Mechanism of the tilt induced increase in collateral arterial resistance in patients with occlusion of the superficial femoral artery

Abstract: Resistance in collateral arteries bypassing an occlusion of the superficial femoral artery was studied in five patients before and during epidural blockade. The patients were placed on a tilt table and the measurements were performed with the patients both in supine and tilted position (40 degrees head up). Arterial blood pressure was measured directly in the brachial, common femoral and popliteal artery. Relative and absolute blood flows were calculated as the relative change in arteriovenous oxygen differenc… Show more
