BACKGROUND Accurate carotid imaging is important for effective secondary stroke prevention. Non-invasive imaging, now widely available, is replacing intra-arterial angiography for carotid stenosis, but the accuracy remains uncertain despite an extensive literature. We systematically reviewed the accuracy of non-invasive imaging compared with intra-arterial angiography for diagnosing carotid ste...

prom april, 1983 until december, 1987, 15 patients with horseshoe kidneys underwent surgery in shahid labbafi nejad medical center. pyelolithotomy was done in 11 cases, pyeloplasty in 2 cases, and nephrectomy in 2 cases. symphysiotomy was performed in 14 of these patients. preoperative angiography was not done in any of the cases and midline transperitoneal approach was utilized in all of the c...

background: percutaneous nephrolithotomy (pcnl) for renal calculi is less invasive treatment than open surgery. vascular complications of this procedure include hematoma, pseudoaneurysm and arteriovenous fistula of which pseudoaneurysm is usually symptomatic 24h after procedure. case report : we report a case of pseudoaneurysm, which was symptomatic within less than 24h following procedure and ...

INTRODUCTION The primary diagnostic examination performed in patients with a high pre-test probability of coronary artery disease (CAD) is invasive coronary angiography. Currently, approximately 50% of all invasive coronary angiographies do not end with percutaneous coronary intervention (PCI) because of the absence of significant coronary artery lesions. It is desirable to eliminate such situa...

In recent years MR Angiography allowed to assess blood vessels and flow in a non-invasive way. The aim of our work was illunstrate modern technique, the 4D Iterative reconstruction Time resolved angiography With Interleaved Stochastic Trajectories (IT-TWIST), capable generate angiograms with high spatial temporal resolution, providing multiple continuous post-contrastographic sets images. Techn...

AIMS The aim of our study was to investigate the accuracy of 64-slice computed tomography (CT) for assessing haemodynamically significant stenoses of coronary arteries. METHODS AND RESULTS CT angiography was performed in 67 patients (50 male, 17 female; mean age 60.1+/-10.5 years) with suspected coronary artery disease and compared with invasive coronary angiography. All vessels > or =1.5 mm ...

Pulmonary arteriovenous fistula is a congenital and rarely acquired anomalous direct communications between pulmonary arteries and veins. Transcatheter embolization using metallic coil or detachable balloon is one of the common treatment procedure. However, recanalization after the embolization is one of the concern and its differentiation from the retrograde filling via pulmonary vein is diffi...

CONTEXT Multislice computed tomography (MSCT) has recently evolved as a modality for noninvasive coronary imaging. OBJECTIVE To assess the accuracy and robustness of MSCT vs the criterion standard of invasive coronary angiography for detection of obstructive coronary artery disease. DESIGN, SETTING, AND PATIENTS Prospective, single-center study conducted in a referral center setting in Germ...
