  • Title: [Superior vena cava syndrome unrelated to central venous catheter in a patient on chronic hemodialysis].

    Abstract:
    A 67-year-old woman with end-stage renal disease (polycystic kidney disease) who had been on dialysis for 10 years came to our department for a second opinion about upper left arm edema homolateral to the arteriovenous fistula (AVF). Because of the suspicion of venous stenosis she had already been submitted to angiographic examination of the AVF which, however, did not show any occlusive process. In addition to the kidney problem, the clinical history included dilated cardiomyopathy, and 2 years earlier a biventricular implantable cardioverter defibrillator (ICD) had been placed. The patient had never had a central venous catheter (CVC). She presented a typical superior vena cava syndrome picture with arm, neck and hemifacial edema and superficial cutaneous venous reticulum. The venous pressure during extracoroporeal circulation was high and blood recirculation was documented. Angio-CT was performed to look for a compressive process in the chest, but this was excluded. We then performed a new trans-AVF angiography to study extensively the axillary-subclavian-superior vena cava district. At first, no stenosis or thrombosis was observed, but the presence of ICD and its leads (left-sided implanted) in the anonymous vein created obstacles to diagnosis. Repeated injections of contrast medium and focusing imaging on the leads route allowed us to highlight a venous stenosis in the anonymous vein. Transluminal angioplasty was successfully carried out during the same procedure. 1) In hemodialysis patients the appearance of signs of intrathoracic vein drainage obstacles is not always associated with previous CVC implantation; 2) in the hemodialysis patient, any device (PM, ICD) should be implanted contralaterally to the fistula arm in order to avoid the risk that a venous stenosis may cause AVF dysfunction.
