Wound healing after angioplasty or stenting is associated with increased production of thrombin and the activation of protease-activated receptor 1 (PAR1). The aim of the present study was to examine the effects of a new selective PAR1 antagonist, 2-[5-oxo-5-(4-pyridin-2-ylpiperazin-1-yl)-penta-1,3-dienyl]-benzonitrile (F 16618), in restenosis and vascular smooth muscle cell (SMC) proliferation...
BACKGROUND Patients with intracranial arteriosclerotic disease have significant morbidity and mortality rates, and some are unresponsive to medical treatment and have unacceptable surgical risks. Percutaneous transluminal angioplasty of the intracranial vessels is a possible alternative to surgery. OBJECTIVES To present our experience with percutaneous transluminal angioplasty and to summariz...
Involuntary movement associated with deep watershed ischemic lesions has been rarely reported. A 67-year-old woman presented with acute hemichorea on the left side. Magnetic resonance imaging showed acute infarcts in the anterior border zone. On perfusion studies, impaired cerebral blood flow was observed on the subcortical region sparing the basal ganglia. Cerebral angiogram confirmed severe s...
The number of endovascular procedures is constantly increasing. As far as the carotid artery is concerned, carotid angioplasty with stenting (CAS) is an alternative to surgical treatment (carotid endarterectomy; CEA). Two major devastating complications can occur after both procedures – cerebral hyperperfusion syndrome (CHS) and intracranial haemorrhage (ICH). The incidence of CHS and ICH in CA...
Background Patients older than 80 years old were excluded from participation in the large controlled randomized trials that demonstrated the efficacy of carotid endarterectomy (CEA) in preventing stroke in selected symptomatic and asymptomatic patients. Because of limited longevity and perceived increased perioperative risk from CEA, alternative treatment options, such as carotid angioplasty an...
Coronary-subclavian steal syndrome results from atherosclerotic disease of the proximal subclavian artery causing reversal of flow in an internal mammary artery used as conduit for coronary artery bypass. This rare complication of cardiac revascularisation leads to recurrence of myocardial ischaemia. When feasible, subclavian angioplasty and/or stent placement can provide acceptable result for ...
OBJECTIVE Open surgical treatment of carotid artery stenosis, namely, carotid endarterectomy (CEA), has evolved since its inception in 1953. Despite improvements in the treatment of carotid occlusive disease through technological and surgical innovations, the use of patch grafting in CEA's remains controversial. We evaluate the durability of the primary closure and the safety of selective shunt...
Carotid endarterectomy (CEA) is an effective treatment for patients with recently symptomatic severe carotid stenosis and in selected patients with symptomatic moderate carotid stenosis. Carotid artery angioplasty and stenting (CAS) is emerging as an alternative to CEA, and randomised controlled trials suggest comparable efficacy to CEA in prevention of non-perioperative stroke. Neurovascular c...
