Perioperative evaluation of bleeding diathesis.

The differential diagnosis of a long APTT with a normal prothrombin time can be due to either a clotting factor deficiency or the presence of an inhibitor, which can be distinguished by using a plasma-mixing study. The various clotting factor deficiency states are reviewed. Clinical bleeding following cardiac bypass surgery due to acquired factor V and thrombin antibodies is also reviewed.

Intra-abdominal angiosarcoma developing in a capsule of a foreign body: report of a case with associated hemorrhagic diathesis.

BACKGROUND: Angiosarcoma occurs very rarely in the gastrointestinal tract and can present great diagnostic difficulty, especially when it is associated with intraabdominal abscess or granulation tissue. CASE PRESENTATION: We report a case where the angiosarcoma was diagnosed after the occurrence of disseminated angiosarcoma and concurrent hemoperitoneum. The tumor developed in the fibrous capsule of a foreign body, which was possibly related to the previous appendectomy twenty years ago, and became a widely disseminated malignant neoplasm in the abdomen. After the operation, the patient's course was dominated by a fatal consumptive coagulapathy. Pathologic examination of the multiple intra-abdominal lesions showed the histological and immunohistological characteristics of the angiosarcoma. CONCLUSION: Even though angiosarcoma in the gastrointestinal tract is extremely rare, when dealing with intraabdominal abscess or the gastrointestinal bleeding in patients who have undergone surgery or radiation therapy in the past, the possibility of angiosarcoma should be considered. To make the definite diagnosis of angiosarcoma and to avoid the misdiagnosis of foreign body granuloma, thorough histological examination and immunohistochemical staining may be prerequisite.

Anesthetic considerations in diffuse bleeding diathesis of uncertain origin.

This is a report of a case of a diffuse bleeding tendency in a pregnant woman who presented for emergency splenectomy with a tentative diagnosis of thrombotic thrombocytopenic purpura. The influence of multiple organ dysfunction in the selection of appropriate monitors and the anesthetic technic in such cases are complex.

Prospective reevaluation of the association between thrombotic diathesis and legg-perthes disease.

BACKGROUND: Legg-Perthes disease is associated with ischemia of the capital femoral epiphysis in children. Thrombophilia has been implicated as a potential cause of the condition, and screening of patients with Legg-Perthes disease for thrombophilia has been recommended. We analyzed the value of screening for inherited thrombophilia in patients with Legg-Perthes disease by examining the association between Legg-Perthes disease and abnormalities in the thrombotic pathway. METHODS: A random series of consecutive patients with Legg-Perthes disease were prospectively enrolled in this study. Assays for the detection of factor-V Leiden mutation and the plasma concentrations of protein C, protein S, antithrombin III, and lipoprotein (a) were performed on plasma samples from children with Legg-Perthes disease, and the results were compared with those for pooled plasma from normal controls. Plasma concentrations below the 95% midrange of the control values were classified as protein deficiencies. The estimated population frequency of each coagulation abnormality was compared with the proportion of the study group with the corresponding abnormality. RESULTS: The proportion of abnormalities observed in the study group did not differ from the estimated population frequency for protein C, protein S, antithrombin III, or factor-V Leiden mutation. A lipoprotein (a) level of >30 mg/dL (>1.07 micro mol/L) was found in 16% of the study group. CONCLUSIONS: Our data do not suggest that thrombotic diatheses due to deficiency of protein C, protein S, or antithrombin III or due to factor-V Leiden mutation are major causes of Legg-Perthes disease. The elevated levels of lipoprotein (a) in children with Legg-Perthes disease suggest that they may be at risk for atherosclerosis as adults.

Hemorrhagic diathesis, mesenteric hematoma, and colic associated with ingestion of sweet vernal grass in a cow.

A 4-year-old Holstein cow from a farm where 2 cows had recently died suddenly was referred for evaluation of acute severe colic. Right flank laparotomy revealed a large mesenteric hematoma. Within 14 layer chromatographic analyses of the moldy hay and blood from the necropsied cow and the hospitalized cow were positive for dicumarol. A diagnosis of sweet vernal poisoning was confirmed on the basis of clinical and toxicologic findings. The cow was treated with supportive therapy, blood transfusions, and vitamin K1 and recovered without complications. Because sweet vernal grass is becoming common in certain areas and the use of round bales is commonplace, practitioners should be aware of the potential for this toxicosis.
