In 39 patients (13.5%) thrombotic device occlusion or subclavian vein thrombosis were detected.
Thromboses were treated by low-molecular weight heparins.
In 7 cases local thrombolysis was effective.
In 2 patients we have performed device explantation due to risk of thrombosis progression.
Mean time for venous thrombosis development was 3 months after intervention.
In 1 case non-massive pulmonary embolism has revealed.
Based on risk analysis male sex (p<0.05) and head and neck cancer (p=0.03) were justified as predictors for thrombotic complications (Figure 1).
Additionally we have analysed small group of patients with catheter malposition (n=15).
In 46.6% (n=7) thrombosis was identified and we suggest device malposition as a serious VTE risk factor
