Endovascular Removal of Pulmonary Artery Bullet Embolus: Case Report and Literature Review.

The current state of the literature for a bullet embolization to the heart and/or pulmonary vasculature indicates the occurrence is rare but could increase due to the rise in civilian low-kinetic-energy firearm acquisition and use. We present the case of an older teenage male who sustained a gunshot wound to the left flank. The bullet entered the iliac vein, travelled through the heart and lodged in the pulmonary artery. Successful relocation of the bullet to the internal iliac vein was performed by the interventional radiologist. This article highlights the advancement of interventional radiology as a successful non-invasive endovascular technique for bullet embolus removal.

The Pearls and Pitfalls of a Migrating Bullet Embolus.

Venous bullet embolism is an exceedingly rare trauma diagnosis that presents diagnostic and therapeutic challenges. We present the case of a 32-year-old man who sustained multiple gunshot wounds with a venous bullet embolism to the right pulmonary artery. Imaging at first demonstrated a bullet lodged within the right lower lobe. The patient underwent multiple bronchoscopies and ultimately was found to have a bullet embolus in the right pulmonary artery. Repeat endovascular attempts failed at removal, and during a right thoracotomy, the bullet migrated to the left pulmonary artery. Coil embolization of the left lower lobe pulmonary artery was performed, and the patient was found to be asymptomatic at the 1-year follow-up. To our knowledge, this is the first case to demonstrate coil embolization of the pulmonary artery as a method of endovascular treatment for a venous bullet embolus. We present this case report to emphasize the difficulty in diagnosis, localization, and management of a migratory bullet within the pulmonary circulation.

Management of Venous and Arterial Bullet Emboli.

Gunshot wounds account for significant morbidity and mortality in the United States. A rare and potentially fatal complication of a gunshot wound is bullet embolus. Potential complications include distal limb ischemia, coronary infarct, renal infarction, stroke, pulmonary embolization, cardiac valvular injury, thrombophlebitis, and dysrhythmias. Overall, surgical embolectomy and endovascular retrieval are the preferred treatments for bullet emboli. We report one case of venous bullet embolus and one case of arterial bullet embolus, both of which were successfully treated with endovascular retrieval. A thorough physical exam and appropriate imaging are vital to prompt identification and treatment of bullet emboli, as the repercussions of missed injuries can be devastating.

Unusual bullet embolism in the brachial artery: Case report and literature review.

Chest cardio-vascular trauma by a gunshot bullet is less common than head trauma in forensic medicine practice, but still an extremely mortal injury. In front of no exit wound, ballistic trajectory could appear unexplained. We present the case of a 43-year-old man who sustained a gunshot wound in his chest. The entrance was facing the sternum and there was no exit wound. An autopsy completed by forensic radiology (CT-scan of the whole body) showed a wound of anterior pericardial, massive bleeding of pericardia, a wound of the anterior ascending thoracic aorta, and then the bullet embolism to the left brachial artery. Without forensic imaging, the bullet was difficult to find. Bullet embolization should be suspected when there is a gunshot injury to the chest without an exit injury and with no projectile in the area, particularly if the projectile is small. Forensic radiology can help to find bullet projectile: by using whole-body radiography or computed tomography.

Videothoracoscopic approach to the extraction of a cardiac retainer missile.

The presence of foreign bodies (FB) retained in the heart or pericardium secondary to penetrating trauma in stable patients is a very rare event and its management is controversial. We present the case of a 19-year-old patient who was admitted to our trauma center hemodynamically stable because of two gunshot wounds in the lumbar region. A chest x-ray (CXR) revealed a blurred foreign body over the right heart chamber, thoracoabdominal computed tomography (CT) scan showed a free projectile over the left atrial wall, and transesophageal echocardiogram (TEE) showed a hyperrefringent pericardial sac image near the right ventricle. Finally, the patient went to surgery where a missile was removed from the pericardial sac by video-assisted thoracoscopic surgery (VATS).

Left pulmonary artery bullet embolism following a penetrating cardiac gunshot injury.

INTRODUCTION: Bullet emboli occur when bullets migrate from an entry point to an abnormal endpoint via blood vessels or bowel. Most result from low-velocity, small calibre civilian gunshots. Although rare, when it does occur, it commonly embolises to the arterial system. Many times, these are amenable to removal and recovery. CASE REPORT: We present a case of a haemodynamically unstable polytrauma patient with a pulmonary artery projectile embolus following a penetrating trans-thoracic cardiac gunshot wound. CONCLUSION: A brief overview of the literature regarding bullet emboli is provided in light of this unusual case, focusing specifically on thoracic bullet emboli. A high index of suspicion should be raised when the number of entry and exit wounds are incongruent, bullet location does not align with anticipated trajectory, or serial radiographs demonstrate missile migration. Radiological evaluation and bullet retrieval are dependent on haemodynamic stability of the patient.

A Case Series of Anterograde and Retrograde Vascular Projectile Embolization.

Deaths related to firearms are common within the United States, with most cases having conspicuous projectile wounds found at autopsy. Individual gunshot wounds may be perforating or penetrating. In most cases with penetrating wounds, projectiles are relatively easily found via radiography and by following the pathway on internal examination. When a projectile is not detected in the expected region, intravascular embolization of the projectile should be suspected. Embolization may be arterial or venous, as well as anterograde or retrograde. Typically, such emboli involve small caliber bullets or shot pellets. The authors present three unusual cases of intravascular projectile embolization at autopsy, one involving shotgun slug fragment embolization, one where death was delayed, and one with retrograde embolization into the liver.

I Want My Bullet Back: Percutaneous Endovascular Removal of a Right Atrial Foreign Body.

The incidence and prevalence of firearm-related homicide in the United States make headlines daily. As a result, an epidemic of penetrating injuries is on the rise. Specifically, foreign bodies such as bullets and shrapnel are usually left inside the human body due to penetrating injuries, unless they are in close proximity to vital structures. We present a case of a bullet within the right atrial chamber of the heart, which was successfully removed by a minimally invasive endovascular approach.

Gunshot Pellet Migration to the Right Ventricle: a Case Report and Literature Review.

The diagnosis and management of injuries of the heart or the great vessels continues to be a major surgical challenge in the past and now. This case study introduces the conservative management of a patient who developed a venous bullet embolus after being shot in the lower extremities. In this case report, we aim to review some of the literature on bullet emboli and to raise awareness of its existence. It was concluded that for bullets left in the limbs, bullet position in relation with peripheral vessels should be evaluated carefully to treat and avoid the bullets moving along with the bloodstream.

The anesthetic management of a venous bullet embolism to the right ventricle: A case report.

Bullet embolism is a rare complication of non-penetrating gunshot trauma. There are two types of bullet embolisms: arterial and venous. Accurate preoperative localization of the bullet is important for selecting the proper surgical and anesthetic techniques. We report here on a rare case of venous bullet embolus to the right ventricle from the right iliac vein, as was demonstrated by transesophageal echocardiography.
