    Stent Implantation in Chronic Mesenteric Ischemia
    (Royal Soc Medicine Press Ltd, 2009) Aksu, C.; Demirpolat, G.; Oran, I.; Demirpolat, G.; Parildar, M.; Memis, A.
    Background: Chronic mesenteric ischemia (CMI) is a life-threatening disorder, which is usually associated with stenosis or occlusion of celiac or mesenteric arteries. Purpose: To review our experience and to assess short-term results of stent placement in stenotic mesenteric arteries. Material and Methods: Primary stent placement was performed in 15 patients who had nausea, vomiting, postprandial pain, and weight loss due to steno-occlusive diseases of mesenteric arteries. After stenting, the patients were followed clinically and with Doppler ultrasound at 1, 6, and 12 months. Symptomatic patients with restenosis were examined with digital subtraction angiography and were referred for retreatment with balloon dilatation. Results: Twenty-three stenoses and 11 occlusions were detected in 15 patients, and 18 stenoses were treated with primary stenting. Single-vessel endovascular treatment was performed in 12 patients. In three patients, two arteries were stented in the same session. Technical success rate was 18/18 (100%). Clinical success was achieved in 13/15 (86.6%) patients. First-month mortality was 13%. During the mean 16.1-month follow-up period, restenoses developed in three patients. One of them was successfully treated with balloon angioplasty. Primary patency was 9/11 (81%) and primary assisted patency was 81% at 12 months. The complication rate was 1/15 patients (0.06%). Conclusion: Our experience suggests that stent placement has a potential role in chronic mesenteric ischemia with low incidence of complications and high technical and clinical success rates.

    The Ankylosing Spondylitis Quality of Life (ASQoL) questionnaire is a disease-specific measure of needs-based quality of life developed in the UK and the Netherlands. This study describes translation, validation, and reliability of the scale into Turkish population. The ASQoL was translated into Turkish using the dual-panel process. Content validity was assessed via cognitive debriefing interviews with ankylosing spondylitis (AS) patients. Patients with AS according to modified New York criteria were recruited into the study from 12 hospitals of all part of Turkey. Psychometric and scaling properties were assessed via a two administration survey involving the ASQoL, the Nottingham Health Profile (NHP), Bath AS Functional Index (BASFI), and Bath AS Disease Activity Index (BASDAI). Classical psychometrics assessed reliability, convergent validity (correlation of ASQoL with NHP, BASFI, and BASDAI) and discriminative validity (correlation of ASQoL with perceived AS-severity and general health). Cognitive debriefing showed the new Turkish ASQoL to be clear, relevant, and comprehensive. Completed survey questionnaires were received from 277 AS patients (80 % Male, mean age 42.2/SD 11.6, mean AS duration 9.4 years/SD 9.4). Test-retest reliability was excellent (0.96), indicating low random measurement error for the scale. Correlations of ASQoL with NHP sections were low to moderate (NHP Sleep 0.34; NHP Emotional Reactions 0.83) suggesting the measures assess related but distinct constructs. The measure was able to discriminate between patients based on their perceived disease severity (p < 0.0001) and self-reported general health (p < 0.0001). The Turkish version of ASQoL has good reliability and validity properties. It is practical and useful scale to assess the quality of life in AS patients in Turkish population.
