Aim. The aim of this prospective study is to evaluate the effectiveness of Color-Doppler Ultrasound in preventing venous thrombosis in 40 cancer patients fitted with a port-a-cath device.
Methods. We selected two groups of cancer patients with a port-a-cath device: group n° 1: 20 patients with neck vessels screening with Color-Doppler Ultrasound performed pre-operatively and every 15 days till the third month after the device placement; group n° 2: 20 with Color-Doppler Ultrasound screening performed pre-operatively and 30, 60 and 90 days after placement.
Results. Incidence of deep venous thrombosis was 2,5%. In group n° 2 we observed no case of venous thrombosis. In group n° 1 we registered one case of asymptomatic venous thrombosis 15 days after placement. He was treated with low molecular weight heparin and was completely revascularized.
Conclusions. Venous thrombosis in patients fitted with central venous catheter is always a progressive but slow phenomenon. The incidence in the first months after the placement is high, the most critical being the first three weeks after the positioning. Color-Doppler Ultrasound screening every 15 days in the first three months after the implantation is a useful instrument in early detection of venous thrombosis and can enable prompt treatment.
