概括
双胞胎对双胞胎输血综合征 (TTTS) 阶段I患者间歇性动脉缺席或逆转终端透析速度 (AREDV) 在激光手术后具有显著更高的捐赠双胞胎子宫内胎儿死亡 (IUFD) 风险. 这凸显了在TTTS分期和治疗中需要仔细解释AREDV的必要性.
科学领域:
- 周围生理学 周围生理学
- 孕产妇和胎儿医学 孕产妇和胎儿医学
- 胎儿外科手术 胎儿外科
背景情况:
- 双胞胎对双胞胎输血综合征 (TTTS) 影响了9%-15%的单胞胎双胞胎怀孕.
- 昆特罗分阶段系统对TTTS的严重程度进行了分类,I阶段由供体双胞胎的动脉 (UA) 中间歇性缺席或逆转端透析速度 (AREDV) 定义,III阶段由持久的UA-AREDV定义.
- 间歇性与持续性UA-AREDV的解释有所不同,影响了治疗结果.
研究的目的:
- 为了比较阶段I TTTS与间歇性UA-AREDV相比,阶段I TTTS与正常UA波形的激光治疗结果.
- 评估第三阶段TTTS与持续UA-AREDV作为对照组的结果.
- 评估动脉动脉 (AA) 通讯与术后供体死亡之间的关联.
主要方法:
- 对349个带有TTTS的单双子进行了回顾性分析,这些双子接受了激光手术治疗 (2006-2023年).
- 分析了三个组:第一阶段的UA流量正常 (第一阶段正常),第一阶段的UA-AREDV间歇性 (第一阶段间歇性) 和第三阶段的UA-AREDV持续性 (第三阶段).
- 主要结局是捐赠双胞胎子宫内胎儿死亡 (IUFD);动脉动脉 (AA) 通信也被评估.
主要成果:
- 与第一阶段间歇性 (25.0%) 和第三阶段 (29.2%) 组相比,第一阶段正常 (3.0%) 的捐赠IUFD率显着较低 (P<.0001).
- 在第一阶段正常 (97.0%) 与第一阶段间歇性 (75.0%) 和第三阶段 (66.0%) (P<.0001) 之间,双重生存率最高.
- 第一个阶段的间歇性患者与第一个阶段的正常患者相比,患有供体IUFD的风险增加了7倍 (OR 7.23),类似于第三阶段的患者 (OR 7.24). 在I阶段间歇性组 (69.4%) 中,AA通信更频繁,并且独立地与增加的供体IUFD风险 (OR 3.59) 相关.
结论:
- 经过激光手术后,具有间歇性UA-AREDV的TTTSI阶段患者面临着供体IUFD的高风险.
- 存在AA通信也是供体IUFD的一个显著的独立风险因素.
- 这些发现强调了在TTTS管理中准确区分间歇性和持续性UA-AREDV的重要性.

Fetal Circulation

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

Kidney Transplant I: Introduction
60
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...
