This report presents 3 cases of persistent T2EL with aneurysm growth after TEVAR, and managed through endovascular embolization using flow-directed microcatheters and 0.010-inch guidewires, employing N-butyl cyanoacrylate (NBCA) either alone or in combination with coils. Aneurysmal sac embolization was successfully performed in all cases, despite significant vascular tortuosity, resulting in favorable immediate outcomes without complications. A key advantage observed was the ability of flow-directed microcatheters to navigate into distal, tortuous feeding vessels that are typically inaccessible using conventional methods. While NBCA alone was effective for embolizing small sacs, a combination of coils and NBCA provided more controlled and stable embolization in larger sacs. However, follow-up computed tomography revealed new endoleaks in 2 cases, emphasizing the need for continued monitoring. While short-term results are promising, further studies are needed to assess long-term recurrence risks. This case series highlights the effectiveness of flow-directed microcatheters, 0.010-inch microwires, and targeted embolization techniques in managing T2EL following TEVAR.</div></div>","PeriodicalId":53472,"journal":{"name":"Radiology Case Reports","volume":"21 1","pages":"Pages 1-8"},"PeriodicalIF":0.0,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145223656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report the first known case of symptomatic cystic adenomyosis successfully treated using transcervical intrauterine ultrasound-guided radiofrequency ablation (RFA). A 35-year-old woman with severe dysmenorrhea, hypermenorrhea, and a 2.5 cm cystic adenomyotic lesion located deeply within the anterior myometrium underwent combined transcervical RFA (Sonata System) and laparoscopic excision of superficial peritoneal endometriosis. Real-time intraoperative ultrasound enabled safe and precise ablation with minimal myometrial injury. Six-month postoperative follow-up demonstrated complete resolution of the cystic adenomyosis and significant symptomatic relief, with only minimal residual scar tissue. Compared to conventional surgical methods, transcervical RFA offered substantial advantages including minimal invasiveness, preservation of uterine architecture, rapid recovery, and fertility preservation.
