Abstract
To evaluate efficacy and outcome of embolisation following pelvic ring injuries in patients presented with ongoing hypovolaemic shock.
Between 2000 and 2003, 200 poly-trauma patients presented in our institutions following pelvic ring injuries. Those with ongoing hypovolaemic shock who were treated within 24h of admission with embolisation were included in this study. Demographics, mechanism of injury, ISS, type of pelvic ring fracture, arterial source of bleeding, hours from injury to embolisation, and outcome were all recorded prospectively. Out of the 200 treated in our institutions 17 (8.5%) underwent angio-embolisation. The mean age of the patients was 37 (14-70) and the mean ISS was 29. Distribution of pelvic ring injuries included: 3LC, 7APC, 7VS. The mean time from injury to embolisation was 15 hours. 8/17 patients were initially treated with an external fixator.
The distribution of arterial injuries was: 7 superior gluteal arteries, 8 internal iliac arteries, 1 obturator artery and 1 internal pudental artery. The mean number of units transfused prior to embolisation was 22 (range 6-50). Mortality rate was 4 (23%) out of 17 embolised patients. Angio-embolisation for pelvic ring injuries occurred in 8.5% of our study population.
This study indicates that only a small proportion of patients required embolisation secondary to arterial bleeding. The overall survival rate was in accordance to published international experience. Embolisation should be considered as a valid adjunct in some selected group of patients with pelvic fractures where ongoing bleeding refractory to other treatment modalities is present.
