During surgery for brain tumors, neurosurgeons often need to open the covering of the brain (the dura) to reach the tumor. At the end of the operation, this covering is carefully closed again. In some cases, the closure might not be completely adequate leading to cerebrospinal fluid leak. This leakage may collect under the scalp or flow out through the surgical wound. When this happens, the surgical wound may not heal properly, and the risk of infection can increase. These complications can delay recovery and may postpone additional treatments, such as radiotherapy or chemotherapy, that are often needed after brain tumor surgery. Although cerebrospinal fluid leakage is less common after supratentorial craniotomy (surgery on the upper part of the brain) than after other types of brain surgery, it remains a challenging complication and has not been well studied in this group of patients. The aim of this study is to determine how often cerebrospinal fluid leakage occurs after supratentorial craniotomy for intracranial tumors, identify factors that increase the risk of leakage, and evaluate how these leaks are managed. Understanding these factors may help reduce the occurrence of cerebrospinal fluid leakage and improve postoperative recovery in the future.",[26,27,28,29,30,31,32],"Brain Tumor Adult","Brain Tumor Benign","CerebroSpinal Fluid (CSF) Leak","Craniotomy","Glioblastoma","Glioma","Meningioma",[34,35,36,37,38],"intracranial tumor","cerebrospinal fluid leak","supratentorial craniotomy","glioma","meningioma","RECRUITING","2026-05-19",{"date":42,"type":43},"2026-05-22","ACTUAL",{"date":45,"type":43},"2026-02-03",{"date":47,"type":21},"2028-04",{"name":49,"class":50},"Medical University of Warsaw","OTHER",1,{"id":53,"slug":54,"hasResults":11,"nctId":55,"briefTitle":56,"officialTitle":57,"acronym":58,"eligibilityCriteria":59,"healthyVolunteers":11,"sex":17,"minAge":18,"maxAge":4,"enrollmentInfo":60,"targetDuration":4,"studyType":62,"phases":63,"briefSummary":65,"conditions":66,"keywords":67,"overallStatus":39,"whyStopped":4,"lastUpdateSubmitDate":72,"lastUpdatePostDateStruct":73,"startDateStruct":75,"completionDateStruct":77,"leadSponsor":79,"locationsCount":51},"100609559","noseal-trial-comparing-sealants-versus-no-sealant-for-preventing-csf-leak-after-endonasal-skull-base-surgery-100609559","NCT07216157","NoSeal Trial: Comparing Sealants Versus No Sealant for Preventing CSF Leak After Endonasal Skull Base Surgery","The NoSeal Trial - Nasal Outcome Study Evaluating Artificial Leak-Sealing: A Prospective, Randomized, Controlled, Single-Blinded, Single-Center Clinical Trial Comparing Fibrin Glue (Tisseel®) and a Two-Component Synthetic Polymer Sealant (PEI\u002FPEG, Adherus®) Versus No Sealant for the Prevention of Cerebrospinal Fluid Leak and Promotion of Wound Healing Following Endonasal Skull Base Surgery, Designed in Accordance With the SPIRIT 2025 Guidelines","NoSeal","Inclusion Criteria:\n\n* Age ≥ 18 years\n* Scheduled for endoscopic endonasal surgery involving standard skull base reconstruction\n* Informed written consent obtained prior to enrollment\n* Hemodynamic and electrolyte stability before surgery\n* Procedure expected to be completed without use of high-flow intraoperative CSF diversion techniques\n\nExclusion Criteria:\n\n* Revision surgery or extended endoscopic approaches requiring complex reconstruction (e.g., clival or cribriform defects)\n* Tumors requiring complex sella reconstruction from the start\n* Preoperative hydrocephalus\n* Known allergy to fibrin-based or synthetic sealant components\n* Active sinus infection or systemic inflammatory disease\n* Prior radiotherapy to the sellar or parasellar region\n* Uncontrolled diabetes mellitus (HbA1c \\> 7.0%)\n* Participation in another interventional trial that may influence wound healing or CSF assessment\n* Radiologic signs of chronic intracranial hypertension or hypotension",{"count":61,"type":21},225,"INTERVENTIONAL",[64],"NA","Postoperative cerebrospinal fluid (CSF) leak is a significant complication of endoscopic endonasal approaches (EEA) to the skull base. The use of tissue sealants such as fibrin glue (Tisseel) or synthetic agents (PEI\u002FPEG) is widespread in surgical practice, however, recent high-quality evidence challenges their clinical benefit and cost-effectiveness. This study aims to investigate whether the routine use of sealants in patient with peri-operatively assessed low CSF leak risk, significantly improves outcomes over no sealant use, to guide more cost- effective, evidence-based closure strategies. To the best of our knowledge, the present study is the first randomized clinical trial to evaluate the necessity and comparative effectiveness of fibrin and synthetic sealants versus no sealant in preventing postoperative CSF leaks following endoscopic endonasal surgery in low-post operative CSF leak risk patients.",[28],[68,69,70,71],"csf","pituitary adenoma","csf leak","sealant","2025-10-09",{"date":74,"type":43},"2025-10-14",{"date":76,"type":43},"2025-08-15",{"date":78,"type":21},"2027-03-15",{"name":80,"class":50},"Maria Sklodowska-Curie National Research Institute of Oncology",{"id":82,"slug":83,"hasResults":11,"nctId":84,"briefTitle":85,"officialTitle":85,"acronym":86,"eligibilityCriteria":87,"healthyVolunteers":11,"sex":17,"minAge":4,"maxAge":4,"enrollmentInfo":88,"targetDuration":90,"studyType":23,"phases":4,"briefSummary":91,"conditions":92,"keywords":93,"overallStatus":39,"whyStopped":4,"lastUpdateSubmitDate":104,"lastUpdatePostDateStruct":105,"startDateStruct":107,"completionDateStruct":109,"leadSponsor":111,"locationsCount":51},"100570783","the-freiburg-registry-on-spontaneous-intercranial-hypotension-sih--post-dural-puncture-headache-pdph-100570783","NCT06711731","The Freiburg Registry on SpontanEous IntercrAnial Hypotension (SIH) & Post-duraL Puncture Headache (PDPH)","SEAL","Inclusion Criteria:\n\n1.

The multitude of symptoms, and their inconsistency over time are just two of many challenges preventing timely diagnosis and treatment in many patients.\n\nSpinal CSF leaks can occur after intentional or accidental dural puncture (post-dural puncture headache - PDPH) or spontaneously (spontaneous intracranial hypotension - SIH). Awareness is steadily increasing with simultaneous increase of recognized patients. Yet, research and diagnostic is mainly provided by few specialized centers, as e.g. Freiburg. Thus, many observations point towards a large non-diagnosed and non-recognized number of patients, most likely being misdiagnosed and mistreated.\n\nObjective: The aim of the registry is to collect structured information on the frequency, cause, symptoms, diagnostic procedures, treatment options and long-term outcome.
