Management in intractable obstetric haemorrhage: an audit study on 61 cases

Objective: To refine the indications of bilateral hypogastric artery ligation (BHAL) and angiographic selective embolisation (ASE) in intractable obstetric haemorrhage. Design: an audit study. Setting: Tertiary care university hospital. Population and methods: Retrospective analysis of 61 cases of obstetric intractable post partum haemorrhage (PPH) initially managed either by hysterectomy or a conservative approach in a tertiary referral centre between 1983 and 1998. Procedures were reviewed as a primary (P) or secondary (S) attempt to arrest the haemorrhagic process. Results: Ten hysterectomies (5 P, 5 S), 49 BHAL (48 P, 1 S) and 9 ASE (8 P, 1S) were successfully performed in arresting the haemorrhagic process. There were 7 maternal deaths, 5 following hysterectomy and 2 following a conservative approach. Atony of the uterus was the main cause of haemorrhage ( n=21) and genital tract laceration was associated with the worst prognosis. Time-elapse between delivery and surgery appears to be the main prognostic factor. Nine patients became pregnant 1 to 4 years later following a conservative approach. Conclusions: ASE seems to be indicated in haemodynamically stable patients with birth canal trauma or uterine atony and clotting anomalies. BHAL is indicated when haemorrhage occurs after a cesarean section or when the patient is haemodynamically unstable. BHAL should be taught to Junior doctors in an attempt to decrease the number of patients transferred in tertiary referral centers for intractable PPH. This might also decrease the number of hysterectomies in intractable PPH.
