We evaluated retrospectively 1554 arteriographies of hypertensive patients. Angiograms were evaluated to find RAS, significant RAS (>60% stenosis of the lumen), radiological signs of atherosclerosis, aneurysms of the renal arteries or aorta and variants of kidney vascularization. The frequency of RAS including occlusions was 15.1% (21.3% of them were significant and suitable for revascularization). Anlotinib Variants of renal arterial vascularization were found in 26.5% of patients (multiple renal arteries-11.2%

and accessory renal arteries-15.3%). Significant RAS was found more frequently in patients older than 60 years-OR 4.76 (2.08-10.86). Coronary artery disease, history of myocardial infarction or stroke significantly increased the chance of RAS detection. The frequency of renal accessory arteries was lower in patients older than 60 years and in patients with the radiological signs of atherosclerosis. Results of this study indicate that haemodynamically important RAS is found more

frequently in hypertensive patients older than 60 years. Symptomatic atherosclerotic disease found in the peripheral and/or coronary arteries and diabetes mellitus increases the chance of RAS detection. Decreased occurrence of renal accessory arteries was found in hypertensive patients with radiological signs of atherosclerosis.

“Background: The perioperative diagnosis of infection in the setting of revision elbow arthroplasty may be difficult to establish. Intraoperative pathology with histology for identification of acute inflammatory changes has been reported to be of value in revision surgery

after failed hip or knee arthroplasty. The purpose of this study was to study the role of intraoperative histology in the diagnosis of infection in patients undergoing revision elbow arthroplasty.

Methods: From 2000 to 2007, 296 consecutive revision elbow procedures were performed at our institution. Both intraoperative histology and operative samples for culture were obtained at the time of 227 of these procedures, which form the basis of this study.

Results: Histology was read as consistent with acute inflammation in patients undergoing thirty-three procedures (14.5%). Intraoperative cultures were positive in thirty-nine procedures (17.2%). Intraoperative histology was considered true positive (both histology and cultures positive) in twenty arthroplasties (8.8%), true negative (both histology and cultures were negative) in 175 arthroplasties (77.1%), false positive (the histology was positive but the culture was negative) in thirteen arthroplasties (5.7%), and false negative (the histology was negative but the culture was positive) in nineteen arthroplasties (8.
