Blueprint for Implementing and Improving Eligible Inferior Vena Cava Filter Retrieval Across Institutions.

Introduction: Placement of removable inferior vena cava filters (rIVCFs) has increased, but this has not been accompanied by timely removal, with retrieval rates as low as 8.5% at some institutions. Failure to remove rIVCFs that were not medically necessary resulted in increased complications.

Spontaneous Bleeding From Multiple Intercostal Arteries in a Patient With Coarctation of the Aorta.

A 59-year-old man with a history of coarctation repair, mechanical aortic valve, and warfarin therapy presented with right flank pain. Computed tomography showed a large hematoma encircling an intact descending thoracic aorta. Computed tomography angiography demonstrated multiple areas of intercostal artery extravasation.

Iron deposition is independent of cellular inflammation in a cerebral model of multiple sclerosis.

Background: Perivenular inflammation is a common early pathological feature in multiple sclerosis (MS). A recent hypothesis stated that CNS inflammation is induced by perivenular iron deposits that occur in response to altered blood flow in MS subjects. In order to evaluate this hypothesis, an animal model was developed, called cerebral experimental autoimmune encephalomyelitis (cEAE), which presents with CNS perivascular iron deposits.
