To compare the application value of temporary internal iliac artery occlusion and temporary abdominal aorta occlusion in caesarean delivery for patients with pernicious placenta previa.

A total of 24 patients with pernicious placenta previa admitted to and treated at our hospital (2015.10—2016.8) were recruited in this study. After fetal head delivered, temporary internal iliac artery balloon occlusion was placed in 12 patients (TIIABO group), and temporary abdominal aorta balloon occlusion was placed in another 12 patients (TAABBO group). Following that, the placental separation and suture at bleeding site were performed. Clinical efficacy and complication occurrence between two groups were compared.

Balloon placement time [21 (2.5, 30.2) min] and radiation amount [23.85 (19.95, 25.45) mGy] in TIIABO group were all higher than those in TAABBO group [4 (3.0, 9.5) min; 1.21 (0.90, 2.51) mGy], and the difference was statistically significant (Z:4.18, 4.16, P <0.01). No statistical significance was observed in bleeding amount between two groups [800 (700, 1500) ml vs. 750 (550,1000) ml, Z=0.91, P=1.00].

Both of the two temporary balloon occlusion methods significantly reduce the bleeding amount during caesarean delivery and as well as the uterectomy rate. Temporary abdominal aorta occlusion is superior to temporary internal iliac artery occlusion in terms of balloon placement time, which is shorter, low radiation and less bleeding amount.
