Abstract:
The authors performed a para-axial central venous stent (p-CVS) placement in 38 patients and implanted the stent without having to remove the functioning port. No difficulties were experienced in catheter function with p-CVS. In-stent stenosis was seen in 6 of 24 patients in the p-CVS group and in 6 of 18 patients in the intrastent venous stent placement group (P = .333). No complications occurred in any patient with p-CVS when the venous port was removed. Thus, p-CVS can be an alternative way to insert a CVS in patients who already have a functioning venous port.
