Fig. 1. Preoperative images. (a) Chest X-ray. (b) Pulmonary scan with Tc-99mMAA shows absence of right lung perfusion. (c) CT image with intravenous contrast shows obstructed right pulmonary artery due to pseudo-aneurysm behind a prosthetic graft that had been implanted 23 years earlier for acute aortic dissection. These findings were accompanied by elevated D-dimer (38.2 mcg dl ) and dyspnoea ...

Pins and wires offer the simplest and most effective tools for managing bone fractures and dislocations. Migration of these devices within the chest is rare, but can cause serious problems. The spontaneous migration of Kirschner wires from the right clavicle to the mediastinum resulted in penetrating injury of the esophagus and pseudo-aneurysm of the brachiocephalic artery in an 84-year-old pat...

BACKGROUND Ascending aortic dissection (AAD) is a rare and serious complication of aortic valve replacement. Multiple risk factors such as connective tissue disease, aortic wall thinning, aortic diameter, calcification of wall, structural features of aortic wall and associated diseases have been considered as a predisposing factor for the occurrences of AAD. Preoperative recognition of these va...

INTRODUCTION Mycotic aneurysms account for a small proportion of all aneurysms. Escherichia coli a gram-negative organism, is recognised as a rare cause of aortic aneurysm. We report two cases of mycotic aneurysm caused by the same strain of multi-resistant Escherichia coli. The purpose of this case report is to highlight the possibility that this strain may be associated with an increased risk...

mycotic aneurysm is an uncommon but very important complication of subacute infectious endocarditis. it is usually asymptomatic but often causes sudden and massive bleeding with high mortality rate. 99mtc-rbc scan is a noninvasive method for detection of mycotic aneurysm throughout the body. in this report two cases with mycotic aneurysm are presented and the usefulness of 99mtc-rbc scan in dia...

Mycotic aneurysm is an uncommon but very important complication of subacute infectious endocarditis. It is usually asymptomatic but often causes sudden and massive bleeding with high mortality rate. 99mTc-RBC scan is a noninvasive method for detection of mycotic aneurysm throughout the body. In this report two cases with mycotic aneurysm are presented and the usefulness of 99mTc-RBC scan ...

the aim of this paper is to generalize the‎‎notion of pseudo-almost valuation domains to arbitrary‎ ‎commutative rings‎. ‎it is shown that the classes of chained rings‎ ‎and pseudo-valuation rings are properly contained in the class of‎ ‎pseudo-almost valuation rings; also the class of pseudo-almost‎ ‎valuation rings is properly contained in the class of quasi-local‎ ‎rings with linearly ordere...

aortoenteric fistula is a rare but significant clinical entity associated with high morbidity and mortality if remain untreated. clinical presentation and imaging findings may be subtle and prompt diagnosis can be difficult. herein, we present a patient who initially presented with abdominal pain and computed tomography showed an aortic aneurysm compressing duodenum without any air bubbles. one...
