title: Right atrial thrombosis associated with hemodialysis catheter: first description of recurrence in a poorly understood problem.
abstract: Catheter-related right atrial thrombosis (CRAT) is an underreported and potentially life-threatening complication of central venous catheter in hemodialysis patients. The accurate incidence is unknown, with reported rates ranging from 2 to 12.8% [1] in series, up to 29% [2] in a postmortem prospective study, and high mortality rates (18%) [1]. The optimal treatment for CRAT is controversial and nonsystematized, including anticoagulation, thrombolysis, and surgical thrombectomy. We report two cases of CRAT in dialysis patients, who underwent surgical thrombectomy. One case required reintervention because of recurrence, a first reported case in hemodialysis population.
