Figure 1. 75-year-old male with unresectable liver metastases originating from gastric cancer (patient number 2, Table 1

). (a) Transverse non-enhanced brain CT before implantation shows no remarkable findings in the left thalamus. (b) Transverse non-enhanced brain CT after implantation of the port-catheter system and the onset of brain infarction symptoms (see Table 1

) shows a low density area in the left thalamus (arrow) diagnosed as a brain infarction.

Figure 2. 60-year-old male with unresectable hepatocellular carcinoma (patient number 4, Table 1

). (a) Posteroanterior chest radiograph shows the inserted catheter and a pronounced redundant catheter looping in the aortic arch (arrow). (b) Anteroposterior digital aortic arteriography performed after the onset of brain infarction shows a pronounced redundant catheter looping in the inserted catheter (arrow) in the aortic arch. This passes through the region where the left common carotid (arrowhead) and the right brachiocephalic artery (open arrow) originate.

Figure 3. 55-year-old male with unresectable liver metastases originating from colon cancer. Posteroanterior chest radiograph shows no pronounced redundant catheter looping (arrow) in the inserted catheter in the aortic arch. Note that the patient did not exhibit any brain infarction complications.
