Well, as a medical translator I have to admit I had to research this subject first, too, as the medical dictionary did not give any answers. I finally found some english articles that do use the word paravasation, please see article below (paravasation in caps) and references.

Objective: Previous publications about the complication rate of Port-a-Cath systems have described results between 8 - 20% including early and late occuring problems. These high complication rates are possibly related to frequently changing surgery teams. In order to evaluate the influence of a well-trained, permanent Port-a-Cath implantation team on the complication rate, all implantations were performed by one surgeon and three assisting nurses.
Materials and methods: We used titanium ports connected with a polyurethane catheter (Sims-Deltec, Inc., St. Paul, USA). The implantation was done in local anaesthesia via the cephalic vein, or by puncture of the subclavian vein. The correct location of the catheter tip was controlled by X-ray. The port was fixed to the pectoral fascia.
Results: 500 Port-a-Cath systems were implanted between 5.1.1996 and 25.11.1999. The mean overall port duration was 214 days. The complication rate related to the surgery procedure was 2,6% (13/500) as were: 3 wound infections, 3 pneumothoraces, 6 bleeding episodes postoperatively, 1 lymphatic fistula. The complication rate related to the use of the Port-a-Cath system was 4,4% (22/500) as were: 8 catheter infections, 3 reversible catheter occlusions (there may be late occlusions not known to us), 6 subclavian thromboses, 4 secondary dislocations of the catheter tip into the jugular vein,
Port removal was necessary in 15 cases.
Conclusion: The overall complication rate was remarkably reduced due to a small, well trained surgery team, to strong adherence to SOPs and a consequent training of all staff members allowed to use the port systems (nurses and physicians).
