Endovascular balloon occlusion has become a standard mode of therapy in carotid cavernous fistulas. Many angio-architectural variations are, however, encountered in individual cases, some of which influence the therapeutic mode and outcome. We report on three patients with carotid cavernous fistulas treated by endovascular techniques.  相似文献

The medical records, radiographs, and pathologic specimens of ten patients with the diagnoses of nontuberculous mycobacterial infection and acquired immunodeficiency syndrome (AIDS) were examined. The radiographic findings of alveolar or nodular infiltrates and adenopathy were relatively nonspecific but in most cases led to bronchoscopic study or open-lung biopsy, which established the diagnosis. Bronchoscopic washings or sputum cultures, which frequently provided the first confirmation of infection, were always followed by positive blood or tissue cultures. In contrast to nontuberculous infection in immunocompetent hosts, disseminated infection was common, with evidence of extrapulmonary involvement in nine patients. On the basis of these findings, we recommend that any AIDS patient with sputum or bronchoscopic washings demonstrating nontuberculous mycobacterial organisms be tentatively classified as having disseminated infection while being evaluated with blood, bone-marrow, stool, and urine cultures, even if the chest radiograph shows no disease.  相似文献

Perceptions of the pregnancy experience, pregnancy intendedness, and partner status were compared in a sample of 30 women in the midtrimester. Half of the sample defined themselves as single and half as partnered. Interview data showed a full range in pregnancy intendedness and partner status, and shared areas of concern among the sample as a whole and areas of concern specific to single women. Single women's concerns clustered into four categories: decision-making, disclosure, social support, and legal issues.  相似文献

The management of a patient with haematuria following percutaneous nephrolithotomy is described. The patient underwent renal angiography to assess the cause of bleeding. A pseudoaneurysm arising from first left lumbar artery was incidentally discovered, which was then successfully embolized using an indigenously fabricated metallic coil and gel foam particles in the same sitting.  相似文献

The influence of bilateral adrenalectomy on hemopoietic stem cell (CFU) migration in mice has been studied. Formation of endogenous spleen colonies in lethally irradiated, leg-shielded mice was sharply increased by prior adrenalectomy, and this increase was not dependent on the volume of shielded bone marrow. Adrenalectomy was shown to increase endogenous spleen colony formation in sublethally irradiated mice as well. However, it had no affect on formation of spleen colonies in lethally irradiated mice injected with syngeneic bone marrow. The CFU content of murine bone marrow decreased acutely after removal of the adrenals, and this decrease was accompanied by a concomitant increase in the peripheral blood and splenic CFU. Thus, adrenalectomy appeared to have no affect on the splenic plating efficiency or proliferative rate of hemopoietic stem cells, but it did result in increased migration of stem cells from the bone marrow to the blood, and thence to the spleen. It is concluded that the adrenal steroids may be of physiologic importance in the regulation of ehmopoietic stem cell migration.  相似文献
