Evaluation of treatment response of chemoembolization in hepatocellular carcinoma with diffusion-weighted imaging on 3.0-T MR imaging.
To assess the treatment response of hepatocellular carcinoma (HCC) after transarterial chemoembolization with diffusion-weighted imaging and dynamic contrast-enhanced magnetic resonance (MR) imaging with a 3-T system. ⋯ After transarterial chemoembolization, responding HCC lesions exhibited decreases in arterial enhancement and increases in ADC values in cellular and necrotic areas. Pretreatment ADC values were not predictive of response to chemoembolization.

Temporal assessment of splenic function in patients who have undergone percutaneous image-guided splenic artery embolization in the setting of trauma.
The role of transcatheter splenic arterial embolization (SAE) in the nonoperative management of splenic injury is evolving. The purpose of this study is to evaluate patients who have undergone SAE for laboratory markers of hyposplenism in the years after their procedure. ⋯ Phagocytic function of the spleen in patients who have undergone SAE is preserved, as evidenced by the absence of HJBs on follow-up peripheral blood smears.

Delayed complications following technically successful thoracic duct embolization.
Thoracic duct (TD) embolization (TDE) has become a universally accepted treatment of chylous pleural effusion. However, the long-term sequelae of occlusion of the TD are unknown. The objective of the present study was to determine the rate of delayed complications after technically successful TDE. ⋯ Chronic diarrhea and lower-extremity swelling may be related to TDE and should be part of informed consent before the procedure. A prospective follow-up study is needed to further establish these relationships.

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.
