AbstractWe report the case of a 15-year-old male patient with polyarteritis nodosa who presented with ruptured lenticulostriate artery (LSA) aneurysm and was successfully treated with endovascular N-butyl-2-cyanoacrylate (Histoacryl, B. Braun, Melsungen, Germany) acrylic glue embolization. Selective catheterization of LSA is sometimes difficult even with a low-profile microcatheter (Magic 1.2 FM, Balt Extrusion, Montmorency, France) due to acute angulation at the origin of the artery. In this 2-dimensional video illustration of the roadmap in digital subtraction angiography, reproduced after informed consent of the patient, we illustrate the balloon blocking technique to safely and effectively navigate the microcatheter through the small perforator with difficult angulation at the origin. A Magic microcatheter was passed via a distal access catheter 070 (Concentric Medical, Mountain View, California, USA) 105 cm in the internal carotid artery. The Magic microcatheter advancement was supported with a 0.008-inch guidewire (Hybrid 008, Balt Extrusion, Montmorency, France). Initial catheterization of LSA even with a low-profile Magic microcatheter was difficult as the origin of LSA was acute angled. While trying the navigate the microcatheter into the perforator, it was continuously flopping into the distal M1 segment of the middle cerebral artery. The balloon microcatheter (Scepter XC 4 × 11mm, Microvention, Tustin, California, USA) was passed separately via 5 French Envoy guiding catheter (Codman, Raynham, Massachusetts, USA) 100 cm in the proximal ICA using a contralateral left femoral artery puncture. The Balloon microcatheter advancement into the middle cerebral artery was supported with a Traxcess 0.014-inch microguidewire (Microvention). It was then inflated just beyond the origin of LSA which provided support to the magic microcatheter and thus allowing its easy navigation into the LSA. Super-selective microcatheter injection confirmed filling of the LSA aneurysm. A dilute 33% concentration of the liquid embolic agent N-butyl-2-cyanoacrylate mixed with Lipiodol (Guerbet, Aulnay-sous-Bois, France) was injected slowly under direct vision. The final-check angiogram revealed complete occlusion of the aneurysm (Video 1). Patient underwent craniotomy and hematoma evacuation 1 day after the procedure in view of his rapidly deteriorating neurological status. He was later discharged with Modified Rankin Scale of 3. Follow up angiography after 3 months showed completely occluded aneurysm (Video 2).Copyright © 2020 Elsevier Inc. All rights reserved.
