Case ReportSurgical management of late bullet embolization from the abdomen to the right ventricle: Case report

- We present the case of a late bullet migration.
- We describe our surgical approach for a bullet extraction.
- We review the literature on the different treatment options in patients with bullet migration.

IntroductionSecondary embolus from gun projectile is a rare entity, it represents a clinical and therapeutic dilemma because the potential complications involving central and peripheral circulation. Each case reported in the literature represents a challenge because their unique and different clinical scenarios.Presentation of caseWe present the management of a 33-year-old man with past history of a gunshot wound on left flank with no evidence of any exit wounds, treated with exploratory laparotomy without removing the gunshot bullet from the abdomen. The patient presents 6 years later with non-productive cough and retrosternal pain with no other symptoms; the patient underwent a chest x-ray, electrocardiogram, thoracoabdominal CT, echocardiogram and cardiac catheterization and showed a bullet in the right ventricular floor. The projectile was extracted by sternotomy with extracorporeal circulation through the right atrium, without any complications.DiscussionIn 1834, Thomas David reported for the first time a wood-fragment embolization. There have been reported less than 200 cases including embolization of other materials; most of the gunshot bullet embolization cases reported on literature were reported after war. Clinical manifestations are associated with the anatomical site of embolism and mortality rate for a retained bullet is 6% associated with complication in 25% of cases. Mortality rate decreases to 1-2% if the bullet is removed.ConclusionThere are no established guidelines about the management of migrating foreign bodies or bullets, however, conservative, endovascular and surgical management have been proposed. In the cases of bullet embolization to the thoracic cavity, surgery represents a safe, low risk approach with high success rates.
