vascular acess

M Geiger, K Deloose, J Callaert, M Bosiers
Surgical endarterectomy has been considered the prefered technique for treating the common femoral artery (CFA). Although favorable endovascular treatment results of the CFA have recently become available, losing the groin area as an important acess site is still the major concern for this technique to become the golden standart. Nevertheless, the endovascular approach has shown, through several studies, including our experience, the capacity to establish itself as a complementery treatment for the modern vascular surgeon...

Intravascular noradrenaline infusion may cause vasodilatation or vasoconstriction in subcutaneous adipose tissue, whereas sympathetic nerve activity causes vasoconstriction only. This discrepancy may be due to a differential distribution of alpha- and beta-adrenoceptors in relation to adrenergic nerve terminals in the adipose tissue vessels. In order to test this hypothesis the extent of prejunctional supersensitivity to noradrenaline was studied after blockade the neuronal uptake of noradrenaline with cocaine...

In order to ascertain whether trivalent rare earth ions such as lanthanum (La+++) penetrate the cell membrane under physiological conditions, the extracellular and cellular distribution of promethium (147 Pm), a carrier-free rare earth radioisotope, was examined in rabbit aortic smooth muscle. As the duration of incubation was lengthened, uptake of 147Pm continued to increase; it was inhibited by La+++ and other rare earth ions (Nd+++, Lu+++) only when the 147 Pm/rare earth concentration ratio exceeded 1:10(6)...
