STUDY DESIGN The internal architecture of cervical spine pedicles was investigated by thin sectioning and digitization of radiographic images. OBJECTIVES To provide quantitative information on the internal dimensions and cortical shell thicknesses of the middle and lower cervical pedicles. SUMMARY OF BACKGROUND DATA Although there have been a number of(More)
Transpedicular screw fixation has recently been shown to be successful in stabilizing the middle and lower cervical spine. Controversy exists, however, over its efficacy, due to the smaller size of cervical pedicles and the proximity of significant neurovascular structures to both lateral and medial cortical walls. To aid the spinal surgeon in the insertion(More)
AIMS Ramipril and candesartan have distinct mechanisms of action to improve endothelial function. Therefore, we hypothesized that combination therapy has additive beneficial effects to simultaneously improve endothelial dysfunction and adipocytokine profiles in patients with hypertension. METHODS AND RESULTS Thirty-four patients were given ramipril 10 mg(More)
STUDY DESIGN An anatomic study of cervical vertebral bodies. OBJECTIVES To provide quantitative information on the cortical shell architecture of the middle and lower cervical vertebral bodies. SUMMARY OF BACKGROUND DATA Some external dimensions have been measured, but little quantitative data exists for the cortical shell architecture of the vertebral(More)
BACKGROUND AND OBJECTIVES The purpose of the current study was to assess left atrial (LA) physiology in relation to associations between LA volume change and regional tissue velocities and strains, and to extend this information to patients with mitral stenosis (MS) or mitral regurgitation (MR). SUBJECTS AND METHODS Twenty-two healthy persons, 22 patients(More)
BACKGROUND AND OBJECTIVES We describe our experience with combined open and endovascular repair in patients who have aortic arch pathology. SUBJECTS AND METHODS This study is a retrospective analysis of 7 patients who underwent combined open and endovascular repair for aortic arch pathology. Medical records and radiographic information were reviewed. (More)
BACKGROUND AND OBJECTIVES The aim of this study was to compare the effects of a combination of niacin and simvastatin to simvastatin alone, on plaque regression and inflammatory makers. SUBJECTS AND METHODS The study had a prospective, randomized design. Subjects were patients with intermediate coronary artery stenosis. A total of 28 patients received a(More)
A 69-year-old woman diagnosed as having end-stage dilated cardiomyopathy had undergone partial left ven-triculectomy (PLV) in 1996. This is the first reported case of PLV (Batista procedure) in Korea. 1) She was doing well under the New York Heart Association class II diagnosis in November 2009 and had received 3-dimensional (3D) echocardiography for the(More)
A 1-month-old boy without precedent clinical signs of heart disease died unexpectedly. At autopsy, the child was found to have origin of the right coronary artery from the left sinus of Valsalva immediately leftward to the thickening of the aortic wall at the cuspal commissure and adjacent to the ostium of the left main coronary artery. The association of(More)
