Venous thrombosis is relatively under-diagnosed condition with a potential for significant morbidity and mortality. It is under-diagnosed because in many individuals it may be asymptomatic and the signs and symptoms when present are non-specific. Most episodes of venous thrombosis occur in the deep veins of lower limbs, though venous thrombosis is known to occur at other sites. The morbidity in...

OBJECTIVE We wanted to assess the usefulness of rotational angiography after endoscopic marking with a metallic clip in upper gastrointestinal bleeding patients with no extravasation of contrast medium on conventional angiography. MATERIALS AND METHODS In 16 patients (mean age, 59.4 years) with acute bleeding ulcers (13 gastric ulcers, 2 duodenal ulcers, 1 malignant ulcer), a metallic clip wa...

TOPIC: Imaging TYPE: Medical Student/Resident Case Reports INTRODUCTION: Patients with intravenous drug use are at risk for the development of air aneurysm through introduction air. In this report, we present a patient use-induced venous embolism without cerebral who had non-operative spontaneous resolution and was ultimately safely discharged home. CASE PRESENTATION: A 35-year-male ongoing ill...

Objective This study aims to define risk factors as well as their association with microbiology and clinical outcomes in a large US infective endocarditis population. Methods Hospital records were searched for appropriate infective endocarditis-related ICD codes from 16 July 2007 to 13 August 2015. A total of 363 cases were retrospectively identified that met definite Modified Duke Criteria f...

species competition. Perhaps the best example is Robert Ardrey’s “The Territorial Imperative.” We’re all familiar with images of the African watering hole surrounded by collections of various animal species mingling in defined patterns and demonstrating respect for the dominant animals. Once away from the watering hole, they only mix with their own species and an intra-species turf structure em...

The development of pulmonary metastases after local surgical control of malignant tumors has represented a major cause of treatment failure in a variety of neoplasms. The metastatic process has been a subject of considerable interest, investigation, and speculation for many years, but it remains as a poorly characterized and little understood phenomenon. The formation of blood-borne metastases ...

BACKGROUND Half of all lower limb deep vein thrombi (DVT) in symptomatic ambulatory patients are located in the distal (calf) veins. While proximal disease warrants therapeutic anticoagulation to reduce the associated risks, distal DVT often goes untreated. However, a proportion of untreated distal disease will undoubtedly propagate or embolize. Concern also exists that untreated disease could ...

Fetal hypoxaemia may result from altered maternal PaO2 or a reduction in maternal placental or umbilical blood flow. It is also possible that reduction of gas exchange across the placenta could limit the oxygen supply to the fetus. In this review we will be concerned with the effects of hypoxaemia in fetal sheep during the latter half of pregnancy. At present it is not easy to reduce maternal p...

BACKGROUND AND PURPOSE We sought to describe the clinical outcome and angiographic results obtained in the endovascular therapy of ruptured posterior circulation cerebral aneurysms using Guglielmi detachable coils (GDC) over a 7-year period. METHODS A retrospective analysis was performed of 112 patients evaluated at the University of California at San Francisco Medical Center between June 199...

When significant thoracic vascular anomalies occur in children, they may present surgical difficulties making operative management undesirable. The recent development of a new, accurate coil-delivery system has enabled us to embolize 17 vessels in five children by passing Gianturco steel coils coated with thrombogenic Dacron strands through No. 5 or 6F end-hole catheters suitable for infants. C...
