Angiography Findings (angiography + finding)
Selected AbstractsContrast-enhanced power Doppler sonography of ductal pancreatic adenocarcinomas: Correlation with digital subtraction angiography findingsJOURNAL OF CLINICAL ULTRASOUND, Issue 4 2004Chien-Hua Chen MD Abstract Purpose The purpose of this prospective study was to utilize contrast-enhanced power Doppler sonography to evaluate the enhancement characteristics of ductal pancreatic adenocarcinomas and correlate them with the tumor vascularity observed on digital subtraction angiography (DSA). Methods Twenty consecutive patients with ductal pancreatic adenocarcinoma underwent power Doppler sonography and DSA. Tumor vascularity was assessed using unenhanced and contrast-enhanced power Doppler sonography. The contrast agent Levovist was administered intravenously by bolus injection of a dose of 2.5 g at a concentration of 350 mg/mL; saline was administered immediately thereafter. The patients were asked to hold their breath for 30 seconds (for the period 15,45 seconds after saline injection) while the early phase of enhancement was studied; the delayed phase of enhancement was observed between 60 and 120 seconds after saline administration, while patients breathed gently. Results None of the 20 pancreatic carcinomas showed any color signals on power Doppler sonography before administration of the contrast medium. Seventeen (85%) of the 20 pancreatic carcinomas also showed no enhancement in the early and delayed phases of contrast-enhanced power Doppler sonography. However, in the early phase of contrast-enhanced power Doppler sonography; 1 lesion showed pronounced enhancement and 2 showed mild enhancement. On DSA, the 17 carcinomas showing no enhancement on power Doppler sonography were found to be hypovascular, whereas the remaining 3 carcinomas with contrast enhancement on power Doppler sonography were found to be hypervascular. Conclusions The enhancement characteristics of the ductal pancreatic adenocarcinomas correlated well with the tumor vascularity observed on DSA. However, further study is needed to determine the accuracy of contrast-enhanced sonography in the diagnosis of pancreatic masses. © 2004 Wiley Periodicals, Inc.

We describe a penile Mondor's disease (penile superficial dorsal vein thrombosis) of uncertain pathogenesis involving the penile superficial vein, and employing a careful diagnostic pathway by using magnetic resonance angiography (MRA). In the literature many reports described pulsed- and color-Doppler ultrasonography classical findings about penile Mondor's disease. For the first time we report the pathognomonic features of penile Mondor's disease on MRA, which may be considered a useful and comprehensive tool to deepen the analysis only in the case of a complex clinical picture such as the one presented.

Jabaudon Summary A 77-year-old female was admitted in our hospital for uterine prolapse surgery. She developed ventricular tachycardia during induction of general anaesthesia and after initial symptomatic measures, she was transferred to the coronary care unit. Heart failure persisted and electrocardiographic changes mimicking acute myocardial infarction appeared. Coronary angiography was normal and left ventriculography revealed akinesis of the apical region of the left ventricle and apical ballooning during systole, with relative sparing of the base of the heart. Complete recovery of left ventricular function occurred 8 days after the initial onset of symptoms. A diagnosis of Takotsubo syndrome was made on the basis of consistent clinical and laboratory findings, typical echocardiography and angiography findings, and reversible course. This case emphasises the importance of being aware of uncommon causes of cardiac dysfunction in stressful situations, especially during induction of general anaesthesia.

Methods: We investigated 101 patients with a diagnosis of anterior AMI with or without ST-segment elevation or ST-segment depression in at least two leads in Dll, III, aVF. The patients were classified as those with vessel involvement in the left anterior descending (LAD) coronary artery and patients with multivessel disease. Vessel involvement in LAD + circumflex artery (Cx) or LAD + right coronary artery (RCA) or LAD + Cx + RCA were considered as multivessel disease. Thus, (a) anterior AMI patients with reciprocal changes in inferior leads, (b) anterior AMI patients with inferior elevations, (c) all anterior AMI patients according to the ST-segment changes in the inferior region were analyzed according to the presence of LAD or multivesssel involvement. Results: Presence of ST-segment depression in aVL and V6 was significantly correlated with the presence of multivessel disease in anterior AMI patients with reciprocal changes in the inferior leads (P = 0.005 and P = 0.003, respectively). No statistically significant difference between the leads were detected in terms of ST-segment elevation in predicting vessel involvement in the two groups of anterior AMI patients with inferior elevations. When all the patients with anterior AMI were analyzed, the presence of ST-segment depression in leads aVL, V4, V5 and V6 were significantly associated with the presence of multivessel disease (P = 0.035, P = 0.010, P = 0.011, P = 0.001, respectively). Conclusions: The presence of ST-segment depression in anterolateral leads in the admission ECG of anterior AMI patients with reciprocal changes in inferior leads was associated with multivessel disease.
