The placement and management of venous access devices has become a routine and large part of the vascular and interventional radiologic practice. Compared with surgical series, our technical success is better and our complication rates are lower. A dedicated team approach with patient follow-up and management is required to create and maintain a successful line service.

Comparative Study
Geographic variation in the number of authors on scientific abstracts.
To determine if there was statistically significant geographic variation in the number of authors on abstracts of the 1999 Radiological Society of North America (RSNA) Scientific Assembly. ⋯ There seems to be significant geographic variation in the number of authors credited on scientific presentations.

Patients with cancer require reliable venous access for therapy and phlebotomy. Traditionally, insertion of venous ports has been performed in the operating room. However, the interventional radiology service has recently become involved in the placement of a variety of venous access devices. This study examines the technique and complications associated with the placement of venous ports in the arm for patients with cancer. ⋯ The Cook titanium Petite Vital-Port, implanted in the arm in the medical imaging vascular/interventional suite, is relatively safe and effective. As a result, it has been widely accepted by the patients and clinicians at the hospital where this study was conducted.

Inferior vena cavae (IVC) can be of unusual geometry, often having odd shapes and being oriented (in long axes) away from the horizontal plane. However, after insertion of a filter, most IVC adopt a circular cross-section. The objective of this study was to determine if the IVC diameter estimated by frontal measurement (cavogram equivalent) reflects the true circular diameter of the infrarenal vena cava. Diameter estimation is clinically important in the correct selection of a filter, because mega cavae (diameter 28 mm or greater) require a particular filter. ⋯ Cavograms can over- or underestimate the true diameter of an IVC, and may thus lead to incorrect filter choice. It is recommended that a sonogram or CT scan be obtained to visualize the IVC in cases of suspected mega cava, and that true circular diameters be used for selection and placement of IVC filters.
