Traditional epidural blood patch treatment is often ineffective, especially in refractory cases without a source leak identified. This study introduces and evaluates the Catheter-Assisted Sealing Technique (CAST), a novel neurointerventional approach for refractory SIH. CAST involves targeted or diffuse delivery of fibrin glue into the epidural space to repair CSF leaks.MethodsA retrospective case series of ten patients with refractory SIH underwent CAST using a fluoroscopy-guided epidural catheter approach. Clinical symptom resolution and follow-up MRI findings were assessed.ResultsNine of 10 patients achieved complete headache resolution and associated symptom relief. One patient experienced significant improvement without complete relief. Follow-up MRI showed resolution of pachymeningeal enhancement in all patients. One patient required repeat procedures for recurrent symptoms. No neurological injury or spinal cord compression occurred, with the only complication being transient femoral nerve palsy due to positioning that resolved within four months.ConclusionCAST is a promising, minimally invasive alternative for refractory SIH. It enables targeted or diffuse fibrin sealant application, providing a seemingly effective leak closure even in cases of occult or multifocal leaks. Early results show high success and safety rates, but larger cohorts and extended follow-up are needed to validate it as a standard treatment.","PeriodicalId":49174,"journal":{"name":"Interventional Neuroradiology","volume":" ","pages":"15910199251376452"},"PeriodicalIF":2.1,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12484073/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145201033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Radial artery spasm (RAS) is the most common complication of TRA. Under severe RAS conditions, pulling a catheter may occasionally result in radial artery injury and emergency surgery may be required. There have been no reports on the behavior of entrapped catheters/sheaths when pulled under severe RAS conditions. We conducted tensile tests on guide sheaths and balloon guide catheters to observe their damage in vitro and evaluate their potential to cause vascular injury.MethodsSix types of guide sheaths and balloon guide catheters were used in the test. The catheters were fixed to the testing machine and pulled. We observed how the catheter stretched and fractured. Additionally, a stress-strain curve was obtained from each examination to compare the characteristics of the catheters.ResultsCatheters were damaged in various ways. Some catheters were simply lengthened, whereas others were partially or completely torn. In the evaluation of the stress-strain curves, the slopes of the curves were almost equal among the catheters at the beginning of the test; that is, the hardness was almost the same for each catheter. As the strain increased, each exhibited different behavior.ConclusionCatheters can be damaged in various ways by stretching, which can cause vascular injuries. Neurointerventionists should be aware of possible catheter damage and vascular injury when catheters are entrapped.","PeriodicalId":49174,"journal":{"name":"Interventional Neuroradiology","volume":" ","pages":"15910199251384074"},"PeriodicalIF":2.1,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12484055/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145200971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In these cases, standard surgical evacuation may be contraindicated if intracranial pressure is not corrected, increasing the risk of complications. While middle meningeal artery embolization (MMAE) has emerged as a treatment option for refractory CSDH, its role in CSF-hypovolemia associated CSDH remains underexplored.MethodsThis retrospective study included seven patients with radiographically confirmed, symptomatic CSDH due to CSF hypovolemia. Etiologies included VP shunt overdrainage (n = 6) and SIH (n = 1). Prior to MMAE, all patients underwent definitive treatment of the underlying cause-either shunt adjustment or ligation, or targeted epidural blood patch. Embolization was performed using 250 μm microspheres via the middle meningeal artery. Patients were followed clinically and with serial CT imaging.ResultsAll patients demonstrated neurological improvement within several days following embolization. Hematoma thickness progressively decreased over a period of 2 to 6 months, with complete or near-complete resolution in all cases. No patients experienced recurrence or required surgical evacuation. There were no procedural complications.ConclusionMMAE, when performed after correction of the underlying CSF hypovolemia, appears to be a safe and effective therapeutic option for CSDH.
