Outline the incidence and clinical picture of patients with lost or embolized foreign bodies. Discuss the causes of lost or embolized foreign bodies. Demonstrate the imaging findings of foreign bodies. Illustrate different interventional techniques for foreign body retrieval. Demonstrate tips and tricks for foreign body removal in difficult situations. Describe the outcomes of removal of foreign bodies using interventional techniques. Outline potential complications.
Lost intravascular foreign body (IFB) is expected in the endovascular therapies.
Common forms of IFB include catheter fragment,
guidewires and device embolization.
Retrieving retained foreign body is crucial to avoid potential adverse events.
Several minimally invasive techniques are effective in removing IFB which is usually preferable to open surgery management.
Understanding the causes,
clinical presentations and imaging findings of lost or embolized IFB facilitates management and assists...
Findings and procedure details
Clinical Picture: The majority of cases are asymptomatic.
Few case series and case reports reported associated symptoms ranging between 5.6% - 32%.
These may include limb swelling,
chest pain from pulmonary embolism,
dyspneaor cardiac arrhythmias. Imaging Obtaining proper history including the size,
shape and suspected location of the lost IFB is important before imaging in order to select the appropriate imaging modality and body part to be imaged.
Plain radiographs are...
Primary prevention is preferable to secondary successful retrieval of a lost IFB.
Retrieval of IFBs can be challenging depending on their type and location. The minimally invasive endovascular approach has repeatedly been demonstrated to have a high success rate with a low associated morbidity,
and spares the complications related to open surgical approaches.
Detailed techniques are important to improve the endovascular management.
Once it is retrieved,
the specimen should be sent for...
