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: Medical Administrative Growth

Figure 1. Growth of administrators compared to physicians 1970-2010 (used with permission of David Himmelstein).

It is generally agreed that healthcare costs are too high in the US. Although there has been considerable finger pointing, there is little doubt that administrative costs are far outpacing other healthcare costs. In ground-breaking work published in 1991, Woolhandler and Himmelstein (1) found that US administrative health care costs increased 37% between 1983 and 1987. They estimated these costs accounted for nearly a quarter of all health care expenditures. They followed their 83-87 report by examining data from 1999 (2). US administrative costs had risen to 31% of US health care expenditures. Himmelstein now estimates that administrative costs may now account for up to 40% of healthcare costs (Robbins RA, personal communication). The trend is perhaps best illustrated by Figure 1 showing growth of administrators compared to physicians from 1970-2010 (3).

Medical Image of the Week: Malposition of Central Venous Catheter

Figure 1. Portable anterior-posterior chest x-ray showing the tip of the catheter projecting on the left lung filed instead of crossing the midline.

 

Figure 2. Coronal images of computed tomography of head, neck, and upper chest. Yellow arrows showing the anatomical course of the left internal jugular catheter. Left upper image showing the catheter entering the internal jugular vein. Right lower image showing the tip of the catheter in the left inferior pulmonary vein.

 

A 66-year-old man a with history of systolic heart failure and end-stage renal disease on hemodialysis was admitted to the intensive care unit due to cardiogenic shock requiring inotropes. As left arm fistula was clotted, left internal jugular vein triple-lumen catheter (IJC) was placed to obtain a hemodialysis access. Central line placement was performed under ultrasound guidance with no complications. A confirmatory chest x-ray revealed central venous catheter malposition; the catheter tip did not cross the midline; instead, it projected over the left lung field which was concerning for arterial puncture of the carotid artery (Figure 1). Bedside ultrasonography showed an appropriate catheter placement in the left internal jugular vein, but the final catheter tip location was unclear. The transduced pressure was low; approximately 5mmHg. A blood gas sample from the catheter was compatible with arterial blood; pH 7.42, pCO2 34, and pO2 92. Computed tomography scan of the head and neck showed the IJC entering the left jugular vein, coursing within an anomalous left pulmonary vein, and terminating within the left inferior pulmonary vein (Figure 2). The catheter was not used and was withdrawn without complications.

One of the notable complications of central venous catheter (CVC) placement is malposition, with an approximate rate of 6,7 % (1). Catheter malposition indicates that the catheter tip lies outside the recommended position (within the mid lower part of the superior vein cava (SVC) above its junction with the right atrium and parallel to the vessel walls). Possible sites of central catheter malposition include the carotid artery, azygos vein, persistent left‑sided SVC, internal mammary vein, vertebral vein, pericardium, pleural space, thoracic duct and mediastinum (2). As artery puncture in the carotid artery can lead to serious complications, malposition of the catheter should be addressed in a stepwise approach. Initially bedside ultrasound should be performed to determine the anatomical catheter course and the position of the tip. A pressure transducer is also helpful in differentiating venous versus arterial waveform and measuring the transduced pressure, obtaining arterial blood gases and eventually confirming the catheter position with CT scan or CT angiography. Malposition of the jugular catheterization incidentally revealing partial anomalous of pulmonary venous return was described in a very few cases in literature, the catheter was used for seven days for continuous veno-venous hemofiltration in one of these cases (3). At this time there is insufficient literature to determine the safety of using CVC inserted in an anomalous pulmonary vein.
