Basic Research on the Optimal Material for Sealing the Puncture Site of a Rupture-Free Balloon in PTEG, Allowing for Re-puncture

Abstract

We conducted basic research to identify the optimal material for sealing the puncture site of a rupture-free balloon (RFB) used in PTEG, allowing for subsequent re-puncture. Film dressing, hydrocolloid dressing, and cellophane tape were each applied to the puncture site of the RFB. A 10ml diluted contrast agent solution was injected into the RFB to verify whether the solution leaked out. While leakage occurred with film dressing and hydrocolloid dressing, no leakage was observed with cellophane tape. Sealing the initial puncture site of the RFB with cellophane tape effectively prevented deflation, thereby facilitating successful re-puncture.
