Multifetal Pregnancy Reduction and Selective Termination: The Canadian Experience

Objective: To describe the experience of two Canadian referral centres with multifetal pregnancy reduction (MFPR) and selective termination (ST). Methods: Retrospective chart review of all MFPR and ST procedures during the periods from January 1, 1990, to December 31, 1997 (Vancouver), and from September 1, 1995, to December 31, 1997 (Toronto). Outstanding outcome data were obtained by telephone. All women were managed according to standard protocols. Non-parametric analysis of continuous variables and Fisher’s exact test for categorical variables were used. Results: 61 women underwent transabdominal MFPR (n = 44) or ST (n = 17). Median maternal age: MFPR and ST 33.0 years; gestational age at reduction: MFPR 11.4, ST 20.2 weeks; procedure duration: MFPR 4, ST 10 min. 89% MFPR and 12% ST cases followed assisted reproduction. 7% MFPR and 18% ST pregnancies lost
