Abstract：
OBJECTIVE: To evaluate hemostatic efficacy, complications, and subsequent pregnancy outcomes in women with placenta previa who underwent combined vertical compression sutures in the lower uterine segment and intrauterine balloon tamponade (Hot-Dog method) to achieve hemostasis after cesarean section.
METHODS: We retrospectively reviewed data for 117 women with singleton pregnancy diagnosed with placenta previa who underwent cesarean section between 29 and 38 weeks\' gestation. Treatments were as follows: (1) conventional-intravenous oxytocin administration after placental detachment and suturing of bleeding points at the detachment site as needed (conventional group) (n = 47). (2) Intrauterine balloon tamponade alone (balloon group) (n = 41). (3) Vertical compression sutures + intrauterine balloon tamponade (Hot-Dog group) (n = 29).
RESULTS: The placenta accreta spectrum prevalence was significantly higher in the balloon and Hot-Dog groups versus the conventional group. The prevalence of anteriorly located placenta was significantly higher in the Hot-Dog versus balloon groups. Intraoperative and total blood loss were significantly higher in the Hot-Dog versus conventional groups. Postoperative blood loss was significantly lower in the Hot-Dog versus balloon groups. Fewer additional procedures for managing postoperative hemorrhage were required in the Hot-Dog versus conventional and balloon groups. The number of subsequent pregnancies in the conventional, balloon, and Hot-Dog groups was 11 (23.4%), 8 (19.5%), and 4 (13.8%), respectively; all resulted in live births at term without serious obstetric complications.
CONCLUSIONS: The Hot-Dog method is a straightforward and safe hemostasis technique for placenta previa that preserves fertility and controls severe bleeding.

摘要：
目的：评价止血效果，并发症,前置胎盘行子宫下段垂直压迫缝合联合宫内球囊填塞（热狗法）以实现剖宫产后止血的妊娠结局。
方法：我们回顾性分析了117例诊断为前置胎盘的单胎妊娠妇女的数据，这些妇女在妊娠29至38周之间进行了剖宫产。治疗方法如下：（1）胎盘脱离后常规静脉给予催产素，并根据需要在脱离部位缝合出血点（常规组）（n=47）。(2)单独宫内球囊填塞(球囊组)(n=41)。(3)垂直压迫缝线+宫内球囊填塞(热狗组)(n=29)。
结果：球囊组和热狗组的胎盘植入谱患病率明显高于常规组。与气球组相比，热狗组的前置胎盘患病率明显更高。与常规组相比，热狗组的术中失血量和总失血量明显更高。热狗与气球组的术后失血量明显较低。与常规组和球囊组相比，热狗组需要更少的其他手术来管理术后出血。传统的后续怀孕次数，气球,热狗组为11组(23.4%)，8（19.5%），和4（13.8%），分别；所有结果都是足月活产，没有严重的产科并发症。
结论：热狗方法是一种简单而安全的前置胎盘止血技术，可以保留生育能力并控制严重出血。
