Non-aneurysmal SAH with a perimesencephalic pattern of bleeding has a benign course and excellent short-term and long-term prognosis. Patients with non-aneurysmal SAH with an aneurysmal pattern of bleeding have more complications, and the initial clinical situation has a significant impact on their prognosis.

Oral anticoagulants are drugs commonly used in the prevention of vascular diseases, especially in embolic-type processes. Although several studies have assessed the possibility of using them in arterial processes, the experience has not been satisfactory so far. Heart diseases with major emboligenic flow are still the main indication, while the prevention of other low-risk heart diseases and treatment of large- or small-artery disease can be based on antiaggregant treatment. Other groups study the problem in large series.
