Angioembolisation for arterial haemorrhage related to pelvic ring injury.

Introduction: Haemorrhage related to pelvic fractures has been associated with mortality rates of up to 50%. Angioembolisation for the management of pelvic haemorrhage was performed as early as 1972; however, there remains uncertainty over its exact use, timing and priority as a component of modern pelvic management protocols. Methods: We retrospectively analysed cases of angioembolisation for arterial haemorrhage related to pelvic ring fractures at a level 1 trauma centre. Patient demographics were assessed as well as the time taken to reach the interventional radiology (IR) suite from the time of trauma and also arriving at the emergency room (ER). Other factors analysed included the volume of blood products consumed and fracture pattern. Results: Fifty‐four patients received pelvic angiography for pelvic ring injuries between 2006 and 2021. The average age was 45.1 (20.5) years, with the male to female ratio 2.4:1. Forty (74.1%) of these patients had embolisation to actively bleeding pelvic arterial vessels. Median time to the IR was 4.4 [IQR 3.1–8.1] hours from time of trauma and 2.5 [IQR 2.1–4.2] hours from arrival to ER. The overall mortality rate was 18.5% and the median amount of blood transfused was 4584 mL [IQR 1643.5–8026.5]. In the subset of embolised patients (n = 40), mortality rate was 10% and there was an inverse association between time from ER to IR and volume of blood product consumption (P = 0.024). Conclusion: Angioembolisation is a life‐saving intervention in very severely injured patients and is growing in popularity as a component of modern pelvic trauma management protocols.
