A consumption coagulopathy was demonstrated in each of four patients with either ruptured aneurysm of the aorta or a dissecting aortic aneurysm. The most prominent features of this disorder were (1) a prolonged prothrombine time due to a decrease of one or more clotting factors, and (2) formation of fibrin and fibrinogen degradation products. Recognition of this coagulation disorder could be a valuable diagnostic tool to differentiate a ruptured or dissecting aortic aneurysm from other conditions with a similar acute onset. The coagulation disorder could be due to liberation of coagulant material from the aortic wall into the circulation or to an accumulation of clotting factors at the site of the lesion, secondary to the local exposition of tissue factors from the torn arterial wall. The probability of the latter mechanism is suggested by the local increase of radioactivity after the injection of 125I-fibrinogen.

Disseminated intravascular coagulation (DIC) is not a rare phenomenon in the neurosurgical field. We investigated the therapeutic effect of [Ethyl p - (6-guanidinohexanoyloxy) benzoate] methanesulfonate (FOY) for DIC or Pre-DIC states associated with neurosurgical disorders. During the previous three and half years, a total of 52 cases have been admitted to Shinshu University Hospital and its affiliated hospitals with DIC or Pre-DIC states due to brain disorders (group A) associated with head injuries (19 cases), subarachnoid hemorrhages caused by ruptured aneurysm (12 cases), intracranial hemorrhages and infarctions (5 cases), arteriovenous malformations (2 cases) and spinal cord injury (1 case), and with those states due to brain and another disorders (group B) associated with infections (7 cases), shocks (2 cases) and intoxications by drugs (2 cases). FOY was administered continuously for all patients. Clinical manifestations and laboratory data were analyzed statistically. Platelet count improved from during the 7th to the 10th day after starting FOY. It improved significantly in cases with a high DIC score and the improvement was not influenced by platelet transfusion. FDP, fibrinogen, prothrombin time and antithrombin-III also improved. DIC score remarkably improved in cases with an initial high DIC score. Hemorrhagic symptoms were recognized in 19 cases before administration of FOY and 14 of them (74%) improved after the treatment. Dysfunction of organs was recognized in 28 cases, of which 5 cases (18%) improved. Twenty-nine of 52 cases (56%) were still alive. Only two patients died due to DIC. There were no side effects associated with administration of FOY.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of systemic lupus erythematosus (SLE) with subarachnoid hemorrhage due to a ruptured intracranial aneurysm is reported. A 31-year-old woman who had been treated with steroid for SLE was admitted to our department with severe headache, and nausea. CT scan showed subarachnoid hemorrhage and the left carotid angiogram revealed a small aneurysm at the supraclinoid portion of the left internal carotid artery. She had no neurological deficit. Hematological examination on admission showed disseminated intravascular coagulation (DIC), therefore, we decided to perform an intentionally delayed operation. In the meantime we treated the patient for DIC with FOY and methylprednisolone. The operation was performed after two weeks, when DIC had been eliminated completely. Postoperative hematological examination showed severe thrombocytopenia. We considered that SLE had come to the fore again, so we used Danazol in company with FOY and steroid. It seemed that Danazol was very effective for her. She was discharged about two months after admission with no problem. Cerebral apoplexy, such as cerebral infarction and cerebral hemorrhage, has often been seen in SLE, but subarachnoid hemorrhage due to a ruptured aneurysm is very rare. We could find only five reports of this phenomenon. Their prognoses were all, unfortunately, poor. It should be born in mind for therapy that a patient in SLE has a tendency to bleed. It seems that repeated hematological examinations and quick and proper management are important. We think that the aneurysmal formation in SLE is due to lupus vasculitis or the fragility of blood vessels due to a long use of Steroid.

A retrospective review was done of all patients undergoing surgical repair of abdominal aortic aneurysm (AAA) on whom coagulation studies were obtained. Those patients with laboratory documented disseminated intravascular coagulation (DIC) were selected and their clinical records reviewed. This included 7 patients studied in the periods 1964-1965 and January 1971-July 1973. Of these 7 cases, 4 occurred in patients undergoing emergency operation for ruptured aneurysm and 3 were in elective cases. All 7 patients exhibited clinical evidence of abnormal bleeding, while 6 of the 7 progressed rapidly to renal shutdown. The seventh patient recovered spontaneously. Of the 6 patients with full blown clinical and laboratory evidence of DIC, 2 recovered. Both cases received heparin therapy and multiple hemodialyses. A third patient was started on heparin but died at 36 hours in heart failure. All 3 patients receiving heparin showed clinical cessation of abnormal bleeding and disappearance of soluble fibrin monomer complexes within 24 hours of starting therapy. The study suggests a higher incidence of DIC than has previously been appreciated in both the emergency and elective repair of AAA. The prompt recognition and treatment of this complication may reverse the abnormal intravascular clotting, minimize its more serious results and avoid futile and dangerous operative intervention.

Two cases of abdominal true aortic aneurysm (AAA) associated with disseminated intravascular coagulation (DIC) were reported. Case 1 was an 81-year-old male who was admitted because of hematoma on the left leg and in whom was found by MRI an aortic aneurysm of 14 cm in diameter. Coagulation studies indicated DIC by revealing thrombocytopenia, hypofibrinogenemia and increased level of FDP. DIC was well controlled by surgical repair of the aneurysm after the administration of a small dose of heparin. Case 2 was a 60-year-old male who was admitted because of lumbago and hematoemesis and in whom was found by CT and echography an aortic aneurysm of 5.5 cm in diameter. Coagulation studies indicated DIC by revealing thrombocytopenia and an increased level of FDP. On the 2nd hospital day, he suddenly died due to the rupture of the aortic aneurysm. In most of 9 cases with AAA without DIC, plasma levels of thrombin-antithrombin III complex, plasmin-alpha 2 plasmin inhibitor complex and FDP-D dimer were also elevated. These findings indicate that the coagulation and fibrinolysis systems were generally activated in patients with AAA, and that DIC tends to occur in patients with a giant aortic aneurysm or an impending ruptured aneurysm.
