BACKGROUND Carotid artery stenting (CAS) is a reasonable alternative to carotid endarterectomy (CEA), especially in patients at high risk for surgery. Carotid artery thrombosis of the treated segment is a rare, early but potentially devastating complication of this endovascular procedure. The aim of this article is to identify and critically review cases of acute stent thrombosis reported in th...

Thrombosis of the internal carotid artery with neurological signs may develop after direct violence to the wall of the artery in the neck. This has been known at least as far back as the last century and calls for little comment. A description of two such cases was published in 1936 by Caldwell, who warns against the error of attributing to concomitant head injury the symptoms and signs which d...

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...

Giant intra and parasellar aneurysm with a spontaneous thrombosis of internal carotid artery is rare. We report the case of a 34 years old woman presenting a unique giant sellar and parasellar aneurysm associated with hypopituitarism and amenorrhea-galactorrhea syndrome. Computed tomographic scans and magnetic resonance images were suggestive of a sellar tumor with a cystic component. Digital c...

variation of the branches of the external carotid artery (eca) is well known, but it is extremely rare for the occipital artery (oa) to arise from the internal carotid artery (ica). a 87-year-old man was found to have this anatomical variation on the right side by threedimensional computed tomography angiography for vascular mapping of the carotid arteries before superselective intra-arterial c...

Although spontaneous thrombosis of a giant intracranial aneurysm is relatively common, occlusion of its parent artery is rare. We describe two recent patients in whom the parent artery spontaneously occluded. One patient had severe stenosis of the left internal carotid artery, with delayed appearance of a faint shadow of vascular widening near the posterior clinoid process. One month later, com...

In carotid artery stenting (CAS) procedures, distal embolism, periprocedural stent thrombosis, and 30-day stroke due to the plaque fragmentation and protrusion caused by stent implantation and balloon dilation are frequent complications. In this technical case report, a case is presented of extracranial carotid artery stenosis treated with a covered stent and subsequent implantation of a bare s...

BACKGROUND AND PURPOSE Chlamydia pneumoniae has repeatedly been associated with atherosclerotic disease. Our study was designed to clarify whether this association is based on C pneumoniae-induced transformation of a stable into an unstable atherosclerotic plaque or on stimulation of hypercoagulability leading to increased thrombotic arterial occlusions by C pneumoniae infection. Transcranial D...
