PURPOSE The aim of this study was to determine the value of power Doppler ultrasonography in the differential diagnosis of intracranial extraaxial fluid collections in enlarged subarachnoid spaces. MATERIALS AND METHODS The study included 11 patients referred to our hospital's radiology department between April 2001 and February 2002 who were determined to have intracranial extraaxial effusio...

The use of intraoperative ultrasonography (IOUS) to evaluate liver, bile ducts and pancreatic disease, as compared to the results of preoperative ultrasonography and CT, is discussed. Forty-two patients who underwent abdominal surgery for suspected hepatobiliary and/or pancreatic diseases were studied. The intraoperative study was carried out with a portable apparatus (Aloka 500, Japan), using ...

Purpose. The purpose of this study was to assess nerve hypervascularization using high resolution ultrasonography to determine the effects of wrist posture and fingertip force on median nerve blood flow at the wrist in healthy participants and those experiencing carpal tunnel syndrome (CTS) symptoms. Methods. The median nerves of nine healthy participants and nine participants experiencing symp...

Ultrasonography has become available to most physicians in primary care. Increasingly hepatic steatosis becomes a chance finding, which has been shown to be associated with cardiovascular risk factors, surrogates of vascular disease, and vascular events. This study tries to answer the question whether it is justified to recommend a cardiovascular workup in response to the incidental finding of ...

Central venous catheterization is of common practice in intensive care units; despite representing an essential device in various clinical circumstances, it represents a source of complications, sometimes even fatal, related to its management. We report the removal of a central venous catheter (CVC) that had been wrongly positioned through left internal jugular vein. The vein presented complete...

OBJECTIVE To assess the value of quantitative vascular imaging by power Doppler US (PDUS) as a tool that can be used to stratify patient risk of joint damage in early seropositive RA while still biologic naive but on synthetic DMARD treatment. METHODS Eighty-five patients with seropositive RA of <3 years duration had clinical, laboratory and imaging assessments at 0 and 12 months. Imaging ass...

This clinical study was performed to investigate the patency rate of endothelial cell-seeded small-diameter expanded polytetrafluoroethylene grafts during coronary artery bypass surgery. Between September 1995 and December 1998, 14 patients (median age: 71 years, range: 61-79 years) received 21 endothelial cell-seeded small-diameter grafts. In all, 43% of the performed implantations were reoper...

BACKGROUND Incidence of radial artery occclusions (RAO) and ulnar artery occclusions (UAO) in coronary procedures, factors predisposing to forearm arteries occlusion, and the benefit of anticoaggulation vary significantly in existing literature. We sought to determine the incidence of RAO/UAO and the impact of anticoagulation intensity. METHODS AND RESULTS Meta-analysis of 112 studies assessi...

PURPOSE To evaluate the effect of hormone replacement therapy on ocular hemodynamics in postmenopausal women. METHODS Ocular Doppler ultrasonography was performed in 20 postmenopausal women on hormone replacement therapy (HRT) and in 20 women without treatment, as the control group. Central retinal artery (CRA), posterior ciliary artery (PCA) and ophthalmic artery (OA) flow velocities and vas...

BACKGROUND This study examined whether patellar tendon vascularity could be quantified accurately in the clinical setting using colour Doppler ultrasonography. METHODS A sonographer and two radiologists visually estimated tendon vascularity in millimetres in 74 tendons during ultrasound (US) examination and from hard copy films. These estimates were then compared to the length of vessels meas...
