The totally implantable catheter system has gained popularity as venous access when prolonged treatment is needed. Despite its frequent use, intravascular fracture and embolization of catheter fragments from implantable venous port-catheter systems present a rare but potentially life-threatening complication. Any implanted catheters should therefore be removed after completion of the treatment or the system's integrity should be monitored on a regular basis. ⋯ A chest radiograph showed a normal location of the port-system, but the distal fragment of the catheter had embolized into the right ventricle. The embolized fragment was extracted with a gooseneck snare technique and the reservoir of the system was removed under local anesthesia without any complications. The patient was free of symptoms at 7 seven months follow-up.

The authors encountered a very rare case of paradoxical brain embolism resulting from pulmonary arteriovenous fistula and coincident pulmonary embolism. Enhanced computed tomography was useful for diagnosing this infrequent condition.
