Diagnostic accuracy of Doppler sonography and magnetic resonance venography for the assessmentv of impaired outflow from the internal jugular vein in…

2015

Objectives: This prospective study was aimed at evaluation of diagnostic value of Doppler sonography and magnetic resonance (MR) venography in the internal jugular vein territory. Material and methods: There were assessed 126 patients (252 internal jugular veins). The patients were initially diagnosed using Doppler sonography and MR venography, and then catheter venography of the veins was performed. For the purpose of this study catheter venography was regarded the reference test. We interpreted sonographic findings in the context of criteria proposed by Zamboni and criteria by International Society for Neurovascular Disease (ISNVD). We applied MR protocols aimed at flow assessment in the …

Advances in detection and characterization of atherosclerosis using contrast agents targeting the macrophage

2006

With advances in imaging technology and our understanding of the role of inflammation in atherosclerosis, the macrophage appears to be an excellent target for imaging the progression of disease. In addition to imaging the macrophage with only 1 modality, contrast agents can be created that can be imaged with multiple modalities. This seems extremely attractive, as lesion morphology and characteristics can be determined with modalities that provide high picture resolution, such as CT or MRI, whereas macrophage quantity can be accurately determined through the creation of a radiolabeled contrast agent such as FDG via PET. Although this combination of imaging technologies may yield clinically …

Ethical issues: invasive ventilation in amyotrophic lateral sclerosis.

2012

The first man was a school headmaster. By his eye-gaze system he is able to order coins to enlarge his 10-year collection. His grandchildren extort presents from him in exchange for help. The second was a prefect and even now insists that the flowers in the garden represent the national flag. In spite of his gastrostomy, he still likes to sip his espresso from porcelain cups. The ventilation circuit 24/7 has not changed his custom to read the newspapers and listen to classical music in the living room. That girl is a young mum. She is fed by a tube, but she always makes her little child laugh with the dialectal phrases that she writes on the screen. The surgeon, every day in his electric wh…

Intravaskuläre Sonographie: Erste klinische Ergebnisse

1991

Intravascular ultrasound is a new diagnostic modality which, for the first time, provides high resolution images of the vessel wall. 91 intraluminal ultrasound studies were performed in 50 patients during the course of 55 diagnostic and therapeutic catheterizations. A F-6 ultrasound catheter (20 MHz) was used. The method is an easily and rapidly performed addition to angiography. Changes in vessel walls (arteriosclerosis, dissection, tumour infiltration) can be readily diagnosed and their extent can be accurately described. The ability to determine luminal cross sectional area is particularly helpful for planning and performing therapeutic interventions.

Left Renal Vein Anatomical Anomalies: Radiological and Surgical Implications

1998

Objective: To emphasize the incidence and clinical, diagnostic and surgical implications of left renal vein developmental anomalies. Design: Retrospective analysis of case notes. Setting: Clinical Anatomy Department and Surgery Department, Faculty of Medicine, University of Valencia, Spain. Patients, participants: Standard radiological examinations (CT scan) performed on 745 patients; surgical findings at operation in 128 patients with aorto-iliac atherosclerotic disease, and 72 donor cadavers for transplantation. Main outcome measures: Incidence of left renal vein anomalies (retro-aortic left renal vein and peri-aortic renal venous collar), based on radiological (CT scan) and surgical obse…

Multiple sclerosis, an unlikely cause of chronic cerebrospinal venous insufficiency: retrospective analysis of catheter venography.

2013

Objectives It is unknown if a relationship exists between multiple sclerosis and chronic cerebrospinal venous insufficiency and if this venous pathology is a causal factor for multiple sclerosis or is a product of a neurological disease. Even so, one should expect that if multiple sclerosis were the cause for venous lesions, then patients with an extended history of the disease would present with a more severe venous pathology. Design Retrospective analysis of catheter venography of the azygous and internal jugularveins, and duration of clinical history of the disease in multiple sclerosis patients. Setting Mono-profile specialist hospital. Participants 353 multiple sclerosis patients, with…

Coronary plaque imaging with multislice computed tomography: technique and clinical applications.

2006

The composition of an atherosclerotic lesion, rather than solely the degree of stenosis, is considered to be an important determinant of acute coronary events. Whereas until recently only invasive techniques have been able to provide clues about plaque composition with consistent reproducibility, several recent studies have revealed the potential of multislice computed tomography (MSCT) for noninvasive plaque imaging. Coronary MSCT has the potential to detect coronary plaques and to characterize their composition based on the X-ray attenuating features of each structure. MSCT may also reveal the total plaque burden (calcified and noncalcified components) for individual patients with coronar…

Response-based chemotherapy and involved field radiation for intermediate stage Hodgkin disease. A GISL/NHLSG trial.

2006

Abstract Background. Most of the patients with advanced stage Hodgkin lymphoma can be cured with a standard course of six cycle of ABVD chemotherapy plus involved field (IF)radiotherapy. Patients with less advanced stage or with a more responsive disease could possibly achieve a cure with a shorter course of chemotherapy. In 1992, in the pre-PET era, the GISL addressed the issue of the proper number of chemotherapy cycles planning a response-oriented, ABVD-based study for intermediate-stage Hodgkin’s lymphoma patients. Patients and Methods. From January 1992 to December 2002, 218 patients younger than 70 were enrolled. Eligible patients had histologically confirmed and clinically staged Hod…

Transdermal estrogens do not appear to modify the extent of lesional areas of aortic atherosclerosis in oophorectomized rabbits on a cholesterol-rich…

2000

Cardiovascular disease (CVD) is the leading cause of death in older women in industrialised countries. It has been suggested that it is the cessation of estrogen production by the ovaries that puts postmenopausal women at increased risk of CVD. Estrogen therapy has demonstrated a protective effect against CVD and several reports suggest that diverse mechanisms may be involved. Oral estrogen appears to be associated with a better lipid profile than the use of transdermal estrogens; however, it is assumed that estrogens, oral and non-oral, have direct actions on the blood vessels that may exert an important role in cardiovascular disease prevention. To investigate the effect of transdermal es…
