Comparative StudyComplication rate of venous access procedures performed by a radiology practitioner assistant compared with interventional radiology physicians and supervised trainees.
To compare venous access complication rates associated with procedures performed by radiology practitioner assistants (RPAs) versus interventional radiology (IR) faculty members, IR fellows, and radiology residents. ⋯ A properly trained and monitored RPA can safely perform selected venous access procedures with complication rates equal to those of IR faculty members, fellows, and residents.

Assessment of metastatic breast cancer response to chemoembolization with contrast agent enhanced and diffusion-weighted MR imaging.
To assess the value of functional magnetic resonance (MR) imaging in the evaluation of early tumor response after transarterial chemoembolization (TACE) for metastatic breast cancer and to compare tumor response based on functional MR imaging versus traditional assessment based on iodized oil deposition, tumor size, and tumor enhancement. ⋯ In patients with breast cancer and liver metastases who were treated with TACE, although changes in tumor size were small, significant early changes in the treated lesions occurred on contrast medium-enhanced and functional MR imaging. These include decrease in tumor enhancement and increase in tumor ADC value, which suggest increasing tumor necrosis and cell death.

Case ReportsArterial embolization of vaginal arterial branches for severe postpartum hemorrhage despite hysterectomy.
Postpartum hemorrhage remains a substantial cause of maternal morbidity and mortality. Arterial embolization has been described as a successful primary modality and an important adjunct in the treatment of postpartum hemorrhage. ⋯ The bleeding was controlled with embolotherapy. The findings emphasize the role of angiographic embolization in postpartum hemorrhage.

Radiologically placed tunneled internal jugular catheters in the management of chronic hemodialysis and long-term infusion therapies in the pediatric population.
To evaluate the long-term outcomes of radiologically inserted dual-lumen hemodialysis and infusion catheters in pediatric patients. ⋯ Radiologically placed tunneled internal jugular catheters appear to be safe and effective, with very low complication rates for both hemodialysis and long-term infusion therapies. Higher infection rates were seen in patients with cancer.
