Transient thoracic venous collaterals: an incidental CT finding.

Four patients exhibited thoracic venous collateral circulation on CT of the chest. No clinical or CT evidence of venous obstruction was seen. Repeat CT in one patient following repositioning of the arms from hyperabducted to the anatomic position showed absence of collateral circulation. It appears that hyperabduction of the arms during performance of chest CT can occasionally cause transient obstruction of the subclavian vein and opacification of collateral venous channels.

Successive abdominal roentgenograms: a new method of evaluating postoperative small bowel activity.

The technique of two successive abdominal roentgenograms at a five minute interval is proposed as a new method of evaluating small bowel activity in the presence of postoperative intestinal distention. One hundred and forty-four cases of postoperative small bowel distention were studied with this technique and correlated with the clinical evaluation of the bowel sounds and with the development of a variety of postoperative complications. Correlation with the bowel sounds was fairly good, except in the presence of a clinical description of hypoactive sounds. Reduced activity on the successive roentgenograms after the third postoperative day was frequently associated with postoperative complications, while persistent small bowel distention in the presence of significant roentgen activity usually indicated mechanical small bowel obstruction. This method for determination of small bowel activity thus appears to be useful in evaluating postoperative problems.
