Background—The purpose of this investigation was to determine optimal patient and target-vessel characteristics to maximize arterial and venous graft patency on the basis of data from a large clinical trial. Methods and Results—Angiographic data on 440 radial artery grafts and 440 saphenous vein grafts were analyzed with methodology to account for within-patient clustering. Multivariable models...

BACKGROUND AND PURPOSE Peripheral intracranial aneurysms can be difficult to treat with traditional surgical or embolization techniques that spare the parent vessel. We report the results of our use of coil occlusion of the parent vessel for the treatment of nine peripheral intracranial aneurysms. METHODS During approximately a 4-year period, nine patients (six men and three women, 27 to 68 y...

BACKGROUND Rapid restoration of vessel patency after acute myocardial infarction is key to reducing myocardial muscle death and increases survival rates. Standard therapies include thrombolysis and direct PTCA. Alternative or adjunctive emergency therapies that could be initiated by minimally trained personnel in the field are of potential clinical benefit. This paper evaluates a method of acce...

BACKGROUND Endosaccular coiling, vessel occlusion, stenting, stent-assisted coiling, and flow diversion are all endovascular treatment options for pseudoaneurysms (PAs) of the head and neck. We explore different clinical situations in which these were selected for PA management at a single institution. METHODS Over a period of ten years, 33 patients presented to our hospital with PAs of the h...

did not meet the criteria: this point was detailed in the fifth paragraph of the discussion. According to our criteria it is not true that after exclusion of 6 patients with associated infarcts, 7 of the 10 remaining subjects fulfilled criteria for small-vessel occlusion: none of these 10 did. Only 1 patient (of 16) met criteria for small vessel-occlusion in our study, this patient had an assoc...
