RESUMEN
A retrospective study of 95 patients was undertaken to compare digital subtraction angiography (DSA) and conventional arteriography of the hand. Eighty patients had conventional angiography and 15 had DSA. In comparison with conventional angiography, DSA is more cost-efficient and facilitates outpatient angiography. It provides images as acceptable as those of conventional angiography. We conclude that intra-arterial DSA is now the procedure of choice for angiographic mapping of the digital arteries.

The arteriograms of sixty-two patients with chronic ischemia of the hand and fingers were reviewed. Twelve patients were considered to have Raynaud's disease. Thoracic outlet syndrome caused ischemic symptoms in thirteen patients. Arteriosclerosis obliterans affected twenty-two patients. The signs of arteriosclerosis are described including irregular constrictions, multiple occlusions and the corkscrew pattern of the collateral arteries. The differential diagnosis includes thromboangiitis obliterans and collagen vasculitis.
