Case Reports[The "pinch off" syndrome: a complication of implantable catheter systems in the subclavian vein].
We report the case of a 63-year-old male patient who received a subcutaneous Port-a-cath system in the right subclavian vein for administration of chemotherapy. Five weeks after successful use, flushing with NaCl 0.9% caused a painless subcutaneous swelling. Fluoroscopy confirmed a leakage below the right clavicle. ⋯ Two weeks later another leakage occurred and the catheter was removed definitively. Defective equipment was ruled out by the catheter producing company. The "pinch off" syndrome, a rare phenomenon of catheter compression and consecutive catheter fracture, is described, together with the diagnostic signs, the incidence and preventive measures suggested in the literature.
