ABSTRACT
A 52-year-old man presented himself to his family doctor for uremia associated with prerenal acute renal failure. A 12 Fr vascular access catheter was inserted via the right internal jugular vein for emergency dialysis. A contrast-enhanced computed tomography (CT) scan revealed that the catheter had penetrated the right internal jugular vein, perforated the right subclavian artery, and reached the ascending aorta. Under general anesthesia, we completed the procedure with a pull-through technique between the bilateral brachial arteries. A vascular occlusion balloon was inserted from the left brachial artery and a GORE VIABAHN stent graft was inserted from the right brachial artery. The postoperative course was good and he has been free from hemorrhagic episodes. He was transferred to the referring hospital on postoperative day 2.
ABSTRACT
A 77-year-old-woman was hospitalized at our institution following the diagnosis of severe aortic and mitral stenoses. Although she had thrombocytopenia before surgery, bone marrow examination revealed no abnormality. Thrombocytopenia was thought to be caused by shear stress accompanying valvular diseases. She underwent surgery for the replacement of aortic and mitral valves and the resection of left ventricular outflow tract myocardium. Because the mitral valve involved the calcification of the annulus the valve replacement was performed after decalcification using CUSA. After surgery, she experienced a transient sick sinus syndrome ; however, the overall course was good, and the platelet counts spontaneously recovered. More than 12 months have passed since surgery, but the platelet counts remains around 110,000.
