An Ex Vivo Phantom Validation Study of an MRI-Transrectal Ultrasound Fusion Device for Targeted Prostate Biopsy.

Objectives: To evaluate the ex vivo accuracy of an MRI-TRUS fusion device for guiding targeted prostate biopsies, to identify the origin of errors, and to evaluate the likelihood that lesions can be accurately targeted.

Materials And Methods: Three prostate phantoms were used to perform 27 biopsies using transperineal MRI-TRUS fusion. All phantoms underwent 3-T MRI.

Percutaneous transluminal angioplasty of the infrarenal aorta: initial outcome and long-term clinical and angiographic results.

Objective: Report of 1-8 year follow-up of patients treated by percutaneous transluminal angioplasty (PTA) for obstructive atherosclerosis of the infrarenal aorta.

Design: Cohort study.

Materials: Thirty-eight patients aged 26-81 years (mean 50 years) were submitted to undergo percutaneous transluminal angioplasty of the infrarenal aorta.

Perforation of a vascular prosthesis by an eroded thoracic vertebral body.

A case of prosthetic graft rupture due to friction against the vertebral column, eroded by a previously repaired thoracic aortic aneurym, is described. Chiselling away the sharp bony edges of the eroded vertebrae, could have prevented this complication. To our knowledge, this complication has never been reported before.
