Gross hemoglobinuria and oliguria are common transient complications of sclerotherapy for venous malformations: review of 475 procedures.
The purpose of this article is to study the incidence, risk factors, and treatment of gross hemoglobinuria and oliguria following sclerotherapy for venous malformations. ⋯ Transient hemoglobinuria and oliguria are common complications of sclerotherapy for venous malformation. Nevertheless, with proper fluid management, all the patients promptly recovered. The risk correlates with the volume of sclerosant (adjusted to patient's weight) and is higher for lower extremity and multiple locations.

ReviewThe novel oral anticoagulants: an update for the interventional radiologist.
Thromboembolic disorders are leading causes of morbidity and mortality, with treatment and prophylaxis a priority. There has been a heavy dependency upon warfarin and heparin for anticoagulation for 60 years. This is likely to change with the emergence of novel oral anticoagulants. ⋯ Interventional radiologists are increasingly encountering these medications, and a thorough knowledge of them is essential for appropriate periprocedural management. This article will review these novel agents, their uses, and their pharmacologic profiles and will propose guidelines for periprocedural management.

High-resolution STIR for 3-T MRI of the posterior fossa: visualization of the lower cranial nerves and arteriovenous structures related to neurovascular compression.
Preoperative evaluation of small vessels without contrast material is sometimes difficult in patients with neurovascular compression disease. The purpose of this retrospective study was to evaluate whether 3D STIR MRI could simultaneously depict the lower cranial nerves--fifth through twelfth--and the blood vessels in the posterior fossa. ⋯ High-resolution STIR is a feasible method for simultaneous evaluation of the lower cranial nerves and the vessels in the posterior fossa without the use of contrast material.

Overnight subspecialty radiology coverage: review of a practice model and analysis of its impact on CT utilization rates in academic and community emergency departments.
The purpose of this study is to describe a new practice model (overnight subspecialty radiology coverage) and to determine its impact on CT utilization rates in academic and community emergency departments. ⋯ Institution of overnight subspecialty emergency department coverage resulted in a disproportionate increase in CT utilization in community emergency departments. We hypothesize that community emergency departments lacking in-house clinical subspecialists may be more apt to use subspecialist radiology interpretations for patient management. Overnight subspecialty coverage increases CT utilization in the community emergency department, but the appropriateness and clinical impact is uncertain and in need of exploration.

The purpose of our study was to assess the normal range of CT measures of emphysema and air trapping in young men with normal lung function. ⋯ We report the normal range of CT values for young male subjects with normal lung function, which is important to define pulmonary disease.
