[Manifestation of pneumothorax 7 days after port implantation. Report of a single case].

The subcutaneous implanted venous port device offers a safe central venous access and allows for ambulatory treatment. This case report describes a late manifestation of a pneumothorax after venous port implantation which, in fact, is a rare but significant complications. The lack of a correlation of the signs and symptoms with the interventional procedure may lead to inadequate or delayed treatment. The immediate postprocedural X-ray can be false negative when air leaks into the pleural cavity very slowly. Therefore both patients and referring physicians should be informed about the possibility of the late manifestation of a pneumothorax.
