Persistent left superior vena cava (PLSVC) is the most common thoracic venous circulation anomaly and discovered incidentally during hemodialysis catheter insertion. PLSVC may have some clinical implications for nephrologists. PLSVC can create difficulties during catheter insertion and cause serious complications; it can be mistaken for placement into other sites and cause inappropriate response such as catheter removal. Nephrologists who place hemodialysis catheters in the left jugular or subclavian vein should be aware of the existence of PLSVC.

Apelin and ADMA may have opposite impacts on the activity of NOS and production of NO. However, the circulating level and cardiovascular role of apelin are unclear in uremia patients with elevated ADMA. Our present study was to detect the serum level of apelin-13 and ADMA, and their correlations in maintenance hemodialysis (MHD) patients. ⋯ The serum concentrations of both ADMA and apelin-13 are increased in MHD patients without HF, and there were positive correlations between them predialysis. Both of them might affect patients blood pressure.
