Aim

We analysed our limb salvage outcomes in patients who presented with extremity vascular trauma.

Material and methods

Place of study: Kauvery hospital, Trichy

Duration: 4 years (March 2019–March 2023)

Type: Retrospective analysis

Total number of patients: 82.

Results

1. Demographics

Adults-69

Total (M: F=64:5)

extremity-vascular-trauma-1

Paediatric – 13

Paediatric (M: F=10:3)

extremity-vascular-trauma-2

2. Mode of injury/investigation

extremity-vascular-trauma-3

3. Timing of surgery from presentation

extremity-vascular-trauma-4

4. Vascular injury/Vessel involved

Upper limb – 36

Lower limb – 46

5. Vascular procedure Performed

Interposition vein graft – 68 patients (82%)

Primary repair – 5 patients (6%)

Fasciotomy – 52 patients (63%)

Amputation – 8 (10%) Primary-5, Secondary-3

Ligation – 4 (5%)

6. Associated injuries

Skeletal fractures (66%)

  1. Compound – 26 patients
  2. Simple – 14 patients
  3. Supracondylar – 14 patients

Other injury

  1. Bladder – 2 patient
  2. Nerve – 9 (median nerve most common)

7. Associated procedures

 

Primary ortho procedure – 54

K wire 5
ORIF 15
Closed reduction 4
External fixator 30

Plastic surgery procedure – 44

SSG 24
Tendon and Nerve repair 12
Flap cover 6
Brachial plexus exploration 2

8. Limb Savage vs Amputation

extremity-vascular-trauma-5

9. Mortality – 3 patients (3.6%)

  1. Patient 1 and 2 run over by bus- multiple long bone injury with pelvic and perineal injury – lost to sepsis.(one was doctor)
  2. Patient 3- delayed presentation – crush injury – debridement with vascular repair and free flap- blow out on day 7 secondary to infection

Discussion

PROOVIT Registry

  1. The American Association for the Surgery of Trauma Prospective Observational Vascular Injury Treatment (PROOVIT) registry:
  2. Multicenter data on modern vascular injury diagnosis, management, and outcome
  3. A total of 542 injuries from 14 centers (13 American College of)
  4. Surgeons verified Level I and 1 American College of Surgeons verified
  5. Level II) have been captured since February 2013.
  6. Data for 1 year and 6 months.

Kauvery Hospitals (%)

PROOVIT registry (%)

Male 91 70.5
Blunt injuries 82 47
Extremity Vascular injury (n=82) 93 44
Skeletal injury 66 NA
Hypotension 16 11.8

Injury pattern Transection 42 24.3
Occlusion 48 17.3
Ligation (Vein and Pseudo aneurysm) 5 5.7
IPVG ( GSV ) 82 23
Re-intervention 1 7.7
Amputation ( n= 8 ) 10 7.7
Mortality 3.6 12.7

Our Strategies

  1. Prefer Posterior approach for popliteal artery injury where P3 is reformed.
  2. Always autologous conduit in Trauma.
  3. Radical debridement.
  4. Soft tissue Cover- Plastic Surgeons involved.
  5. Skeletal stabilization- Upfront unless limb immediately threatened.

Conclusion

  1. Our experience Limb Salvage 90%
  2. Early intervention (Within 24 hr)
  3. Using autologous conduits (100%)
  4. Skeletal stabilization (Upfront) prior to repair.

Areas to introspect

  1. Functional outcome at 6 months and 1 year.
  2. PGs of Vascular, Orthopaedics and Plastic Surgery to jointly collect and contribute to data on Extremity Vascular Trauma prospectively.
  3. Monitor timelines from presentation to imaging to OR.
