Ankle-Brachial Index (ABI) in Trauma

VASCULARABI Screening in Trauma

Systolic Measurements

Highest Brachial Pressure (Arm)

mmHg

Highest Ankle Pressure (Dorsalis Pedis/PT)

mmHg

Awaiting Pressures

Enter the highest systolic brachial and ankle pressures to calculate the screening index.

Guidelines & Evidence

Verified

Last Review: 2026

When to Use

Blunt extremity trauma with suspected vascular injury (e.g., fractures, dislocations, crush injuries)

Penetrating trauma near major vascular structures without hard signs of vascular injury

Assessment following reduction of dislocations (knee, ankle, elbow)

Post-fracture stabilization to reassess distal perfusion

Polytrauma patients where occult vascular injury is suspected

Gunshot or stab wounds to extremities with equivocal exam findings

Tool	Purpose	Strengths	Limitations
ABI	Screening for arterial injury	Rapid, bedside, non-invasive	Operator dependent, less accurate in shock
Doppler Ultrasound	Flow detection	Detects flow presence	Limited anatomical detail
CT Angiography (CTA)	Definitive diagnosis	High sensitivity/specificity	Requires contrast, time
Physical Exam	Initial screening	Immediate, no equipment	Misses occult injuries

Less reliable in hemodynamically unstable patients

May be falsely elevated in calcified vessels (elderly, diabetics)

Cannot localize site of vascular injury

Does not detect isolated venous injury

Insensitive for intimal injuries without flow limitation

Presence of hard signs of vascular injury (active hemorrhage, expanding hematoma, bruit/thrill, pulseless limb) → immediate operative intervention

Traumatic cardiac arrest or moribund patient

Severe limb destruction requiring immediate amputation
