The use of dual-lumen balloon for embolization of peripheral arteriovenous malformations

Özet

PURPOSEWe aimed to evaluate the safety and feasibility of the embolization of peripheral arteriovenous malformation (AVM) with non-adhesive liquid agents (NALA) injected by dual-lumenballoons (DLB).METHODSWe conducted a multicenter retrospective study between January 2017 and June 2019, including patients with peripheral AVM embolized with NALA by DLB. Fourteen patients wereincluded. The AVM classification, technical and clinical success were evaluated, as were nidussize, liquid agent used, volume and time of injection in DLB, complications, follow-up andneed of surgical intervention.RESULTSThe mean age of the patients was 37±22.5 years (range, 6–82 years). The mean nidus sizewas 5.2±2.4 cm (range, 3.0–12.0 cm). By Schobinger classification, 11 AVMs were classified instage 3 and 3 AVMs were classified in stage 2. By Cho’s classification, 2 AVMs were in stage II, 4AVMs were in stage I, 4 AVMs were in stage IIIa and 4 AVMs were in stage IIIb. Onyx was usedin 11 patients (78.6%), while Squid, PHIL, and both Onyx and Squid were used in one patienteach (7.1%). Seven patients (50%) required one session of embolization, 4 patients (28.6%)required two, 2 patients (14.3%) required three and 1 patient (7.1%) required four sessions.Complete nidus exclusion was achieved in 11 patients (78.6%), optimal clinical response in12 patients (85.7%). Four patients (28.6%) exhibited minor complications, all controlled. Nomajor complications were seen. Four patients underwent surgical intervention (28.6%).CONCLUSIONThe embolization of peripheral AVM with NALA in DLB appears to be safe and feasible, achieving high rates of technical and clinical success.
