摘　　要：BACKGROUND Conventional recanalization techniques may fail in patients with completely occluded superior vena cava(SVC).AIM To analyze the effectiveness and complications of sharp recanalization for completely occluded SVC.METHODS This was a retrospective study of patients that underwent puncture and recanalization of the SVC between January 2016 and December 2017 at our hospital.Sharp recanalization was performed using the RUPS-100 system.The patients were followed for 12 mo.The main outcomes were the patency rate of SVC and arteriovenous fistula flow during dialysis.RESULTS The procedure was successful in all 14 patients(100%).Blood pressure in the distal SVC decreased in all 14 cases(100%)from 26.4±2.7 cmH2O to 14.7±1.3 cmH2O(P<0.05).The first patency rates of the SVC at 24 h and at 3,6,9 and 12 mo after sharp recanalization were 100%,92.9%,85.7%,78.6%and 71.4%,respectively.There were two(14.3%)severe,one(7.1%)moderate and one(7.1%)minor complication.The severe complications included one case of pericardial tamponade and one case of hemothorax.CONCLUSION The results suggest that sharp recanalization can be an additional tool to extend or renew the use of an occluded upper extremity access for hemodialysis.This could be of use in patients with long-term maintenance hemodialysis in whom the maintenance of central venous access is often a challenge.
