Venous thromboembolism after retrieval of inferior vena cava filters.
To determine the incidence of venous thromboembolism (VTE) after removal of retrievable inferior vena cava (IVC) filters. ⋯ VTE was rare after removal of IVC filters, but was most likely to occur in patients who had VTE at the time of filter placement.

Radiofrequency ablation in combination with osteoplasty in the treatment of painful metastatic bone disease.
To evaluate the feasibility and effectiveness of combining radiofrequency (RF) ablation and osteoplasty for pain reduction in the treatment of painful osteolytic metastases. ⋯ RF ablation and osteoplasty can be combined within one session and is both feasible and useful for the treatment of osteolytic bone metastases with regard to pain relief.

Cavoatrial junction and central venous anatomy: implications for central venous access tip position.
To quantify the anatomic relationships of the cavoatrial junction and propose a system for describing central venous access device tip location on the basis of structures visible on chest radiographs. ⋯ A more accurate understanding of the superior vena cava anatomy is essential for the correct interpretation of central venous access device position. The true cavoatrial junction is located more inferiorly than commonly believed and is not accurately estimated with commonly used imaging landmarks. A point two vertebral body units below the carina enables the reliable estimate of the position of the cavoatrial junction. Catheter tip position can be most reliably described in vertebral body units below the carina, with use of the thoracic spine as an internal ruler.

Randomized Controlled TrialHow do patients perceive the benefits and risks of peripheral angioplasty? Implications for informed consent.
To explore perceptions of benefits and risks of patients undergoing peripheral angioplasty and to investigate factors that modify them. ⋯ Patients who undergo peripheral angiography tend to underestimate the risks and overestimate the benefits of peripheral angioplasty. The patient information sheet and risk assessment tool used in this study altered patient perceptions of risks and benefits of the procedure and, therefore, aid informed consent.

Comparative StudyTunneled infusion catheter breakage: frequency and repair kit outcomes.
To determine the frequency of tunneled infusion catheter breakage and the durability of a repair kit used to repair damage to the external catheter segment, avoiding catheter replacement. ⋯ Tunneled infusion catheter breakage is common. Given the high breakage rates observed for many catheter designs, the development of more durable catheters should be a priority for catheter manufacturers. Until more durable catheters are developed, the catheter repair kit studied is an easy, effective, durable, and relatively inexpensive solution for the repair of external segment damage in tunneled infusion catheters.
