Nonthrombotic Pulmonary Embolism From Inorganic Particulate Matter and Foreign Bodies

Surgical Management of a Bullet Embolism to the Pulmonary Artery

“…Typical entry sites of the GSW are proximal lower extremity, buttock, back, abdomen, and neck [6]. Entrance to the vasculature may be through venous or arterial access [8]. The mechanisms causing tissue damage are through laceration, crush, shock wave, and cavitation injuries [9].…”

“…Once the bullet enters the vasculature migration generally occurs in the direction of blood flow until the fragment is obstructed or becomes lodged in the pulmonary arterial tree as in the case [10]. At this juncture, pulmonary and systemic consequences may be in the form of mechanical obstruction, causing ischemia, or due to the nature of the material and contamination, which may be a nidus for infection [6,8,11].…”

A Rare Case of Pulmonary Embolism Due to Endovascular Coil Embolization and Review of Literature

“…The pattern presented in chest CT will depend on the type of embolization. Disperse radiopaque/metallic small densities, centrilobular ground glass opacities, and micronodules/miliary nodules, as well as fibrotic/ consolidative opacities, may indicate NTPE [1].…”

“…On physical examination, the temperature was 37.0 °C, the blood pressure 125/80 mm Hg, the pulse 90 beats per minute, the respiratory rate 12 breaths per minute, and oxygen saturation 95% while the patient was breathing room air. Both lungs were clear, and the Introduction Nonthrombotic pulmonary embolism (NTPE) is a partial or complete occlusion of the pulmonary vasculature by organic or inorganic materials [1]. The most frequent causes associated include cancer, infective agents, fat, amniotic fluid, gases and foreign materials.…”

Nonthrombotic Pulmonary Embolism by Foreign Body.

“…Non-cruoric pulmonary embolisms are exceptional, their incidence is estimated at 5% of all pulmonary embolisms, they can be septic, gaseous, fatty, metastatic, amniotic, or foreign body (1). The implantable catheter chamber (ICC) plays an important role in the therapeutic management of cancer patients, providing them a long-term venous access.…”
