Severe carotid stenosis or occlusion may cause insufficient blood flow and lead to distal artery wall collapse and extensive lumen contraction. Whether this 'adaptive narrowing' can restitute after carotid recanalization is unclear. We report a patient with global ischemia due to occlusions of bilateral carotid and right vertebral arteries. The occluded left carotid was recanalized successfully...

BACKGROUND We report the occurrence of fatal intracerebral hemorrhage associated with using a combination of antithrombotic agents, including abciximab, in patients undergoing neurointerventional procedures. SUMMARY OF REPORT Seven patients (average age 60, range 46 to 73 years) developed fatal intracerebral hemorrhages associated with neurointerventional procedures and the use of intravenous...

Vascular neointimal hyperplasia and remodeling arising from local inflammation are characteristic pathogeneses of proliferative cardiovascular diseases, such as atherosclerosis and post angioplasty restenosis. The molecular mechanisms behind these pathological processes have not been fully determined. The adipokine chemerin is associated with obesity, metabolism, and control of inflammation. Re...

Atherosclerotic carotid stenosis is responsible for 10% of ischaemic strokes but until recently there has been uncertainty about the benefit of treating carotid stenosis. However, two randomised controlled trials, the North American Symptomatic Carotid Endarterectomy Trial (NASCET)l and the European Carotid Surgery Trial (ECST),' have now convincingly established the benefit of carotid endarter...

We present 2 cases of complicated mechanical thrombectomy involving tandem cervical internal carotid artery and middle cerebral artery occlusion using the Solitaire FR stent and simultaneous carotid stent angioplasty. During the procedures, the Solitaire stents containing the thrombus were wedged into the open-cell carotid stents, which were already deployed for proximal flow restoration. We de...

Distal embolization resulting from carotid angioplasty and stenting (CAS) occurs mainly in the cerebral hemisphere. We report a case of ophthalmic artery occlusion after carotid revascularization. A 75-year old man received emergency CAS for cervical internal carotid artery occlusion. Two months later, the patient was readmitted for decreased visual acuity. We found ophthalmic artery occlusion ...

A 57-year-old male presented with right amaurosis fugax and left transient ischemic attack caused by stenosis of the intracranial segment of the right internal carotid artery (ICA). Percutaneous transluminal angioplasty with stenting was successfully performed to dilate the stenosis. However, serial angiography revealed the development of a large pseudoaneurysm in the cervical ICA, probably as ...
