Giant serpentine aneurysms are fusiform partially thrombosed aneurysms with a separate outflow tract to normal distal cerebral vessels. Three patients with giant serpentine aneurysms of the anterior and middle cerebral arteries were treated with endovascular occlusion of the aneurysmal lumen with coils or glue after balloon test occlusion of the involved vessel. In all 3 patients, leptomeningea...

A technique for safe angioplasty of atherosclerotic stenosis of internal and common carotid arteries is described in which temporary balloon occlusion of the internal carotid artery is used to prevent cerebral embolization during manifestation of ulcerated plaques. Its successful use in six atherosclerotic stenosis is described. Five angioplasties of postsurgical stenoses are also reported in w...

BACKGROUND Stent placement in saphenous vein bypass grafts is associated with a high incidence of myonecrosis usually resulting from embolization of thrombus and friable atheroma. Embolic protection devices reduce the incidence of adverse events after vein graft stenting. However, first-generation balloon occlusion systems are still associated with a 10% incidence of periprocedural adverse even...

Cryoballoon ablation (CBA) has been widely accepted as a major technic for pulmonary vein isolation (PVI) in patients with atrial fibrillation (AF). PV anatomy is an important factor to obtain circumferential balloon adhesion that results occlusion achieve acute PVI. The KODEX-EPD (Philips, Amsterdam, Netherlands) dielectric-based electroanatomic mapping system can display panoramic (PANO) view...

OBJECTIVE Plaque disruption does not always result in complete thrombotic occlusion. The mechanism of arterial thrombus propagation remains unclear. METHODS AND RESULTS We studied how vascular wall thrombogenicity and blood flow reduction affect thrombus propagation using a rabbit model of single and repeated balloon injury. After balloon injury of the normal femoral artery, the blood flow wa...
