Middle cerebral artery flow after angioplasty and stenting of symptomatic internal carotid artery stenosis.

Background And Purpose: Improved haemodynamics in the middle cerebral arteries (MCAs) after carotid artery endaterectomy (CEA) has been demonstrated in a number of studies, whereas similar analyses on carotid angioplasty and stenting (CAS) remain insignificant. The purpose of the study was to test whether CAS affects haemodynamic parameters of MCA ipsilaterally and contralaterally to the side of the procedure in patients with symptomatic internal carotid artery (ICA) stenosis, assessed by transcranial Doppler (TCD) examination.

Material And Methods: Carotid angioplasty and stenting was performed in 51 patients (39 men and 12 women) aged 45-86 (mean age: men 65.

Circulation monitoring in anterior cerebral arteries in hypertensive patients with ischemic stroke, without hemodynamically significant stenosis in extracranial arteries.

Introduction: The current project was aimed at elucidating whether blood pressure fluctuations in hypertensive patients with ischemic stroke, not characterized by hemodynamically significant stenosis in carotid arteries and proximal segments of intracranial arteries lead to circulation disturbances in anterior cerebral arteries (ACAs) as visualized by transcranial Doppler ultrasound (TCD).

Material And Methods: Sixty two hypertensive patients with the first ever ischemic stroke were included in the study with the average age of 65.16 +/- 11.

An approach of patients with ischemic stroke to primary and secondary stroke prevention in Poland.

Introduction: The stroke mortality rate in the Polish population is significantly higher than the average stroke mortality in Western Europe. It may prove a poor "initial" health condition of the Polish population which is afflicted with many life-threatening diseases which are at the same time the major risk factors for both: first ever and recurrent stroke. The aim of our study was to evaluate what is an attitude of Polish people with first-ever or recurrent stroke to keeping under control the most important risk factors for ischemic stroke.

[Intra-arterial thrombolysis for acute angiographically proven occlusion in bifurcation of basilar artery. Case report].

In a 52 year-old male patient with a past history of two strokes, an occlusion of the basilar cerebral artery in the area of bifurcation into the posterior cerebral arteries was angiographically confirmed. Following an intra-arterial application of rt-PA a partial revascularization of the occluded posterior arteries was observed. After an interval of 8 hours rt-PA was administered again, resulting in a complete recanalization of the arteries.
