    Computed tomography findings in traumatic fractures of thoracic and lumbar vertebrae
    (Derman Medical Publishing secretary@jcam.com.tr, 2016) Ayaz, Ümit Yas?ar; Tüzün, Meri?; Ayaz, Sevin; Teber, Mehmet Akif; Heki?moğlu, Baki
    Aim: We aimed to differentiate major traumatic fractures of thoracic and lumbar vertebrae by using axial computed tomography (CT) images. Material and Method: Axial CT images of 14 patients (nine males, five females) who were diagnosed to have acute thoracic and lumbar spinal injuries, including only compression and/or burst fractures, were evaluated in this retrospective study. Denis classification was used. Results: In 64.3% (n=9/14) of the patients fractures occurred as the result of a fall and in 35.7% (n=5/14) of the patients the reason for the fracture was reported to be a traffic accident. In 78.6% (n=11/14) of the patients, no signs of spinal cord/nerve root injury could be detected at physical examination and in 21.4% (n=3/14) of the patients there were signs of spinal cord/nerve root injury. Of the fractured vertebrae, 86.7% (n=13/15) were lumbar and 13.3% (n=2/15) were thoracic. The thoracolumbar junction (T11-L2) was the most frequent site (73.3%, n=11/15) for compression and burst fractures, L1 being the most frequently involved vertebra (53.3%, n=8/15). Compression and burst fractures were demonstrated in 53.3% (n=8/15) and 46.7% (n=7/15) of the vertebrae, respectively. In 71.4% (n=5/7) of the burst fractures, displacement of bony fragments into the spinal canal (retropulsion) were demonstrated and in 60% (n=3/5) of the patients with retropulsion, serious neurological deficits were present. Discussion: More than 2/3 of the traumatic vertebral fractures were detected in the thoracolumbar junction (T11-L2). Axial CT images are effective in differentiating compression and burst fractures of thoracic and lumbar vertebrae. © 2017 Elsevier B.V., All rights reserved.

    Use of the Amplatzer Type 2 Plug for Flow Redirection in Failing Autogenous Hemodialysis Fistulae
    (Springer, 2015) Bozkurt, Alper; Kirbas, Ismail; Kasapoglu, Benan; Teber, Mehmet Akif
    To present our experience with redirecting the outflow of mature arteriovenous fistulae (AVFs) in patients with cannulation and/or suboptimal flow problems by percutaneous intervention using the Amplatzer Vascular Plug II (AVP II). We retrospectively reviewed patients who presented with difficulty in cannulation and/or suboptimal flow in the puncture zone of the AVF and who underwent intervention using the AVP II to redirect the outflow through a better cannulation zone from March 2009 to November 2012. The mean survival rate of all AVFs was estimated, and the effects of patient age, sex, and AVF age on the AVF survival time were determined. In total, 31 patients (17 male and 14 female) with a mean age of 57.8 years (range, 20-79 years) were included. In 2 patients, the AVF failed within the first 15 days because of rapid thrombosis. In 9 patients, the new AVF route was working effectively until unsalvageable thrombosis developed. One of the 31 patients died 9 months before the last radiologic evaluation. The new AVF route was still being used for dialysis in the remaining 19 patients. The mean AVF survival rate was 1,061.4 +/- A 139.4 days (range, 788-1,334 days). Patient age, sex, and AVF age did not affect the survival time. We suggest that the AVP II is useful for redirecting the outflow of AVFs with cannulation problems and suboptimal flow. Patency of existing AVFs may be extended, thereby extending surgery-free or catheter intervention-free survival period.
