Surgical Approaches for Abdominal Wall Hematoma Evacuation

Assessment and Initial Management

Evaluate hemodynamic stability first, as large abdominal wall hematomas can cause substantial hemorrhage requiring fluid resuscitation, according to Praxis Medical Insights 1
Consider reversal of anticoagulation before surgical intervention, weighing risks and benefits, for patients on anticoagulant/antiplatelet therapy, as recommended by Praxis Medical Insights 1

Percutaneous mechanical thrombectomy is effective for evacuating persistent post-surgical hematomas in a single setting with minimal tissue trauma, with benefits including reduced operative time and reduced tissue trauma, as reported in Stroke 2
The reduced surgical exposure in minimally invasive approaches may limit the ability to treat structural lesions or identify all bleeding sources, as noted in Stroke 2
Prolonged indwelling catheters in minimally invasive approaches may increase infection risk, according to Stroke 2

Damage control principles should be applied in severely injured patients with hemorrhagic shock, signs of ongoing bleeding, coagulopathy, or hypothermia, as recommended in Critical Care 3
When definitive fascial closure cannot be achieved after hematoma evacuation, consider skin-only closure with delayed abdominal wall reconstruction, as suggested in World Journal of Emergency Surgery 4

For large defects following evacuation, consider component separation technique for reconstruction of abdominal wall defects, as recommended in World Journal of Emergency Surgery 4
In cases with exceptionally large defects, microvascular tensor fasciae latae flap may be a feasible option, according to World Journal of Emergency Surgery 4
