Imaging and evaluation of coronary artery bypass graft patency by 16-slice multidetector computed tomography.

Introduction: The purpose of this study was to evaluate the patency of coronary artery bypass grafts (CABGs) while assessing the capabilities and limitations of 16-slice multidetector computed tomography.

Methods: We studied retrospectively 19 patients (13 men, 6 women), over an 18-month period. All patients had undergone CABG surgery 3 months to 7 years earlier.

Clinical experience with Günther temporary inferior vena cava filters.

This retrospective study was performed to evaluate the safety and effectiveness of Günther temporary inferior vena cava (IVC) filters. Fifteen Günther temporary filters were placed in 13 patients because of deep vein thrombosis (DVT) with pulmonary embolism (PE) despite DVT prophylaxis (9/13) or temporary contraindications for anticoagulants as well as recent or pending surgery (4/13). No clinical manifestation of PE was observed during the filtration or during the removal.
