Suppurative thrombophlebitis of the superior vena cava.

A 22-year-old woman, a neurosurgical comatose patient developed suppurative thrombophlebitis of the superior vena cava due to Klebsiella pneumoniae, as a complication of catheterisation for parenteral nutrition. The diagnosis was established by gallium scan, computed tomography and digital vascular imaging. Conservative treatment with antibiotics and heparin resulted in the emergence of a resistant mutant of the causative agent. The infection could only be eradicated after surgical thrombectomy.
