A newly developed double lumen microballoon catheter with a side hole: initial experience of intraarterial infusion chemotherapy and/or embolization.

PURPOSE

To introduce a newly developed double lumen microballoon catheter with a side hole for intraarterial infusion chemotherapy and/or embolization.

METHODS AND MATERIALS

Seven patients with malignant tumors, for whom superselective catheterization was considered difficult or had failed, underwent intraarterial infusion chemotherapy and/or embolization with the 3.3-Fr microballoon catheter. The catheter has a double lumen and a side hole to facilitate infusion from the proximal end of the balloon. The balloon was placed on the distal side of the target artery branching site. Inflation of the balloon and occlusion of the main lumen with the tip of the occlusion device allowed for intraarterial infusion chemotherapy and/or embolization of the target artery via the side hole.

RESULTS

Successful intraarterial infusion chemotherapy and/or embolization with the microballoon catheter was performed in all patients with no complications.

CONCLUSIONS

The newly developed microballoon catheter achieves intraarterial infusion chemotherapy and/or embolization without the need for superselective catheterization.
