Cephalic arch restenosis rates in hemodialysis patients with brachiocephalic fistulae: a retrospective multicenter analysis of 3301 patients.

Background: We evaluated restenosis rates at the cephalic arch after percutaneous angioplasty and stenting procedures in patients with brachial artery to cephalic vein arteriovenous fistula (BCAVF) hemodialysis access.

Methods: We used data from adult hemodialysis patients treated at a national network of 44 outpatient interventional facilities during Oct 2011-2015. We included data from patients with BCAVF who received an exclusive angioplasty, or stent with angioplasty, for treatment of cephalic arch stenosis and had ≥1 subsequent evaluation of the cephalic arch.

Intramedullary Cervical Sarcoidosis as the Initial Presentation of Systemic Sarcoidosis.

We present a case of a 57-year-old African American man with systemic sarcoidosis, who initially presented with cervical spinal cord disease. Initial MRI showed an elongated intramedullary area of increased signal intensity on T2 and inversion recovery sequences within the cervical spinal cord with minimal contrast enhancement after gadolinium administration. Further radiologic evaluation led to a chest CT, which showed bilateral hilar lymphadenopathy.

Ultrasound-Guided Removal of an Infected Loose Body from the Quadriceps Muscle.

We present the case of a 35 year-old male with pain and swelling in his right thigh. By CT and sonography, an abscess was localized to the deep, anteromedial, mid-thigh within the quadriceps muscle, along with a 1.3 cm loose body.
