Although the common femoral artery is the easiest and most widely accepted access site for cerebral angiography, atherosclerotic, aortoiliac, or femoral artery disease can preclude this approach. We describe our experience using the ulnar artery access site in a patient with bilateral aortoiliac occlusive disease. This article may be useful to neuroradiologists who encounter difficulty with oth...

A case of ulnar nerve entrapment in Guyon's tunnel caused by an aberrant palmaris muscle, associated with a patent median artery and duplication of the median nerve, is reported.

The catecholamine content of various blood vessels of the foreleg of the dog was measured by a fluorimetric method (48 vascular segments from 11 dogs) and also by bioassay (33 segments from 8 dogs). The results obtained by the fluorimetric method indicate that the average concentration of catecholamines in the brachial artery (0.14 /ig/g of wet tissue) was significantly lower than that in the u...

Introduction: Blood supply to the arm and forearm is conveyed by brachial artery its branches, radial ulnar artery. Variations in these arteries are being increasingly reported many studies. Most of variations observed mostly course branching pattern have been accounted be due developmental defect, from varied causes. 
 Materials Methods: In present study dissection was done on fifty seven...

A review of the literature concerning ischaemic complications following radial artery cannulation suggests that the Allen test has little predictive validity. Other methods of assessing the ulnar collateral circulation are discussed.
