Case ReportsAcetic acid sclerotherapy for treatment of a biliary leak from an isolated bile duct after hepatic surgery.
Bile duct leakage from the main biliary tree is not uncommon after hepatic surgery. In this case, successful percutaneous treatment was performed for bile leakage from an isolated bile duct after left hemihepatectomy in a 48-year-old woman who underwent surgery for biliary cystadenocarcinoma and developed a biloma at the left subphrenic space. Diagnostic procedures revealed that the right posterior segmental bile duct drained aberrantly into the left bile duct, which remained undrained after resection and led to biloma formation. Ablation of the isolated bile duct was performed with acetic acid, resulting in avoidance of repeated operation and other complications.

Renal blood flow measurements with use of phase-contrast magnetic resonance imaging: normal values and reproducibility.
To assess the validity and the direct, short-term, and long-term reproducibility of renal blood flow (RBF) measurements with phase-contrast (PC) magnetic resonance (MR) imaging. ⋯ RBF measurement with PC MR has a success rate greater than 75%. The demonstrated internal reliability of this method and fair reproducibility of the flow parameters is crucial for further studies of the renal artery with MR imaging.

Spinal CT-guided interventional procedures for management of chronic back pain.
Image-guided interventional procedures have arisen as an alternative for management of back pain, with controversial indications and efficacy. This study describes the technique, clinical impact, and complications of computed tomography (CT)-guided infiltrations for the management of chronic back pain. ⋯ Spinal CT-guided infiltration constitutes an effective therapy for chronic back pain. This series confirms a low complication rate, good response, and high therapeutic value.

Efficacy of manual aspiration immediately after complicated pneumothorax in CT-guided lung biopsy.
The goal of this study was to evaluate the efficacy of simple aspiration of air from the pleural space to prevent increased pneumothorax and avoid chest tube placement in cases of pneumothorax after computed tomography (CT)-guided lung biopsy. ⋯ Percutaneous manual aspiration of biopsy-induced pneumothorax performed immediately after biopsy may prevent progressive pneumothorax and eliminate the need for chest tube placement. However, in cases in which the amount of aspirated air is large (such as more than 543 mL in this study), the possibility of required chest tube placement increases.
