It is well known that abnormalities of coagulation and fibrinolysis frequently take place during the course of cerebrovascular diseases. In this paper, coagulation and fibrinolytic studies were performed during the course of acute stage through chronic stage of subarachnoid hemorrhage. Tested items were partial thromboplastin time, prothrombin time, FDP, alpha 2-plasmin inhibitor, antithrombin III, fibrinogen, besides, fibrinopeptide A (FPA), and fibrinopeptide B beta (FPB beta) which were being worthy of note. ⋯ Increase of fibrinogen delayed from the peaks of FPA and FPB beta showing the peaks at the seventh to the fourteenth day from the onset of subarachnoid hemorrhage. In three cases with symptomatic vasospasm, FPA and FPB beta showed maximal values two to four days prior to the appearance of symptomatic cerebral vasospasm. Other tests were all within normal limits.(ABSTRACT TRUNCATED AT 250 WORDS)
