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

We report a periorbital arteriovenous fistula that was treated with direct sac puncture N‐butyl cyanoacrylate embolization under controlled inflow and outflow. The efficacy of this technique in a periorbital lesion is discussed. 相似文献

The factors controlling stem cell recirculation. i. Migration of hemopoietic stem cells in adrenalectomized mice 总被引:1,自引:1,他引:0
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

The management of depression remains a constant challenge in clinical practice. This is largely due to the fact that initial treatments frequently do not lead to remission and recovery. The current treatment approach involves lengthy trial-and-error periods. It would be beneficial to have early reliable predictors to determine whether patients will respond to treatment or not. Electroencephalography (EEG) derived biomarkers namely change in the activity of EEG frequency bands, hemispheric alpha asymmetry, theta cordance, the antidepressant treatment response index (ATR) and evoked potentials have all been shown to predict response to a variety of antidepressant medications. However, the neurobiology in support of this association has been largely unexplored. In this review, we discuss biological mechanisms for each EEG derived biomarker predictive of treatment response. Validating such biomarkers will not only greatly aid clinicians in selecting antidepressant treatment for individual patients but will also provide a critical step in drug discovery. 相似文献
