Abstract
Objective: To present the possible toxic effects of lead in victims of traumatic brain injury due to Fire Weapon Projectors (FWP) and its main clinical manifestations, aiming at an early and effective intervention. Bibliographic review: Lead poisoning is a late complication of trauma by PAF, resulting from the cavitation process. Also known as saturnism, it consists of the accumulation of this metal in an organism, the main risk factor being the contact of the projectile with the Cerebrospinal Fluid (CSF), which has an acidic pH responsible for solubilizing lead, which enters the bloodstream and causes damage to organs target, such as neurodegeneration at the brain level. The main form of treatment is the surgical removal of the projectile fragments, however it is important to pay attention to the quantity, distribution and affected areas, before performing the procedure. Final considerations: Among the complications of cranial injuries caused by PAF, lead poisoning is one of the least considered diagnoses, however no less important. This condition can evolve with neurological and systemic damage that compromise the health of patients, with early diagnosis and intervention being of great importance to prevent worsening.
