Despite advancements in diagnostic modalities, including Doppler ultrasound, computed tomography, magnetic resonance imaging, and invasive techniques like phlebography, there is still no globally accepted diagnostic algorithm, leading to inconsistencies in diagnosis. Moreover, due to the lack of standardized treatment guidelines, the optimal management of anterior NCS remains a topic of debate. While conservative management is usually recommended in the pediatric population, invasive treatments-including surgical options like LRV transposition and renal autotransplantation, as well as interventional radiology procedures like stenting, present challenges such as stent migration, restenosis, and long-term material durability.

The choice of approach depends on whether a 4-Fr catheter can be advanced into the pseudoaneurysm cavity. If feasible, the PseuSeal Snare is selected; otherwise, the PseuSeal Rendezvous is employed. In the PseuSeal Snare, a snare is deployed from a 4-Fr catheter within the pseudoaneurysm cavity. An 18-gauge needle is then used to retrogradely puncture the snare loop. A 0.035-inch guidewire is passed through the needle lumen, captured by the snare, and externalized. In the PseuSeal Rendezvous, an 18-gauge needle retrogradely punctures the guidewire within the cavity, and the guidewire is advanced into the needle lumen for externalization. After externalizing the guidewire in both approaches, an ExoSeal-specific sheath is inserted over the guidewire through the pseudoaneurysm neck into the main vessel. A balloon is advanced from the crossover sheath into the main trunk to cover the pseudoaneurysm ostium. The ExoSeal system is then inserted through the second sheath. As the ExoSeal's indicator wire is withdrawn, the balloon is inflated to stabilize the indicator wire, ensuring precise deployment of the PGA plug at the pseudoaneurysm neck.

Various options for the management of the BPCF including surgery and bronchoscopic occlusion were considered however an IR approach was planned. Plan was for vascular plug occlusion with/without glue embolization of the apico-posterior segmental bronchus. A 6F sheath was placed under direct vision and a 12 mm CERA plug was deployed. After plain plug occlusion, there were no signs of air leak. Various options for management including surgery and bronchoscopy procedures are limited in patients with poor pulmonary reserve. The IR approach offers the advantage of doing the procedure under real-time fluoroscopy, and no airway compromise. However, literature describes the use of glue to seal the interstices of the device which if not sealed was a cause of recurrence later. In our case, we report the percutaneous use of a CERA vascular plug as the sole device, especially since it has a polytetrafluoroethylene (PTFE) membrane which ensures occlusion, in addition to its titanium nitride coating which improves epithelialization. This ensures sustained occlusion as the sole agent, unlike other devices including the Amplatzer vascular plug.</p><p><strong>Conclusions: </strong>This highlights the relatively easy percutaneous route and the first report of CERA vascular plug usage for managing a case of broncho pleural cutaneous fistula.</p>","PeriodicalId":52351,"journal":{"name":"CVIR Endovascular","volume":"8 1","pages":"22"},"PeriodicalIF":1.2,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11914634/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143651980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
