Prospective Evaluation of the TIGRIS Vascular Stent Within a Modern Treatment Algorithm.

To prospectively evaluate the safety and efficacy of the TIGRIS Vascular Stent in the superficial femoral artery (SFA) and proximal popliteal artery within a treatment algorithm that reserved stent usage for more challenging patients. This prospective, single-center study enrolled 97 patients (mean age 68.7 years; 66 men) who were treated for 100 de novo or nonstented restenotic femoropopliteal lesions (≥70% stenosis) and had recoil or dissection after plain balloon predilation.

Angio-Seal use in patients with peripheral arterial disease (ASPIRE).

Purpose: To investigate the incidence of complications after the use of an arterial closure device (Angio-Seal) in patients with peripheral arterial disease.

Methods: In 105 consecutive patients after transfemoral catheterization, the puncture site was closed using a closure device (Angio-Seal). Colour-flow-duplexsonography studies were conducted 1 to 4 days before, within 3 days after and 3 month after the intervention.

Arthrogryposis multiplex congenital in a child manifesting phenotypic features resembling dysosteosclerosis/osteosclerosis malformation complex; 3DCT scan analysis of the skull base.

Introduction: A boy presented with arthrogryposis multiplex congenita (AMC) associated with severe central nervous system dysfunction. The clinical history and the distinctive radiographic/tomographic features were consistent but not completely diagnostic for dysosteosclerosis.

Case Presentation: A 5-year-old boy from a consanguineous family in Austria was born with arthrogryposis multiplex congenita in connection with central nervous system dysfunction.

Cancellous bone structure in the growing and aging lumbar spine in a historic Nubian population.

There is abundant data on cancellous bone in the aging human spine, but little relating to the growing vertebral cancellous bone in childhood an adolescence. The purpose of this study was to map vertebral cancellous bone in a growth and age series of historic skeletal samples and to make comparisons with data published on recent material. Lumbar vertebral bodies were collected from 65 skeletons (0-60 years) from a medieval Nubian population.

Age- and sex-dependent cancellous bone changes in a 4000y BP population.

We studied cancellous bone loss in a 4000y BP population, using several methods designed to detect age-related changes, in order to investigate the pattern of cancellous bone loss in this ancient population and to compare the results deriving from different methods used on identical specimens. We used 10-mm sections of fourth lumbar vertebral bodies and left femoral necks of 18 individuals of both sexes with estimated ages from 20 to 60 years of a 4000y BP bronze-age population. Stereoscopic photographs were used for three-dimensional analysis and trabecular number (TN) counting.

[DEXA (dual-energy x-ray absorptiometry) and DPA (dual photon absorptiometry) in densitometry of the femoral neck: correlation of the measurements of three commercially available instruments].

The bone mineral density measurements of three different instruments at the femoral head were compared using 12 cadaver specimens. Two of these instruments were operated by x-rays (dual energy x-ray absorptiometry = DEXA), whereas one system was based on a gadolinium source (dual photon absorptiometry = DPA). Although excellent correlation between the measurements was obtained (r greater than 0,9), the measurements of one of the DEXA-instruments were significantly higher than the measurements of the two other systems.
