Microcatheter looping facilitates access to both the acutely angled parent artery and XXXX for effective embolization.

@entity439 with an acutely angled parent artery are difficult to access for coiling. This study aimed to investigate the safety and effectiveness of microcatheter looping for embolization of @entity438 with access difficulty. Ten @entity1 (male:female=5:5) with @entity438 treated with the microcatheter looping technique were analyzed retrospectively. The parent artery formed an acute angle with the major artery in five @entity439 . The microcatheter was looped into a "a" loop for treatment in the anterior temporal artery @entity439 and a "U" loop in the remaining nine @entity439 . All ten @entity439 were successfully treated with the microcatheter looping technique. The microcatheter tip was successfully navigated into the @entity439 sac and remained stable throughout the embolization process. All @entity439 were occluded with @entity432 in five and near- @entity432 in five, and the parent artery remained patent in all cases. No complications occurred peri-procedurally. The Glasgow Outcome Scale was 5 in all @entity1 before discharge. Follow-up angiography six to 12 months later revealed a good occlusion status of the @entity439 . The microcatheter looping technique is effective when the conventional embolization technique fails to treat @entity438 with difficult access especially when the parent artery forming an acute angle with the major artery exacerbates difficult access to the @entity439 .
