FEATURES OF FORMATION OF COLLATERAL CIRCULATION IN PATIENTS WITH SUBCLAVIAN STEAL SYNDROME.

To date in patients with subclavian steal syndrome diagnosis is only grade of stenosis or localization of occlusion described. Authors recommend to take into account also type of a collateral compensation of cerebral circulation for selection of an optimal treatment The objective of the research was to study the features of formation of collateral circulation in patients with subclavian steal syndrome. The authors described changes in the direction of blood flow in the extracranial vessels of 42 patients with subclavian steal syndrome.

[FUNCTIONAL STATE OF PERIPHERAL VESSELS OF THE LOWER EXTREMITIES AND INTRAOSSEOUS PRESSURE IN PATIENTS, SUFFERING OBLITERATING ATHEROSCLEROSIS ON BACKGROUND OF DIABETES MELLITUS].

Results of examination of 46 patients, suffering obliterating atherosclerosis of the lower extremities arteries solely or in combination with diabetes mellitus (DM), were analyzed. The malleolar pressure index (MPI), regional systolic pressure (RSP), velocity of the volume blood flow (VVBF), rheographic index (RI), using test with nitroglycerine, postocclusion venous pressure (POVP) and intaosseous pressure (IOP) in tibiae were studied. The RI reduction, parallel to the arterial ischemia progression, was established.
