Head/Neck and Thoracic Vascular Trauma Including Blunt Thoracic Aortic Injury

63.1Definition and presentation

Head, neck, and thoracic vascular trauma encompasses blunt thoracic aortic injury (BTAI), blunt cerebrovascular injury (BCVI), penetrating neck vascular trauma, and subclavian artery injuries. BTAI is a deceleration injury classically concentrated at the thoracic aortic isthmus, carrying a high risk of progression or rupture Lee et al. (2011) · Demetriades 2009 · BTAI Concepts 2020. Penetrating neck trauma spans three anatomic zones: zone I extends to the thoracic inlet, zone II occupies the mid-neck, and zone III reaches the skull base Joint Trauma System 2017 · BCVI 2021. Clinical presentation ranges from incidental findings in stable polytrauma patients to life-threatening hemorrhage or tamponade requiring immediate procedural control WSES 2025.

63.2Initial assessment and diagnosis

Initial thoracic assessment uses bedside E-FAST, including a cardiac ultrasound view, and chest radiography when these can be obtained without delaying urgent treatment. FAST is an ultrasound examination, not a surgical pericardial window; normal screening studies do not exclude aortic injury WSES 2025. CTA is the first-line vascular study in patients stable enough for imaging, defining thoracic injury and treatment anatomy. Suspected cervical vascular injury also warrants CTA unless immediate hemorrhage control takes priority. Equivocal cervical CTA, metal artifact or persistent high suspicion despite a negative study may require catheter angiography AAST 2026. High-energy thoracic spine fractures share the deceleration mechanism of BTAI and prompt dedicated aortic CTA Thoracic Spine 2021.

BCVI screening uses modified Denver and Memphis criteria:

• Mechanism of injury
• Cervical spine fracture
• Basilar skull fracture
• Severe facial fracture
• Neurological signs
• Horner syndrome Joint Trauma System 2017 · BCVI Overscreen 2023

63.3Medical management and impulse control

Prehospital resuscitation incorporates balanced blood products, and prehospital plasma improves 30-day survival in patients at risk for hemorrhagic shock Sperry et al. (2018). Impulse control is the primary temporizing medical therapy for BTAI between diagnosis and definitive repair. Short-acting antihypertensives or beta-blockers reduce aortic wall stress, targeting a heart rate of 60 to 80 beats per minute Cochrane 2019 · Lee et al. (2011) · TEVAR Effectiveness 2023 · BTAI Concepts 2020. Anti-impulse treatment must not compromise organ perfusion. In grade 1–2 BTAI with traumatic brain injury, the 2026 SVS guidance prioritizes brain-injury blood-pressure management rather than anti-impulse therapy SVS 2026. For confirmed BCVI, start antithrombotic therapy when associated bleeding permits. Selected asymptomatic occlusions also receive medical treatment; agent and timing require multidisciplinary coordination AAST 2026 · EAST 2020.

63.4Treatment selection and thresholds

Operative or endovascular intervention depends on hemodynamic stability, the anatomic zone, and the specific injury grade. Hospital setting and institutional endovascular volume influence outcomes after TEVAR for blunt thoracic aortic injury, favoring management at, or transfer to, higher-volume centers Cabot 2025. Penetrating and zone-specific cervical injuries are managed selectively based on CTA findings rather than mandatory zone-based exploration Joint Trauma System 2017 · BCVI 2021. Emergency thoracotomy is reserved for penetrating thoracic trauma with signs of life within minutes of arrival or in the trauma bay WSES 2025 · Lee et al. (2011).

Decision workflow for blunt thoracic aortic injury:

1. Determine whether instability is aortic in origin.
2. Grade with the SVS system.
3. Apply the table’s management and surveillance pathway.
4. Assess repair anatomy and competing injuries SVS 2026.

63.5Anatomic interfaces and operative execution

Left subclavian artery coverage during TEVAR is frequently necessary to obtain an adequate proximal landing zone at the arch-isthmus interface. Selective revascularization is performed when dictated by arm ischemia or vertebrobasilar perfusion risks Lee et al. (2011) · BTAI 2023. Spinal cord ischemia and paraplegia rates are lower after TEVAR than after historical open repair, with the residual risk determined by coverage length, periprocedural blood pressure, and collateral circulation TEVAR Effectiveness 2023.

Penetrating vertebral artery transection in cervical spine trauma presents with rapid hemorrhage; management involves direct pressure, packing, or balloon tamponade, alongside rapid transition to endovascular or operative control Tannoury 2015. In blunt vertebral artery injury with unstable cervical spine trauma, surgical spine fixation mitigates ongoing arterial injury from unstable bony elements, requiring careful coordination with the antithrombotic regimen Vertebral Artery 2020. Transcarotid artery revascularization (TCAR) provides a feasible endovascular bailout for focal blunt carotid injuries in select patients, though outcome data remain limited TCAR 2023.

Cervical arteries, thoracic-inlet vessels and veins

In a bleeding penetrating neck wound, protect the threatened airway while maintaining direct hemorrhage control and arranging immediate operative exposure; these are coordinated tasks rather than an instruction to stop compression until intubation is complete. For a repairable common or internal carotid injury, restore continuity by direct repair, patch or interposition according to the defect; a temporary shunt can preserve cerebral perfusion during damage control CPG 2025.

Most blunt vertebral injuries, including selected asymptomatic occlusions, can receive antithrombotic treatment; free arterial bleeding requires source control. Selected jugular injuries without active bleeding may be observed AAST 2026. When an injured internal jugular vein cannot be repaired, ligation requires a patent contralateral internal jugular vein ESVS 2025.

At the subclavian/thoracic-inlet interface, distinguish minor observed injury from a lesion requiring reconstruction. Open or hybrid control is required when bleeding cannot await endovascular treatment; a covered stent is a selected repair option, not a consequence of absent extravasation alone CPG 2025.

63.6Surveillance and long-term follow-up

Post-TEVAR follow-up mandates serial CTA at defined intervals to monitor for endoleak, device migration, and post-implant aortic dilatation Lee et al. (2011) · BTAI TEVAR 2022. Surveillance intervals taper in stable patients, and long-term outcomes show preserved health-related quality of life with low rates of late device-related reintervention TEVAR Effectiveness 2023.

Nonoperatively managed BTAI follows the grade-specific imaging schedule above SVS 2026. Low-grade BCVI and vertebral artery injuries are evaluated with interval imaging over days to weeks; because low-grade injuries often stabilize or improve angiographically, this imaging guides the duration of antithrombotic therapy and confirms lesion stability BCVI 2021 · VAI 2025.

63.7Areas of controversy

The optimal timing of TEVAR for stable grade 3 BTAI relies on evolving evidence rather than established trials. Delayed-repair pathways are widely used to permit concurrent injury stabilization, but randomized comparative data defining the safest delay interval do not yet exist Lee et al. (2011) · Demetriades 2009 · BTAI Concepts 2020.

Screening thresholds for blunt cerebrovascular injury also remain unsettled. Broad application of the modified Denver criteria in low-mechanism trauma populations produces low-yield overscreening, driving ongoing efforts to calibrate threshold triggers to balance stroke prevention against the required imaging burden Joint Trauma System 2017 · BCVI Overscreen 2023.
