Popis: | Some preventable diagnostic problems and risks related to medical devices indicate the need for logical marker standards and for input from radiologists in the design of these devices. The problems range from undetectable items inserted in the body to external equipment that needlessly hides detail on radiographs. The variety and absolute numbers of such devices used in patient care and monitoring are rapidly increasing. Some voluntary standardsfor radiologic detectability exist, but there is no organized method for the dissemination of these standards. A surprising variety of important devices are invisible or poorly opaque, ensuring lack of detection by radiography. These include venous catheters, vascular grafts, heart valve and breast prostheses, feeding tubes, and even ventricular shunts. Abstract markers for surgical sponges and pads can be mistaken for drains, surgical clips, or wire sutures [1 , 2]. Single wire markers found in tubes, aortic balloons, and venous catheters are similar to transcutaneous nerve stimulators and electrocardiographic leads. Rarely used specialty prostheses can be confusing without a detailed clinical history. All devices intentionally placed in patients or left in accidentally pose risks of infection, breakage, and displacement. Tubes and grafts may obstruct or leak. Casts, braces, and other external equipment can hide underlying anatomy and pathology. Dressings and stopcocks may cause confusing radiographic shadows. The following examples from a large hospital illustrate these problems (figs. 1-8). Discussion |
