As endovascular therapies increase in frequency, the incidence of lost or embolized foreign bodies is increasing. The presence of an intravascular foreign body (IFB) is well recognized to have the potential to cause serious complications. IFB can embolize and impact critical sites such as the heart, with subsequent significant morbidity or mortality. Intravascular foreign bodies most commonly result from embolized central line fragments, but they can originate from many sources, both iatrogenic and noniatrogenic. The percutaneous approach in removing an IFB is widely perceived as the best way to retrieve endovascular foreign bodies. This minimally invasive approach has a high success rate with a low associated morbidity, and it avoids the complications related to open surgical approaches. We examined the characteristics, causes, and incidence of endovascular embolizations and reviewed the various described techniques that have been used to facilitate subsequent explantation of such materials.

Foreign bodies are occasionally reported in the bladder. In most cases, the foreign body is removed via the transurethral approach. A 57-year-old male patient was referred to our hospital to undergo t...
Intrapleural foreign body is an uncommon condition, usually encountered in the setting of thoracic trauma, but can rarely complicate diagnostic procedures such as thoracentesis. The management involve...
In many cases, the presence of periocular foreign bodies continues to be a diagnostic challenge and a dilemma regarding their management in most cases. The key lies in the type of material of the fore...
Deep bronchial obstruction in children caused by foreign bodies is a medical emergency frequently accompanied by the formation of granulation tissue in the airway mucosa, which is resected during remo...
Task forces of the European Respiratory Society (ERS, 2003) and the American Thoracic Society (ATS, 2015) both recommend rigid bronchoscopy for foreign body removal in children. However, there is an i...
The purpose of this study is to determine whether a bedside portable endoscopy is effective in identifying the esophageal foreign body in the emergency room.
In this study the investigators are examining the effectiveness of two different speech therapy protocols for word retrieval impairments experienced by individuals with stroke-induced apha...
This study is designed to evaluate the technical performance and clinical handling of a coronary catheter that includes two imaging techniques. The catheter being evaluated performs near ...
To diagnose hepatocellular carcinoma (HCC) and to determine the extent of the disease, a triphasic CT scan or a magnetic resonance imaging are required. The characterization of hepatic nod...
This is an experimental study in which the efficacy of three psychophysiological intervention modalities based on retrieval-extinction procedures is analyzed.
Histiocytic, inflammatory response to a foreign body. It consists of modified macrophages with multinucleated giant cells, in this case foreign-body giant cells (GIANT CELLS, FOREIGN-BODY), usually surrounded by lymphocytes.
Chronic inflammation and granuloma formation around irritating foreign bodies.
Migration of a foreign body from its original location to some other location in the body.
Treatment methods or techniques which are based on the knowledge of mind and body interactions. These techniques can be used to reduce the feeling of tension and effect of stress, and to enhance the physiological and psychological well-being of an individual.
Multinucleated cells (fused macrophages), characteristic of granulomatous inflammation, which form around exogenous material in the skin. They are similar in appearance to Langhans giant cells (GIANT CELLS, LANGHANS), but foreign-body giant cells have more abundant chromatin and their nuclei are scattered in an irregular pattern in the cytoplasm.
