“…The normal and complicated aortic graft prosthesis can also be seen. 13 In conclusion, plastic catheters, tubes, and materials used for medical reasons can be recognized in the human body using ultrasonography. The flexible and mobile scanners, low cost, and absence of ionizing radiation make ultrasonography mandatory in evaluating patients in whom such materials are used.…”

The ultrasonographic appearance of different plastic catheters, tubes, and prostheses used in medical practice were tested in vivo and in vitro. According to the direction of the sound beam, the different plastic catheters and tubes appeared as parallel echogenic lines if scanned longitudinally, or as echogenic dots if scanned transversely. The exact position of the tip of the catheter and its relationship to neighboring organs can be established by ultrasonography. Repositioning of tubes, if necessary, can be done under ultrasonographic guidance. The flexibility and mobility of modern ultrasound scanners allows one to examine the sick patient with minimal disturbance, and to evaluate the location and effect of the various plastic catheters and tubes inserted into the body for medical reasons.

Twelve patients with a clinical diagnosis of possible vascular graft infection have been studied over the last 3 years. All patients had their leucocytes labelled with indium-111 and gamma-camera imaging after 24 and 48 h. Subsequent management was according to established surgical techniques. Eight patients proved to have vascular graft infection and indium uptake was seen along the length of the graft in six. Two patients with open wound infections and synthetic grafts had localized uptake only on leucocyte scanning. Four patients, all of whom had negative scans were not thought to have infected grafts after further investigation using digital subtraction angiography and computed tomography scanning. These patients have been followed up for a median period of 19 months (range 5-25 months) and have remained symptom free. Initial experience with 111In-labelled leucocyte scanning has been encouraging, both in diagnosis and in planning the management of patients with graft infections.
