Hemometakinesia, the borrowing of blood by one part of the body for use by other parts or tissues, is a well regulated physiologic mechanism involving selective vasodilation and vasoconstriction. It has been shown, however, that diversion of blood flow following vascular reconstruction may impoverish tissues from which the blood flow is borrowed, causing ischemia in these vascular beds. Observations on 12 patients out of a group of 100 who had undergone vascular reconstruction of a limb deterioration. It is suggested that the type and site of the vascular disorder and the expected diminution of blood flow in other involved arterial circuits should be considered in selecting the most appropriate vascular surgical procedure. Searching for and recognizing the hemodynamic significance of a silent lesion in the carotid or gastrointestinal circuit or in a contralateral limb may avert a vascular crisis after the primary lesion has been successfully treated.
