Abstract
Background: The association between pelvic fracture pattern and the need for pelvic arterial embolization remains controversial. To address this issue, a study of the experience at Auckland Hospital was undertaken. Methods: Review was undertaken of a trauma database, blood bank database, patient records and pelvic radiographs. Of the 364 pelvic fracture patients admitted over a 4‐year period, 76 were transfused with 6 or more units of blood in the first 24 h and these constitute the study population. Results: Embolized patients were older (median age 42 vs 29.5 years; P < 0.05) and had a higher abbreviated injury score for the pelvic girdle (median 3 vs 2; P < 0.05) compared to non‐embolized patients. Revised trauma score (median 7.69 vs 7.55), injury severity score (median 29 vs 30.5), morbidity (55 vs 39%) and mortality (45 vs 32.1%) rates did not differ significantly between embolized and non‐embolized groups, respectively. The median blood transfusion requirement in the first 6 h from injury was 14 units in embolized and 8 units in non‐embolized patients (P = 0.005). Embolization was required in 12 of 27 (44.4%) patients with fracture patterns indicative of major pelvic ligament disruption, whereas seven of 38 (18.4%) patients without these fracture patterns required embolization (P < 0.05). Conclusions: The need for pelvic embolization correlated with fracture patterns that indicated major ligament disruption, although the relationship was not sufficiently strong to warrant change to current indications for pelvic angiography.
