Pneumothorax following ultrasound-guided jugular vein puncture for central venous access in interventional radiology: 4 years of experience.

Purpose: The purpose of our study was to review the rate of pneumothorax following central venous access, using real-time ultrasound guidance.

Materials And Methods: Data related to ultrasound-guided venous puncture, for central venous access, performed between July 1, 2004 and June 30, 2008 was retrospectively and prospectively collected. Access route, needle gauge, catheter type, and diagnosis of pneumothorax on the intraprocedure spot radiographs and or the postprocedure chest radiographs, were recorded.

Focal nodular hyperplasia: central scar enhancement pattern using Gadoxetate Disodium.

Purpose: To illustrate the unusual enhancement pattern of the focal nodular hyperplasia central scar using Gadoxetate Disodium.

Materials And Methods: Over a 10-month period, six patients, with a total of seven focal nodular hyperplasia lesions with typical central scar, had MRI of the liver using Gadoxetate Disodium (Eovist, Bayer HealthCare Pharmaceuticals Inc., Wayne, NJ).

Microcoil embolization for acute lower gastrointestinal bleeding.

Purpose: To assess outcomes after microcoil embolization for active lower gastrointestinal (GI) bleeding.

Methods: We retrospectively studied all consecutive patients in whom microcoil embolization was attempted to treat acute lower GI bleeding over 88 months. Baseline, procedural, and outcome parameters were recorded following current Society of Interventional Radiology guidelines.
