Abstract
Background: Cerebrospinal fluid (CSF) leakage frequently complicates endoscopic endonasal transsphenoidal pituitary resections, despite the use of lumbar drains, nasoseptal flaps, or commercial dura sealants. Managing this complication often requires revision surgery and increases the risk of infection. Platelet-rich fibrin (PRF), an affordable autologous biomaterial derived from the patient's blood through short, angulated centrifugation, contains growth factors and leukocytes embedded in a fibrin matrix. PRF exhibits regenerative properties in various surgical disciplines. This study assesses a three-layer sellar reconstruction method employing solid membranous (s-PRF) and high-viscosity injectable (i-PRF) forms of PRF.
Materials and methods: We present our initial experience on a series of 22 patients with pituitary macroadenomas. For all patients, an endoscopic transnasal transsphenoidal approach was selected. Following the resection of the pathology, sellar reconstruction was accomplished using a three-layer orthobiologic technique. A membranous s-PRF was utilized as an inlay inside the opened sellar floor, followed by a layer of injectable i-PRF finally covered with another s-PRF membrane over the top to the sellar corridor.
Results: In all cases the implementation of the proposed three-layer PRF reconstruction strategy was feasible and safe. During the 12-month follow-up period there were no adverse effects reported associated with the PRF application. 77% (17/22) of the patients demonstrated intraoperatively a cerebrospinal fluid (CSF) leak (Esposito Grade 1-3). In total, the proposed PRF reconstruction effectively prevented postoperative CSF leaks in 95% of the patients and in 94% of those with an Esposito Grade 1-3. One of the two patients with intraoperative Esposito Grade 3 developed a CSF leak on the first postoperative day, which was successfully managed with a lumbar drain for 5 days.
Conclusion: Sellar reconstruction after endoscopic endonasal transsphenoidal resection of pituitary adenomas with PRF is feasible and safe. The three layer PRF augmentation is a novel technique to prevent CSF-leakage.
期刊介绍:
Evidence of surgical interventions go back to prehistoric times. Since then, the field of surgery has developed into a complex array of specialties and procedures, particularly with the advent of microsurgery, lasers and minimally invasive techniques. The advanced skills now required from surgeons has led to ever increasing specialization, though these still share important fundamental principles.
Frontiers in Surgery is the umbrella journal representing the publication interests of all surgical specialties. It is divided into several “Specialty Sections” listed below. All these sections have their own Specialty Chief Editor, Editorial Board and homepage, but all articles carry the citation Frontiers in Surgery.
Frontiers in Surgery calls upon medical professionals and scientists from all surgical specialties to publish their experimental and clinical studies in this journal. By assembling all surgical specialties, which nonetheless retain their independence, under the common umbrella of Frontiers in Surgery, a powerful publication venue is created. Since there is often overlap and common ground between the different surgical specialties, assembly of all surgical disciplines into a single journal will foster a collaborative dialogue amongst the surgical community. This means that publications, which are also of interest to other surgical specialties, will reach a wider audience and have greater impact.
The aim of this multidisciplinary journal is to create a discussion and knowledge platform of advances and research findings in surgical practice today to continuously improve clinical management of patients and foster innovation in this field.
