In the past 7 years, we have encountered six patients with finger ischemia as a result of digital artery occlusion associated with seven distal ulnar artery aneurysms. Our experience with the management of these patients forms the basis of this report. All patients were men, with a mean age of 29 years, and all experienced repetitive trauma to the involved upper extremity. Each patient presente...

Aneurysms presenting as third ventricular masses are uncommon; most are giant aneurysms arising from the basilar apex. We present a case of a thrombosed basilar apex aneurysm presenting as a third ventricular mass and hydrocephalus in a 55-year-old man. The case is unique in the literature as the aneurysm was completely thrombosed and angiographically occult. The lesion was explored to verify t...

Ten years after experiencing an anterior myocardial infarction, a 71-year-old man underwent cardiac magnetic resonance imaging in the workup for placement of an implantable automatic defibrillator. A large anteroapical aneurysm was observed in the cine sequences (Figures 1A and B), and the signal difference between the tissue covering the aneurysm and the myocardium indicated extensive ventricu...

BACKGROUND The role of local alterations in endothelial functional integrity in atherosclerosis remains incompletely understood. This study used nanoparticle-enhanced optical molecular imaging to probe in vivo mechanisms involving impaired endothelial barrier function in experimental atherothrombosis. METHODS AND RESULTS Atherosclerosis was induced in rabbits (n=31) using aortic balloon injur...

This study was designed to further assess the capabilities of MR as a tool for the diagnostic evaluation of patients with giant intracranial aneurysms, to determine MR's ability to define the degree of thrombosis present within giant aneurysms before and after treatment with balloon occlusion, and to delineate the MR characteristics of both spontaneous and induced thrombus within giant aneurysm...
