The Authors refer on the validity of echoscopic examination and hCG, progesterone and 17-beta estradiol values in the prognosis of threatened abortion during the first trimester of pregnancy in 62 patients. The echoscopic examination allowed a prognosis to be made in accordance with the clinical evolution of threatened abortion in 90% of the cases; the plasma levels of hCG and progesterone in 87% of the cases; 17-beta estradiol in 83% of the cases. The Authors conclude that the simultaneous assay of hCG, progesterone and 17-beta estradiol plasma levels does not improve the prognostic validity of echoscopy but, in some cases, can provide essential details on the etiology of threatened abortion itself.
作者探讨了超声检查以及人绒毛膜促性腺激素（hCG）、孕酮和17-β-雌二醇值在62例妊娠早期先兆流产预后中的有效性。超声检查能根据90%的先兆流产临床进展做出预后判断；hCG和孕酮血浆水平能在87%的病例中做出判断；17-β-雌二醇能在83%的病例中做出判断。作者得出结论，同时检测hCG、孕酮和17-β-雌二醇血浆水平并不能提高超声检查的预后有效性，但在某些情况下，可以提供关于先兆流产本身病因的重要细节。
