ReviewReview of venous anatomy for venographic interpretation in chronic cerebrospinal venous insufficiency.
Chronic cerebrospinal venous insufficiency (CCSVI) represents a recently described condition that may potentially contribute to the symptoms experienced by patients with multiple sclerosis. The evaluation of a prospective patient for CCSVI often involves an invasive evaluation with venography of the internal jugular and azygos veins. The purpose of this article is to review the normal anatomy of the internal jugular, vertebral, and azygos veins, as an understanding of these veins is necessary for appropriate interpretation of the venograms obtained to evaluate patients for CCSVI.

Percutaneous vertebroplasty for vertebral compression fractures with intravertebral cleft: cement injection under vacuum aspiration.
To evaluate the efficacy of cement injection under vacuum aspiration (CIVAS) of cleft contents in percutaneous vertebroplasty for osteoporotic vertebral compression fractures with an intravertebral cleft. ⋯ The CIVAS method is feasible and appears to improve cleft filling in the treatment of single-level vertebral compression fractures with a cleft, compared with conventional cement injection.

Postpartum hemorrhage in coagulopathic patients: preliminary experience with uterine arterial embolization with N-butyl cyanoacrylate.
The present report describes uterine artery embolization (UAE) with N-butyl cyanoacrylate (NBCA) in four patients with postpartum hemorrhage (PPH) in a coagulopathic condition. Initial UAE with gelatin sponge particles and/or fibered platinum microcoils had failed in these patients. ⋯ One patient resumed menstruation in 6 months. NBCA may be a promising embolic material for emergent UAE in patients with PH, especially for patients with a coagulopathic condition.
