ABSTRACT Transarterial embolization (AE) can be a lifesaving procedure for severe hemorrhage associated with pelvic fractures. The purpose of this study was to identify demographic and radiographic findings that predict the need for embolization. We performed a retrospective review of all patients with at least one pelvic fracture and admission to the intensive care unit over a 35-month period. Computed tomography (CT) and pelvic radiographs were reviewed. Patient demographics, outcomes, time to angiography, and whether or not embolization was performed were determined. Statistical analysis was used to determine factors associated with the need for AE. Of the 327 total patients with pelvic fractures, 317 underwent CT scanning. Forty-four patients (13.5%) underwent angiography and 25 (7.6%) required therapeutic embolization. There were 39 total deaths (11.6%) with five deaths related to pelvic hemorrhage (1.5%). Multivariate analysis revealed that age older than 55 years (odds ratio [OR], 1.06; P < 0.001), systolic blood pressure less than 90 mmHg in the emergency department (OR, 11.64; P = 0.0008), and CT extravasation (OR, 147.152; P < 0.0001) were significantly associated with the need for embolization. Contrast extravasation was not present in 25 per cent of patients requiring therapeutic AE. The presence of contrast extravasation is highly associated with the need for pelvic embolization in patients with pelvic fractures, but its absence does not exclude the need for pelvic angiography.

    ABSTRACT: In recent years, combined interventional radiology and operative suites have been proposed and are now becoming operational in select trauma centres. Given the infancy of this technology, this review aims to review the rationale, benefits and challenges of hybrid suites in the management of seriously injured patients. No specific studies exist that investigate outcomes within hybrid trauma suites. Endovascular and interventional radiology techniques have been successfully employed in thoracic, abdominal, pelvic and extremity trauma. Although the association between delayed haemorrhage control and poorer patient outcomes is intuitive, most supporting scientific data are outdated. The hybrid suite model offers the potential to expedite haemorrhage control through synergistic operative, interventional radiology and resuscitative platforms. Maximizing the utility of these suites requires trained multidisciplinary teams, ergonomic and workplace considerations, as well as a fundamental paradigm shift of trauma care. This often translates into a more damage-control orientated philosophy. Hybrid suites offer tremendous potential to expedite haemorrhage control in trauma patients. Outcome evaluations from trauma units that currently have operational hybrid suites are required to establish clearer guidelines and criteria for patient management.

    ABSTRACT: OBJECTIVE. The objective of our study was to evaluate the long-term trends in the use of angiography and embolization for abdominopelvic injuries. MATERIALS AND METHODS. Utilization rates for pelvic and abdominal angiography, arterial embolization, and CT were analyzed for trauma patients with pelvic fractures and liver and kidney injuries admitted to a level 1 trauma center from 1996 to 2010. Multivariable linear regression was used to evaluate trends in the use of angioembolization. RESULTS. A total of 9145 patients were admitted for abdominopelvic injuries during the study period. Pelvic angiography decreased annually by 5.0% (95% CI, -6.4% to -3.7%) from 1996 to 2002 and by 1.8% (-2.4% to -1.2%) from 2003 to 2010. Embolization rates for these patients varied from 49% in 1997 to 100% in 2010. Utilization of pelvic CT on the day of admission increased significantly during this period. Abdominal angiography for liver and kidney injuries decreased annually by 3.3% (95% CI, -4.8% to -1.8%) and 2.0% (-4.3% to 0.3%) between 1996 and 2002 and by 0.8% (95% CI, -1.4% to -0.1%) and 0.9% (-2.0% to 0.1%) from 2003 to 2010, respectively. Embolization rates ranged from 25% in 1999 to 100% in 2010 for liver injuries and from 0% in 1997 to 80% in 2002 for kidney injuries. Abdominal CT for liver and kidney injuries on the day of admission also increased. CONCLUSION. A significant decrease in angiography use for trauma patients with pelvic fractures, liver injuries, and kidney injuries from 1996 to 2010 and a trend toward increasing embolization rates among patients who underwent angiography were found. These findings reflect a declining role of angiography for diagnostic purposes and emphasize the importance of angiography as a means to embolization for management.

    ABSTRACT: Posterior iliac crescent fracture-dislocation is generally considered rotationally unstable and vertically stable. The current study (1) investigated whether vertical instability may occur in posterior iliac crescent fracture-dislocation and (2) analyzed the clinical features of vertically unstable iliac crescent fracture-dislocation as well as treatment strategies. Patients with pelvic fracture who were treated in the authors' department from June 2009 to June 2012 were retrospectively reviewed. This study analyzed the clinical features, including incidence, hemodynamic state, associated injuries, injury severity score, and treatment methods for vertically unstable iliac crescent fracture-dislocation. Four patients had vertically unstable fracture-dislocation, accounting for 12.9% of all iliac crescent fracture-dislocations. All 4 patients were hemodynamically unstable on admission and had complications of associated injuries with a higher injury severity score. In 3 of the 4 patients, iliac crescent fracture-dislocations were reduced via the posterior approach at the initial stage and these patients underwent fixation with a plate. The remaining patient was initially given transcondylar traction because of severe complications and underwent open reduction and internal fixation (ORIF) via a posterior approach at a later stage. The outcomes of all 4 patients were rated as good or excellent by the Kobbe rating system at the last follow-up. Vertical instability may occur in iliac crescent fracture-dislocation. The authors propose ORIF of the fracture-dislocation via a posterior approach. When initial surgery is not possible because of severe associated organ injuries, the authors propose transcondylar traction to allow reduction of the sacroiliac joint and ORIF at a later stage.
