Acta Obstet Gynecol Scand. 2004 Jun;83(6):560-2. doi: 10.1111/j.1600-0412.2004.00535.x.


Background: Vaginal hematoma is a rare but painful complication during and after childbirth, with little information in the literature regarding risk factors and management. Aim. To study the risk factors in a national population-based registry.

Setting: All births in Sweden from 1987 to 2000 inclusive.

Methods: Data were analyzed using the Mantel-Haenszel technique, with odds ratio (OR) and 95% confidence interval (CI), adjusting for maternal age, parity and birthweight.

Results: Nulliparity was a strong risk factor (OR 3.63, 95% CI 3.25-4.08), as was maternal age over 29 years and a birthweight exceeding 4000 g. Irrespective of year of delivery the mother stayed an extra 1.3-1.7 days in hospital following this complication.

Conclusion: Risk factors for vaginal hematoma during delivery include primiparity and a maternal age > 29 years.
