The prognostic value of placental protein 5 (PP5) serum levels were compared with ultrasound in the clinical assessment of 26 patients with uterine bleeding at 12-33 weeks of pregnancy. An intrauterine haematoma was found by ultrasound in 16 patients (62%), and in those patients the duration of pregnancy was significantly shorter than in the 10 who did not have a haematoma. Placental abruption ensued in five patients with haematoma, and although the highest serum PP5 level occurred in such a patient, the levels were similar to those in the other patients in whom no abruption was identified. A clinically important finding was that, in placental abruption, a haematoma may accumulate between the fetal membranes and the uterine wall instead of in the retroplacental space. We conclude that ultrasound examination is more effective than PP5 measurement in the assessment of prognosis of patients who bleed during pregnancy.
在对26例妊娠12 - 33周出现子宫出血的患者进行临床评估时，比较了胎盘蛋白5（PP5）血清水平与超声检查的预后价值。超声检查发现16例患者（62%）有子宫内血肿，这些患者的妊娠持续时间明显短于未出现血肿的10例患者。5例有血肿的患者发生了胎盘早剥，虽然胎盘早剥患者的血清PP5水平最高，但这些水平与未发生胎盘早剥的其他患者相似。一个具有临床意义的发现是，在胎盘早剥时，血肿可能积聚在胎膜与子宫壁之间，而非胎盘后间隙。我们得出结论，在评估孕期出血患者的预后时，超声检查比PP5测量更有效。
