Balloon-assisted coil embolization (BACE) of a wide-necked renal artery aneurysm using the intracranial scepter C compliant occlusion balloon catheter

Abstract

BackgroundTrue renal artery aneurysms (TRAA) are an uncommon pathology, with a prevalence of less than 1%. Treatment of TRAAs is generally recommended when the aneurysm sac equals or exceeds 2cms. Both wide-necked and main renal artery branch aneurysms represent a challenge for conventional endovascular coil embolization due to the risk of coil migration.Main bodyIntra-procedural remodeling of the aneurysm neck using Balloon Assisted Coil Embolization (BACE) is considered a suitable alternative in challenging cases of visceral artery aneurysms.Short ConclusionWe describe the novel use of the Scepter C (MicroVention Terumo, Tustin, CA) compliant double lumen neurovascular occlusion balloon in the treatment of a wide-necked branch TRAA in a patient with a solitary kidney.

Coil embolization of renal artery aneurysms: Simultaneous delivery of three microdevices with a novel 6-Fr guiding sheath

“…Modified techniques for embolization of wide-necked renal artery aneurysms have been described using the stent-assisted technique [10] , balloon-assisted technique [11] , and covered stents [12] . In the present case, a double-balloon remodeling technique, a technique borrowed from interventional neuroradiology practice [13] , was considered suitable to protect the 2 branches of the aneurysms.…”

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

“…We did not find studies reporting double-lumen balloon-assisted treatment of VAAs in the English literature, except for 1 case report. 17 In a multicenter study conducted by Martínez-Galdámez et al 18 not involving VAAs, complete and almost complete occlusion in 71 (90%) of 86 intracranial aneurysms was found in 7 months of follow-up. In all these patients, double-lumen balloons were used and stents were deployed through them, and the importance of stent deployment from double-lumen balloons without extra maneuvers of the operator was reported.…”

Endovascular coiling in the treatment of patients with renal artery aneurysms

“…The endovascular technique has the advantages of being minimally invasive, requiring a short stay, and the use of a percutaneous approach. Various endovascular options exist for RAAs, each have their advantages and disadvantages 3 , 4 , 9 , 10 , 11 , 12 ( Table ). Coil embolization, as in patient 2, is ideal for a sac-like aneurysm with a narrow neck.…”

“…For patient 3, we reported the successful endovascular management of an RAA in a solitary functioning kidney. Three previous cases of management of an RAA in a solitary kidney have been reported, including the use of a pipeline embolization device, 14 balloon-assisted coil embolization, 11 and a robotic surgical technique with partial RAA excision and tailored repair. 15 Our report of an RAA in a single functioning kidney has demonstrated successful management with the double catheter embolization technique.…”
