The treatment of ACF by an occluder device deployment is a rare but increasingly common approach. We report a case of ACF secondary to ruptured AAA treated with an occluder device after endograft deployment. A 66-year-old male was treated in an emergent setting for a ruptured AAA with ACF deploying aorto-bi-iliac endograft. At 3-month computed tomography angiography (CTA), the persistence of aorto-caval communication and the increased sac reperfusion (type II endoleak) from the lumbar and inferior mesenteric artery were detected. Under local anesthesia and through percutaneous left brachial arterial access and percutaneous right femoral venous access, a 7-mm Amplatzer Septal Occluder was deployed with the \"left\" atrial end in the aneurysmal sac and the \"right\" atrial end in the inferior vena cava. The adjunctive embolization of the aneurysmal sac was performed. The post-procedural CTA and 6-month contrast-enhanced ultrasound confirmed the disappearance of endoleak and the exclusion of ACF. A systematic review of the literature according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement was conducted regarding the use of occluder devices to treat ACF (PROSPERO; CRD42024512167). Including the current case, 10 patients (male 100%; age range 24-74 years) in 10 publications were found. ACF after trauma and after AAA rupture was described in 6 and 4 patients, respectively. Occluder device deployment was a primary procedure in 6/10 cases and a secondary intervention in 4/10 cases. Different types of occluder devices (vascular 4/10, atrial septal 3/10, duct 2/10, ventricular septal 1/10) were used. Technical success was 100%, with no intraoperative complications. Postoperative complications occurred in 2/10 patients (vascular plug migration and iliac deep vein thrombosis). Three out 10 patients required reintervention within 30 days for persistent patency of ACF (1 endovascular abdominal aneurysm repair, 1 re-embolization of fistula with coils, 1 patient underwent adjunctive septal occluder device and iliolumbar embolization). In 8/10 patients (length of follow-up: 1-80 months), no residual arterio-venous communication. In 3 patients with AAA, aneurysm shrinkage occurred in 3/3 patients, with type II endoleak in 1 case. Although a scarce number of patients are available in the literature, occluder device deployment into abdominal arterio-venous fistula is feasible. For a traumatic ACF, the occluder device deployment could be proposed as the primary treatment, while, after a ruptured AAA, endograft deployment is mandatory.Clinical ImpactThe use of occluder device for the occlusion of an aorto-caval fistula (ACF) is an off-label technique reported in literature. The technical success mainly depends from the type of deployed occluder device.

Postoperative renal function remained stable across all patients.</p><p><strong>Conclusion: </strong>CO₂ CBCT is a feasible and effective alternative for completion imaging in complex FEVAR procedures for patients with CKD, potentially reducing the need for iodine contrast and the associated risk of nephropathy. A standardized CO₂ protocol can enhance procedural safety. Further research with larger cohorts is needed to confirm these findings.Clinical ImpactCO₂ serves as the preferred contrast medium for the endovascular treatment of patients with iodine contrast allergies or those afflicted with chronic kidney disease (CKD) to preserve further renal deterioration. Ensuring protection from potentially harmful substances is paramount during endovascular repair in such patients. Equally crucial is performing the procedure safely through a standardized protocol and confirming its accuracy upon completion. Nevertheless, the possibility of employing CO₂ for cone beam computed tomography provides invaluable insights into procedural efficacy, thereby enhancing outcomes for CKD patients undergoing complex endovascular repair.</p>","PeriodicalId":50210,"journal":{"name":"Journal of Endovascular Therapy","volume":" ","pages":"15266028251327041"},"PeriodicalIF":1.7,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143651645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Also, the optimal approach for DCB-based revascularization of peripheral artery diseases still remains undefined. This study was designed to explore the in vivo pharmacokinetic and histopathological effects of DCBs using Ranger and 4 Chinese DCBs after implantation and administration in New Zealand rabbits.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Materials and methods: &lt;/strong&gt;Fifty New Zealand rabbits were divided into 5 groups with 10 rabbits in each group according to the DCB used: Ranger (Boston Scientific), Orchid (Acotec), Reewarm (Endovastec), Ultrafree (Zylox), and Yaohang (Polyrey). After being guided to the lower segment of the abdominal aorta, the DCB was inflated for 3 minutes. Plasma, inflated infrarenal aorta, vastus lateralis muscle, anterior tibial muscle, and right toes were harvested for histological and paclitaxel concentration analyses 4 hours or 28 days after the angioplasty.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;At 4 hours after aortic angioplasty, the overall paclitaxel concentrations in aortic wall were not statistically different (p = 0.050), but the paclitaxel concentrations in vastus lateralis muscle (p = 0.002), anterior tibial muscle (p = 0.006) and toe (p &lt; 0.001) were not totally same according to the results of Kruskal-Wallis test. In toe, concentrations of paclitaxel were significantly lower for the Ranger (120.8 ng/g) DCB than for the Orchid (1880 ng/g; p = 0.008), Reewarm (347 ng/g; p = 0.016), and Ultrafree (261 ng/g; p = 0.016) DCBs. Concentrations of paclitaxel in the toe were not statistically different between Ranger and Yaohang DCBs (p = 0.421). Neointimal area (p &lt; 0.001), neointimal thickness (p &lt; 0.001), and percentage of luminal stenosis (p &lt; 0.001) were less for Ranger DCB than for other DCBs 28 days after aortic angioplasty. The differences in paclitaxel concentrations in tissues 28 days after aortic angioplasty were not statistically significant.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;Different design concepts will make a difference in the in vivo pharmacokinetic and histopathological effects of DCBs. The Ranger DCB can achieve similar drug delivery efficiency as other higher-dose DCBs and fewer neointimal hyperplasia. Although clinical implications remain to be further investigated, the present results may provide implications for the design and use of DCBs.Clinical ImpactThe current preclinical study suggested that different design concepts would make a difference in the pharmacokinetic and histopathological effects of drug-coated balloons (DCBs). Though Ranger DCB had the lowest paclitaxel loading in this study, it still achieved similar drug delivery efficiency with other higher-dose DCBs. Also, neointimal hyperplasia was less for the Ranger DCB than for the other DCBs 28 days after aortic angioplasty.
