A young woman with an occluded middle cerebral artery presented with a ruptured flow aneurysm distal on a Heubner artery as part of a moyamoya collateral network. Leptomeningeal collateral supply was tested by occlusion of the A1 origin of the Heubner artery. This test occlusion demonstrated ample collateral leptomeningeal supply over the hemispheres to the M2.

Flow diverter devices became available in our department in 2009. We considered treatment with flow diverters only in patients with aneurysms not suitable for surgery or conventional endovascular techniques. This paper presents our preliminary experience with flow diverters in a consecutive series of 550 endovascular aneurysm treatments.

Three patients are described with unruptured large partially thrombosed aneurysms with a peculiar donut-shaped remaining lumen. Observations suggest that the flow geometry of the aneurysm and parent vessels induces a preferential circular laminar flow inside the aneurysm followed by partial intraluminal thrombosis leaving a donut-shaped lumen to accommodate the circular flow. This flow mechanism of thrombus formation inside aneurysms is different from the more common repeated intramural dissections and hemorrhages that cause growth in most large and giant partially thrombosed aneurysms.

Infective endocarditis is a serious heart disease that can affect native and prosthetic valves. Staphylococci and Streptococci are the etiological agents in almost 80% of cases. Human brucellosis is a multiple organ disease often transmitted via contaminated, unpasteurized goat milk and cheese.

Adjunctive use of abciximab during percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) improves clinical outcome. This study addresses the outcome of patients with AMI treated with abciximab, initiated either before transport to a PCI center (early group) or immediately upon arrival at the catheterization laboratory (late group) for primary PCI. Of 446 consecutive patients with AMI, angiographic data and clinical complications were evaluated up to 6 months after primary PCI.
