[Roentgenosurgical diagnosis of ascending aortic arch aneurysm].

Modern invasive methods for the diagnosis of aneurism of ascending aorta and aortic arc including left ventricular angiography, aortography, and coronarography are compared with non-invasive techniques, such as transthoracal/transeosophagal echocardiography (TTE/TEE), spiral computed tomography (SCT), and magneto-resonance tomography (MRT).

[X-ray endovascular dilatation of coronary arteries in patients with unstable angina pectoris].

The outcomes of X-ray endovascular dilatation of coronary arteries in 46 patients with unstable angina pectoris are presented. Angioplasty proved to be angiographical-ly effective in 15 cases, anginal episodes ceased in 13. In 5 patients, successful dilatation was accompanied by coronary intimal dissection, as evidenced by angiography; however, its clinical effect was good.

[Diagnosis of restenosis of the coronary artery following x-ray endovascular dilatation].

Altogether 40 patients with stable angina of effort were investigated in a long-term period after roentgenovascular dilatation of one or two coronary arteries. Control coronography was performed in 22 patients with lowered exercise tolerance. A reliable feature in the development of hemodynamically significant restenosis and/or "new" coronary stenosis in 11 patients was a combination of average and low exercise tolerance with its negative dynamics.

[Diagnosis of coronary artery restenosis after radiologic endovascular dilatation].

Altogether 40 patients with stable angina of effort were investigated in a long-term period after roentgenovascular dilatation of one or two coronary arteries. Control coronarography was performed in 22 patients with lowered exercise tolerance. A reliable feature in the development of hemodynamically significant restenosis and/or "new" coronary stenosis in 11 patients was a combination of average and low exercise tolerance with its negative dynamics.

[Translumbar carotid arteriography].

On the basis of the results of examination of 27 patients with concurrent lesions of the great arteries of the arch of the aorta, the abdominal aorta, and the terminal aorta as well as arteries of the lower limbs, the authors elaborated a method of aorto-arteriography of the channels by means of a translumbar approach.
