  1. UC UC SF SF Vascular Trauma @ SFGH: Practical Lessons Learned Shant M. Vartanian, MD Assistant Professor of Surgery Division of Vascular and Endovascular Surgery Priscilla and Mark Zuckerberg San Francisco General Hospital and Trauma Center VASCULAR SURGERY • UC SAN FRANCISCO VASCULAR SURGERY • UC SAN FRANCISCO UC UC SF SF Disclosures: Vascular Trauma • None • Blunt aortic injury • Balloon occlusion • Cerebrovascular trauma • Pelvic vascular injuries • Iatrogenic Trauma • Blunt vs. Penetrating injuries • Endovascular treatments • Combined orthopedic and vascular injuries of the limbs VASCULAR SURGERY • UC SAN FRANCISCO VASCULAR SURGERY • UC SAN FRANCISCO 1

  2. UC UC SF SF Patterns of Orthopedic Vascular Combined Skeletal and Vascular Trauma Injuries • Not just limited to the battlefield! • Clavicle fracture subclavian artery • Proliferation of motor vehicles • Shoulder dislocation axillary artery • Distracted pedestrian safety • Supracondylar humerus fx brachial artery • Urban violence and terrorism • Elbow dislocation brachial artery • Fall from standing in the elderly • Pelvic fracture gluteal arteries • Sports injuries • iliac arteries • Femoral shaft fx femoral artery • ~3% of long bone fractures are associated with arterial • Distal femur fracture AK popliteal artery injury • Knee dislocation BK popliteal artery • Blunt trauma predominant mechanism in civilian series • Tibial shaft fx tibial arteries VASCULAR SURGERY • UC SAN FRANCISCO VASCULAR SURGERY • UC SAN FRANCISCO UC UC SF SF Patterns of Orthopedic Vascular Patterns of Orthopedic Vascular Injuries Injuries • Distal femur fracture Above knee popliteal artery • Clavicle fracture Subclavian artery VASCULAR SURGERY • UC SAN FRANCISCO VASCULAR SURGERY • UC SAN FRANCISCO 2

UC UC SF SF Patterns of Orthopedic Vascular Patterns of Orthopedic Vascular Injuries Injuries • Femoral shaft fx SFA • Supracondylar humerus fx brachial artery • Tibial shaft fx tibial arteries • Elbow dislocation brachial artery VASCULAR SURGERY • UC SAN FRANCISCO VASCULAR SURGERY • UC SAN FRANCISCO UC UC SF SF Patterns of Orthopedic Vascular Patterns of Orthopedic Vascular Injuries Injuries • Types of injury • Knee dislocation popliteal artery - Spasm - Intimal flaps - Subintimal hematoma - Laceration - Transection - Thrombosis/Occlusion - A-V fistula Some require treatment, some do not • VASCULAR SURGERY • UC SAN FRANCISCO VASCULAR SURGERY • UC SAN FRANCISCO 3

UC UC SF SF Case Presentation Case Presentation • CT Head/Chest/Abd/Pelvic • Discharged to rehab day #28 neurologically intact and full function of his right hand • Pelvic ex-fix - Multiple pelvic injuries • Humerus repair - Transverse process spine fractures - Kidney and liver laceration • Interposition saphenous vein to repair brachial artery - Sternal fracture • Thrombectomy of radial artery - Bilateral rib fractures, clavicle fracture - Pulmonary contusions • Transposition of radial artery into brachial artery graft - Bilateral subdural hematoma • Forearm fasciotomy - PE VASCULAR SURGERY • UC SAN FRANCISCO VASCULAR SURGERY • UC SAN FRANCISCO UC UC SF SF Complex Extremity Trauma Initial Management • Resuscitation and management of all life-threatening • Lack of Class I evidence guiding management injuries takes priority over extremity problems - Rational approach Life over limb - - Best available evidence - Expert consensus opinion • Control of active extremity hemorrhage - Direct pressure • American College of Surgeons Committee on Trauma - Tourniquet • Eastern Association for the Surgery of Trauma (EAST) - Direct clamping of visible vessels practice guidelines - Blind clamping in wounds is discouraged and potentially harmful VASCULAR SURGERY • UC SAN FRANCISCO VASCULAR SURGERY • UC SAN FRANCISCO 7

  8. UC UC SF SF Hard Signs of Vascular Injury Hard Signs of Vascular Injury Up to 75% of hard signs are not due to vascular injury • Active hemorrhage • - Soft tissue or bone bleeding • Large, expanding or pulsatile hematoma - Traction of intact arteries with pulse loss • Bruit or thrill over the wound - Skeletal deformity with pulse loss that corrects with traction Distal Ischemia (the 5 P ’ s) • Absent distal pulses - Compartment syndrome • • Hard signs mandates ruling out vascular injury Applebaum R, Yellin AE, Weaver FA, et al.

VASCULAR SURGERY • UC SAN FRANCISCO UC UC SF SF Imaging Asymptomatic Arterial Injuries Absence of hard signs in an injured extremity excludes a • • Imaging with hard signs can avoid unnecessary limb surgically significant vascular injury as reliably as any exploration in up to 70% of cases imaging modality • Most patients with hard signs are going to the OR - Non occlusive vascular injuries with a benign history may occur - Vascular C arm table vs hybrid room - Ipsilateral micropuncture sheath w/ side arm - Non-selective subtraction angiogram • Soft signs of vascular injury - Contralateral femoral puncture w/ selective subtraction angiogram - Neurologic deficit - Proximity of injury to vessels • Depending on the clinical situation, CTA and DUS have - Significant hemorrhage by history been used for evaluating peripheral vascular injuries with high sensitivity and specificity Frykberg ER, Dennis JW, Bishop K, et al.
