RESUMEN
Background Cavernous sinus (CS) invasion is found in 1520% of pituitary adenomas; it represents a poor prognosis factor and a surgical challenge even in experienced pituitary centers. We present our experience and technical note description for surgical management of pituitary adenomas with CS invasion in acromegaly by the transsellar lateral approach with an endoscopic endonasal transsphenoidal route. Method prospective case series of patients who underwent endoscopic endonasal surgery for Growing Hormone (GH) producing adenomas with CS invasion treated at the Neurosurgery departments of National Institute of Neurology and Neurosurgery in Mexico City, and of Toluca Medical Center of Social Security Institute of the State of Mexico and Provinces between January 2014 and March 2019. Results Thirty-two of 94 patients with diagnosis of pituitary adenoma treated at our institutions (34%) had acromegaly; thirteen of patients with acromegaly diagnosis met the inclusion criteria for CS invasion. Postoperative images reported gross total resection in 10 patients (76.9%). Mean follow-up time was 28.3 months. Remission criteria were achieved in nine patients (69.2%), with one of these patients (11.1%) having recurrence during follow up. All patients with no biochemical remission had improvement in GH and IGF profiles. Three patients without remission underwent radiosurgery (14Gy), and one patient had remission after the procedure. Conclusions We consider this to be a safe and efficient approach for tumors invading CS, when surgical team have good experience in endoscopy of the skull base and reconstruction techniques, appropriate instruments are available, and tumor has soft consistency (AU)
Antecedentes Se encuentra invasión al seno cavernoso en el 15-20% de los adenomas hipofisiarios, y representa un factor de mal pronóstico, así como un reto quirúrgico en algunas series. En el presente trabajo describimos y evaluamos nuestra experiencia con una técnica quirúrgica para el manejo de adenomas hipofisiarios con invasión al seno cavernoso en pacientes con acromegalia a través de un abordaje transelar lateral por la vía endonasal endoscópica. Métodos Serie de casos prospectiva de pacientes tratados con cirugía endonasal endoscópica para pacientes con diagnóstico de acromegalia y adenomas hipofisiarios con invasión al seno cavernoso tratados en los Departamentos de Neurocirugía del Instituto Nacional de Neurología y Neurocirugía en la Ciudad de México y en el Centro Médico Toluca del Instituto de Seguridad Social del Estado de México y Municipios entre enero del 2014 y marzo del 2019. Resultados Treinta y dos pacientes de 94 con diagnóstico de adenoma hipofisiario fueron tratados en nuestras instituciones, cumplieron con criterios clínicos y bioquímicos para el diagnóstico de acromegalia (34%); de estos, 13 pacientes cumplieron con criterios por imagen y quirúrgicos de invasión al seno cavernoso (40,6%). Las imágenes postoperatorias mostraron resección completa en 10 pacientes (76,9%). El tiempo medio de seguimiento fue de 28,3 meses. Se alcanzó un índice de remisión bioquímica en el 69,2% de los casos, con un paciente presentando recurrencia durante el seguimiento. Tres de los pacientes sin remisión bioquímica fueron sometidos a radiocirugía, con respuesta terapéutica en uno de ellos (AU)

ABSTRACT: Cerebrospinal fluid (CSF) leakage caused by skull base fracture represents high risks of bacterial meningitis, and a rate of mortality of 8.9%. Endoscopic endonasal repair of CSF leaks is quite safe and effective procedure with high rates of success. The aim of this study is to describe our technique for management of skull base CSF leaks secondary to craniofacial trauma based on the anatomic location of the leak. This is a retrospective case series of 17 patients with diagnosis of craniofacial trauma, surgically treated with sole endonasal endoscopic and combined endonasal/transcranial approaches with diagnosis of CSF leak secondary to skull base fractures. Seventeen patients met inclusion criteria for this study. Mean age was 46âyears old. Most common etiology was motor vehicle. Early surgery was performed in 8 patients, and late surgery in 9 patients. The most common site of CSF leak was at ethmoid cells or at the fronto-ethmoid junction in 9 patients. Thirteen patients (76.4%) were treated only with endonasal endoscopic technique, and 4 (23.5%) with hybrid surgery, combining endonasal endoscopic and cranial bicoronal approaches with nasal and pericranial vascularized flaps, and nasal mucosal free flaps. Mean hospital stay was 23.7âdays.The mean follow-up time was 25.6âmonths. When surgical reconstruction is indicated for CSF leaks secondary to skull base fractures, endonasal endoscopic techniques should be part of the surgical management either as a sole procedure, or in combination with classical transcranial approaches with high rates of success and low morbidity.
