Analysis of the Impact of Invisible Road Icing on Selected Parameters of a Minibus Vehicle.

The measurement of acceleration during vehicle motion can be used to assess the driving styles and behaviours of drivers, to control vehicle traffic, to detect uncontrolled vehicle behaviour, and to prevent accidents. The measurement of acceleration during vehicle motion on an icy road can be used to warn the driver about changing conditions and the related hazards. This paper presents the results of testing the motion parameters of a Ford Transit adapted for passenger transport in critical traffic conditions.

Research and Analysis of the Propagation of Vertical Vibrations in the Arrangement of a Vehicle Seat-A Child's Seat.

This paper deals with the issues of the impact of vertical vibrations on a child seated in a child seat during a journey. Its purpose was to assess the impact of fastening the child seats and road conditions on the level of vibrations recorded on child seats. The paper describes the tested child seats, the methodology of the tests and the test apparatus included in the measuring track.

Percutaneous transluminal angioplasty for treatment of subclavian steal.

Twenty-two patients with subclavian steal were treated with percutaneous transluminal angioplasty (PTA). Fifteen had unilateral stenosis of the subclavian artery, one had severe stenosis on the left and total occlusion on the right, five had total subclavian occlusion on the left, and one had total occlusion of the innominate artery. All subclavian stenoses as well as the occluded innominate artery were successfully dilated, resulting in correction of subclavian steal; however, attempts to recanalize the totally occluded subclavian arteries failed.

Percutaneous transluminal angioplasty of the brachiocephalic arteries.

Percutaneous transluminal angioplasty was used to treat atherosclerotic lesions in 22 brachiocephalic arteries in 20 patients during a 2 1/2 year period. Seven subclavian, 13 vertebral, one external carotid, and one common carotid arteries were involved. Nineteen arteries were successfully dilated, but dilatation of two vertebral arteries and attempted recanalization of one subclavian artery failed.

Percutaneous transluminal angioplasty as a complement to surgery.

Transluminal angioplasty, a nonsurgical treatment for atherosclerotic occlusive disease, was performed on 56 arteries in 45 patients in conjunction with reconstructive vascular surgery. Twelve patients were treated presurgically, 12 patients were treated postsurgically, and 21 patients were treated intraoperatively. Some arteries were dilated to increase arterial inflow to the graft or to improve the distal runoff.

Percutaneous transluminal angioplasty of the vertebral arteries.

Dilatation of stenosis at the origin of the vertebral artery, using a Grüntzig balloon catheter, was attempted in 5 selected patients and was successful in 4. Two patients had isolated vertebral artery disease without significant carotid occlusive disease, while the other 3 also had ulcerated carotid plaques. All patients had classical vertebral basilar insufficiency and were being considered for reconstructive surgery; however, dilatation alleviated the symptoms and made surgery unnecessary.

Percutaneous transluminal angioplasty of the iliac arteries: 66 experiences.

Sixty-six iliac arteries in 45 patients, 25 male and 20 female, were treated with percutaneous transluminal angioplasty (PTA) for atherosclerotic occlusive disease. Of 103 lesions dilated, 51 were in common iliac and 51 in external iliac arteries. While iliac artery disease was the primary lesion in 18 patients, eight of whom had total occlusion, 27 patients had additional femoropopliteal disease.

Percutaneous transluminal angioplasty of the deep femoral artery.

Successful dilatation and recanalization of the severely stenotic or completely occluded deep femoral arteries in twelve patients is presented. This nonsurgical procedure is effective, less traumatic, and less time-consuming than surgical endarterectomy.

Percutaneous transluminal angioplasty and case selection.

The application of percutaneous transluminal angioplasty (PTA) in the treatment of arteriosclerotic occlusive disease is relatively new in the United States. To ascertain more data on case selection, procedure, and success rate, the authors evaluated 100 consecutive patients as possible candidates for treatment with PTA. Patients were divided into five groups on the basis of procedural acceptability.
