Does Timing of Inferior Vena Cava Filter Retrieval Planning Impact Retrieval Rates? A Comparison of Planning Before or After Hospital Discharge.

Introduction: Indwelling inferior vena cava (IVC) filters are associated with complications, and the US Food and Drug Administration recommends their prompt removal when no longer indicated. Therefore, assessing strategies for increasing retrieval rates is warranted.

Objective: To analyze the variability of IVC filter retrieval rates within our institution based on 2 separate, pre-existing processes in which IVC retrieval is planned for before or after hospital discharge.

Computed tomography, magnetic resonance, and ultrasound imaging: basic principles, glossary of terms, and patient safety.

The basic principles underlying computed tomography, magnetic resonance, and ultrasound are reviewed to promote better understanding of the properties and appropriate applications of these 3 common imaging modalities. A glossary of frequently used terms for each technique is appended for convenience. Risks to patient safety including contrast-induced nephropathy, radiation-induced malignancy, and nephrogenic systemic fibrosis are discussed.

Delayed neurologic deficit after infrarenal endovascular aortic aneurysm repair.

Spinal cord ischemia is a rare and devastating complication after elective abdominal aortic aneurysm repair. It has recently been reported to occur after endovascular aortic aneurysm repair. We report the first case of delayed neurologic deficit after endovascular aortic aneurysm repair using the Zenith (Cook) device.
