[Complications of venous port systems : Radiological diagnostics and minimally invasive therapy].

INTRODUCTION: Documentation of a correct port placement is a routine investigation in radiology. This article describes typical complications of port catheters and minimally invasive treatment options which can guarantee further use without complications.

MATERIAL AND METHODS: From January 2009 to May 2010 a surgical port placement was carried out on 174 patients at the University Clinic in Mannheim and of these, 52 patients were admitted to our institute for radiological imaging of the port. Minimally invasive treatment options are presented based on the observed port complications.

RESULTS: Of the 52 patients 7 (13.5%) received a port catheter lysis. A successful port position correction was carried out in 3 (5.8%) patients with a malpositioned port catheter and port removal was recommended in 2 patients (3.8%) due to extensive arm venous thrombosis. A minimally invasive port catheter treatment allowed further use of the port system without operative revision in the corresponding patients. The measures were tolerated very well by the patients without postinterventional complications.
