Vacuum-assisted closure for postcardiac surgery mediastinitis in a patient on hemodialysis.

A 66-year-old man on hemodialysis underwent off-pump coronary artery bypass grafting. He was discharged in good condition on postoperative day (POD) 16. A high-grade fever and a purulent discharge emerged on POD 30.

Dynamic MRI for distinguishing high-flow from low-flow peripheral vascular malformations.

Objective: The purpose of our study was to assess the usefulness of dynamic MRI in distinguishing high-flow vascular malformations from low-flow vascular malformations, which do not need angiography for treatment.

Subjects And Methods: Between September 2001 and January 2003, 16 patients who underwent conventional and dynamic MRI had peripheral vascular malformations (six high- and 10 low-flow). The temporal resolution of dynamic MRI was 5 sec.
