title: Venous "lakes" of the hands.
abstract: Following pharmacologic vasodilatation, multiple vascular "lakes" were observed on angiograms of the hand in 55 patients. Most had no history of vascular anomalies or disease. The authors believe that these lakes are venous structures and that their filling is a physiologic phenomenon.
