Consumption coagulopathy resulting from arterial aneurysm is an uncommon entity. Two patients, one with a femoral artery aneurysm and one with an abdominal aortic aneurysm containing fresh blood clot associated with a coagulopathy are presented. Reasonable preoperative control of the bleeding disorder with appropriate blood products followed by aneurysmectomy is recommended. Except to treat severe bleeding disorders associated with arterial aneurysms, heparin therapy is rarely necessary, as spontaneous reversal of the coagulopathy usually occurs. A high index of suspicion for the presence of an underlying arterial aneurysm as the cause for the consumption coagulopathy is necessary when no other etiology is obvious.

A case of abdominal aortic aneurysm which presented as retroperitoneal fibrosis followed by fatal disseminated intravascular coagulation is reported. A diagnostic aortogram should be considered in all cases of apparent idiopathic retroperitoneal fibrosis.

A patient with a relatively localized occult carcinoma of the lung and hemorrhage secondary to chronic disseminated intravascular coagulation (DIC) which continued for eight months is described. Despite continuing DIC two major operations were performed without excessive blood loss. Preoperative heparinization, in vitro clotting of the arterial graft, and temporary postoperative reversal of systemic heparin were utilized for abdominal aortic aneurysm resection. Blood product replacement therapy facilitated an emergency laparotomy. The patient was also managed successfully for several months without anticoagulant therapy. A hypothesis that vascular thrombi are not a necessary prerequisite for DIC is proposed. This hypothesis is based on the absence of thrombi or evidence of ischemia in this patient and in others and is supported by experimental observations made by other investigators.

Each of two patients harboring a stable abdominal aortic aneurysm manifested severe recurrent bleeding consequent to chronic consumption coagulopathy (CCC). Both underwent successful aneurysmectomy, but in only one patient did bleeding cease and depressed clotting factors return to normal activity. In the other patient, subsequent observations suggested that his coagulopathy actually resulted from occult pancreatic carcinoma. We propose here criteria for establishing stable aneurysm as the cause of CCC and demonstrate the efficacy of heparin in reversing the coagulation defect prior to surgical intervention. These cases also illustrate that the discovery of CCC accompanying stable aneurysm may signal the presence of another underlying disorder.

A case of abdominal aortic aneurysm associated with preoperative signs of disseminated intravascular coagulation is reported. The 69-year-old female patient presented with spontaneously appearing petechiae and bruising. She had 0.95 g.l-1 fibrinogen, 105 G.l-1 platelets, and 100 micrograms.ml-1 fibrin and fibrinogen degradation products. Investigations revealed an 80 mm diameter aneurysm of the abdominal aorta, extending from the coeliac trunk to the iliac arteries. Heparin 7,000 IU.day-1 resulted in a biological improvement for a week only. At that time, levels of coagulation factors were: 92% factor II, 88% factor V, 100% factors VII and X, 100% antithrombin III. Surgical cure of the aneurysm was nevertheless carried out. Twenty standard units of platelets, 8 g fibrinogen, four units of fresh frozen plasma, five homologous and two autologous red cell units were transfused during the procedure. No coagulation factors were necessary during the postoperative course, which was uneventful. The management of coagulation factor infusions, before or after aortic cross-clamping, is discussed.

Surgical repair of abdominal aortic aneurysm (AAA) is frequently associated with DIC. 15 patients affected by AAA were studied to evaluate the risk of consumption coagulopathy and the efficacy of daily low-dose calcium heparin prophylaxis. The coagulation parameters investigated showed a postoperative decrease of AT III activity levels and platelet count the other laboratory tests did not show any significant modifications. Low dose heparin was effective in preventing coagulation activity or thrombotic episodes. No thromboembolic complications were observed, except nonfatal myocardial infarction.

We reported three patients who developed disseminated intravascular coagulation (DIC) accompanying thoracic and abdominal aortic aneurysm. The first case, a 26-year-old man with dissecting aortic aneurysm developed DIC with clinical bleeding after operating on glaucoma. The administration of fibrinogen concentrates and antifibrinolytic agent made his DIC improve. The second case, a 70-year-old man with abdominal aortic aneurysm developed DIC showing large ecchymosis after angiography. His DIC disappeared after operation on aneurysm. The third case, a 73-year-old woman with thoracic and abdominal aneurysm developed laboratory-DIC without severe hemorrhagic diathesis. During antifibrinolytic therapy, platelet count, fibrinogen and fibrinogen degradation product (FDP) level improved. Since the treatment of the coagulopathy might be varied in the situation of the cause and clinical course, it is noted that anti-fibrinolytic therapy was effective in our two cases.

A 71-year-old male with disseminated intravascular coagulation (DIC) caused by abdominal aortic aneurysm was successfully treated surgically. He had aortic regurgitation, an old myocardial infarction, and nephrotic syndrome. The infrarenal part of the inferior vena cava, which was on the left side of the aneurysm, was temporarily transected during the surgical procedure. Preoperative heparin therapy was insufficient, but infusion of blood components during the operation and minimal dissection of the aneurysm were effective in controlling intraoperative hemorrhage. Hypofibrinogenemia and thrombocytopenia were normalized immediately after operation, and hemorrhagic diathesis was completely cured. In this case, the definitive treatment of DIC caused by an abdominal aortic aneurysm war removal of the lesion and the infusion of coagulation factors during the operation was effective in minimizing blood loss.

Disseminated intravascular coagulation (DIC) has been described as an occasional complication of abdominal aortic aneurysm. This is usually a perioperative coagulopathy, which may progress into a hemorrhagic diathesis. Rarely, DIC is present preoperatively as a result of the aneurysm itself. In the presence of additional pathophysiologic factors, a "compensated state" of secondary fibrinolysis may deteriorate into a clinically manifest coagulopathy. Heparin can be a useful adjunct in preoperative management of DIC, but definitive treatment requires surgical repair of the aneurysm. Long-term follow-up is essential to ensure that DIC is due to the aneurysm and that other disease processes are not overlooked. We report a case of DIC caused by an abdominal aortic aneurysm, with resolution after surgical treatment.

A case of severe acute intravascular haemolysis occurring after surgical repair of an abdominal aortic aneurysm in a 60-year old patient is reported. The operative conditions were difficult, requiring three laparotomies within 24 h, with rapid and profuse transfusion: 20 units of red blood cells, 31 of colloids, 11 units of fresh frozen plasma, 31 of diluted albumin and 41 of crystalloid solution. Evolution of the haemolysis became rapidly favourable under symptomatic treatment: forced diuresis (11.91 per 24 h) and alkalinization. None of the classic complications (acute renal failure, disseminated intravascular coagulation) arose. After review of various causes of severe acute intravascular haemolysis, its origin was probably mechanical in this case.
