Background And Purpose: Carotid intimal medial thickness (IMT) is a measure of subclinical atherosclerosis and is predictive of future cardiovascular events. The purpose of this study was to determine the significance and magnitude of association between IMT and atherosclerotic calcification of the carotid arteries.

Methods: Forty-five subjects underwent electron beam computed tomography of the neck to ascertain the extent of atherosclerotic calcification in the carotid arteries followed by B-mode carotid ultrasonography for IMT.

Background: Chronic elevation of low-density lipoprotein cholesterol is a major risk factor for developing atherosclerosis. The purpose of this study was to examine the correlation and predictive power of low-density lipoprotein cholesterol for calcified atheromatous disease as measured by electron beam computed tomography.

Methods: Six-thousand and ninety-three subjects underwent electron beam computed tomography of their coronary arteries, serum lipid testing, body fat determination and assessment of health status by questionnaire.

A 76-year-old woman with primary polycythemia vera had emboli to both superficial femoral arteries and to a branch of the superior mesenteric artery. Polycythemia vera is a neoplastic disease of bone marrow stem cells in which increased red cell production leads to hyperviscosity manifested by propensity to thromboembolic phenomena. These problems usually occur in smaller vessels, sparing large vessels that have high blood flow.

A method to localize A-V fistulas is described herein, using sterile staples as makers with angiography. This may decrease the operative time spent searching for A-V fistulas and may diminish morbidity and help improve the patency of the graft.

Ten cases of aortocaval fistula (ACF) associated with abdominal aortic aneurysm (AAA) were reviewed. In 5 cases the ACF became apparent after evacuation of the thrombus; only 5 patients presented with features of patent ACF. Four patients in addition presented with extra-caval rupture of the aneurysm.

In an attempt to identify factors contributing to survival of free fall and impact, we evaluated the records of four patients who survived a jump from the Brooklyn Bridge into the East River in New York Harbor between 1977 and 1985. All four patients were male and ranged in age from 22 to 67 years. They had free falls of between 41.

The microcirculatory correlator probe has been used on multiple occasions on the abdominal viscera and clear pulse-wave tracings have been obtained from all the intra-abdominal organs. There is a linear correlation between deflection of pulse-wave and intestine blood flow in an isolated loop of intestine under low flow conditions. The probe has been used in two circumstances to good clinical advantage.

Histopathologic changes were described and correlated with hemodynamic changes in a series of farm-reared dogs by a preparation and a protocol which were shown to simulate closely physiologic events in clinical hemorrhagic shock; neither anesthesia nor thoracotomy was used and flush solutions for catheters were strictly limited; a series of sham-treated controls was used for comparison. Five different isotopes were used to label microspheres to measure blood flow sequentially at the tissue level at various stages of the shock protocol. At death, multiple tissue sections were taken relative to six parallel segments of the lung arranged according to dependency so that correlations of structure and function might be related to the influence of gravity.
