Imaging

Those who care for patients with pulmonary, critical care or sleep disorders rely heavily on chest radiology and pathology to determine diagnoses. The Southwest Journal of Pulmonary, Critical Care & Sleep publishes case-based articles with characteristic chest imaging and related pathology.

The editor of this section will oversee and coordinate the publication of a core of the most important chest imaging topics. In doing so, they encourage the submission of unsolicited manuscripts. It cannot be overemphasized that both radiologic and pathologic images must be of excellent quality. As a rule, 600 DPI is sufficient for radiographic and pathologic images. Taking pictures of plain chest radiographs and CT scans with a digital camera is strongly discouraged. The figures should be cited in the text and numbered consecutively. The stain used for pathology specimens and magnification should be mentioned in the figure legend.

Medical Image of the Week: Migration of Fractured PICC Line

Figure 1. Chest radiograph showing catheter fragment coiled within the main pulmonary artery with the tips extending to the peripheral pulmonary vasculature (arrow).

A 29 year old man had a peripherally inserted central catheter (PICC, 60 cm, 4 Fr, single lumen Groshong), placed at a rural hospital via right brachial vein approach for long term antibiotic therapy for an infected diabetic foot. Two days later, nursing staff noticed difficulty in flushing the PICC line. A chest X-ray was obtained which showed fracture of a portion of the PICC line with migration to the pulmonary vasculature (Figure 1). The broken catheter was successfully removed in a two-step process using a 6 x10 mm EN Snare® from the left pulmonary artery. The patient, however remained asymptomatic and without any arrhythmias on the telemonitor. Intravascular migration and subsequent malposition of PICC lines are usually due to their pinch off, small size, as well as changes in intrathoracic pressure and body position (1).
