OBJECTIVE To investigate the performance of low-dose, dual-source computed tomography (DSCT) coronary angiography in the step-and-shoot (SAS) mode for the diagnosis of significant coronary artery stenoses in comparison with conventional coronary angiography (CCA). DESIGN, SETTING AND PATIENTS Prospective, single-centre study conducted in a referral centre(More)
PURPOSE To identify OCT-based anatomical features and clinical characteristics for poor central retinal thickness (CRT) response to ranibizumab in neovascular age-related macular degeneration (AMD). PATIENTS AND METHODS Investigating our electronic patient records (Eyeswide), patients with neovascular AMD treated with intravitreal injections of(More)
PURPOSE To evaluate visual recovery and intraocular straylight in keratoconus patients 3 months and 1 year after corneal crosslinking (CXL) PATIENTS AND METHODS: Thirty-three eyes of 28 consecutive patients with mild to moderate keratoconus were included. The following were assessed at baseline, 3 months and 1 year after CXL: corrected distance visual(More)
BACKGROUND Since 1994, laparoscopic Roux-en-Y gastric bypass (LRYGBP) has gained popularity for the treatment of morbid obesity. In analogy to open surgery, the operation was initially performed in a retrocolic fashion. Later, an antecolic procedure was introduced. According to short-term studies, the antecolic technique is favorable. In this study, we(More)
PURPOSE To provide evidence for the endovascular repair of patients with extracranial carotid artery dissection. MATERIALS AND METHODS A comprehensive literature review was performed whereby all studies that reported on the results of endoluminal repair of extracranial carotid artery dissection and provided information about primary technical and clinical(More)
PURPOSE To report the results of a systematic review of the literature and to provide evidence for the hybrid open-endovascular repair (HOER) in patients with thoracoabdominal aortic aneurysms (TAAAs). METHODS A comprehensive literature review was performed and all studies identified that reported the results of HOER in patients with TAAA and information(More)
BACKGROUND Straylight gives the appearance of a veil of light thrown over a person's retinal image when there is a strong light source present. We examined the reproducibility of the measurements by C-Quant, and assessed its correlation to characteristics of the eye and subjects' age. PARTICIPANTS AND METHODS Five repeated straylight measurements were(More)
BACKGROUND To evaluate the effectiveness of the Viabahn Open Revascularization Technique (VORTEC) in the treatment of thoracoabdominal aortic aneurysms (TAAAs) and pararenal aortic aneurysms (PAAAs) by hybrid procedures. METHODS Between December 2004 and March 2009, 58 patients (45 male, mean age, 74 years) were diagnosed with TAAA (n = 30) and PAAA (n =(More)
