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)
BACKGROUND In up to 4% of laparoscopic Roux-en-Y gastric bypass (LRYGB) procedures, anastomotic leaks occur. Early detection of gastrointestinal leakage is important for successful treatment. Consequently, many centers advocate routine postoperative upper gastrointestinal (UGI) series. The aim of this study was to determine the utility of this practice(More)
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. Five repeated straylight measurements were taken using the dominant eye of 45(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 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)
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)
Background: To evaluate the safety of immediate sequential bilateral cataract extraction (ISBCE) with respect to indications, visual outcomes, complications, benefits and disadvantages. Methods: This is a retrospective review of all ISBCEs performed at Kantonsspital Winterthur, Switzerland, between April 2000 and September 2013. The case notes of 500 eyes(More)
To evaluate visual recovery and intraocular straylight in keratoconus patients 3 months and 1 year after corneal crosslinking (CXL) 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 acuity (CDVA), intraocular(More)
BACKGROUND To evaluate the predictability of refraction following immediate sequential bilateral cataract surgery (ISBCS) performed under general anaesthesia. METHODS This is a retrospective review of all ISBCS performed at Kantonsspital Winterthur, Switzerland, between April 2000 and September 2013. The case notes of 250 patients were reviewed.
