妇科恶性肿瘤早期一般无出血现象,有些恶性肿瘤在发展期间或至晚期常引起难以制止的、致命的大出血。此外,恶性肿瘤手术时,尤其病情较晚者,常因广泛粘连、局部解剖变异、手术野血管多,容易发生出血。在重要血管区手术,更易渗血,甚至发生难以处理的、危及生命的大出血,对此我们必须提高警惕。恶性滋养细胞肿瘤为高度恶性、主要经血道转移的肿瘤,其病理特点为增生的滋养细胞侵犯子宫肌层及血管,并伴有远处转移。转移灶常见出血、坏死及感染,肺转移居首位,其次为阴道转移。阴道转移是
Early gynecological malignancies generally no bleeding, some malignant tumors often lead to hard-to-stop, fatal bleeding in the development period or late. In addition, malignant tumor surgery, especially in later cases, often due to extensive adhesions, local anatomical variations, surgical field more blood vessels, prone to bleeding. We have to be vigilant for surgery in major vascular areas, more bleeding, and even intractable, life-threatening haemorrhages. Malignant trophoblastic tumor is a highly malignant, mainly by the blood-tract metastasis of the tumor, characterized by hyperplastic trophoblast invasion of the myometrium and blood vessels, and associated with distant metastasis. Metastasis common hemorrhage, necrosis and infection, lung metastasis ranked first, followed by vaginal metastasis. Vaginal metastasis is
