Matsubara-Yano suture: a simple uterine compression suture for postpartum hemorrhage during cesarean section.

AIMS: The aims of this study were to clarify: (i) the effectiveness of Matsubara-Yano uterine compression suture (MY) to achieve hemostasis in the presence of postpartum hemorrhage (PPH) during cesarean section, (ii) the type of PPH for which MY is effective, (iii) post-operative complications of MY, and (iv) outcomes of pregnancy after MY.

METHODS

This retrospective observational study was performed using medical records of patients for whom MY had been performed between January 1, 2009 and December 31, 2017.

RESULTS

MY was performed for 50 patients, with hemostasis achieved in 46 (92%). The other four (8%: 4/50) patients required transarterial embolization or hysterectomy. Of these four, three patients had placenta accreta spectrum (PAS) disorder-related bleeding. Post-operative complications were observed in three (6%: 3/50) patients, with all showing intrauterine infection. All three patients recovered solely with antibiotics. Eight pregnancies were confirmed (five livebirths, two spontaneous abortions in the first trimester, and one case of ongoing pregnancy). Of the five livebirths, one resulted in cesarean hysterectomy due to placenta previa with PAS disorders.

CONCLUSIONS

MY had a hemostatic effect on PPH. All cases except one with hemostatic failure were associated with PAS disorders, indicating that the hemostatic rate was lower in those with PAS than non-PAS disorders.
