Background:
The B-Lynch uterine suture brace has been used for the surgical treatment of postpartum hemorrhage. To date, no complications of this procedure have been reported. We describe B-Lynch suture erosion through the uterine wall identified at a 6-week postpartum visit.
Case:
A 19-year-old primigravida underwent a primary low transverse cesarean section at term for arrest of descent. The surgery was complicated by postpartum hemorrhage secondary to uterine atony unresponsive to medical management. The patient underwent successful placement of a B-Lynch suture using delayed, absorbable suture for control of the hemorrhage and had an uneventful postoperative course. At her 6-week postpartum examination, she was found to have the suture protruding from the uterine cervical os. The suture was removed in its entirety without difficulty. Follow-up sonohysterography at 6 months identified a small defect in the anterior wall of the lower uterine segment, corresponding to the probable site of suture erosion.
Conclusion:
Erosion of suture through the uterine wall can be a complication of the B-Lynch uterine suture brace. Delayed, absorbable suture is less desirable than absorbable suture for this procedure due to the risk of erosion through the uterine wall.
