RESUMEN
Objective To compare the technical success ,complication rates and comfort of the radiologic placement of central venous ports(CVP) via the internal jugular vein ,subclavian vein via subclavian region ,subclavian vein via supraclavicular region un‐der DSA guidance .Methods We retrospectively reviewed 188 CVP patients implanted at hospitals between December 2012 and De‐cember 2013 .The patients were divided into three groups according to the different catheter implantation sites ,internal jugular vein (group A) ,subclavian vein via subclavian region (group B) and subclavian vein via supraclavicular region (group C) .Intraoperative pain score ,technical success rates ,peri‐procedural ,as well as early and late complication rates were recorded based on the image fol‐low‐up and patient medical records .Results The technical success rate was 100 .0% without any lethal complications .The CVP re‐lated infections were occurred in each group with 1 patient ,but there was no statistics significant different(P>0 .05) .Subclavian vein thrombosis were occurred 2(2 .1% ,2/96) in group B ,which was recanalized after thrombolytic therapy ,and 1(1 .7% ,1/60) in group C ,which was completely occluded .The higher rate of catheter migration and kinking of catheter were occurred in group A and group C .The rate was statistically significant difference among the three groups (P0 .05) .Con‐clusion In DSA radiologic placement of a CVP via the subclavian vein via subclavian region is safe and efficient with more comfort‐able and lower complication rates ,which could be chosen priority .
