Adjacent to abdominal aorta, inferior vena cava (n=41) | Adjacent to iliac vessels (n=14) | P-value/χ2 | |
Severe symptoms or unstable vital signs n (%) | 10(24.4) | 4(28.6) | 0.096 |
Diameter of sac/cm ( ±s) | 3.81 ± 1.74 | 3.77 ± 2.39 | 0.441 |
hCG before surgery (IU/L) ( ±s) | 40445 ± 30081 | 18202 ± 16681 | 0.027 |
Times of surgery ( ±s) | 1.34 ± 0.62 | 1.57 ± 0.65 | 0.277 |
hCG normalization time after surgery/d ( ±s) | 19.29 ± 8.69 | 16.73 ± 11.1 | 0.134 |
Note:Among the continuous data, only the hCG normalization time after surgery followed a normal distribution. Abdominal RPEP: the sac adjacent to abdominal aorta, inferior vena cava.
Pelvic RPEP: the sac adjacent to iliac vessels.
