  • Measuring health related quality of life in patients with rheumatoid arthritis--reliability, validity, and responsiveness of a Swedish version of RAQoL.
  • 2002
  • Ingår i: Scandinavian Journal of Rheumatology. - : Informa UK Limited. - 1502-7732 .- 0300-9742. ; 31:1, s. 6-12

    • OBJECTIVE: To adapt the Rheumatoid Arthritis Quality of Life (RAQoL) questionnaire for Swedish patients and evaluate psychometric properties in a prospective study. METHODS: Reliability was assessed in 61 patients filling in RAQoL two times with one week's interval. 114 patients completed RAQoL and Nottingham Health Profile (NHP) on 2-3 occasions 6 months apart. Validity was evaluated comparing RAQoL-scores to disease-related variables and NHP subscales. Standardized response mean was applied to calculate responsiveness with the RA-related variables as external indicators of change. RESULTS: Test-retest reliability was high and internal consistency sufficient. RAQoL correlated as expected to NHP section scores. In a multivariate model the Stanford Health Assessment Questionnaire disability index (HAQ) and general health could explain 40% and disease activity measures 13% of the variance of RAQoL. Correlations between change scores of clinical variables and RAQoL and NHP were weak but positive. Standardized response means regarding change of disease activity, HAQ, and general health were small but in the same range for both RAQoL and NHP. CONCLUSION: The Swedish RAQoL had similar measurement properties as the original version. However, responsiveness regarding condition specific measures was not better than for the generic instrument NHP.

  • Long-term results after endovascular repair of abdominal aortic aneurysms with the Stentor and Vanguard stent-graft.
  • 2004
  • Ingår i: Acta Radiologica. - : SAGE Publications. - 1600-0455 .- 0284-1851. ; 45:3, s. 275-283
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: To present a single institution experience of long‐term results after endovascular repair of abdominal aortic aneurysms (AAA) with the Stentor and Vanguard stent‐grafts. Material and Methods: Twenty‐three patients (20 men, 3 women; mean age 68 years, range 53–81 years) were included in this prospective study. A first generation nitinol stent‐graft (Stentor™) was used in 12 patients and a second generation (Vanguard™) in 11 patients. Follow‐up was performed with magnetic resonance imaging (MRI) with contrast‐enhanced MR angiography (CE MRA) at 1, 6, and 12 months, and thereafter annually (median follow‐up 3 years; range 8 months to 8 years). A conventional radiograph of the abdomen was also performed. Before secondary intervention the findings on MRI with CE MRA were confirmed with spiral computed tomography (CT) and/or angiography (DSA). Results: Only one patient (4%) had no complication. Endoleak was found in 15 patients (65%), graft migration in 8 (35%), and graft deformation in 18 (78%). Secondary endovascular repair was required in 7 patients (30%) and 7 (30%) were converted to open repair. Conclusion: Complications with the Stentor and Vanguard stent‐grafts were common. Long‐term follow‐up of endovascularly repaired AAA is mandatory.

  • MR evaluation ex vivo and in vivo of a covered stent-graft for abdominal aortic aneurysms: ferromagnetism, heating, artifacts, and velocity mapping
  • 2000
  • Ingår i: Journal of Magnetic Resonance Imaging. - 1522-2586. ; 12:1, s. 112-121
  • Tidskriftsartikel (refereegranskat)abstract
    • Magnetic resonance imaging (MRI) safety was evaluated at 1.5 T in a covered nickel titanium stent-graft (Vanguard) used for endovascular treatment of abdominal aortic aneurysms (AAAs). Imaging artifacts were assessed on MRI with contrast-enhanced (CE) three-dimensional (3D) MR angiography (MRA) and spiral computed tomography (CT) in 10 patients as well as ex vivo. Velocity mapping was performed in the suprarenal aorta and femoral arteries in 14 patients before and after stent-graft placement. For comparison it was also performed in six healthy volunteers. No ferromagnetism or heating was detected. Metal artifacts caused minimal image distortion on MRI/MRA. The artifacts disturbed image evaluation on CT at the graft bifurcation and graft limb junction. No significant differences in mean flow were found in patients before and after stent-graft placement. Our study indicates that MRI at 1.5 T may be performed safely in patients with the (Vanguard) stent-graft. MRI/MRA provides diagnostic image information. Velocity mapping is not included in our routine protocol.
