MRI estimation of total renal volume demonstrates significant association with healthy donor weight.

Purpose: The purpose of this study was to correlate total renal volume (TRV) calculations, obtained through the voxel-count method and ellipsoid formula with various physical characteristics.

Materials And Methods: MRI reports and physical examination from 210 healthy kidney donors (420 kidneys), on whom renal volumes were obtained using the voxel-count method, were retrospectively reviewed. These values along with ones obtained through a more traditional method (ellipsoid formula) were correlated with subject height, body weight, body mass index (BMI), and age.

Preoperative selective venous sampling for nonlocalizing parathyroid adenomas.

Introduction: Preoperative parathyroid adenoma localization allows for a minimally invasive surgical approach. Current methods used for adenoma localization include ultrasound, sestamibi scan, and occasionally magnetic resonance imaging (MRI). In cases in which an adenoma is not localized after a radiologic work-up, the surgeon must perform a four-gland exploration.

Inferior mesenteric artery embolization before endovascular aneurysm repair: technique and initial results.

Purpose: To report a single center's technique and initial results in the preoperative embolization of the inferior mesenteric artery (IMA) before endovascular aneurysm repair (EVAR).

Materials And Methods: Over a 3-year period, 102 patients at a single clinical site, including 86 men and 16 women aged 54-93 years (mean, 75 years), were found to have a patent IMA on computed tomographic (CT) angiography before EVAR. Coil embolization was performed after subselective catheterization with use of microcoils placed in the IMA proximal to the origin of the left colic artery.

Guide wire perforation leading to fatal perirenal hemorrhage from transcortical collaterals after renal artery stent placement.

After successful renal artery angioplasty and stent placement, a patient in a fully anticoagulated state developed hypotension and flank pain. Review of the intraprocedural angiogram demonstrated transcortical position of the guide wire. Computed tomography of the abdomen revealed a large perinephric hematoma.
