Pulmonary saequestration is a rare congenital malformation characterized by dysplastic portion of lung parenchyma supplied an anomalous artery originating from the aorta or its branches. The worldwide incidence pulmonary sequestration among all malformations in children ranges 1.5% to 6.4%. There are two main types according localization malformation, i.e., intrapulmonary (dysplastic tissue loc...

The purpose of this educational exercise is to describe some of the salient features of the physiology of the mesenteric circulation, focusing particularly on the regulation of its blood flow. The reader is referred to several recent reviews of the subject that are more extensively referenced with original sources (5, 6, 10, 11). Although the terms “mesenteric circulation” and “splanchnic circu...

BACKGROUND Imaging of the aorta has received less attention than imaging of the coronary beds, despite the possible link between aortic and coronary artery disease (CAD). Electron beam computed tomography (EBCT) with 100 ms scanning speed can eliminate pulsation-related motion artifacts. The goals of this study were to evaluate EBCT-detected subclinical atherosclerosis over the whole aorta as i...

E-Mail: [email protected] Introduction: The anatomical variations of the Celiac trunk and its branches are due to developmental changes in the ventral splanchnic arteries. The arterial variations like other anatomical...

Giant cell arteritis is a granulomatous vasculitis characterized by medium or large sized vessel involvement. Although extracranial branches of the carotid artery are typically involved, involvement of aorta and its major branches can also be seen. Cardiac involvement has been encountered less frequently and pericardial effusion is rarely encountered. In this paper, a case has been presented in...

Objective: Despite major advances in imaging techniques, correct diagnosis of acute aortic dissection is frequently missed. Although as many as one-third of acute cases of aortic dissection involve the abdominal aorta, emergency physicians rarely suspect this lethal disease in patients presenting with abdominal pain. Transabdominal sonography is typically employed by emergency physicians, but t...

The human aorta and its terminal branches were investigated in normal subjects during elective cardiac catheterization to evaluate regional wave travel and arterial wave reflections. A specially designed catheter with six micromanometers equally spaced at 10 cm intervals was positioned with the tip sensor in the distal external iliac artery and the proximal sensor in the aortic arch. Simultaneo...
