Splenic torsion and rupture in pregnancy.

Splenic rupture in pregnancy and the puerperium is a rare and potentially catastrophic event. A case of splenic rupture in pregnancy due to partial torsion and internal trauma of a floating spleen is presented, and represents the 89th pregnancy-puerperal report of splenic rupture. Nineteen additional cases have been identified by the authors over the past 20 years. A 20-year review (1967-1986) of clinical presentations, pathogenesis, and therapy are presented.
