Introduction
Pelvic Trauma:• Excellent knowledge of the anatomy
• Complex anatomic relation, pathway of nerves and vessels networks
• Substantial force.
• There are many organs in it.
• Connects to abdominal and retroperitoneal space.
• Rapid transportation to a trauma center, early recognition of the injuries.
• Early surgical intervention, good surgical judgment

Surgical anatomy
For vascular trauma purposes: • Zone 1The midline retroperitoneum,from the aortic hiatus to the sacral promontory. The supramesocolic area and The inframesocolic area. • Zone 2 (left and right), Which includes the kidneys, paracolic gutter, and renal vessels.
• Zone 3, Which includes the pelvic retroperitoneum and contains the iliac vessels.

Mechanism of injury
Penetrating trauma :
1. Low-velocity missiles cause direct injury to the vessel. 2. High-velocity missiles and blasts can also cause vascular trauma by
means of the shock wave and transient cavitation.
Blunt trauma (abdomen pelvis):
1. Rapid deceleration, (accidents or falls from heights) 2. Direct anteroposterior crushing, (seat belts) 3. Direct laceration of a major vessel by a bone fragment, as occurs in severe pelvic fractures.

• Rutherford: Arterial injuries (49%) dan venous injuries (51%).• Vascular trauma book(2)
• Arteri common iliaka (40%), a. iliaka internal (30%) a.iliaka eksternal (30%).• Vena: common iliaka (48%), v. iliaka eksternal (32%), v. iliaka internal
(22%)• Blunt trauma : Paling sering vena iliaka internal (strectching atau laserasi)

Clinical Presentation
• Radiologis: pada hemodinamik stabil(2)
• Proyektil
• Blunt trauma: increased risk vascular trauma:
• Presence of symphysis pubis diastisis >2.5 cm
• Sacroiliac joint disruption
• Superior and inferior rami fractures bilaterally (Butterfly fracture)(demetradee et al: undergo angiographic embolization dan massive transfusion)
• CT Scan: (1)
• USG : late abdominal vascular complication
• Angiography: site and severity, control bleeding

• T-bone vehicular crashes
• Fall where lands on side
• Vascular injury may occur
• Generally not substantial blood loss
(concomitant injury)

Management
.
• Prehospital:
• Scoop and run
• Bleeding control
• Fluid resuscitation (controversy, crystalloid fluid)
• Increase rate and volume of blood loss
• Hypotension control
• Hypothermia

Management
.
• Treating Pelvic Hemorrhage:
• Principle: reducing fracture
• Bed sheet:
• Greater trochanter: the compressive device is centered over the greater
trochanters of the hip, not over the iliiac crest
• Crisscrossed
• Mannually reduces the pelvis, post reduction x-ray
• MAST (military anti-shock trouser), PASG (pneumatic anti-shock garments)
• C-Clamp

Management
.
• Treating Pelvic Hemorrhage:
• Angiographic embolization
• Time, place, and personnel required
• A flush pelvic aortogram, then selected pelvic angiography
• Embolization
• Direct operative exploration

Management
.
• Operating management:
• Arterial injuries:
• Compression and control(proximal and distal)
• Iliac vessels: approach : dissection paracolic peritoneum and medial rotation
the colon.
• Proximal control: clamp> vessel tape
• Distal vessel: can be difficult, extending midline incision
• Primary repair
• Ligation the common and external iliaca should be aviod (50% limb loss)

Management
.
• Operating management:
• Venous injuries:
• More challenging: difficult exposure and air embolism
• Lateral venorraphy
• Ligation
• SE: stenosis (possb 50%), edema and compartment syndrome (from ligation)
• Individual choice

Conclusion
.
• Hemodinamically unstable patient with pelvic fracture present a unique challenge.
• Diagnosing the sources and resuscitation
• Close coordination
• Algorithm and tools to manage
