lar complications including thromboses of the portal venous system and the formation of a pseudoaneurysm. Pseudoaneurysms occur in approximately 3.5-10.0% of patients with pancreatitis (1). The arteries most commonly affected by pseudoaneurysms are (in decreasing percent occurrence), the splenic (40%), gastroduodenal (30%), pancreaticoduodenal (20%), gastric (5%), hepatic (2%), and others (supe...

BACKGROUND AND PURPOSE Thromboembolic events are a major cause of ischemic stroke. To obtain evidence for platelet embolization after cerebrovascular injury, the accumulation of indium-labeled platelets was documented after photothrombosis of the rat common carotid artery. METHODS Heterologous blood was collected from donor rats, and the isolated platelets were labeled with 111In-tropolone. L...

Two cases of patients with multiple peripheral aneurysms are reported ; four aneurysms arising from the left callosomarginal artery feeding an arterivenous malformation (AVM) in a 51year-old female and two aneurysms from the left posterior inferior cerebellar artery not associated with AVM in a 53-year-old female. In the former case , the AVM was partly thrombosed and the most distal aneurysm w...

Extracranial carotid artery aneurysms (ECAAs) are rare, and their treatment is very difficult and challenging. The case of a 59-year-old woman who presented with a pulsatile mass on the left side of her neck, was diagnosed with a left-sided giant thrombosed common carotid artery aneurysm, and underwent definitive treatment by overlapped stenting, is presented. Overlapped stenting is a safe and ...

True extracranial carotid artery aneurysms (ECCAs) are uncommon. Atherosclerosis is the most common etiological factor. Neck pain, a pulsatile mass and murmur at auscultation are the most common symptoms. ECCAs may exhibit severe clinical manifestations due to complications. Cases of rupture can be fatal. There is a risk of distal embolization and stroke in thrombosed cases. We discuss two case...
