Management of Explosion-Related Oesophageal and Proximal Subclavian Artery Injuries
Direct repair of both the oesophageal and proximal subclavian artery injuries (option A) is the treatment of choice for patients with explosion-related neck trauma. 1
Primary Management Approach
The management of combined oesophageal and subclavian artery injuries requires immediate and definitive intervention due to the high risk of mortality and morbidity:
- Direct operative repair of both structures is the recommended first-line treatment whenever feasible, as it provides the best outcomes for patient survival 1
- Mortality of traumatic oesophageal injuries is extremely high, with 92% of deaths occurring within 24 hours, making immediate definitive repair critical 1
- For cervical oesophageal injuries specifically, direct repair of the perforation should be attempted as the primary approach 1, 2
Surgical Technique for Combined Injuries
Oesophageal Repair:
- Two-layer repair with separate suturing of the mucosa and muscle is recommended to minimize suture breakdown risk 1
- Longitudinal myotomy at both ends of the oesophageal perforation helps expose mucosal edges for appropriate repair 1
- Buttressing the oesophageal repair with surrounding viable tissue decreases leakage risk and prevents complications such as tracheo-oesophageal fistula 1, 2
Subclavian Artery Repair:
- Direct repair of the subclavian artery is preferred over ligation whenever possible 1, 3
- Proper surgical exposure is critical - midline sternotomy for right subclavian injuries and anterolateral thoracotomy for proximal left subclavian injuries 3
- Temporary hemostatic control may be achieved with endovascular balloon occlusion as an adjunct to surgical repair in cases of severe hemorrhage 4
When to Consider Alternative Approaches
Alternative approaches (options B, C, or D) should only be considered in specific circumstances:
- Esophagostomy with arterial repair (option B) should only be considered if direct oesophageal repair is not feasible due to large disruption, delayed surgery, or pre-existing oesophageal disease 1
- Subclavian artery ligation (options C or D) is generally avoided due to the high risk of limb ischemia, but may be necessary in extreme circumstances where repair is technically impossible 5
- In hemodynamically unstable patients, damage control principles may be applied with abbreviated source control surgery followed by ICU resuscitation and a second-look procedure 1
Critical Adjunctive Measures
- Adequate drainage around the repair site is essential to prevent complications 1
- Decompression of the oesophagus and stomach via nasogastric tube is recommended 1
- Distal enteral nutrition through a feeding jejunostomy should be considered to support healing 1
- Close monitoring for complications including infection, respiratory compromise, and wound healing issues is required during the postoperative period 1, 2
Prognostic Factors and Complications
- Predictors of poor outcomes include hemodynamic instability on arrival, multiple associated injuries, and gunshot mechanisms 5, 6
- Associated brachial plexus injury accounts for the majority of long-term morbidity in survivors 5
- Complications are more common in patients presenting with initial systolic blood pressure less than 90 mmHg 6
