Symptomatic unruptured giant aneurysms: medical treatment.

Medical hypotensive therapy, usually limited to cases with proved haemorrhage, has now been applied to three cases of giant or "very large" aneurysm which were symptomatic but unruptured. All three patients improved. With three cases, the only conclusion that is drawn at this time is that medical treatment may indeed offer something for even this category of aneurysm as well as for the much more common smaller aneurysms that have ruptured and whose excellent response to both early and long term medical hypotensive therapy has already been established.
