Dunbar syndrome is caused by the compression of celiac artery median arcuate ligament (MAL) and diaphragmatic crura, presenting with abdominal pain. The treatment surgical, aim dissecting separating crura from axis, restoring blood flow in trunk. We propose use transesophageal echocardiography to measure peak systolic velocity trunk evaluate, real time, efficacy surgery during MAL resection. Tw...

Background: The nutcracker syndrome represents a clinical condition caused by compression of the left renal vein (LRV) between the superior mesenteric artery (SMA) and the aorta. One of its manifestations is left-sided varicocele. The aim of this study is to determine the prevalence of nutcracker syndrome in patients with primary and recurrent high grade left-sided varicocele. Methods: Fifty pa...

BACKGROUND Despite successful repair, patients with coarctation of the aorta (COA) often show persistent hypertension at rest and/or during exercise. Previous studies indicated that the hypertension is mainly due to abnormalities in the arterial bed and its regulatory systems. We hypothesized that ventricular systolic stiffness also contributes to the hypertensive state in these patients in add...

Today’s technological growth in the semiconductor industry has created unprecedented demand for electronic gadgets that are very sophisticated and user friendly. Interfaces with audio/video capabilities have further enhanced the demand for the products in the market. Video data needs to be compressed before storage and transmission; complex algorithms are required to eliminate the redundancy, e...

percutaneous vertebroplasty is a promising therapeutic technique for pain control in patients with pathologic fractures of vertebral bodies. percutaneous vertebroplasty is an appropriate treatment for vertebral pathologic fractures, which is resistant to other usual treatment. it is a useful and only choice in special cases, because of less tissue damage and there is no risk of open surgery and...

PURPOSE To analyze the characteristics of normal cerebrospinal fluid (CSF) flow waveforms and to relate them to the arterial input and venous output flow waveforms in healthy volunteers. METHODS Cine phase-contrast MR was obtained in 17 volunteers. The temporal velocity information from the cervical pericord CSF spaces, basal cisterns, and aqueduct, as well as the internal carotid and vertebr...

Wavelet transforms have proven to be useful tools for several applications, including signal analysis, signal coding, and image compression. This paper surveys the VLSI architec-tures that have been proposed for computing the Discrete and Continuous Wavelet Transforms for 1-D and 2-D signals. The proposed architectures range from SIMD arrays to folded architectures such as systolic arrays and p...

OBJECTIVE To examine whether use of the active compression-decompression device improves the haemodynamics of cardiopulmonary resuscitation compared with those of conventional cardiopulmonary resuscitation. DESIGN Prospective crossover study. SETTING The accident and emergency department of a university teaching hospital. PATIENTS 36 adult patients with non-traumatic, normothermic, out of...

AIMS The neurovascular pulsatile compression of the rostral ventrolateral medulla can be divided into different subtypes. The posterior inferior cerebellar artery and/or vertebral artery can compress either the rostral ventrolateral medulla or the cranial nerves IX and X or both and on left, right or both sides. METHODS It was retrospectively investigated whether the types of neurovascular co...

OBJECTIVES We sought to examine the association between systolic compression of sections of epicardial coronary vessels (myocardial bridging) with myocardial perfusion abnormalities and clinical outcome in children with hypertrophic cardiomyopathy (HCM). BACKGROUND It has recently been suggested that myocardial bridging is an important cause of myocardial ischemia and sudden death in children...
