Primary Stenting Is Not Necessary in Benign Central Venous Stenosis

Initial and long-term outcomes of Percutaneous Transluminal Angioplasty for central venous stenosis or occlusion in chronic hemodialysis patients: Analysis of 363 lesions in single center

“…We compared the primary patency between 196 lesions treated by balloon angioplasty and 111 lesions treated by stent placement, disaggregated by de novo and restenosis lesions. The number of lesions included in this study is larger than those in previous studies [15][16][17]24,[27][28][29]. There was no signifi cant difference of primary patency after balloon angioplasty and stent placement for de novo lesions.…”

“…Kaneko We performed stent placement for insuffi cient dilatation with fl ow-limited dissection and frequent recurrence of occlusion after balloon angioplasty, and for long CTO lesions [8][9][10][11][12]26]. The long-term outcomes of stent placement for central venous lesions are not satisfactory and some studies have found no signifi cant differences with respect to patency rates after balloon angioplasty and stent placement [15,16,24].…”

“….000051 necessitating repeat interventions. In previous studies, the primary patency rates after PTA at 6 and 12 months were 50-70% and 20-30%, respectively, and the assisted patency rates at 6 and 12 months were 70-95 % and 70-90%, respectively[15][16][17]24]. In our study, the primary patency rates of de novo lesions at 6 and 12 months (71.2% and 40.4%, respectively) were signifi cantly higher than those of restenosis lesions (51.5% and 26.2%, respectively; P = 0.0004); the assisted patency rates of de novo lesions at 12 and 36 months were 94.4% and 89.0%.…”
