PURPOSE: We aimed to illustrate the benefits of using warmed glue for viscosity reduction via the triaxial microballoon system for the treatment of various vascular disorders.


METHODS: Seven patients who underwent 10 treatment sessions for hemoptysis, type II endoleak, post-pancreatic surgical bleeding, spontaneous retroperitoneal bleeding, or ovarian tumor bleeding were evaluated based on technical and clinical outcomes. In the procedure, the triaxial system, consisting of a 4.5-Fr guiding catheter, a 2.8-Fr microballoon catheter, and a 1.9-Fr no-taper microcatheter, was advanced into the target lesion. Glue (33% n-butyl cyanoacrylate mixed with Lipiodol) warmed to 40°C was injected under balloon occlusion.


RESULTS: The common hepatic, right bronchial, intercostals, internal mammary, costocervical, lateral thoracic, superior thoracic, thoracoacromial, inferior thyroid, iliolumbar, lumbar, internal pudendal arteries, and branch of the inferior mesenteric artery were successfully embolized; 100% technical success and 100% clinical success were obtained after each session.


CONCLUSION: Our modified balloon-occluded glue embolization may lead to better handling with more distal glue penetration capability.
