radionuclide shuntography is a safe and simple method to determine shunt patency and analyze changes in csf (cerebro-spinal-fluid) flow. we present a case of complicated csf shunt, in which radioisotopic scan correctly identified disconnection of the shunt tubing system localizing the site of extravasation accurately. the findings were confirmed by surgery performed for correction of the shunt ...

conclusions bladder perforation and stones are rare examples of complications in v-p surgical procedures. controlling the effective length of the terminal v-p shunt and modifying it appropriately can effectively reduce these complications. case presentation we report on a 38-year-old male who had hydrocephalus and v-p shunt for 12 years. two years ago, he found himself with recurrent urinary tr...

Intravenous adenosine is considered the drug of choice to obtain maximum hyperemia in the measurement of the fractional flow reserve (FFR). However, comparative studies performed between intravenous and intracoronary administration have not used high doses of intracoronary adenosine. The present study compared the efficacy and safety of high doses of intracoronary adenosine to intravenous admin...

background: intrapulmonary vascular abnormalities associated with liver cirrhosis may result in intrapulmonary right-to-left shunt and hypoxemia. the aim of this study was to use contrast enhanced echocardiography to detect intrapulmonary vascular abnormalities in patients with liver cirrhosis candidates for liver transplantation.   methods: one hundred and two adult patients underwent contrast...

The positive effect of vitamin C on left ventricular (LV) inotropic responses to dobutamine, observed in patients with preserved LV function, is lost in heart failure (HF). We tested the hypothesis that in HF, endogenous nitric oxide (NO) opposes the positive effect of vitamin C on adrenergically stimulated contractility by examining the effects of vitamin C on dobutamine responses during NO sy...

Intracoronary stents have markedly improved the outcomes of catheter-based coronary interventions. Intracoronary stent implantation rates of over 90% during coronary angioplasty are common. Stent implantations are associated with a small but statistically significant number of adverse outcomes including restenosis, thrombosis, strut malapposition, incomplete strut endothelialization, and variou...

AIMS To assess the value of videodensitometric quantification of the coronary lumen after angioplasty by comparison to two other techniques of coronary artery lumen quantification. METHODS AND RESULTS Videodensitometric quantitative angiography, edge detection quantitative angiography and 30 MHz intracoronary ultrasound imaging were performed after successful balloon angioplasty in 161 patien...

Intracoronary thrombus is regarded as a potentially important factor in the etiology of unstable angina, but the incidence of intracoronary thrombus in unstable angina has not been clearly defined. To determine the occurrence of intracoronary thrombus during ongoing angina pectoris, coronary angiography was performed during spontaneous ischemic attacks in 37 patients with prolonged rest angina....
