Abstract

Purpose: Peri-operative major arterial haemorrhage after revision total hip arthroplasty (RTHA) is an odd but limb- and life-threatening complication. In this retrospective analysis, we sought to determine the prevalence of such injuries requiring selective catheter embolization or bypass after RTHA and to evaluate the associated mortality rate.

Methods: Between 1995 and 2016, 2524 RTHAs were performed at a high-volume centre (1031 one-stage revisions, 1370 two-stage revisions and 123 resection arthroplasties). Throughout this period, nine patients presented with signs of persistent bleeding unaddressed during index surgery (9/2524; 0.35%), causing haemodynamic instability. All patients underwent angiographic exploration within the first 24 post-operative hours. Angiography evidenced four cases of bleeding pseudoaneurysms (three of them related to the common femoral artery and one to the medial circumflex femoral artery) and five cases of direct lacerations (one case in the inferior epigastric artery, one in the hypogastric artery, one in the external iliac artery, one in the popliteal artery and another in the superior gluteal artery).

Results: Six cases underwent selective percutaneous angiographic embolization with gelatin microspheres, obtaining immediate haemodynamic stabilization; whereas three cases required a further bypass surgery with synthetic graft. Of the former group, four patients had an uneventful evolution, while two died at a mean of 49 days after surgery due to multi-organ failure (MOF). Two cases of the bypass group died because of MOF at a mean of 22 days. Overall mortality rate was 44%.

Conclusions: The overall risk of arterial injury associated with RTHA was low. However, recognition of such a complication is imperative since it was associated with a high mortality rate.
