Abstract:
A central venous port catheter inserted infraclavicularily via the subclavian route may be compressed by the clavicle and the adjacent first rib. It's appearance on chest x-ray has been previously described as the 'pinch-off phenomenon' and requires the removal of the catheter due to a significant risk of fracture. We report the case of a catheter fracture without prior evidence of pinch-off. The free catheter fragment was embolized into the right atrium and caused pericardial effusion. Percutaneous removal of the fragment was attempted but failed and thus open heart surgery with a cardiopulmonary bypass was required. The myocardial lesion caused by the catheter was sutured.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
