[Reconstruction of mediastinal veins in same side dialysis shunt].
Centralvenous obstruction is a rare however typical lesion with patients on chronic hemodialysis. A still functional arteriovenous shunt in its run-in can cause serious disorder, especially painful congestion and an insufficient dialysis. Should the shunt be maintained, a run-off reconstruction is required. 13 patients were treated with a centralvenous obstruction combined with a complication of the shunt. In 8 patients the intervention was either impossible from the beginning or finally proved to be not successful after repeated recanalisations. 6 out of these patients underwent a transsternal reconstruction of their bypass (a total of 7 interventions). 2 patients died perioperatively, 2 patients died 1 year, respectively 1 1/2 years later with a still intact reconstruction, 2 patients are still alive. Their reconstruction has been working for two, respectively three years. The bypass material was large-calibrated e-PTFE with external support. Compared to conventional indications the catheter techniques proved to be less effective in the treatment of central venous obstruction. One year after the first intervention only three out of seven shunts could still be used for the dialysis. The longest symptom-free period was 12 months. The operative reconstruction is indeed very effective but it implies considerable risks and effort. This method cannot be recommended to patients on chronic dialysis who are in a poor condition.
