Double-Lumen Balloons,Are They Only Useful in Neurointerventions? Preliminary Outcomes of Double-Lumen Balloon-Assisted Embolization of Visceral Artery Aneurysms

Abstract

Objectives:

This study aimed to assess the feasibility and results of double-lumen balloon-assisted embolization of visceral artery aneurysms (VAAs).

Methods:

Nine patients (mean age, 55.3 ± 10.8 years) diagnosed with VAA (superior mesenteric, n = 5; splenic, n = 2; renal, n = 2) and undergoing double-lumen balloon-assisted embolization were included in this study. Magnetic resonance angiogram (MRA) was used in the 6-month follow-up to assess the aneurysms and patency of the parent arteries.

Results:

All patients were successfully treated with no reports of morbidity or mortality. Residual filling of the aneurysm neck was detected in 2 patients at the end of the procedure, but those parts were found to be stable in the sixth-month MRA. In 1 patient with renal aneurysm, a stent had to be deployed using a double-lumen balloon catheter because of the prolapse of the coil into the main artery. In another patient with a very large-necked superior mesenteric artery aneurysm, additional coils could be used at the same time thanks to the double-lumen balloon as the coils were not stabilized enough during embolization with the microcatheter coils. Liquid embolic agent was also used in this patient from the same lumen because of the large diameter of the aneurysm.

Conclusions:

Double-lumen balloons, which are mostly used in neurointerventional procedures, can be efficiently used as in the treatment of VAAs due to their ability to deploy stent and perform coil-liquid embolization through 1 lumen.
