Since 2009, the (CCSVI) model of multiple sclerosis has drawn much attention, and the associated surgical ‘venoplasty' interventions have often been advertised as a novel idea. In fact, it is a new incarnation of various vessel-based therapies attempted for multiple sclerosis in the past, dating back to the 1930s, when Tracy Jackson Putnam (1894-1975) attempted pharmacological anticoagulation. This was followed in the 1940s by Richard M. Brickner's (1896-1959) studies of vasodilatory drugs, which further inspired trials of sympathectomy and ganglionectomy. In the 1950s, Ilya Mark Scheinker (1902-1954) studied vasopressor therapy, while Roy Laver Swank (1909-2008) investigated the effects of a low saturated fat diet in his patients. This paper discusses the longer history of these therapeutic endeavours and the aetiological theories that inspired them.
