“…A second study, describing the use of the Scepter Mini balloon microcatheter, described 34 instances of balloon use in 20 patients across multiple centers. 9 The mean diameter of the catheterized blood vessel was 1.9 mm with technical failures occurring in 4/23 embolizations. 9 There were no complications directly related to the Scepter Mini, and the technical failures were all due to insufficient stability of the balloon and distal catheter tip within the target vessel.…”

Background The use of liquid embolic agents in the endovascular treatment of dural arteriovenous (dAVFs) fistulas and brain arteriovenous malformations (AVMs) has become common practice. The use of dual lumen balloon microcatheters has greatly improved the efficacy of liquid embolization. The purpose of this series is to discuss our early experience with the Scepter Mini dual lumen balloon microcatheter. Methods A retrospective chart review was performed of all patients who underwent embolization with the Scepter Mini dual lumen balloon at a single institution. Technical details and procedural complications were recorded for each case. Results In total, 10 Scepter Mini dual lumen balloon microcatheters were used in nine patients. All patients except two were treated for AVMs. Technical success was achieved in all but one case where one balloon had to be discarded due to precipitation of the tantalum powder. Average vessel diameter where the balloon was inflated was 1.1 mm (0.8–2.4 mm). It provided flow arrest in 100% of cases with no cases of reflux of embolic material. Balloon “jump back” was found to occur in 44.4% (4/9) of cases. Seven out of nine cases used Onyx, and two cases used n-butyl cyanoacrylate. Conclusions The Scepter Mini is a new dual lumen balloon ideal for distal access and can be used for embolization with liquid embolic agents with a high degree of technical success. Its great benefit is the immediate and safe flow arrest of distal vasculature upon balloon inflation. One important consideration for effective embolization is early identification of balloon jump back.

Scepter mini assisted angiographic cure of a Vein of Galen Malformation with n-butyl cyanoacrylate

Background Even in the modern endovascular era, the treatment of Vein of Galen Malformations (VOGM) is extremely challenging. While their natural history is very poor, endovascular embolization has emerged as the standard of care. These lesions often require multiple treatment sessions to decrease shunting, with each treatment including multiple pedicles. Here we present the first reported use of the Scepter Mini (Microvention, Aliso Viejo, CA) in the treatment of vein of Galen malformations. Clinical presentation A 7 month old female presented with an enlarging VOGM that was initially identified on prenatal ultrasound. Given the enlarging size of the lesion and failure to meet developmental milestones, the patient underwent planned endovascular embolization of the VOGM. The novel Scepter Mini balloon catheter was used for treatment of this lesion affording easy access to the target pedicle and immediate flow arrest which allowed for immediate cure of the lesion. Conclusion The novel Scepter Mini Balloon (Microvention, Aliso Viejo, CA) afforded excellent distal access with subsequent immediate flow arrest therefore facilitating endovascular cure. Initially, a staged approach was favored for the treatment of the lesion, but the flow arrest achieved by the Scepter mini facilitated immediate occlusion from a single pedicle.

“…5 , 15 , 16 A recent study also describes use of SMB in brain arteriovenous malformations. 17 Utilizing dual lumen balloon microcatheters for liquid embolic injection has been shown to be associated with reduced fluoroscopic times and better penetration of targeted nidus with liquid embolic system, as well as lower instances of microcatheter entrapment. 7 , 18 However, the majority of vascular pedicles that are embolized in cerebrovascular malformations are less than 3 mm in size.…”

Background The use of compliant dual lumen balloon microcatheters (CDLB) for the endovascular treatment of vascular malformations, wide neck aneurysms, and intracranial angioplasty (for vasospasm) is well documented. Navigation of 4 mm or larger CDLB within tortuous and small distal intracranial vessels can be challenging. Recently, the lower profile Scepter Mini balloon microcatheter (SMB) has been approved for use, with potential for improved intracranial navigation. Objective Discuss operative experience of Scepter Mini (Microvention, Aliso Viejo, CA). Methods We describe our initial experience with the SMB in a series of nine patients. Results The balloon microcatheter was used for delivery of liquid embolic in six patients (Case 1, 2, 6–9), adjunct support for delivery or positioning of the Woven Endobridge (WEB) device in two (Case 3,4), and gentle post-deployment repositioning of a WEB device in the last one (Case 5). We were able to successfully navigate the SMB over a 0.008 “micro wire to the target lesion in all the patients. We experienced initial difficulty with injecting liquid embolic in Case 2. We postulate that the SMB was in a tortuous segment of a dural vessel in this patient, and that it kinked on inflation with occlusion of the liquid embolic delivery lumen; this was overcome with slightly proximal repositioning and reinflation of the SMB. Conclusion Our initial experience shows that the SMB has potential to be useful in endovascular neurosurgical procedures requiring balloon assistance within smaller diameter blood vessels.
