Duplex ultrasound criteria for in-stent restenosis of mesenteric arteries.

Objective: Duplex ultrasound (DUS) criteria are well defined for evaluating high-grade stenosis (≥70%) of the native superior mesenteric artery (SMA) and celiac artery (CA). It has been shown that native vessel criteria overestimate the degree of in-stent restenosis (ISR) and that velocity criteria for SMA and CA ISR are not well established. The objective of this study was to define DUS velocity criteria for high-grade ISR of the SMA and CA.

Arteriovenous graft configuration in hemodialysis: does it matter?

Purpose: The current guidelines for arteriovenous graft (AVG) configuration in hemodialysis state the following sequence: forearm loop, upper arm straight or curved and upper arm looped. These recommendations are based upon literature from the 1980s. Modern patient demographics and patient treatment algorithms, i.

Outcomes of combined somatosensory evoked potential, motor evoked potential, and electroencephalography monitoring during carotid endarterectomy.

Background: While much has been written about multiple methods of neuromonitoring during carotid endarterectomy (CEA), there has been relatively little discussion of the use of triple monitoring via somatosensory evoked potentials (SEPs) and motor evoked potentials (MEPs) in conjunction with electroencephalography (EEG). Our objective was to evaluate the rate of detection and prevention of neurologic events by multinerve SEP, MEP, and EEG in patients undergoing CEA while under general anesthesia.

Methods: A prospective study of 181 consecutive patients undergoing CEA between June 2005 and September 2010 was reviewed.

Simplified method for candidate selection for radial artery harvesting.

With the renewed interest in the use of autogenous radial arteries in coronary artery bypass grafting, concerns regarding vascular compromise and selection of patients have arisen. In this report, we describe a modification of Allen's test.

Surgery for angina pectoris--historical aspects.

The history of surgery for ischemic heart disease is presented beginning with procedures to ablate nerves to the heart in the early part of this century. The evolution of surgical techniques to primary coronary artery bypass grafting is illustrated. Included are subtotal thyroidectomy, pedicle grafting of muscle, omentum, lung, stomach, and jejunum to the pericardium and heart, cardiopericardiopexy, ligation of the great cardiac vein, grafting from aorta to coronary sinus, implantation of arteries into the myocardium, coronary artery bypass grafting, and percutaneous transluminal coronary angioplasty.
