PURPOSE To compare the frequency and extent of pulmonary embolism (PE) occurring during pulse-spray pharmacomechanical thrombolysis (PSPMT) of clotted hemodialysis grafts with use of either urokinase (UK) or heparinized saline (HS). Postintervention primary patency and complication rates were compared for each method of thrombolysis. METHODS AND MATERIALS(More)
PURPOSE Low-power ultrasonic (US) energy is capable of clot dissolution in vivo. The combination of US energy plus alteplase may further accelerate clot lysis; however, the effects of cavitation could potentially denature and inactivate the lytic protein. The purpose of this study was to determine the bioactivity and stability of alteplase when exposed to(More)
We present three cases of the rare hepatosplenic T-cell lymphoma (HSTCL); two patients suffering from Crohn disease who developed HSTCL on azathioprine without exposure to biologicals, and a third patient who had psoriasis treated using etanercept, cyclosporine and methotrexate. The evidence for an association between HSTCL and immunosuppressive drugs and(More)
