流产的分类Classification of Miscarriage

今天我们要了解的是流产的定义和分类。不管是哪种流产，它的发生对女性的精神心理及身体有着很大的挫伤!

Today we’re gonna look at the declination and classification of miscarriage. No matter what kind of miscarriage, Its occurrence has the very big contusion to the female's mental state and the body!

流产即妊娠不足28周、胎儿体重不足1000g而终止者，都称为流产。

The termination of pregnancy less than 28 weeks and fetal weight less than 1000g are called miscarriage.

1：流产按其发生的时间分：发生在妊娠12周前者，称早期流产，发生在妊娠12周及以后、不足28周者称为晚期流产。早期流产多与免疫、内分泌因素有关，中晚期流产多与子宫，溶血因素有关。

Miscarriage by its time points: called early miscarriage if occurred before 12 weeks, known as late miscarriage if occurred after 12 weeks and less than 28 weeks. Early miscarriage is more of immune and endocrine factors, late miscarriage is more of uterine and hemolysis factors.

2：流产按发生方式分：自然流产和人工流产，自然流产按发生的频率又分为偶发性流产与复发性流产(习惯性流产)，复发性流产指的是同一性伴侣连续发生2次及以上的自然流产。

Miscarriage is divided into natural miscarriage and induced miscarriage according to the way of occurrence, natural miscarriage is divided into spontaneous miscarriage and recurrent spontaneous miscarriage (RSA) according to the frequency of occurrence, RSA refers to spontaneous miscarriage that occurs two or more times with the same partner.

3：按自然流产发生的不同阶段又分为：先兆流产、难免流产、不全流产、完全流产、稽留流产。

4：复发性流产的安太式分法：

Antai’s classification of RSA:

早期原发性复发性流产;

Early primary RSA;

早期继发性免疫性复发性流产(抗核抗体增高);

Early secondary immune RSA (Increased antinuclear antibodies);

晚期原发性复发性流产：多见于宫颈异常或子宫纵膈;

Late primary RSA: more common in cervical abnormalities or the mediastinum;

晚期继发性复发性流产：多见于宫颈松驰、母婴血型不合、宫颈撕裂。
