In recent years, there has been a great increase in the number of cases of image-guided fiducial marker placement for the purposes of stereotactic radiosurgery. At the authors' parent institution, a tertiary referral academic medical center, the placement of fiducial markers has also been used for the purposes of localization before spine surgery. Given the reported prevalence of "wrong-site" surgical intervention documented in the medical literature, particularly involving spinal surgery, the neurosurgical department at the authors' institution has requested the expertise of interventional radiology for assistance in preoperative spine localization. Therefore, there are medicolegal, medical cost, and patient care implications of image-guided fiducial marker placement.

Endovascular treatment of penetrating traumatic injuries of the extracranial carotid artery.
To describe the clinical and angiographic results of endovascular therapy for traumatic injuries of the extracranial carotid artery. ⋯ In this series, endovascular techniques were an effective method of treatment. It was possible to use different endovascular reconstructive techniques or parent artery occlusion depending on the degree of vessel damage, with resolution of clinical symptoms and avoidance of surgery in most cases.

Removal of retrievable inferior vena cava filters with computed tomography findings indicating tenting or penetration of the inferior vena cava wall.
To examine the feasibility and safety of removing retrievable inferior vena cava (IVC) filters with struts external to the IVC wall on computed tomography (CT) imaging. ⋯ The appearance of filter struts tenting or penetrating the IVC wall is a common finding on CT performed before filter retrieval. IVC filters with these findings can be removed safely and should not be a contraindication for IVC filter retrieval.

Improving inferior vena cava filter retrieval rates: impact of a dedicated inferior vena cava filter clinic.
To test the hypothesis that an inferior vena cava (IVC) filter clinic increases the retrieval rate of optional IVC filters. ⋯ The retrieval rate of optional IVC filters at this institution was significantly increased by the establishment of a dedicated IVC filter clinic. This retrieval increase is not related to a decrease in technical failures but more likely relates to more meticulous patient management and clinical follow-up.

Case ReportsThe excimer laser sheath technique for embedded inferior vena cava filter removal.
An inferior vena cava (IVC) filter became embedded within the IVC of a 45-year-old man after prolonged implantation. Because of incorporation of the filter legs within the caval endothelium, the filter was densely adherent and could not be sheathed using standard retrieval methods. In this patient, the authors performed percutaneous filter retrieval using an excimer laser sheath technique for circumferential ablation of dense fibrotic tissue between the filter and IVC. Endovascular laser ablation allowed facile separation of the filter from the IVC, without tearing of the tissues, and the filter was removed successfully without complication.
