肌瘤的发生率较上述数字高,因为很多孕产妇肌瘤小,又无临床症状,在妊娠和分娩进程中被漏诊。有的小型肌瘤仅在剖宫产时偶然被发现。在656例子宫肌瘤中经临床或术后病理学检查确诊有红色变性者23例,占3.51％,较Faulkner估计肌瘤伴红色变性发生率约7％～8％为低。其中因妊娠合并子宫肌瘤伴红色变性者仅8例,只占肌瘤合并妊娠患者的13.33％,较曹斌融报道40％低。肌瘤红色变性(red degeneration)又称肉样变性 Uterine fibroids and pregnancy can exist at the same time. Our department from January 1984 to July 1992, a total of 656 cases of uterine fibroids, including 60 cases of pregnancy, the incidence was 9.14%, higher than the reported 0.5% to 1%. However, in fact, the incidence of pregnancy complicated with fibroids than the above figures, because many pregnant women with small fibroids, but no clinical symptoms, missed during the pregnancy and childbirth. Some small fibroids only occasionally found during cesarean section. In 656 cases of uterine fibroids by clinical or postoperative pathological examination confirmed red degeneration in 23 cases, accounting for 3.51%, compared with Faulkner fibroids with red degeneration incidence of about 7% to 8% is low. Among them, 8 cases of pregnancy with uterine fibroids with red degeneration only accounted for 13.33% of patients with fibroids complicated pregnancy, compared with 40% reported by Cao Bin.
