Asymptomatic Arterial Injuries
- Non-occlusive asymptomatic vascular injuries
– Dissection – Small pseudoaneurysm – AVF – Isolated tibial thrombosis
- Three series totaling 98 asymptomatic combined arterial
+ orthopedic injuries without hard signs
- Single operative repair (which may not have been necessary)
- Series of 15 asymptomatic combined injuries followed for
6 months

Who Goes First?
- Skeletal repair is priority or selective vascular repair when
ischemia is clinically evident
- Disruption of fresh vascular anastomosis by orthopedic surgeons
during reduction
- Length discrepancy of vascular repair after reducing unstable
skeletal injuries
- Snyder et al
- Combined vascular + orthopedic repair in 29 patients
- Two patients requiring repair at index operation
- Did not effect outcome
- Howe et al
- Combined vascular + orthopedic repair in 21 patients
- No episodes of vascular disruption

Who Goes First?
- Significantly lower amputation rates in those undergoing
revascularization first in comparison to orthopedic repair first
- Lim et al
- McCabe et al
- “Restoration of blood flow should always take priority
- ver skeletal repair’
- Eastern Association for the Surgery of Trauma Practice Guidlines
- Temporary shunting to allow stabilization of unstable fractures
- Immediate definitive arterial repair while skeletal injury is stable and
not significantly displaced

Definitive Repair vs. Shunt
- Physiologic parameters
- Hemodynamic Instability
- Coagulopathy
- Acidosis
- Hypothermia
- Other life threatening injuries requiring urgent
management
- Head injuries, pelvic fractures, etc.
- Major wound contamination
- Extensive soft tissue defects precluding wound coverage
- Requirements for complex repair
- Bypass rather than primary repair
