Imaging and endovascular management of traumatic pelvic fractures with vascular injuries

Outcomes in Blunt vs Penetrating Pelvic Vascular Injuries

OBJECTIVES

The purpose of this study is to determine if there is a difference in outcomes for patients with blunt and penetrating vascular injuries of the pelvis.

METHODS

Data were abstracted from the Trauma Quality Improvement Program database from 2011 to 2015. Patients >18 years with hypogastric, iliac, uterine, or ovarian arterial or venous injuries were included. Individuals with an AIS head or chest score >3 were excluded.

RESULTS

Of the 2559 patients included, the mean age was 43 years (±19), 75.25% were male, and 32.6% had a comorbidity. 64.9% presented with blunt injury (mean ISS of 23 (±12)). 74.9% experienced a complication. The median hospital length of stay (LOS) and ICU LOS were 10 days and 4 days, respectively. 6.7% had an adverse discharge. Mortality occurred in 8.3%. On bivariate analysis, patients who sustained blunt trauma were older (51 vs 31 years), female (32.7% vs 10.1%), had a higher ISS (25.71 vs 17.65), and had a longer hospital LOS (16.65 vs 13.88). Patients with penetrating trauma had an increased chance of complications (78.4% vs 73.0%) and mortality (10.7% vs 7.0%). Multivariate analysis revealed in patients with blunt injuries have more complications (OR: 1.950 CI: 0.886-4.291 P = .097), a lower ISS (OR: 0.919, CI: 0.908-0.930, P < .001, were more likely to have an adverse discharge (OR: 2.05, CI: 1.62-2.60, P = .000), and had a higher risk of mortality (OR: 4.08 CI: 2.78-6.41 P < .000).

CONCLUSION

Patients with blunt pelvic vessel injuries are at risk for an increased number of complications and have a higher risk of mortality. Those who survive are more likely to have an adverse discharge.

In-hospital outcomes of patients with non-iatrogenic civilian vascular trauma

Background: Morbidity, lesion pattern, management and short-term outcomes of civilian vascular trauma are rarely evaluated. Therefore, analysis of in hospital results in patients with non-iatrogenic vascular trauma in a tertiary referral hospital was performed. Patients and methods: Retrospective evaluation of patients with vascular trauma from 2007-2017 was done. 48 patients (34 male, 14 females, mean age 56 years) were included. Excluded were patients with iatrogenic vascular complications. Major cause of vascular trauma were traffic accidents in 43.8 %, fall from great heights in 27.1 %, sport and home related injuries in 16.8 %, suicidal injuries in 4.2 % and gunshot wounds in 2.1 % (other 6.3 %). 60.4 % of patients presented with blunt, 39.6 % of patients with penetrating vascular trauma. More than half of the cases included polytraumatized patients (54.4 %). Results: Most commonly affected were the popliteal (25.0 %) and the axillar artery (18.8 %). Aortic injuries were present in 14.6 % of cases, whereas the femoral and subclavian artery were involved in 12.6 % and 10.4 %. Vascular reconstruction was performed by interposition graft in 45.9 %, direct suture in 18.8 %, patchplasty in 10.4 %, ligation in 12.4 %, and implantation of stentgraft in 12.5 %. Postoperative complication rate was 54.2 %. Rate of in-hospital major amputation was 14.6 % and in-hospital mortality was 14.6 % as well. Comparison between blunt and penetrating trauma as to postoperative complication (p = 0.322), blood transfusion (p = 0.452) and amputation (p = 0.304) showed no significant differences, whereas lethality in blunt trauma was 20.6 % vs. 5.2 % in penetrating trauma. Injury severity score (ISS) was significantly elevated for blunt trauma patients (mean ISS Score blunt 32 vs 21 penetrating, p = 0.043). Conclusions: The majority of vascular lesions is caused by blunt trauma. Blunt lesions do also show a severe injury pattern, compared to penetrating trauma, and the complication rate remains high. However, by means of vascular reconstruction, limb salvage is feasible in a high percentage of cases.
