Bullet Embolism Management in Vascular Systems
Summary
Bullet embolism is a rare but serious complication of penetrating firearm injuries in which a projectile enters the bloodstream and migrates to distant vascular beds, potentially causing ischaemia, haemodynamic instability or end-organ damage. Management strategies hinge on prompt diagnosis through high-resolution imaging modalities such as contrast-enhanced computed tomography and angiography, combined with a high index of clinical suspicion in cases without an exit wound or when symptomatology diverges from expected trajectories. Therapeutic approaches range from conservative observation for asymptomatic, fixed projectiles to minimally invasive endovascular retrieval using snares or catheters, and conventional open surgery for missiles lodged in critical or inaccessible vessels. Hybrid protocols that integrate endovascular stent grafts, targeted thromboembolectomy and selective arteriotomy have emerged to minimise morbidity while preserving vascular integrity. Multidisciplinary teams comprising trauma surgeons, interventional radiologists and vascular specialists are pivotal to tailor management to anatomical location, projectile size and patient stability, thereby optimising outcomes and reducing the risk of long-term sequelae.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
