INTRODUCTION Hemodynamic resuscitation should be aimed at achieving not only adequate cardiac output but also sufficient mean arterial pressure (MAP) to guarantee adequate tissue perfusion pressure. Since the arterial pressure response to volume expansion (VE) depends on arterial tone, knowing whether a patient is preload-dependent provides only a partial solution to the problem. The objective ...

Gastric stasis is common in rabbits, and gastrotomy may be performed to cure this pathological condition. Detailed descriptions of the arterial supply to the stomach are essential for this surgical operation, but published descriptions are limited. Here, we investigated anatomical variations of the arterial supply to the stomach in 43 New Zealand White rabbits by injecting colored latex into ar...

m n E LUID MANAGEMENT AND OPTIMIZATION are daily problems in anesthesiology and in the critical care setting. emodynamic management is related to the optimization of xygen delivery to the tissues and has been shown to be able to mprove postoperative outcome and to decrease the cost of urgery.1-7 Schematically, in the operating room, the anestheiologist and his/her patients have to deal with 2 d...

OBJECTIVES This study compared the clinical implications of quantifying myocardial perfusion among different potential arterial input sites: the high (HAo) and basal (BAo) ascending aorta, descending aorta (DA), left atrium (LA), and left ventricular (LV) cavity. BACKGROUND Absolute myocardial perfusion and its hyperemic reserve imaged by positron emission tomography (PET) can serve as noninv...

OBJECTIVES Genome wide association studies have consistently reported associations between a region on chromosome 9p21.3 and a broad range of vascular diseases, such as coronary artery disease (CAD), aortic and intracranial aneurysms and type-2 diabetes (T2D). However, clear associations with intermediate phenotypes have not been described so far. To shed light on a possible influence of this c...

The arteries supplying the upperlimb exhibit lots of variations. The present study was conducted on 102 upper limbs of 51 Nepalese bodies ( 30 males and 21 females). The objective was to find out the variations, if any in prevailing branching pattern of arteries in upper limb of Nepalese population. Arterial variation at axillary, arm, forearm and palmar level had been noted. Various types of v...

Peer-reviewed evidence (Class IIa, Level B) suggests that arterial blood temperature should be limited to 37 degrees C during cardiopulmonary bypass. We implemented a regional quality improvement initiative to reduce regional variability in our performance around this recommendation at four northern New England medical centers between January 2006 and June 2010. Cardiovascular perfusionists at ...

Introduction: Automatic arterial input function (AIF) selection has an essential role in quantification of cerebral perfusion parameters. The purpose of this study is to develop an optimal automatic method for AIF determination in dynamic susceptibility contrast magnetic resonance imaging (DSC-MRI) of glioma brain tumors by using a new preprocessing method.Material and Methods: For this study, ...
